Systematic review of endometriosis pain assessment: how to choose a scale?

Painful sexual intercourse, quality of life and sexual function in patients with endometriosis: not just deep dyspareunia

PURPOSE

To evaluate the prevalence of deep and superficial dyspareunia in women with diagnosis of endometriosis. Secondly, to assess the temporal relation between deep and superficial dyspareunia in women reporting both symptoms (concomitant dyspareunia) and the impact on quality of life (QoL) and sexual function.

METHODS

This is a cross-sectional cohort study that included fertile women with diagnosis of endometriosis. Enrolled subjects reported pain symptoms including dyspareunia and its temporal onset and completed two one-time validated questionnaires regarding sexual function (Female Sexual Function Index) and QoL (International QoL Assessment SF-36).

RESULTS

Among the 334 enrolled patients, 75.7% (95%) reported dyspareunia. Women were divided into four groups according to the presence and type of dyspareunia: isolated superficial dyspareunia (6.3%), isolated deep dyspareunia (26.0%), concomitant dyspareunia (43.4%) and no dyspareunia (24.3%). Women with concomitant dyspareunia reported higher NRS scores than women with isolated dyspareunia or no dyspareunia (P ≤ 0.001). The majority of women with concomitant dyspareunia (56.6%) reported that deep dyspareunia developed before superficial dyspareunia. Women with concomitant dyspareunia reported worse QoL and worse sexual function than women with isolated dyspareunia or without dyspareunia (P ≤ 0.001).

CONCLUSION

Dyspareunia is a common symptom in women with endometriosis, with many reporting concomitant deep and superficial dyspareunia. Concomitant dyspareunia can significantly impact sexual function and quality of life (QoL). Therefore, it is crucial to investigate dyspareunia thoroughly and differentiate between its types to tailor effective therapeutic strategies.

Lesion size and location in deep infiltrating bowel endometriosis: Correlation with gastrointestinal dysfunction and pain

INTRODUCTION

Presence of deep infiltrating bowel endometriosis (DE) is associated with occurrence of dyschezia and gastrointestinal symptoms. The degree of the disease, the lesion length, and the location, that is, lesion-to-anal-verge distance (LAVD) of DE, as well as the severity of the symptoms appear to be correlated. Nevertheless, it is not yet known to what extent the size and LAVD of bowel DE influence the severity of gastrointestinal symptoms. The present study aims to evaluate a possible correlation of lesion location (LAVD) and size (according to the #Enzian classification) with preoperative symptoms.

MATERIAL AND METHODS

In this prospective study, premenopausal patients with histologically confirmed DE undergoing modified limited nerve-vessel sparing rectal segmental bowel resection or full-thickness discoid resection were evaluated. Extent of endometriosis was defined according to the #Enzian classification during surgery. The primary outcome measure was the correlation between lesion size and location with the GI function impairment reflected by presurgical lower anterior resection syndrome (LARS) scores; the secondary outcome was differences in presurgical numeric rating scale pain scores of dyschezia, dyspareunia, and dysmenorrhea as well as the impact of concomitant DE of other locations on symptom intensity.

RESULTS

Of 162 consecutive patients, 151 were included in the final analysis. No significant correlation was observed between lesion size (#Enzian compartments C1/C2/C3) or LAVD and GI dysfunction reflected by LARS-like symptoms (p = 0.314 and p = 0.185, respectively) or pain symptoms (dyschezia, p = 0.440; dyspareunia, p = 0.136; and dysmenorrhea p = 0.221). Furthermore, no significant correlation was observed between lesion size and GI dysfunction when merging two severity grades (#Enzian compartments C1 plus C2 vs. C3; p = 0.611). In addition, LAVD did not affect the degree of dyschezia (p = 0.892), dyspareunia (p = 0.395), or dysmenorrhea (p = 0.705). Finally, the presence of concomitant DE lesions infiltrating the vagina/rectovaginal space (#Enzian compartment A) and/or sacrouterine ligaments/parametrium (#Enzian compartment B) did not alter the severity of preoperative dyschezia (p = 0.493) or dysmenorrhea (p = 0.128) but showed a trend toward affecting gastrointestinal function (p = 0.078) and was significantly associated with dyspareunia (p = 0.035).

CONCLUSIONS

In present study, we could not find a correlation between colorectal DE lesion size and location (LAVD) and gastrointestinal function impairment or intensity of dyschezia and dysmenorrhea. Additional involvement of vagina/rectovaginal space (#Enzian compartment A) and/or sacrouterine ligaments/parametrium (#Enzian compartment B) exerts a significant impact on the degree of dyspareunia in women with colorectal DE.

Pain after oocyte retrieval in women with endometriosis undergoing fertility preservation or IVF

RESEARCH QUESTION

Do women with endometriosis undergoing oocyte retrieval for fertility preservation experience the same level of pain as women undergoing oocyte retrieval for IVF?

DESIGN

This retrospective cohort study included 796 cycles in women with endometriosis undergoing oocyte retrieval for fertility preservation (n = 401) or IVF (n = 395) between January 2020 and October 2022. Post-operative pain assessments were compared between the two groups using a numeric rating scale (NRS).

RESULTS

Women in the fertility preservation group were younger (32.1 ± 4.2 years versus 35.1 ± 4.1 years; P < 0.001), had a lower body mass index (22.8 ± 3.9 kg/m2 versus 24.6 ± 4.4 kg/m2; P < 0.001) and had a lower concentration of anti-Müllerian hormone (1.8 ± 1.5 ng/ml versus 2.15 ± 2.11 ng/ml; P = 0.026) in comparison with women in the IVF group. The oestrogen concentration on the day of ovulation trigger was higher in women in the fertility preservation group (2188 ± 1152 pg/ml versus 2081 ± 995 pg/ml; P = 0.004), and the prevalence rates of adenomyosis and digestive endometrial lesions were lower in women in the fertility preservation group (14% versus 29%, P < 0.001; 16% versus 25%, P = 0.003, respectively) compared with women in the IVF group. After oocyte puncture, more women in the fertility preservation group had an NRS pain score >3 (moderate to severe pain) compared with women in the IVF group (20% versus 14%; P = 0.018). The progestin-primed ovarian stimulation (PPOS) protocol was identified as an independent predictive factor of greater post-operative pain (adjusted OR 2.30, 95% CI 1.06-5.15; P = 0.039).

CONCLUSION

Women with endometriosis undergoing fertility preservation reported more intense post-operative pain in the recovery room than women undergoing IVF. The PPOS protocol was an independent risk factor of intense pain (NRS pain score >3) in women with endometriosis, but further studies are needed to confirm this result.

Subgroups of pelvic pain are differentially associated with endometriosis and inflammatory comorbidities: a latent class analysis

ABSTRACT

Chronic pelvic pain is heterogeneous with potentially clinically informative subgroups. We aimed to identify subgroups of pelvic pain based on symptom patterns and investigate their associations with inflammatory and chronic pain-related comorbidities. Latent class analysis (LCA) identified subgroups of participants (n = 1255) from the Adolescence to Adulthood (A2A) cohort. Six participant characteristics were included in the LCA: severity, frequency, and impact on daily activities of both menstruation-associated (cyclic) and non-menstruation-associated (acyclic) pelvic pain. Three-step LCA quantified associations between LC subgroups, demographic and clinical variables, and 18 comorbidities (10 with prevalence ≥10%). Five subgroups were identified: none or minimal (23%), moderate cyclic only (28%), severe cyclic only (20%), moderate or severe acyclic plus moderate cyclic (9%), and severe acyclic plus severe cyclic (21%). Endometriosis prevalence within these 5 LCA-pelvic pain-defined subgroups ranged in size from 4% in "none or minimal pelvic pain" to 24%, 72%, 70%, and 94%, respectively, in the 4 pain subgroups, with statistically significant odds of membership only for the latter 3 subgroups. Migraines were associated with significant odds of membership in all 4 pelvic pain subgroups relative to those with no pelvic pain (adjusted odds ratios = 2.92-7.78), whereas back, joint, or leg pain each had significantly greater odds of membership in the latter 3 subgroups. Asthma or allergies had three times the odds of membership in the most severe pain group. Subgroups with elevated levels of cyclic or acyclic pain are associated with greater frequency of chronic overlapping pain conditions, suggesting an important role for central inflammatory and immunological mechanisms.

Rationale and design of a single-center randomized trial to compare the graft patency between the radial artery and the no-touch saphenous vein in coronary artery bypass grafting surgery (GRAFT-CAB Study)

BACKGROUND

Previous studies suggested only the radial artery and the No-touch (NT) technique were effective in reducing graft occlusion after coronary artery bypass grafting (CABG) surgery. However, there is no randomized trial comparing these 2 graft conduits. The optimum second conduit for CABG remains undetermined.

MATERIALS AND METHODS

This study is a prospective, single-center randomized clinical trial, aiming to compare the graft patency between the radial artery and the NT vein graft. All patients undergoing isolated CABG with left internal mammary artery (LIMA) plus at least 2 additional grafts will be considered eligible. About 774 cases (516 in the radial artery group and 258 in the NT vein group) will be enrolled in over 1 to 2 years. Participants will be randomized and allocated to two bypass strategies: the LIMA plus 1 radial artery and 1 conventional vein graft, or the LIMA plus 2 NT vein grafts. The primary outcome is graft occlusion at 1 year after CABG evaluated by CT angiography. The secondary outcomes include graft occlusion at 3 and 5 years and major adverse cardiac or cerebrovascular events at 1, 3, and 5 years follow-ups.

DISCUSSION

This study will define whether or not the NT vein has a lower graft occlusion rate than the radial artery in short and mid-term follow-ups, and provide new evidence for the second conduit choice in CABG surgery.

Evaluating the development of endometriosis and adenomyosis lesions over time: An ultrasound study of symptomatic women

INTRODUCTION

There is a gap in knowledge regarding development of endometriosis and adenomyosis lesions visible at transvaginal ultrasound. The objectives were to evaluate if women with symptoms suggestive of endometriosis or adenomyosis but normal ultrasound examination develop endometriosis or adenomyosis lesions visible at ultrasound over time and if alterations of symptoms over time are associated with ultrasound findings at follow-up.

MATERIAL AND METHODS

This was a prospective cohort study of 100 symptomatic women with normal initial ultrasound examination during 2014-2017 who underwent follow-up ultrasound examination in 2022. Symptoms suggestive of endometriosis were assessed using visual analog scale at both examinations and minimal clinically important difference of 10 mm was considered as a significant alteration. An examiner with expertise in advanced ultrasound examination of endometriosis performed transvaginal ultrasound examinations in accordance with the consensus protocol by the International Deep Endometriosis Analysis group.

