Endometriosis in an adolescent population: the Emory experience

Distribution of endometriosis phenotypes according to patients' age in adult women with surgical evaluation

STUDY QUESTION

What is the distribution of endometriosis phenotypes according to age in adult women undergoing surgery?

SUMMARY ANSWER

The phenotype of endometriosis did not significantly vary after 24 years old.

WHAT IS KNOWN ALREADY

The phenotypic evolution of endometriosis over time remains unclear. While adolescents can exhibit any type of endometriosis lesions, ovarian endometriosis (OMA) and/or deep-infiltrating endometriosis (DIE) tend to increase with age in young adults. In adulthood, understanding the evolution of lesions is crucial for disease management, but the literature on this subject is limited. This study aims to examine the distribution of endometriosis phenotypes in relation to age among adult patients requiring surgical treatment.

STUDY DESIGN, SIZE, DURATION

This observational cohort study included patients aged between ≥18 and ≤42 years, who underwent surgery for benign gynecological conditions at our institution between January 2004 and December 2022. A standardized questionnaire was completed for each patient during a face-to-face interview conducted by the surgeon in the month preceding surgery. Women with histologically proven endometriosis were included.

PARTICIPANTS/MATERIALS, SETTING, METHODS

The distribution of endometriosis phenotypes (isolated superficial (SUP) endometriosis, OMA ± SUP, DIE ± SUP/OMA) was compared between young adults (≤24 years) and adults (>24 years) and among adults (25-28 years, 29-33 years, 34-38 years, 39 to ≤42 years) using univariate and multivariate analysis. The distribution of different subtypes of DIE (uterosacral ligament(s), vagina, bladder, intestine, and ureter), OMA size, and intensity of pain symptoms were also examined.

MAIN RESULTS AND THE ROLE OF CHANCE

A total of 1311 adult women with histologically proven endometriosis were included. In women aged 24 years or younger (n = 116), the distribution of endometriosis phenotypes differed significantly from women older than 24 years (n = 1195): The frequency of the DIE ± SUP/OMA phenotype was lower (41.4% versus 56.1%, respectively), while the rate of isolated superficial lesions was higher (from 32.0% versus 25.9%) (P = 0.001). In the group of women aged >24 years, a significantly higher proportion of vaginal DIE lesions (P = 0.012) and a lower proportion of uterosacral ligament DIE lesions (P = 0.004) were found compared to women aged ≤24 years. No significant differences were observed in terms of endometrioma size. Between the ages of 25 and 42 years, there were no significant changes in the distribution of endometriosis phenotypes after univariate and multivariate analysis. The distribution of subtype of DIE lesions did not significantly change with age between 25 and 42 years. Concerning pain symptom scores, there was a significant decrease with age for dysmenorrhea and dyspareunia.

LIMITATIONS, REASONS FOR CAUTION

Inclusion of only surgical patients may have introduced a selection bias. Women referred to our center may have suffered from particularly severe clinical forms of endometriosis.

WIDER IMPLICATIONS OF THE FINDINGS

This study highlights that endometriosis presentation did not change with age in adult women. Further research on endometriosis phenotype evolution is necessary to assist practitioners in clinical decisions and treatment strategies.

Ovarian endometrioma: a report of a pediatric case diagnosed prior to menstruation

BACKGROUND

Ovarian endometriomas (OEs) are rarely found in the pediatric population, especially before menstruation. We report a 6-year-old girl who was postoperatively diagnosed with OE before menstruation.

CASE PRESENTATION

A 6-year-old girl presented to a local pediatrician with abdominal pain and vomiting. Abdominal ultrasonography revealed a multilocular cystic lesion to the left of the bladder. Magnetic resonance imaging (MRI) revealed similar findings, with the contents of the cyst showing a low signal on T1-weighted imaging and a high signal on T2-weighted imaging. The patient was referred to our institution for further examination. Enhanced computed tomography (CT) showed a multilocular cystic lesion sized 56 × 44 × 30 mm with partial calcification. The left ovarian vein was dilated, suggesting the origin of the tumor to be the left ovary. Extirpation of the lesion was performed under laparoscopic assistance. Pathological findings indicated an ovarian endometrioma. To our knowledge, this is the youngest report of an OE diagnosed in a patient prior to menstruation.