RESULTS

At follow-up ultrasound examination of 100 women, 13 (13% [95% CI 7.1-21.2]) had visible endometriosis or adenomyosis lesions, 8 (8% [95% CI 3.5-15.2]) had endometriosis lesions, and 6 (6% [95% CI 2.2-12.6]) had adenomyosis. At follow-up, women with endometriosis or adenomyosis lesions reported lower intensity of dysmenorrhea and chronic pelvic pain compared to women without lesions (48 mm [IQR 16-79] vs. 73 mm [IQR 46-85] and 45 mm [IQR 26-57] vs. 57 mm [IQR 36-75], p = 0.087 and p = 0.026, respectively). None of the women with endometriosis or adenomyosis lesions reported increased intensity of dysmenorrhea at follow-up, compared to 32/86 women (37%) without lesions (p = 0.008). Increased intensity of chronic pelvic pain tended to be less common in women with lesions compared to those without (3/13 [23%] vs. 35/86 [41%], p = 0.223).

CONCLUSIONS

Our findings suggest that in symptomatic women, endometriosis and adenomyosis lesions visible at ultrasound may develop over time. However, majority of women remain having normal ultrasound examinations despite symptoms. Exacerbation of dysmenorrhea or chronic pelvic pain during follow-up was not associated with the development of endometriosis or adenomyosis lesions visible at ultrasound, suggesting that even women with less severe symptoms might benefit from a follow-up ultrasound when indicated.

Pain Severity and Depressive Symptoms in Endometriosis Patients: Mediation of Negative Body Awareness and Interoceptive Self-Regulation

Endometriosis-related pain may be associated with depressive symptoms. Although a growing body of evidence supports this association, the underlying mechanisms are still largely unclear. Impaired perceptions of bodily external and internal stimuli may be involved in this process. This study aims to assess the mediating role of 2 facets of interoception-the awareness of negative body signals and interoceptive self-regulation-in the association between pain severity and depressive symptoms among women with endometriosis. A total of 301 patients who reported a diagnosis of endometriosis were recruited from an endometriosis and chronic pelvic pain outpatient university clinic and through patient associations and completed self-reported instruments. A parallel mediation analysis was conducted. Almost half of women (48.2%) reported depressive symptoms above the self-rating scale cutoff values. Pain severity significantly predicted depressive symptoms (β = .39, 95% bootstrap confidence interval [CI] [.719, 1.333]). Negative body awareness (β = .121, 95% bootstrap CI [.174, .468]) and interoceptive self-regulation (β = .05, 95% bootstrap CI [.035, .252]) partially mediated this relationship. Our findings indicated that pain may interfere with the perception of the body as a source of calmness and safety, limiting the individual's ability to effectively regulate emotions. Future research should further explore these mechanisms and evaluate the efficacy of interventions focusing on interoceptive sensibility to enhance the psychological well-being of endometriosis patients. PERSPECTIVE: This article investigates for the first time the potential role of 2 facets of interoceptive sensibility in the relationship between pain severity and depressive symptoms in women with endometriosis. These findings may contribute to advancing knowledge about the mechanisms involved in the complex pain-depression cycle.

A systematic literature review on patient-reported outcome domains and measures in nonsurgical efficacy trials related to chronic pain associated with endometriosis: an urgent call to action

ABSTRACT

Endometriosis, a common cause for chronic pelvic pain, significantly affects quality of life, fertility, and overall productivity of those affected. Therapeutic options remain limited, and collating evidence on treatment efficacy is complicated. One reason could be the heterogeneity of assessed outcomes in nonsurgical clinical trials, impeding meaningful result comparisons. This systematic literature review examines outcome domains and patient-reported outcome measures (PROMs) used in clinical trials. Through comprehensive search of Embase, MEDLINE, and CENTRAL up until July 2022, we screened 1286 records, of which 191 were included in our analyses. Methodological quality (GRADE criteria), information about publication, patient population, and intervention were assessed, and domains as well as PROMs were extracted and analyzed. In accordance with IMMPACT domain framework, the domain pain was assessed in almost all studies (98.4%), followed by adverse events (73.8%). By contrast, assessment of physical functioning (29.8%), improvement and satisfaction (14.1%), and emotional functioning (6.8%) occurred less frequently. Studies of a better methodological quality tended to use more different domains. Nevertheless, combinations of more than 2 domains were rare, failing to comprehensively capture the bio-psycho-social aspects of endometriosis-associated pain. The PROMs used showed an even broader heterogeneity across all studies. Our findings underscore the large heterogeneity of assessed domains and PROMs in clinical pain-related endometriosis trials. This highlights the urgent need for a standardized approach to both, assessed domains and high-quality PROMs ideally realized through development and implementation of a core outcome set, encompassing the most pivotal domains and PROMs for both, stakeholders and patients.

Ultrasonographic characterization of parametrial endometriosis: a prospective study

OBJECTIVE

To study the ultrasonographic diagnostic accuracy and characteristics of parametrial endometriosis comprehensively.

DESIGN

This prospective study enrolled patients with suspected deep endometriosis (DE) scheduled for laparoscopic surgical treatment. Preoperative ultrasonographic examinations were performed following the International Deep Endometriosis Analysis criteria. This study aimed to evaluate the presence of parametrial endometriosis and its ultrasonographic characteristics, using surgical diagnosis as the reference standard. Additionally, indirect signs of DE and concomitant DE nodules associated with parametrial involvement were identified, assessing their predictive significance in the anterior, lateral, and posterior parametrial areas.

SETTING

Referral institution for endometriosis.

PATIENTS

Patients with suspected DE scheduled for surgical treatment.

INTERVENTIONS

Standardized preoperative ultrasonographic examination.

MAIN OUTCOME MEASURES

The diagnostic accuracy of transvaginal ultrasound in identifying parametrial endometriosis, including sensitivity and specificity, and the ultrasonographic characteristics of parametrial nodules, prevalence in distinct parametrial areas, and associations with indirect DE signs and concomitant DE nodules.

RESULTS

Surgical confirmation of parametrial nodules was observed in 105 of 545 patients (left, 18.5; right, 17.0%). Transvaginal ultrasound demonstrated a sensitivity of 77.1% (95% confidence interval, 68.0%-84.8%) and specificity of 99.1% (95% confidence interval, 67.7%-99.8%). Parametrial nodules typically exhibited characteristics such as a mild hypoechoic appearance (83.6%), starry morphology (74.7%), irregular margins (70.2%), and low vascularization. The posterior parametrial region was the most common location (52.2%), followed by the lateral (41.0%) and anterior (6.8%) parametrial regions. Concomitant DE nodules in the rectum (63.5%) and infiltrating the rectovaginal septum (56.5%) were significantly more prevalent in patients with parametrial involvement. Indirect DE signs, such as the ovaries fixed to the uterine wall (71.8%) and the absence of a posterior sliding sign (51.8%), were also more common in women with parametrial nodules. Hydronephrosis, although relatively uncommon in patients with parametrial involvement (8.2%), was largely detected in lateral parametrial nodules (70.0%).

CONCLUSIONS

This study represents a systematic ultrasonographic characterization of parametrial endometriosis. Specifically, it comprehensively assesses the diagnostic accuracy of transvaginal ultrasound in identifying parametrial involvement within a sizable cohort of patients with preoperative suspicion of DE.

Screening women in young adulthood for disabling dysmenorrhoea: a nationwide cross-sectional study from the CONSTANCES cohort

RESEARCH QUESTION

How do different warning indicators help to identify disabling dysmenorrhoea among women in young adulthood?

DESIGN

A nationwide cross-sectional study of women aged 18-25 years from the CONSTANCES cohort was constructed. Disability was assessed with the Global Activity Limitation Indicator question 'For the past 6 months, have you been limited in routine activities?Yes, severely limited/Yes, limited/ No, not limited'. Dysmenorrhoea pain intensity and other chronic pelvic pain symptoms (dyspareunia and non-menstrual pain) were evaluated according to questions from a specific questionnaire. Probability of disability was estimated using a logistic prediction model according to dysmenorrhoea intensity, other indicators of pelvic pain symptoms and other obvious covariates. The results of the predictive model of disabling dysmenorrhoea were presented on a nomogram.

RESULTS

Among 6377 women, the rate of disability was estimated at 7.5%. Increased intensity of dysmenorrhoea (odds ratio [OR] 1.08, 95% confidence interval [CI] 1.04-1.13), increased frequency of dyspareunia (from OR 1.69, 95% CI 1.33-2.14 up to OR 3.41, 95% CI 2.16-5.38) non-menstrual chronic pelvic pain (OR 1.75, 95% CI 1.40-2.19), body mass index over 25 kg/m2 (OR 1.45, 95% CI 1.17-1.80) and non-use of the hormonal contraceptive pill (OR 1.29, 95% CI 1.05-1.59) were significantly associated with disability. According to the nomogram, a predicted probability of 15% or more could be chosen as a threshold. This represents almost 4.6% of young women in this sample being classified at risk of disabling dysmenorrhoea.

CONCLUSIONS

Dysmenorrhoea pain intensity and associated pelvic pain symptoms are warning indicators that can be measured to help screen young women who may suffer from disabling dysmenorrhoea.

Evaluating the efficacy and safety of perianal injection of liposomal ropivacaine HR18034 for postoperative analgesia following hemorrhoidectomy: A multicenter, randomized, double-blind, controlled phase II clinical trial

STUDY OBJECTIVE

HR18034, composed of the ropivacaine encapsulated in multi-lamellar, concentric circular structure liposomes as the major component and a small amount of free ropivacaine, has performed well in animal experiments and phase I clinical trials. This trial was to investigate the efficacy, safety, pharmacokinetic profile and the minimum effective dose of HR18034 for postoperative analgesia after hemorrhoidectomy compared with ropivacaine.

DESIGN

A multicenter, randomized, double-blind trial.

SETTING

19 medical centers in China.

PATIENTS

85 patients undergoing hemorrhoidectomy between October 2022 to November 2022.

INTERVENTIONS

Patients were randomly divided into HR 18034 190 mg group, 285 mg group, 380 mg group and ropivacaine 75 mg group, receiving single local anesthetic perianal injection for postoperative analgesia.

MEASUREMENTS

The primary outcome was the area under the resting state NRS score -time curve within 72 h after injection. The second outcomes included the proportion of patients without pain, the proportion of patients not requiring rescue analgesia, cumulative morphine consumption for rescue analgesia, etc. Safety was evaluated by adverse events incidence and plasma ropivacaine concentrations were measured to explore the pharmacokinetic characteristics of HR18034.