CONCLUSIONS

OEs in children before menstruation are extremely rare; thus, the long-term prognosis is yet to be determined.

Is Neonatal Uterine Bleeding Involved in Early-Onset Endometriosis?

BACKGROUND

There has been considerable progress in our understanding of endometriosis, but its pathophysiology remains uncertain. Uncovering the underlying mechanism of the rare instances of endometriosis reported in early postmenarcheal years and in girls before menarche can have wide implications.

METHODS

We conducted a literature review of all relevant articles on Medline.

RESULTS

In the review, we explore the pathogenetic theories of premenarcheal endometriosis, the role of retrograde menstruation in the adult and its potential role in early-onset disease, as well as the factors that argue against the existence of a link between early-onset endometriosis (EOE) and neonatal uterine bleeding (NUB).

CONCLUSIONS

As with endometriosis in adult women, the pathogenesis of early-onset disease remains unclear. A link between NUB and EOE is plausible, but there are considerable challenges to collating supporting evidence. The state of our understanding of early uterine development and of the pathophysiology of NUB leaves many unknowns that need exploration. These include proof of the existence of viable endometrial cells or endometrial mesenchymal stem cells in NUB, their passage to the pelvic cavity, their possible response to steroids, and whether they can reside within the pelvic cavity and remain dormant till menarche.

Surgical Considerations in the Management of Adolescent Endometriosis-An Expert Commentary

Given the complexities and controversies that exist in diagnosing adult endometriosis, as well as optimizing medical and surgical management, it is not surprising that there is even more ambiguity and inconsistency in the optimal surgical care of endometriosis in the adolescent. This collaborative commentary aimed to provide evidence-based recommendations optimizing the role of surgical interventions for endometriosis in the adolescent patient with input from experts in minimally invasive gynecologic surgery, pediatric and adolescent gynecology, and infertility/reproductive medicine.

Diagnosis and treatment of early-stage endometriosis by Transvaginal Hydro laparoscopy

Background: Transvaginal Hydro Laparoscopy (THL) is known as a minimal invasive procedure allowing endoscopic exploration of the female pelvis. Objective: To evaluate the possibilities of the THL as a tool for early diagnosis and treatment of minimal endometriosis. Materials and methods: A retrospective study of a consecutive series of 2288 patients referred for fertility problems to a tertiary centre for reproductive medicine was undertaken. Mean duration of infertility was 23.6 months (SD ±11-48), mean age of patients was 31.25 (SD± 3.8y). With normal findings at clinical and ultrasound examination patients underwent, as part of their fertility exploration, a THL. Main outcome measures: Evaluation of feasibility, identified pathology and pregnancy rate. Results: Endometriosis was diagnosed in 365 patients (16%); the localisation was higher on the left side (n=237) than on the right side (n=169). Small endometriomas, with diameters between 0.5 and 2 cm, were present in 24.3% (right side in 31, left side 48 and bilateral 10). These early lesions were characterised by the presence of active endometrial like cells and a pronounced neo-angiogenesis. Destruction of the endometriotic lesions with bipolar energy resulted in an in vivo pregnancy rate (spontaneous/IUI) of 43.8% (CPR after 8 months: spontaneous 57.7%; IUI/AID 29.7%). Conclusion: THL allowed in a minimally invasive way an accurate diagnosis of the early stages of peritoneal and ovarian endometriosis with the possibility of offering treatment with minimal damage. What is new? This is the largest series reporting the usefulness of THL for the diagnosis and treatment of peritoneal and ovarian endometriosis in patients without obviously visible preoperative pelvic pathology.