MAIN RESULTS

The areas under the NRS score (at rest and moving states)-time curve were significantly lower in HR 18034 380 mg group than ropivacaine 75 mg at 24 h, 48 h, and 72 h after administration. However, this superiority was not observed in HR18034 190 mg group and 285 mg group. There was no difference in cumulative morphine consumption for rescue analgesia between HR 18034 groups and ropivacaine group.

CONCLUSIONS

HR 18034 380 mg showed superior analgesic efficacy and equivalent safety compared to ropivacaine 75 mg after hemorrhoidectomy, thus preliminarily determined as minimum effective dose.

The Need to Look at Transgender and Gender Diverse People's Health: A Preliminary Descriptive Report on Pain, Sexual Distress, and Health Profile of Five Transmasculine People and One Non-Binary Person with Endometriosis

The sexual health of transgender and gender diverse (TGD) people with endometriosis has been overlooked, and important emotional experiences, such as sexual distress and its correlates, have been ignored. This has prevented a more comprehensive look at the health experiences of TGD individuals. This descriptive online survey study preliminarily explored the experiences of pain symptoms, sexual distress, and mental health of N = 6 TGD individuals diagnosed with endometriosis. Descriptive results showed a mean delay of 10 years from the onset of symptoms to the diagnosis. Endometriosis-related pain was a common symptom, although with low to moderate intensity. Results also showed higher mean levels of pain impact, powerlessness and lack of control, somatization, depression, anxiety, and sexual distress, and lower mean levels of emotional well-being, social support, and worse self-image compared to reports on cisgender women with endometriosis in the literature. These results suggested that sexual and mental health in the context of TGD people with endometriosis has specificities and may be associated with factors that need to be accounted for to provide comprehensive and socially just healthcare, such as the recognition of the impact of endometriosis treatment on symptoms of gender dysphoria. To achieve sexual health equity for TGD people, continuous and updated professional training and inclusive research with multiple informants are necessary.

Characteristics and predictors of pain among women who underwent cesarean section in Fiji

Aim: To identify the characteristics and predictors of post cesarean section (CS) pain among women.Materials & methods: This quantitative study was conducted at Labasa hospital in Fiji over a 6-month period. A total of 312 mothers who received spinal, epidural and general anesthesia were included. Their pain score was assessed using the visual analogue scale 24 h postoperatively.Results: 70.8% women had either moderate or severe pain on the visual analogue scale. About 41.3% women expressed dissatisfaction with their pain management and 70.5% women had difficulties in performing activities due to pain. Lower parity was noted to be a positive predictor of pain among women undergoing CS.Conclusion: Adequate pain management for post-CS patient at Labasa hospital is lacking.

Do we want to know the enormity of women's severe menstrual disorders and chronic pelvic pain?

OBJECTIVE

The purpose of this paper is to call for a nationwide study to assess the prevalence and incidence of women health problems related to menstrual disorders and severe pelvic pain.

RATIONALE

The exact prevalence and incidence of endometriosis, adenomyosis, severe painful menstrual disorders, and of severe chronic pelvic pain are unknown. These issues severely impact women's quality of life and represent huge costs for our societies. Using adapted questionnaires, recent progresses in diagnosis and increased fundings announced by politicians, we can and should change this situation by performing a nationwide study to assess prevalence and incidence of these women problems in the French general population. The huge, anticipated costs of this study do appear quite reasonable when accounting for the enormous costs and societal consequences of endometriosis, menstrual disorders and severe pelvic pain.

CONCLUSION

These long-awaited data will improve our understanding of the causes, consequences, and natural history of endometriosis. These data will allow women to better understand that pain is not always related to endometriosis, thus preventing unjustified fears. Physicians will be able to adapt and improve medical managements, particularly the diagnosis. Politicians will have the tools to improve women's health and gender equality.

Using language to identify a bladder pain component in women with Dysmenorrhoea-Related Pelvic Pain: A cross-sectional study

BACKGROUND

Dysmenorrhoea-Related Pelvic Pain (DRPP) is a common condition, which may or may not include bladder-related symptoms. Primary health care practitioners (PHCP) rely heavily on language for diagnosis of DRPP-related conditions. However, there are no established pain descriptors to assist PHCP to determine whether an individual's DRPP may include a bladder component.

AIMS

To identify differences in the use of pain descriptors in women with DRPP with and without a co-existing bladder pain component, through an exploratory study of the language of pelvic pain in women.

MATERIALS AND METHODS

A cross-sectional online survey of Australian and New Zealand women (n = 750, ages 18-49) who have self-identified pelvic pain. Free text and predetermined pain descriptors used by women with a self-perceived bladder pain component (DRPPB+, n = 468) were compared to those without bladder pain (DRPPB-, n = 282). Statistical analysis included Pearson χ2, logistic regression and analysis of variance tests using StataCorp Stata Statistical Software combined with qualitative data from AntConc concordance software.

RESULTS

Within free-form text, bloating (P = 0.014) and pressure (P = 0.031) were used more commonly to describe dysmenorrhoea in women with DRPPB+, while the word excruciating (P < 0.001) was more commonly used by women with DRPPB-. From a pre-determined list of descriptors, pounding (P < 0.001), tingling (P < 0.001), stabbing (P = 0.010), burning (P = 0.002) and cramping (P = 0.021) were more commonly used by women with DRPPB+, than women with DRPPB-.

CONCLUSIONS

Systematic patterns of word use should encourage practitioners to further enquire about bladder symptoms that may co-exist with dysmenorrhoea. Knowledge of these words may be useful in targeting diagnostic and therapeutic interventions.

FEMaLe: The use of machine learning for early diagnosis of endometriosis based on patient self-reported data-Study protocol of a multicenter trial

INTRODUCTION

Endometriosis is a chronic disease that affects up to 190 million women and those assigned female at birth and remains unresolved mainly in terms of etiology and optimal therapy. It is defined by the presence of endometrium-like tissue outside the uterine cavity and is commonly associated with chronic pelvic pain, infertility, and decreased quality of life. Despite the availability of various screening methods (e.g., biomarkers, genomic analysis, imaging techniques) intended to replace the need for invasive surgery, the time to diagnosis remains in the range of 4 to 11 years.

AIMS

This study aims to create a large prospective data bank using the Lucy mobile health application (Lucy app) and analyze patient profiles and structured clinical data. In addition, we will investigate the association of removed or restricted dietary components with quality of life, pain, and central pain sensitization.

METHODS

A baseline and a longitudinal questionnaire in the Lucy app collects real-world, self-reported information on symptoms of endometriosis, socio-demographics, mental and physical health, economic factors, nutritional, and other lifestyle factors. 5,000 women with confirmed endometriosis and 5,000 women without diagnosed endometriosis in a control group will be enrolled and followed up for one year. With this information, any connections between recorded symptoms and endometriosis will be analyzed using machine learning.

CONCLUSIONS

We aim to develop a phenotypic description of women with endometriosis by linking the collected data with existing registry-based information on endometriosis diagnosis, healthcare utilization, and big data approach. This may help to achieve earlier detection of endometriosis with pelvic pain and significantly reduce the current diagnostic delay. Additionally, we may identify dietary components that worsen the quality of life and pain in women with endometriosis, upon which we can create real-world data-based nutritional recommendations.

Correlation Between Surgical Phenotype and Pain Improvement After Endometriosis Surgery

STUDY OBJECTIVE

To examine pain improvement after endometriosis surgery and whether it can be predicted by the observed surgical phenotype.

DESIGN

Prospective longitudinal survey study.

SETTING

A University hospital.

PATIENTS

A total of 125 patients completed a preoperative questionnaire (response rate: n = 227 of 277, 81.9%), had surgically confirmed endometriosis (n = 202 of 227), and returned a second postoperative questionnaire (response rate: n = 125 of 202, 61.9%).

INTERVENTIONS

All patients underwent complete laparoscopic removal of the endometriotic lesions. Surgical phenotype was classified according to the rASRM and #Enzian classification.

MEASUREMENTS AND MAIN RESULTS

The intensity of 5 specific pain symptoms was questioned by postal paper-pencil questionnaires with a numerical rating scale (0-10) both preoperatively (3.01 ± 2.72 months before surgery) and one year after surgery (12.62 ± 1.59 months). A postoperative pain improvement score was computed (postoperative pain-preoperative pain) for each specific pain symptom (0-10) and for the overall/global pain sum score (0-50). The mean intensity of all pain scores was lower postoperatively as compared with preoperatively (p <.0001). A statistically significant weak correlation was observed between the surgical phenotype "rectovaginal endometriosis" and postoperative improvement of dyspareunia (r = .265; p = .003). The other 11 hypothesized correlations between surgical phenotype and postoperative improvement of pain intensity failed to reach statistical significance.

CONCLUSION

Clinicians can inform patients that surgery is effective in reducing endometriosis-related pain symptoms and the overall/global pain scores at 12 months postoperatively. From our data, we can conclude that patients with rectovaginal endometriosis might benefit the most from the reduction of their sexual pain. On the basis of these results, we could suggest that deep dyspareunia (even if present as an isolated symptom) might be a valid indication for surgery. Further research could explore the association between a certain surgical phenotype and more detailed assessments of sexual functioning, as well as explore whether feedback from the surgeon on expected pain improvement affects patient-reported outcomes.

Long-term effects of surgically corrected menstrual outflow obstruction: A case-control study

OBJECTIVE

To enhance evidence-based knowledge on long-term sequalae in patients with surgically corrected obstructing Müllerian anomalies.

METHODS

This long-term case-control study included patients with menstrual outflow obstruction due to congenital anomalies of the uterus or vagina, who were at least 18 years old, and for whom 2 years had elapsed since the first surgery at the start of this study. The control group consisted of women without current gynecological problems. Patients underwent a surgical correction at the Radboud University Medical Center Nijmegen between 1980 and 2013. Of 78 patients approached, 38 (49%) were included in this study. The control group consisted of 54 females. The main outcome measures were pain and health state. The following questionnaires were used: Visual Analogue Scale pain scores, European Quality of Life-5 Dimensions questionnaire (EQ-5D-3L) and the adapted Endometriosis Health Profile questionnaire (EHP-30).

RESULTS

Patients had higher actual and maximum abdominal pain scores compared with controls (11 vs 0 [P = 0.007] and 48 vs 21 [P = 0.035], respectively). Based on the EQ-5D-3L scores, patients had more pain and discomfort (P = 0.005), more mood problems (P = 0.023), and a poorer subjective health state (P = 0.002) and self-rated health state (P = 0.031). Based on the EHP-30, patients had a significant poorer self-rated health state on four out of five subscales.