Serum kisspeptin levels in deep-infiltrating, ovarian, and superficial endometriosis: A prospective observational study

The diagnosis of endometriosis may delay for many years due to non-deterministic symptoms and avoiding surgical interventions. Kisspeptins are hormones that interact with endometrial tissue to limit invasions during placentation and various cancers and are suggested to be also associated with endometriosis. This study evaluated if serum kisspeptin levels are associated with the invasion depth in endometriosis. Forty patients between 18 and 45 years of age and admitted to a tertiary-care Obstetrics and Gynecology Department between 2020 and 2021 with a diagnosis of endometriosis, and 40 patients without endometrioma were included in the study. Demographic, obstetric, clinical, and biochemical characteristics were evaluated in patients with superficial (SE) and deep infiltrating (DIE) endometriosis and healthy controls. Twenty patients (50%) had SE, 14 (35%) had DIE, and 22 (55%) had endometrioma in the patient group. Fertility rates were higher among controls, but similar between patients with SE and DIE. CA125 levels were significantly higher in the DIE group. SE and DIE groups had similar kisspeptin values, significantly higher than controls. CA125 and kisspeptin levels were not correlated in study groups. Serum kisspeptin levels were significantly different between endometriosis patients and healthy controls. However, kisspeptin levels were unable to differentiate endometriosis severity. Our results suggest that kisspeptins might play a role in the pathogenesis of endometriosis, which needs further assessment in more comprehensive studies.

Prevalence of endometriosis and adenomyosis at transvaginal ultrasound examination in symptomatic women

INTRODUCTION

Prevalence of endometriosis is commonly reported based on surgery findings and varies widely depending on study population and indication for surgery. Symptoms such as dysmenorrhea, pelvic pain, dyspareunia, dysuria, and dyschezia can be associated with endometriosis and adenomyosis. Transvaginal ultrasound examination is proposed to be the first-line diagnostic method, nevertheless there are no published ultrasound-based studies reporting prevalence of endometriosis and adenomyosis in symptomatic women other than those scheduled for surgery. The aim of this study was to determine the prevalence of endometriosis and adenomyosis as assessed by transvaginal ultrasound in women with symptoms suggestive of endometriosis and adenomyosis.

MATERIAL AND METHODS

This is a retrospective cross-sectional study performed at a tertiary-care center including 373 symptomatic women who were systematically examined with transvaginal ultrasound by an experienced ultrasound examiner. Before ultrasound examination women filled in a questionnaire including self-assessment of the severity of their symptoms (dysmenorrhea, chronic pelvic pain, dyspareunia, dysuria, dyschezia) using a visual analog scale. Abnormal findings in the uterus, ovaries, bowel, urinary bladder, uterosacral ligaments, and rectovaginal septum were noted, and their size and location were described. Prevalence of endometriosis, adenomyosis, endometrioma, and deep endometriosis in different anatomical locations was reported.

RESULTS

Prevalence of ovarian endometrioma and/or deep endometriosis was 25% and of adenomyosis was 12%. Prevalence of endometrioma was 20% and of deep endometriosis was 9%, for each location being 8% in the bowel, 3% in the uterosacral ligaments, 3% in the rectovaginal septum and 0.5% in the urinary bladder.

CONCLUSIONS

In symptomatic women examined with transvaginal ultrasound by an experienced ultrasound examiner, ovarian endometrioma and/or deep endometriosis was found in one of four women and adenomyosis in one of nine women. Deep endometriosis was present in one of 11 women. Despite having symptoms, half of the women had no abnormal ultrasound findings.

Age-dependent phenotypes of ovarian endometriomas

Purpose

To analyze the characteristics of the ovarian endometrioma (OE) across the life span of a woman. In the past, the OE has traditionally been viewed as a single, monolithic disease. Today, there are emerging data indicating that OE phenotypes differ according to the age of the woman.

Method

A narrative review of original articles on OE indexed by PubMed.

Results

When appearing in infancy and early adolescence, OE may be the consequence of endometrial cells retrogradely shed with neonatal uterine bleeding. The post-menarcheal variant, manifesting itself during full adolescence, is singularly frequent in the presence of vaginal or uterine outflow obstructive anomalies. The typical and most frequent adult phenotype is characterized by increasing fibrosis and a tendency to progress; its mere presence exerts a detrimental effect on the surrounding healthy ovarian tissue. In postmenopause, an old lesion may be reactivated in the presence of exogenous or endogenous estrogens, or even be produced ex novo; rarely, it can spread to a variety of organs and structures and even degenerate causing malignancies.

Conclusions

Given the existence of these variants, it is important to agree on management guidelines that take into consideration these different phenotypes.

Feasibility of two robotic single-site surgery techniques for adolescent endometriosis: Focal versus butterfly

OBJECTIVE

This study examined the feasibility of robotic laparoendoscopic single-site surgery (LESS) for the treatment of adolescent endometriosis (n = 36). Additionally, we assessed a novel technique known as butterfly resection for severe cases.

METHODS

This was a retrospective study of women from 12 to 21 years old who received therapeutic robotic LESS for symptomatic endometriosis by a single experienced surgeon.

RESULTS

There were 32 cases of peritoneal and four cases of deep infiltrating endometriosis (DIE). Focal resection was performed in 9/32 peritoneal and all DIE cases; butterfly resection was performed in the remaining 23/32 peritoneal. At 3 months, 16/23 had complete resolution of pelvic pain in the butterfly group versus 10/13 in the focal group (P = 0.64).

CONCLUSION

Robotic LESS produces safe outcomes with low complication rates. Butterfly resection may be considered for extensive lesions, with similar levels of pain relief compared to traditional focal resection techniques.

CAPSULE

Single-site robotic surgery produces safe outcomes with low complication rates in adolescents with endometriosis, with techniques customized based on disease severity.

Endometriosis: Epidemiology, Classification, Pathogenesis, Treatment and Genetics (Review of Literature)

Endometriosis is a “mysterious” disease and its exact cause has not yet been established. Among the etiological factors, congenital, environmental, epigenetic, autoimmune and allergic factors are listed. It is believed that the primary mechanism of the formation of endometriosis foci is retrograde menstruation, i.e., the passage of menstrual blood through the fallopian tubes into the peritoneal cavity and implantation of exfoliated endometrial cells. However, since this mechanism is also observed in healthy women, other factors must also be involved in the formation of endometriosis foci. Endometriosis is in many women the cause of infertility, chronic pain and the deterioration of the quality of life. It also represents a significant financial burden on health systems. The article presents a review of the literature on endometriosis—a disease affecting women throughout the world.

Strengths and weaknesses in the diagnostic process of endometriosis from the patients' perspective: a focus group study

OBJECTIVES

Endometriosis is characterized by a long interval between onset of symptoms and diagnosis. Detailed information about the patients' perspective on the diagnostic delay of endometriosis is scarce. The aim of this study was to identify strengths and weaknesses in the diagnostic process of endometriosis from the patients' perspective.

METHODS

Qualitative study with semi-structured focus groups. Participants were women between 18 and 45 years old with a recently confirmed diagnosis. The focus groups were audio recorded and fully transcribed. Grounded theory methodology was applied for data analysis.

RESULTS

Six focus groups were organized, in which 23 women participated. Mean time from start of symptoms to diagnosis was 8.5 years. Dominant themes were knowledge about normal menstruation and endometriosis, being believed and acknowledged by medical staff, and collaboration between health care providers including fast referral to a gynaecologist. Barriers to a timely referral and diagnosis were young age, normalization of symptoms and a lack of awareness in general practitioners. Facilitating factors included adequate knowledge and skills of the general practitioner, a desire for pregnancy and persisting in a request for specialist consultation by the patient.

CONCLUSIONS

The diagnostic process of endometriosis is hampered by delayed consultation, inadequate appraisal of symptoms by general practitioners and the interaction between patients and medical professionals. Efforts should be made to increase public awareness and to provide medical staff with sufficient knowledge and skills to adequately acknowledge presented symptoms.

Hydroxychloroquine might reduce risk of incident endometriosis in patients with systemic lupus erythematosus: A retrospective population-based cohort study

BACKGROUND

SLE, which is common in women, is commonly treated with HCQ, an anti-inflammation medication. Reproductive-age women with SLE are prone to be impacted by endometriosis. This study analyzes the relationship between HCQ and endometriosis patients with SLE in order to determine whether HCQ is effective for treating the latter.