CONCLUSION

In this study, following surgically corrected menstrual obstruction, patients had statistically significant higher abdominal pain scores and a poorer self-rated health state compared with controls.

Psychological distress and pain related to gynecologic exams among female survivors of sexual and physical violence: A systematic review

Gender-based violence is prevalent globally, yet the impacts of sexual and physical violence on women's experiences of routine gynecologic care are not well understood. The purpose of this systematic review of quantitative research is to describe (a) psychological distress and pain related to gynecologic exams among female survivors of sexual and physical violence and (b) differences in distress or pain between survivors and women without this history. Fourteen articles based on 12 discrete studies met the inclusion criteria. Studies were heterogeneous, with a moderate risk of bias; therefore, a descriptive summary approach was utilized rather than a meta-analytic approach. Synthesized results indicated that survivors of violence experience mild-to-severe levels of distress and mild-to-moderate levels of pain related to gynecologic exams. The findings suggest that survivors of sexual or physical violence experience higher levels of distress than women without this history (i.e., moderate to severe), and this difference was further accentuated among women with more severe posttraumatic stress symptoms (PTSS). Differences in pain by violence history and PTSS severity were not consistently observed, possibly due to a lack of variability in ratings and small sample sizes. Additional research is needed that bolsters the measurement of exam-related distress and pain, adjusts for confounding variables, and explores mechanisms by which sexual and physical violence impact care experiences. Further empirical work will be critical to developing interventions at the patient and provider levels to improve women's experiences of care.

Visual Analogue Scale Cut-off Point of Seven Represents Poor Quality of Life in Patients with Endometriosis

Establishing objective criteria to assess endometriosis symptoms is crucial in defining therapeutic strategies. The visual analogue scale (VAS) is the most used system to enhance the accuracy and reduce the subjectivity of pain assessment, and symptoms of endometriosis are considered severe when the VAS score is ≥ 7 cm. Pain symptoms can significantly impact patients' quality of life, resulting in psychological and social distress. The aim of this study is to evaluate whether a VAS cut-off point of 7 cm for each pain symptom correlates with a diminished quality of life in women with endometriosis. This retrospective study included 1129 patients who underwent surgical treatment for endometriosis. Dysmenorrhea, acyclic pelvic pain, deep dyspareunia, dyschezia, and dysuria were assessed using a 0-10 cm VAS. The Short Form-36 (SF-36) questionnaire was employed to evaluate the quality of life 6 months prior to surgery. Dysmenorrhea was the most prevalent symptom reported in 93.6% of cases, with a mean VAS of 7.6 cm. The quality of life reported was reduced in most patients, with domain scores ranging from 49.4 to 80.1. The mean SF-36 scores in all domains were significantly lower in patients with severe pain (VAS score ≥ 7 cm) compared to those with mild to moderate pain (VAS < 7 cm). This trend was observed across all evaluated pain symptoms. Our research demonstrates that the prevalent VAS cut-off point for establishing severe pain symptoms in endometriosis (VAS ≥ 7 cm) accurately represents the negative impact of the disease on women's quality of life, as assessed via the SF-36 questionnaire.

Robotic surgery for deep-infiltrating endometriosis: is it time to take a step forward?

Endometriosis is a chronic debilitating disease that affects nearly 10% of women of the reproductive age. Although the treatment modalities of endometriosis are numerous, surgical excision of the endometriotic implants and nodules remains the sole cytoreductive approach. Laparoscopic excision of endometriosis was proven to be beneficial in improving the postoperative pain and fertility. Moreover, it was also proved to be safe and efficient in treating the visceral localization of deep endometriosis, such as urinary and colorectal endometriosis. More recently, robotic-assisted surgery gained attention in the field of endometriosis surgery. Although the robotic technology provides a 3D vision of the surgical field and 7-degree of freedom motion, the safety, efficacy, and cost-effectiveness of this approach are yet to be determined. With this paper, we aim to review the available evidence regarding the role of robotic surgery in the management of endometriosis along with the current practices in the field.

Questionnaires for the Assessment of Central Sensitization in Endometriosis: What Is the Available Evidence? A Systematic Review with a Narrative Synthesis

It has been suggested that central sensitization (CS) may be involved in the failure of standard medical and surgical treatment to relieve endometriosis-related pain. However, there is no gold standard for the diagnosis of CS, and self-reported questionnaires are used as diagnostic surrogates. The main objective of this review was to identify all CS questionnaires used in clinical endometriosis studies. The secondary objective was to qualitatively analyze strengths and weaknesses of each questionnaire. A PubMed and EMBASE systematic literature search conducted in April 2023 using the terms "endometriosis; central pain; central sensitization; questionnaire; patient-reported outcome measure; screening tool" identified 122 publications: six articles were included in the review. The Central Sensitization Inventory (CSI) is the most frequently used questionnaire for the detection of CS in patients with endometriosis. It has been validated in patients with endometriosis, in whom it appears to have good psychometric proprieties. The Fibromyalgia Survey Questionnaire (FSQ) has also been used, although it has not been specifically validated in endometriosis patients. The debate regarding these questionnaires' construct validity is still open and will be so until a gold standard diagnostic tool for CS is found. In fact, some authors argue these questionnaires are measuring psychological vulnerability and a hypervigilant state that is associated with pain, rather than CS itself. However, their use should not be discouraged as they are able to identify chronic pain patients which warrant further attention and who may benefit from broader treatment strategies.

Horizontal versus vertical direction of posterior vaginal wall suture after eradication of rectovaginal endometriosis: A multicenter study

OBJECTIVE

To compare safety and effectiveness of two-different directions of suturing the posterior vaginal breach (horizontal [Ho] vs vertical [Ve]) in women undergoing recto-vaginal endometriosis (RVE) nodule resection.

METHODS

A multicenter, retrospective, observational, cohort study was performed including all women of reproductive age undergoing RVE nodule resection between March 2013 and December 2018 at our tertiary centers. Patients included in the present study were divided into two groups based on the direction in suturing the posterior vaginal fornix defect, for comparisons in terms of rate of postoperative complications, pain relief, pain and anatomical recurrence, and length of hospital stay. Univariate comparisons were performed adopting the t test or the Mann-Whitney test for continuous data and the chi-square test or the Fisher exact test for categorical data, with a significant P value set to <0.05.

RESULTS

A total of 101 women were included: 67 in the Ho-group and 34 in the Ve-group. The two groups did not significantly differ in length of hospital stay (6.7 ± 6.9 vs 6.6 ± 3.3 days; P = 0.95), overall postoperative complications (32.8% vs 14.7%; P = 0.05), pain recurrence (35.8% vs 26.5%; P = 0.34) and anatomical recurrence rate (19.4% vs 23.5%; P = 0.62). Conversely, grade III complications were significantly more common in the Ho-group than in the Ve-group (22.7% vs 20%, P = 0.009), while pain relief in terms of deep dyspareunia, dyschezia, dysuria and chronic pelvic pain was more consistent in the Ve-group patients (P = 0.04, 0.04, 0.05, 0.004, respectively).

CONCLUSION

In symptomatic women undergoing RVE nodule resection, Ho suturing of the vaginal breach appears more commonly associated with severe postoperative complications and a worse pain control.

Do women with suspected endometriosis benefit from pelvic examination to improve diagnostic and management strategy?

OBJECTIVE

To analyze the literature and expose best evidence available regarding the benefit of pelvic examination for women with suspected endometriosis METHODS: the AGREE II and GRADE systems for grading scientific evidence.

RESULTS

Endometriosis is characterized by the heterogeneity in its clinical presentation with many different symptoms reported by patients. In the literature, questioning for each symptom has a high sensitivity, reaching 76-98 %, but lacks specificity (20 - 58 %). The symptom-based approach is limited by its low specificity, the absence of external validation for most of the models developed and the inability to characterize the extent of the disease, which could have major implications in the decision - making process. The latest systematic review and meta-analysis included a total of 30 studies with 4,565 participants, compared the diagnostic performance of several modalities for endometriosis. Physical examination had a pooled sensitivity of 71 % and a specificity of 69 %, with an average diagnostic accuracy of 0.76. Overall, the value of pelvic examination is conferred by its high positive likehood ratio and specificity. Besides its diagnostic value, pelvic examination improves patients' management by allowing the identification of a possible myofascial syndrome as a differential diagnosis. It also increases the quality of the preoperative workup and influences the quality of surgical excision and decreases the time to diagnosis.

CONCLUSION

Despite the lack of studies in the primary care context, pelvic examination (vaginal speculum and digital vaginal examination) increases the diagnostic value for suspected endometriosis in association with questioning for symptoms.

Patient-Reported Outcome Measures Used in Randomized Controlled Trials Following Surgical Intervention for Endometriosis: A Structured Review from the AAGL Practice Guidelines Group

OBJECTIVE

No consensus currently exists regarding patient-reported outcome measure (PROM) instruments. This structured review was conducted to identify the PROMs used by randomized controlled trials (RCTs) that evaluated surgical treatment in patients with endometriosis.

DATA SOURCES

Two parallel searches were conducted by a medical librarian using Ovid MEDLINE, Ovid Embase, and Cochrane Library for RCTs published from 2000 to July 2022. One search focused on studies reporting quality of life (QoL), and the second search focused on studies reporting pain and sexual, bowel, and bladder function.

METHOD OF STUDY SELECTION

During the title and abstract screening and reference check, 600 results were identified on PROMs relating to QoL and 465 studies on PROMs relating to pain and sexual, bowel, and/or bladder function and an evaluation of 17 and 12 studies conducted, respectively. The inclusion criteria involved selecting RCTs that focused on surgical intervention and assessing QoL, pain, and sexual, bowel, and/or bladder function using PROMs.

TABULATION, INTEGRATION, AND RESULTS

Covidence software was used to organize and identify duplicate articles through screening. We developed a data extraction form to collect key information about each included study, as well as the pertinent PROMs used in the study. Assessment of the risk of bias of each study was also performed. A total of 19 studies were identified involving 2089 participants and a total of 16 PROMs used across the studies; 9 of 19 studies (47%) were rated as having a low risk of bias. There were no high-risk studies identified in this review.

CONCLUSION

This study identified a large number of RCTs in surgical treatment of endometriosis that used various PROMs to assess QoL, pain, and bladder, bowel, and sexual function. The PROMs used by high-quality RCTs for QoL include Endometriosis Health Profile-30, Endometriosis Health Profile-5, Short-Form 36, Short-Form 12, and EQ-5D; for bowel-related symptoms Knowles-Eccersley-Scott-Symptom Questionnaire, Gastrointestinal Quality of Life Index, and Cleveland Clinic Fecal Incontinence Severity Scoring System/Wexner; for bladder-related function Bristol Female Lower Urinary Tract Symptoms, International Prostate Symptom Score, Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire, and Urinary Symptom Profile; and finally for sexual function Pelvic Organ Prolapse/Urinary Incontinence Sexual Function Questionnaire and Sexual Activity Questionnaire. Unlike other domains, only one tool (visual analog scale) was the dominant PROM used for the assessment of pain. In addition, the use of more than one PROM in each study to assess different aspects of patient's health and pain symptoms did not become prevalent until after 2015.

Efficacy and safety of a novel pain management device, AT-04, for endometriosis-related pain: study protocol for a phase III randomized controlled trial

BACKGROUND

Endometriosis-related pain encompassing dysmenorrhea, dyspareunia, and chronic pelvic pain, reduces the quality of life in premenopausal women. Although treatment options for endometriosis alleviate this pain, approximately one-third of women still experience pain even after receiving treatment, indicating the need for novel approaches to pain relief in those women. The Angel Touch device (AT-04) is a portable magnetic fields irradiation device that incorporates a combination of mixed alternative magnetic fields at 2 kHz and 83.3 MHz. A phase III trial confirmed the efficacy and safety of AT-02, a prototype of AT-04, for pain relief in patients with fibromyalgia.

METHODS

This is a phase III, multicenter, prospective, randomized, sham device-controlled, double-blind, parallel study. The participants will be premenopausal women aged > 18 years who have endometriosis-related pain with at least moderate severity. Considering dropouts, 50 participants have been deemed appropriate. Eligible women will be centrally registered, and the data center will randomly allocate them in a 1:1 ratio to the intervention and control groups. Women in the intervention group will receive electromagnetic wave irradiation generated by AT-04 and those who in the control group will wear a sham device for 16 weeks, and both groups will wear AT-04 for another 4 weeks. The primary outcome measure is the change in the Numeric Rating Scale score at 16 weeks compared with the baseline. Secondary outcome measures are efficacy for pelvic pain including dysmenorrhea and non-menstrual pain, and chronic pelvic pain not related to menstruation, dysmenorrhea, and dyspareunia, and improvement of quality of life during the study period. Safety will be evaluated by device defects and the frequency of adverse events. The study protocol has been approved by the Clinical Study Review Board of Chiba University Hospital, Chiba, Japan, and will be conducted in accordance with the principles of the Declaration of Helsinki and the Japanese Clinical Trials Act and relevant notifications.

DISCUSSION

This study aims to develop a novel method of managing endometriosis-related pain. The AT-04 is an ultralow-invasive device that can be used without inhibiting ovulation, suggesting potential benefits to women of reproductive-age. Trial registration number Japan Registry of Clinical Trials (jRCTs032230278).

Feasibility and Effectiveness of Hysteroscopic Suture Fixation of the Levonorgestrel-Releasing Intrauterine System in the Treatment of Adenomyosis

STUDY OBJECTIVE

To evaluate the feasibility and effectiveness of hysteroscopic suture fixation of the levonorgestrel-releasing intrauterine system (LNG-IUS) for the treatment of adenomyosis.

DESIGN

A retrospective case series.

SETTING

Two teaching hospitals with the technology of hysteroscopic suture fixation of the LNG-IUS.

PATIENTS

The study reviewed 79 adenomyosis patients who received the hysteroscopic suture fixation of the LNG-IUS from January 2021 to May 2022.

INTERVENTION

Hysteroscopic suture fixation of the LNG-IUS to the posterior uterine wall with nondissolvable suture.

MEASUREMENTS AND MAIN RESULTS

All patients underwent one-year postoperative follow-up to evaluate the LNG-IUS expulsion rate, postoperative efficacy, and side effects. Two patients (2.6%) experienced expulsion of the LNG-IUS at 8 months and 12 months postoperatively, respectively. The visual analog pain scale, pictorial blood loss assessment chart score and carbohydrate antigen 125 markedly decreased after the suture fixation of the LNG-IUS compared with baseline in all patients (p <.001). Hemoglobin increased significantly (p <.001). The most common side effect was irregular bleeding, which accounted for 44.3%. The second common side effect was weight gain, which accounted for 29.2%. The composite effectiveness based on pain and bleeding showed that the effective treatment rates at 1, 3, 6, and 12 months after surgery were 92.4%, 97.4%, 96.2%, and 97.4% respectively.

CONCLUSIONS

Hysteroscopic suture fixation of the LNG-IUS to the uterine fundus was associated with low expulsion rates and significantly improved dysmenorrhea and bleeding.

Effects of Pelvic Floor Muscle Physiotherapy on Urinary, Bowel, and Sexual Functions in Women with Deep Infiltrating Endometriosis: A Randomized Controlled Trial

Background and Objectives: Endometriosis is a chronic and recurrent disease defined as the presence and proliferation of endometrial glands and stroma outside the uterine cavity. It affects up to 6-10% of women of reproductive age and can be classified into superficial, ovarian, and deep infiltrating endometriosis (DIE). Deep infiltrating endometriosis can be associated with pain symptoms and pelvic floor muscle hypertone. Moreover, it may be responsible of bowel, urinary, and sexual dysfunctions with impairment of women's quality of life. Few studies have investigated the role of physiotherapy in women with DIE. Here, we aimed first to evaluate the effects of pelvic floor physiotherapy (PFP) on urinary, bowel, and sexual functions. Secondly, we aimed to evaluate the effects of ultrasound visual feedback during PFP on pelvic floor and subjective modifications in the frequency of sexual intercourse. Materials and Methods: This randomized controlled trial was conducted between June 2018 and December 2019 at our tertiary center. Nulliparous women with DIE and superficial dyspareunia were enrolled. At first examination, levator hiatal area (LHA) assessed with 3D/4D transperineal ultrasound, pain symptoms, urinary, bowel, and sexual functions were evaluated. Then, women were randomly assigned to no intervention (control group) or treatment with five individual sessions of PFP (experimental group), and after four months women underwent a second examination. Urinary, bowel, and sexual functions were assessed with validated questionnaires at first and second examinations. In particular, the Bristol Female Lower Urinary Tract Symptoms questionnaire was used to evaluate urinary symptoms, the Knowles-Eccersley-Scott-Symptom questionnaire to assess the presence of constipation, and the Female Sexual Function Index to investigate sexual function. Study outcomes were the comparisons among groups in terms of differences in actual changes in median of questionnaire scores between first and second examinations. Results: Thirty women (17 in the experimental group and 13 in the control group) completed the study. No significant differences were found between the two groups regarding urinary, bowel, and sexual functions, although women in the experimental group showed a tendency towards an improvement in constipation symptoms. Conclusion: In women with DIE, PFP does not appear to affect urinary, bowel, and sexual functions. Therefore, despite the improvement in superficial dyspareunia, chronic pelvic pain, and PFM relaxation with high treatment satisfaction, women should be informed about the unclear impact of PFP on urinary, bowel, and sexual functions. Larger studies are necessary to further investigate the impact of PFP on these functions.

IL-8 and IL-12p70 are associated with pelvic pain among infertile women with endometriosis

OBJECTIVE

To evaluate interleukin (IL)-1β, IL-6, IL-8, and IL-12p70 levels in serum and peritoneal fluid in women related to infertility and pelvic pain.

METHODS

Eighty-seven women were diagnosed with endometriosis or cases related to infertility. IL-1β, IL-6, IL-8, and IL-12p70 levels in serum and peritoneal fluid were determined by enzyme-linked immunosorbent assay (ELISA). Pain assessment was evaluated by the Visual Analog Scale (VAS) score.

RESULTS

Serum IL-6 and IL-12p70 levels increased in women with endometriosis compared to the control group. Serum and peritoneal IL-8 and IL-12p70 levels correlated with VAS scores in infertile women. A positive correlation was also found between peritoneal IL-1β and IL-6 with VAS score. A significant difference in peritoneal IL-1β levels was associated with menstrual pelvic pain, while peritoneal IL-8 levels were related to dyspareunia, menstrual, and post-menstrual pelvic pain in infertile women.

CONCLUSIONS

An association of IL-8 and IL-12p70 levels were related to pain in endometriosis, as well as a relationship between cytokine expression and VAS score. Further studies should be addressed to investigate the precise mechanism of cytokine-related pain in endometriosis.

Pain assessment in women with or without endometriosis during the IVF process: a prospective study

RESEARCH QUESTION

How does the typology and effect of pain vary between infertile patients with or without endometriosis during the different stages of the IVF process?

DESIGN

A prospective, monocentric, observational cohort study was conducted at Lille University Hospital between November 2019 and June 2021. The study was proposed to all patients starting an IVF cycle. Pain assessment questionnaires using validated scales (about type of pain, without specific location), were completed by patients at key points during IVF: before starting treatment, at the end of stimulation and on the day of oocyte retrieval.

RESULTS

A total of 278 patients were analysed: 73 patients with endometriosis and 205 without. At the start of the IVF process, patients with endometriosis had higher pain scores than disease-free women (mean numerical scale score 3.47 versus 1.12 [P < 0.0001]) and 17.81% of patients with endometriosis had neuropathic pain. For mental disorders before starting treatment, 22% of patients with endometriosis had suspected or confirmed depression, and 33% had anxiety compared with 8% and 20% in patients without endometriosis, respectively. During IVF, for patients without endometriosis, pain increased significantly between the baseline, the end of stimulation and on the day of retrieval (P ≤ 0.05). In patients with endometriosis, however, pain did not significantly vary during these times.

CONCLUSION

Endometriosis is associated with higher pain scores, but no increase in pain was observed during IVF for these patients. It seems essential to screen and characterize pain phenotypes in all patients before starting treatment and during stimulation to improve pain management.

Efficacy of manual therapy and pelvic floor exercises for pain reduction in primary dysmenorrhea: A prospective observational study

BACKGROUND

Primary dysmenorrhea represents one of the most common causes of pelvic and low back pain. Pharmacological treatment can present some side effects, and non-pharmacological treatments should be considered to improve the symptoms of primary dysmenorrhea. The aim of this study was to evaluate the efficacy of manual therapy (MT), pelvic floor exercises (PFE), and their combination (MT + PFE) to improve clinical outcomes and pain sensitivity in women with primary dysmenorrhea.

METHODS

A prospective observational study was conducted. Thirty females (age 25.0 ± 6.1 y) with history of primary dysmenorrhea participated to 8 sessions of 60 min of either MT, PFE or MT + PFE, twice per week. They participated to the different treatments according to the different services offered by the school of physiotherapy. A 0-10 numeric rating scale (NRS) was administered to assess subjective pain, while short-form 36 (SF-36) was used to evaluate quality of life. The pressure pain threshold (PPT) was assessed with a portable algometer on different pelvic and lumbar areas.

RESULTS

Independently from the treatment, significant improvements were reported for general pain NRS (p < 0.001; pη2 = 0.511), as well as most the domains of the SF-36, although the general health domain did not reach statistical significance (p = 0.613; pη2 = 0.010). PPT revealed a general improvement in all tested body areas, although on the quadratus lumborum, the PFE treatment did not induce a significant improvement compared to the MT and MT + PFE protocols (p = 0.039).

CONCLUSIONS

These findings highlight the importance of proposing physiotherapy treatments to females with primary dysmenorrhea to improve symptoms, with manual therapy combined with active pelvic floor exercise providing the best outcomes including an improvement of lumbar pain thresholds.

The temporal effect of emotional distress on psychological and physical functioning in endometriosis: A 12-month prospective study

Psychological factors of emotional distress and cognition have an important role in the understanding and management of endometriosis; however, their temporal relationship with key pain variables is not fully understood. This exploratory study sought to establish the temporal relationship between psychological and pain-related factors in a 12-month prospective study of 208 Australian women with endometriosis. Participants, aged 18-50 years and living in Australia, were recruited via social media and completed baseline (May 2019) and 12-month follow-up (June 2020) surveys. Participants who reported a diagnosis of endometriosis and menses in the past 12 months were included in the study. Structural equation modelling was used to determine the temporal effects of psychological and pain-related factors in endometriosis. In a covariate-adjusted model, baseline emotional distress was the only variable to predict pain catastrophizing (β = .24, p < .01), functional pain disability (β = .16, p < .05) and concomitant emotional distress (β = .55, p < .001) 12 months later, adjusting for age and chronic illness. Women who exhibit symptoms of distress may be at risk of poorer psychological and physical function at 12 months. Further research is required to understand the impact of psychological management early in the disease course.

Risk factors for irreversible unilateral loss of renal function in patients with deep endometriosis

Deep endometriosis (DE) can be more aggressive than other types of endometriosis, and may even lead to irreversible severe complications such as complete unilateral loss of renal function. We aimed to describe the clinical and radiologic characteristics of DE patients diagnosed with irreversible unilateral loss of renal function due to unilateral ureteral stenosis and evaluate risk factors for developing this loss. This retrospective cohort study included 436 patients who underwent laparoscopic DE surgery. We evaluated two groups of patients according to preserved (Non-Renal Loss Group; n = 421) or irreversible unilateral damaged renal function (Renal Loss Group; n = 15). Preoperative epidemiologic variables, clinical characteristics, radiologic findings and surgical treatments of all the patients were collected. The Renal Loss Group had a higher infertility rate and a higher proportion of asymptomatic patients. The following radiological variables showed statistically significant differences between the two groups: mean endometrioma diameter, the presence of intestinal DE and negative sliding sign. Multivariate analysis showed that infertility, being asymptomatic, having intestinal DE or torus uterinus/uterosacral ligament DE and a negative sliding sign significantly increased the risk of loss of renal function. Therefore, among patients with these clinical and/or radiological variables, severe urinary tract obstruction should be specifically ruled out.

QS ENDO Pilot - A Study by the Stiftung Endometrioseforschung (SEF) on the Quality of Care Provided to Patients with Endometriosis in Certified Endometriosis Centers in the DACH Region

Introduction Endometriosis significantly reduces patients' quality of life and is additionally a burden on healthcare and social security systems. There are currently no quality indicators for the treatment of endometriosis. The care of patients with endometriosis must be considered inadequate. QS ENDO aims to record the quality of care available in the DACH region and to introduce quality indicators for the diagnosis and treatment of endometriosis as part of providing quality assurance in endometriosis care. The first phase, QS ENDO Real, recorded the reality of current care using a questionnaire. The second phase, QS ENDO Pilot, investigated the treatment of 435 patients who underwent surgical treatment within a defined one month period in certified endometriosis centers. Material and Methods An online tool was used to gather information about 9 points which covered both prior patient history and the process of clinical diagnosis. Surgery reports were reviewed to obtain information about the surgical approach, the investigated sites, findings of any histological examinations, the use of classification systems, and information about resection status. Results 85.3% of patients were asked all 4 questions about their prior medical history. All 5 diagnostic steps were carried out in 34.5% of patients. The 3 areas needed to describe potential sites of disease were recorded in 67.1% of patients. Samples for histological examination were taken in 84.1% of patients. The endometriosis stage was classified in 94.7% of surgeries. A combination of the rASRM and the ENZIAN classifications, which is needed for complex cases, was used in 46.1% of patients. Complete resection was achieved in 81.6% of surgical procedures. Conclusion For the first time, the quality of care in certified endometriosis centers has been recorded using QS ENDO Pilot. Despite the high certification standards, a substantial number of required indicators were omitted.

Self-Determined Sexual Motivation in Persons with Endometriosis and Their Partners: Dyadic Associations of Autonomous and Controlled Sexual Motivations with Sexual and Relational Well-Being and Pain

Endometriosis is a chronic pain condition characterized by the growth of endometrial-like tissue outside of the uterus. Affected individuals and their partners report consequences to sexual functioning, sexual satisfaction, and relationship quality. Previous studies in clinical and non-clinical samples have found that sexual motivation can support or detract from sexual functioning; however, similar investigations are lacking among couples with endometriosis. Informed by self-determination theory, associations between autonomous and controlled sexual motivations with sexual functioning, sexual satisfaction, and relationship satisfaction for persons with endometriosis and their partners, and pain in persons with endometriosis were investigated. Couples (n = 54) completed measures of sexual motivation, sexual functioning, sexual satisfaction, relationship satisfaction, and pain. When persons with endometriosis reported greater autonomous sexual motivation, they were more sexually and relationally satisfied. When persons with endometriosis reported higher controlled sexual motivation, their pain was more unpleasant, and they and their partners were less sexually satisfied. Finally, when partners reported greater controlled sexual motivation, both members of the couple reported significantly lower sexual functioning. While controlled sexual motivation may hinder sexual and relational well-being in couples with endometriosis, autonomous sexual motivation may support them. The findings may inform interventions to promote sexual and relational health in couples with endometriosis.

Patients with endometriosis may experience worse clinical manifestations and therapeutic outcomes during COVID-19 in western China- a case series comparative analysis

BACKGROUND

Endometriosis is a crippling, ongoing, chronic inflammatory condition. The management of these patients has been impacted by the current COVID-19 pandemic, which is still controversial. This study compared the clinical therapy outcomes and psychological scores between before and during- the epidemic.

METHOD

The data of patients who were diagnosed with endometriosis in the Department of Gynecology, Chongqing Traditional Chinese Medicine Hospital from January 2018 to December 2022 were collected. The patients were divided into pre- and intra-COVID groups. The treatment results and psychological status of the two groups were compared.

RESULTS

A total of 1022 patients with endometriosis were enrolled, with a mean age of 33.16 ± 9.81 years and a BMI of 23.90 ± 3.04 kg/m², of which 434 cases (434/1022, 42.5%) were in the pre-COVID group and 588 cases (588/1022, 57.5%) in the intra-COVID group. Both groups were well balanced for age, BMI, history of abdominopelvic surgery, family relationships, education level, and duration between initial diagnosis and admission. Compared to the Pre-COVID group, the intra-COVID group had a higher proportion of patients with chronic pelvic pain (297/434, 68.4% vs. 447/588, 76.0%, p = 0.007) and dysmenorrhea (249/434, 62.8% vs. 402/588, 70.0%, p < 0.001), more patients requiring surgery (93/434, 21.4% vs. 178/588, 30.3%, p = 0.002) and longer hospital stays (5.82 ± 2.24 days vs. 7.71 ± 2.15 days, p < 0.001). A total of 830 questionnaires were completed. In the Intra-COVID group, PHQ-2 (2 (2, 3) vs. 3 (2,4), p < 0.001), GAD-2 (2 (1, 2) vs. 3 (2, 3), p < 0.001), PHQ-4 (4 (3, 5) vs. 5 (4, 7), EHP-5 (20.26 ± 6.05 vs. 28.08 ± 7.95, p < 0.001) scores were higher than that in the pre-COVID group, while BRS (3.0 (2.2, 4.0) vs. 2.4 (1.8, 3.8), p = 0.470) were not significantly different.

CONCLUSION

During the COVID-19 epidemic, patients with endometriosis may have reduced visits to the hospital, more severe related symptoms, longer length of hospital stays, and worse quality of life, with the possible cause being a disturbance in hormone levels through increased anxiety and depression. This provides a valid clinical basis for optimizing the management of patients with endometriosis and for early psychological intervention during the epidemic.

Evaluation and management of endometriosis

The initial diagnostic investigations for endometriosis are physical examination and pelvic ultrasound. The pelvic examination should include a speculum examination and vaginal palpation. Mobility, fixation and/or tenderness of the uterus and site-specific tenderness in the pelvis should be evaluated. Transvaginal ultrasound and pelvic magnetic resonance imaging are recommended to evaluate the extent of the endometriosis and to determine whether any urinary tract or bowel procedures might also be required during surgical resection. Quality of life should be assessed by using the Endometriosis Health Profile-30, its short version EHP-5 or the generic quality of life questionnaire SF-36. Management of endometriosis is recommended when it has a functional impact (pain, infertility) or causes organ dysfunction. Many gynecological societies have published different guidelines for the evaluation and management of endometriosis. However, the complexity of this disease together with the different available treatments lead to significant discrepancies between the recommendations. Postmenopausal endometriosis should be considered when a patient has a history of symptoms before menopause including dysmenorrhea, dyspareunia, dyschezia, infertility and chronic pelvic pain. Malignant transformation of endometriosis is estimated to occur in about 0.7-1.6% of women affected by endometriosis. Endometriosis is associated with an increased risk of ovarian cancer, specifically clear cell, endometrioid and low-grade serous types.

Serological autoimmune profile of systemic lupus erythematosus in deep and non-deep endometriosis patients

OBJECTIVE

Several studies have reported a high prevalence of autoimmune diseases such as systemic lupus erythematosus (SLE) in endometriosis patients. The aim of this study was to evaluate the SLE autoimmune antibody profile in patients with deep (DE) and non-deep endometriosis (Non-DE).

MATERIALS AND METHODS

Four groups of premenopausal patients were evaluated: patients with DE (n = 50); patients with ovarian endometriomas (Non-DE; n = 50); healthy patients without endometriosis (C group; n = 45); and SLE patients without endometriosis (SLE group; N = 46). Blood samples were obtained and the standard SLE autoimmune profile was evaluated in all patients. Pain symptoms related to endometriosis and clinical SLE manifestations were also recorded.

RESULTS

The DE group presented a statistically significant higher proportion of patients with antinuclear antibodies (ANA) (20%) compared to the Non-DE group (4%) and C group (2.2%). Levels of complement were more frequently lower among DE and Non-DE patients although differences did not reach statistical significance. Similarly, anti-dsDNA antibodies and anticoagulant lupus were positive in more patients of the DE group but did not reach statistical significance. The DE group complained of more arthralgia and asthenia compared to the Non-DE and C groups.

CONCLUSIONS

The results of this study showed higher positivity of ANA and greater arthralgia and asthenia in patients with DE compared with Non-DE patients and healthy controls, suggesting that they may have a higher susceptibility to autoimmune diseases and present more generalized pain.

Psychological interventions improve quality of life despite persistent pain in endometriosis: results of a 3-armed randomized controlled trial

PURPOSE

Despite standard medical treatment endometriosis is often associated with disabling pain and poor quality of life (QoL). Studies indicate that psychological interventions (PIs) may improve pain and QoL, yet studies on the effects of PIs for women with endometriosis are sparse and limited by low-quality study designs. Therefore, this study aimed, in a rigorous three-armed design, to evaluate the effect of PIs on chronic pelvic pain (CPP) and QoL in women with endometriosis.

METHODS

This three-armed parallel, multi-center randomized controlled trial included fifty-eight endometriosis patients reporting severe CPP [≥ 5 for pain intensity measured on a 0-10-point numeric rating scale (NRS)]. Patients were randomly assigned to (1) Specific mindfulness- and acceptance-based psychological intervention (MY-ENDO), (2) Carefully matched non-specific psychological intervention (Non-specific), or (3) A wait-list control group (WL). The primary outcome was pelvic pain intensity/unpleasantness measured on NRS. Secondary outcomes included endometriosis-related quality of life, workability, pain acceptance, and endometriosis-related symptoms. Differences in outcomes between groups at post-treatment follow-up were analyzed using mixed linear models. Analyses were performed on an intention-to-treat basis.

RESULTS

Compared to WL, psychological intervention (MY-ENDO + Non-specific) did not significantly reduce pain. However, psychological intervention did significantly improve the QoL-subscales 'control and powerlessness', 'emotional well-being', and 'social support' as well as the endometriosis-related symptoms 'dyschezia' and 'constipation'. MY-ENDO was not superior to Non-specific.

CONCLUSIONS

Women with endometriosis may have significant and large effects of psychological intervention on QoL despite an ongoing experience of severe CPP.

Endometriosis Symptomatology, Dyspareunia, and Sexual Distress Are Related to Avoidance of Sex and Negative Impacts on the Sex Lives of Women with Endometriosis

BACKGROUND

Endometriosis affects approximately 10% of women and is associated with a range of symptoms including pelvic pain, abnormal bleeding, and painful sexual intercourse. However, very little is known about the relationship between endometriosis-related symptoms and sex.

METHODS

Women with a diagnosis of endometriosis (n = 2060; mean age = 30 years) completed a questionnaire measuring the frequency of endometriosis symptoms, dyspareunia, sexual distress, avoidance of sex, and the perceived negative impact of endometriosis symptoms on sex life.

RESULTS

In bivariate and multivariate logistic regression models with avoidance of sex and perceived negative impact of endometriosis symptoms on sex life as DVs, higher endometriosis symptom frequency, dyspareunia, and sexual distress were associated with greater avoidance of sex and higher perceived negative impact of endometriosis symptoms on sex life. With a two- and three-fold increase in the odds of avoiding sex and reporting a negative impact of endometriosis on sex lives, respectively, for each point increase in dyspareunia. Similarly, there was a 7% to 11% increase in avoidance of sex and the negative impact of endometriosis on sex lives, per one-point increase in symptom frequency and sexual distress.

CONCLUSIONS

The results highlight the considerable impacts of endometriosis symptomatology on women's sex lives and wellbeing. Better medical and counselling services may be needed to ameliorate the negative impact of endometriosis on women's sex lives.

Clinical and sonographic impact of oral contraception in patients with deep endometriosis and adenomyosis at 2 years of follow-up

Nowadays, combined oral contraceptives (COCs) are successfully employed for the treatment of endometriosis (END) and adenomyosis (AD) in a large proportion of patients. However, literature focusing on the clinical and sonographic response to treatment in the long-term follow-up of patients with deep endometriosis (DE) and AD is scarce. The aim of this study was to evaluate the changes in the symptoms and the sonographic exams at 12 and 24 months of follow-up in patients who had received a flexible extended COC regimen containing 2 mg of dienogest/30 μg ethinyl estradiol. This prospective, longitudinal, observational study included women diagnosed with DE and AD presenting no surgical indication and were candidates to treatment with COCs. The presence and severity of dysmenorrhea, non-menstrual pelvic pain, deep dyspareunia, dyschezia and dysuria were evaluated using the Numerical Rating Scale (NRS) at baseline, and at 12 and 24 months of treatment. Transvaginal ultrasound was also performed at these check points searching for criteria of AD and reporting the size of the DE nodules and ovarian endometriomas (OE). Sixty-four patients were included. A significant decrease in the number of patients with severe dysmenorrhea and non-menstrual pelvic pain was reported during follow-up. The mean NRS score for dysmenorrhea, non-menstrual pelvic pain, deep dyspareunia, dyschezia and dysuria was also significantly lower at follow-up. There was a significant reduction in the sonographic number and type of AD criteria during follow-up after treatment. Similarly, a significant decrease in the size of OE and uterosacral ligament involvement in DE was observed at the 12-month follow-up, with a further, albeit not statistically significant, decrease in the 12- to 24-month follow-up. Additionally, torus and rectosigmoid DE decreased in size, although the reduction was not statistically significant at any study point. This prospective study suggests a clinical and sonographic improvement after a flexible extended COC regimen in DE and AD patients, which was significant at 12 months of follow-up. The improvement was more evident in AD and OEs compared with DE. Further research with a longer follow-up, larger sample size and comparison with other treatments is needed.

Application of Deep Learning Model in the Sonographic Diagnosis of Uterine Adenomyosis

BACKGROUND

This study aims to evaluate the diagnostic performance of Deep Learning (DL) machine for the detection of adenomyosis on uterine ultrasonographic images and compare it to intermediate ultrasound skilled trainees.

METHODS

Prospective observational study were conducted between 1 and 30 April 2022. Transvaginal ultrasound (TVUS) diagnosis of adenomyosis was investigated by an experienced sonographer on 100 fertile-age patients. Videoclips of the uterine corpus were recorded and sequential ultrasound images were extracted. Intermediate ultrasound-skilled trainees and DL machine were asked to make a diagnosis reviewing uterine images. We evaluated and compared the accuracy, sensitivity, positive predictive value, F1-score, specificity and negative predictive value of the DL model and the trainees for adenomyosis diagnosis.

RESULTS

Accuracy of DL and intermediate ultrasound-skilled trainees for the diagnosis of adenomyosis were 0.51 (95% CI, 0.48-0.54) and 0.70 (95% CI, 0.60-0.79), respectively. Sensitivity, specificity and F1-score of DL were 0.43 (95% CI, 0.38-0.48), 0.82 (95% CI, 0.79-0.85) and 0.46 (0.42-0.50), respectively, whereas intermediate ultrasound-skilled trainees had sensitivity of 0.72 (95% CI, 0.52-0.86), specificity of 0.69 (95% CI, 0.58-0.79) and F1-score of 0.55 (95% CI, 0.43-0.66).

CONCLUSIONS

In this preliminary study DL model showed a lower accuracy but a higher specificity in diagnosing adenomyosis on ultrasonographic images compared to intermediate-skilled trainees.

Eating Disorders and Disturbed Eating Behaviors Underlying Body Weight Differences in Patients Affected by Endometriosis: Preliminary Results from an Italian Cross-Sectional Study

This study aimed to characterize the prevalence of eating disorders (EDs), disturbed eating behaviors (DEBs), and emotional eating attitudes (EEAs) among patients affected by endometriosis in order to understand a potential crosslink between this impacting gynecological disease and a Body Mass Index shift. A total of 30 patients were recruited at an endometriosis outpatient clinic in Bologna and were assessed by using standardized instruments and specific questionnaires for EDs, DEBs, and EEAs. Sociodemographic information and endometriosis clinical features and history information were collected by adopting a specific questionnaire. Retrospective reports of lifetime Body Mass Index (BMI) changes, current BMI, peak pain severity during the last menstrual period, and the average of pain intensity during the last intermenstrual period were used for a correlation with the mean score from eating-behavior scales' assessment. The preliminary results indicate that, although only 3.33% of endometriosis patients are affected by ED, statistically significant differences at the mean scores of DEBs and EEAs assessment scales were found by stratifying patients on the basis of BMI levels at risk for infertility and coronary heart disease and on the basis of moderate/severe pain levels. The enrichment of the sample size and the recruitment of the control group to complete the study enrollment will allow us to investigate more complex and strong correlation findings and to assess the prevalence of EDs among endometriosis patients.

A Single Session of a Digital Health Tool-Delivered Exercise Intervention May Provide Immediate Relief from Pelvic Pain in Women with Endometriosis: A Pilot Randomized Controlled Study

BACKGROUND

Endometriosis is a debilitating chronic condition that is commonly associated with chronic pelvic pain, affecting approximately 10% of women of reproductive age worldwide. The general principle of pain management in this population involves both pharmacological and surgical interventions. There is also increasing interest in the use of exercise as an alternative non-pharmacological analgesic, but adherence and accessibility to face-to-face exercise-delivery modalities are poor. This study aims to determine the immediate impact of a single session of 'supervised' telehealth-delivered exercise compared to 'self-managed' virtual reality (VR)-delivered exercise on pelvic pain associated with endometriosis.

METHODS

Twenty-two women experiencing pelvic pain due to endometriosis were included and randomized into three groups: (i) VR-delivered exercise group (n = 8); (ii) telehealth-delivered exercise group (n = 8); and (iii) control group (n = 6). The visual analogue scale (VAS) was used to assess the severity of pelvic pain.

RESULTS

There was no statistically significant between-group difference (p = 0.45) in the participants' pain score following a single session of the study interventions (VR or telehealth) or the control. However, a 'medium-to-large' group x time interaction effect (η² = 0.10) was detected, indicating a more favorable pain score change following a single session of telehealth- (pre-post ∆: +10 ± 12 mm) and VR-delivered exercise (pre-post ∆: +9 ± 24 mm) compared to the control group (pre-post ∆: +16 ± 12 mm).

CONCLUSIONS

Our study suggests that a single bout of a 'self-managed' VR-delivered exercise may be as efficacious as a single session of 'supervised' telehealth-delivered exercise in providing immediate relief from pelvic pain associated with endometriosis.

Do expectations determine postoperative disability in women with endometriosis? Study protocol for a clinical mixed-methods observational cohort study

INTRODUCTION

Overall, 20%-30% of women with endometriosis report endometriosis-related disability after successful laparoscopy. This indicates a potential impact of psychological factors, such as expectations, on treatment outcomes. It is already known that expectations determine treatment outcomes in various health conditions, such as cardiologic or gynaecology. Therefore, we investigate the impact of expectations and other psychological factors on patients' course of treatment outcomes after laparoscopy.

METHODS AND ANALYSIS

A longitudinal mixed-methods study with N=300 women treated at a specialised centre of surgical endoscopy and endometriosis will be conducted with one preoperative and eight postoperative assessments of endometriosis-related disability and a priori specified predictors such as expectations.Additionally, two subsamples (each ~n=30) will be either interviewed about their endometriosis-related disability, expectations, and experiences of laparoscopy before and after surgery or asked once per day for 30 consecutive days using ambulatory assessments. Quantitative data will be analysed using multilevel modelling for longitudinal data. Structural content analysis will be used for qualitative data.

DISCUSSION

To optimise treatment for women with endometriosis, it is essential to understand how treatment expectations and other psychological and medical factors influence treatment outcomes after laparoscopy.

ETHICS AND DISSEMINATION

The Ethics Committee of the Psychotherapeutenkammer Hamburg, Germany, gave ethical approval (ROXWELL-2021-HH, 25 June 2021).

High intensity focused ultrasound treatment for adenomyosis: comparison of efficacy based on MRI features

OBJECTIVE

To compare the clinical efficacy of High intensity-focused ultrasound(HIFU) for different types of adenomyosis classified by magnetic resonance imaging (MRI).

METHODS

A total of 227 patients with adenomyosis who underwent HIFU treatment in Suining Central Hospital from January 2014 to December 2019 were included. Based on the preoperative pelvic MRI examination and Kishi isometric classification method, the patients were divided into 4 types according to the location of lesions. There were 82 cases of type I (endogenous type), 75 cases of type II (exogenous type), 34 cases of type III (nodular type), and 36 cases of type IV (heterogeneous type). The results of HIFU treatment for four types of adenomyosis and intraoperative adverse effects were analyzed. The changes of lesion size, dysmenorrhea, and menstrual volume were analyzed at 3 and 6 months after the operation.

RESULT

(1) adverse effects: All patients successfully accepted HIFU treatment under sedation and analgesia. Grade A adverse effects occurred in 51 cases (22.47%) and grade B adverse effects in 3 cases (1.32%). The incidence of adverse effects in type I-IV patients was 21.95%, 22.66%, 23.53%, and 30.56%, respectively. There was no significant difference in the incidence of grade A and B adverse effects in all types, and no grade C-F adverse effects occurred. (2) Ablation effect: The ablation rate of type III(nodular type)patients was (74.7 ± 20.3) %, which was significantly higher than that of the other three types (p < .05). (3) Changes in lesion size: the lesion size of all patients decreased after treatment and the reduction rate gradually increased with time. At 6 months after the operation, the lesion reduction rate of type III patients was (70.8 ± 14.8) %, higher than that of the other three types patients (p < .05). There was no significant difference in the reduction rate of type I, type II and type IV. (4) Remission of menorrhagia: At 6 months after the operation, the total remission rate of type III patients was 100%, while the total remission rate of type IV patients (65.4%, 17/26) that was lower than that of type I, II and III patients(p < .05). (5) Dysmenorrhea relief: At 6 months after the operation, the total dysmenorrhea relief rate of type III patients was 100% and the complete relief rate (28.1%, 18/31) was higher than that of the other three types, which was significant differences (p < .05).

CONCLUSIONS

HIFU is safe and effective in the treatment of different types of adenomyosis, the therapeutic effect of HIFU in patients with type III adenomyosis is better than that of the other three types.

Prevalence and Risk Factors of Central Sensitization in Women with Endometriosis

STUDY OBJECTIVE

To assess prevalence of central sensitization (CS) and its association with demographic and clinical factors in patients with endometriosis.

DESIGN

Single-center, observational, cross-sectional study.

SETTING

Tertiary center.

PATIENTS

Consecutive patients with endometriosis referred to the center from January 15, 2022, to April 30, 2022.

INTERVENTIONS

For each enrolled patient, demographic and clinical data were collected, and the presence of CS was measured using the CS Inventory questionnaire (score ≥40).

MEASUREMENTS AND MAIN RESULTS

Primary study outcome was CS prevalence, and secondary study outcomes were the associations between demographic and clinical factors and CS. The 95% confidence intervals for CS prevalence were obtained with Bayesian-derived Jeffreys method, and the associations between CS and demographic and clinical factors were evaluated with the chi-square test and Fisher's exact test, where appropriate. The variables significantly associated with CS were then included in a multivariable logistic regression model. The significance level was set at .05 for all analyses. During the study period, 285 eligible women were enrolled. CS prevalence was 41.4% (95% confidence interval, 35.8-47.2). At univariable analysis, infertility, moderate to severe pain symptoms (except for dyschezia), altered bowel movements, posterolateral parametrium involvement, hormonal therapy failure (HTF), and most of central sensitivity syndromes were significantly associated with CS occurrence. Multivariable analysis only confirmed the significant association of CS with moderate to severe chronic pelvic pain, posterolateral parametrium involvement, HTF, migraine or tension-type headache, irritable bowel syndrome, and anxiety or panic attacks.

CONCLUSION

CS has a high prevalence in patients with endometriosis, especially in those with moderate to severe chronic pelvic pain, posterolateral parametrium involvement, HTF, and 3 central sensitivity syndromes (i.e. migraine or tension-type headache, irritable bowel syndrome, anxiety or panic attacks). Given the association with HTF, identifying CS through CS Inventory might be useful to counsel the patient and to choose multimodal treatment.

Uterine Anteroposterior Diameter Measured by Transvaginal Sonography is a Predictor for Dysmenorrhea in Patients With and Without Endometriosis: A Pilot Study

PURPOSE

The aim of this study was to determine the correlation between uterine diameters and menstrual abdominal pain intensity in patients with and without endometriosis (EM), and the independent influence of EM on the pain intensity.

METHODS

Uterine diameters and the diagnosis of adenomyosis were ascertained by transvaginal ultrasonography (TVS). Menstrual abdominal pain intensity was estimated by visual analog scale (VAS). Linear regression was used to figure out the impact of uterine diameters and EM on the VAS scores. Logistic regression was used to calculate the correlation between uterine diameters and the diagnosis of adenomyosis. The cutoff values of uterine anteroposterior diameter (AD) to predict dysmenorrhea (VAS ≥ 4) and the diagnosis of adenomyosis were determined by receiver operating characteristic curves.

RESULTS

There were 220 patients with and 233 patients without EM included. Uterine AD independently correlated with the VAS scores in patients with (B = .230, P = .000) and without (B = .203, P = .000) EM. A uterine AD of 39.5 mm predicted dysmenorrhea in both groups. The presence of EM increased the VAS scores by 1.151 points when controlling for uterine diameters. Uterine AD also independently correlated with the diagnosis of adenomyosis under TVS in patients with (OR = 1.212, 95% CI = 1.130-1.301; P = .000) and without (OR = 1.192, 95% CI = 1.123-1.263; P = .000) EM. A uterine AD of 38.5 and 39.5 mm predicted the diagnosis of adenomyosis under TVS in patients with and without EM, respectively.

CONCLUSIONS

Increased uterine AD, which is probably ascribed to adenomyosis, plays an important role in augmented menstrual abdominal pain intensity. Meanwhile, the presence of EM reinforces the pain.

Does group physiotherapy improve pain scores and reduce the impact of pelvic pain for women referred with persistent pelvic pain? A clinical trial

Introduction:

This study aimed to test group Physiotherapy sessions – pain education and supervised exercise − in addition to individual consultations, for women referred with persistent pelvic pain (with/without endometriosis), with the primary outcomes being pain scores and pain impact.

Methods:

Parallel study design with three treatment arms: (1) usual care: a suite of individual Physiotherapy consultations; (2) introductory group pain education session followed by usual care and (3) introductory group pain education session followed by usual care and an 8-week supervised group exercise programme.

Results:

Ninety women were recruited (30/treatment arm), with 66 women (73%) completing their allocated treatment. Participants were aged between 16 and 51 years; endometriosis was confirmed in 41% ( n = 27/66) of the study population. Data was analysed using descriptive and inferential statistics. Statistically significant gains ( p < 0.05) in pain scores and pelvic pain impact scores were observed in all arms. Between groups, there was statistically significant improvement ( p < 0.05) in pelvic pain impact score for those who attended the group pain education session followed by usual care (arm 2), compared to usual care (arm 1) alone. There was no significant added improvement with the weekly supervised group exercise programme (arm 3), when compared to those who received the group pain education programme and usual care (arm 2).

Conclusion:

This study has demonstrated positive benefits of a group pain education session on pain scores and pelvic pain impact for women referred with persistent pelvic pain, when added as a precursor to individual Physiotherapy consultations.

What is the evidence of effectiveness of non-pharmaceutical, non-surgical, biopsychosocial interventions for body image and pain management in individuals with endometriosis? A systematic review

Aim:

To identify and review the success of non-pharmaceutical, non-surgical biopsychosocial interventions in individuals with endometriosis, in managing pain and improving body image.

Methods:

Cochrane, EBSCO, IBSS, NICE, Open Grey, OVID, Proquest, Scopus and Science Direct were searched in April 2021, using inclusion and exclusion criteria.

Data collection and analysis:

Five randomised control trials, and one controlled clinical trial resulted from the search. Study quality was assessed using the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool. Studies were synthesised by intervention type, into physical only, and physical and psychological.

Results:

Across the six papers, 323 participants were recruited, through medical records or self-referral, and treatments largely administered by specialist practitioners. From the EPHPP quality assessment,2 weak quality papers, and four moderate quality papers found improvements to pain, with large effect sizes in four papers. No studies used established body image measures to examine intervention effects on body image, and all lacked health psychology theoretical basis. There were common issues in selection bias, confounders and blinding.

Conclusion:

Without gold-standard methodology, evidence of effectiveness cannot be concluded. However, there is promising rationale if these issues are addressed.