METHODS

This population-based, retrospective cohort study analyzed the SLE risk in a cohort of newly diagnosed SLE patients with endometriosis during 2000 through 2013. Controls were selected at a 1:2 ratio through age-matching using the greedy algorithm. The Cox proportional hazard model was used to analyze the association between HCQ use and endometriosis incidence. Four different Cox regression models were used. Lastly, sensitivity analysis with PSOW and IPW was implemented to evaluate the hazard ratio (HR) of endometriosis after exposure with HCQ.

RESULTS

In the cohort where age and sex matched high and low HCQ dosage, the average follow-up time was about 1 year. The cohort's overall incidence rates of endometriosis were 44.54 and 90.03 per 100000 person-month for high and low dosage respectively. The high dose group's conditional hazard ratio (aHR) for incidental endometriosis was 0.482 (CI = 0.191 to 1.213). The incidence rate and Kaplan-Meir curves of endometriosis were consistent with the results for the cohort.

CONCLUSION

This study demonstrated that SLE patients continuously treated with HCQ have a lower risk of developing endometriosis. Clinically, HCQ can be beneficial for endometriosis patients with SLE.

Role of medical treatment of endometriosis

Endometriosis is a chronic benign disease that affects women of reproductive age. Medical therapy is often the first line of management for women with endometriosis in order to ameliorate symptoms or to prevent post-surgical disease recurrence. Currently, there are several medical options for the management of patients with endometriosis and long-term treatments should balance clinical efficacy (controlling pain symptoms and preventing recurrence of disease after surgery) with an acceptable safety-profile. Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used in the treatment of chronic inflammatory conditions, being efficacious in relieving primary dysmenorrhea. Combined oral contraceptives and progestins, available for multiple routes of administration, are commonly administered as first-line hormonal therapies. Several studies demonstrated that they succeed in improving pain symptoms in the majority of patients; moreover, they are well tolerated and not expensive. Gonadotropin-releasing hormone-agonists are prescribed when first line therapies are ineffective, not tolerated or contraindicated. Even if these drugs are efficacious in treating women not responding to COCs or progestins, they are not orally available and have a less favorable tolerability profile (needing an appropriate add-back therapy). Because few data are available on long-term efficacy and safety of aromatase inhibitors they should be reserved only for women with symptoms who are refractory to other treatments only in a research environment. Almost all of the currently available treatment options for endometriosis suppress ovarian function and are not curative. For this reason, research into new drugs is unsurprisingly demanding. Amongst the drugs currently under investigation, gonadotropin-releasing hormone antagonists have shown most promise, currently in late-stage clinical development. There is a number of potential future therapies currently tested only in vitro, in animal models of endometriosis or in early clinical studies with a small sample size. Further studies are necessary to conclude whether these treatments would be of value for the treatment of endometriosis.

Adolescent Endometriosis

Importance

Endometriosis is a major health concern in the adolescent population and significantly impacts daily physical and psychosocial functioning. Endometriosis can have differing presentations in this population, and the diagnosis often involves long delays and multiple visits to specialists.

Objective

The aim of this review is to discuss adolescent endometriosis, factors specific to this population, accurate diagnosis, and evidence-based surgical and medical management.

Evidence Acquisition

Computerized searches on the topic of endometriosis and adolescent endometriosis were completed. References from identified sources were then searched manually to allow for a thorough review. Data from relevant sources were synthesized to create the review.

Results

The literature supports endometriosis as a frequent cause of secondary dysmenorrhea. The characteristics of adolescents with endometriosis are shown to differ from those of adults. Initial medical therapy includes nonsteroidal anti-inflammatory drugs and combined hormonal contraceptives, but laparoscopy does have a role in the adolescent population, particularly those who have inadequate response to these treatments. Adolescent endometriosis may have a different appearance and be of all stages. Medical therapies are similar to that of the adult population; however, the benefits of medical and surgical management must be tailored to the adolescent patient.

Conclusions and Relevance

Adolescent endometriosis is likely a more prevalent cause of dysmenorrhea than currently appreciated. A high index of suspicion combined with recognition of risk factors and history-based markers of endometriosis may help identify adolescent endometriosis earlier and avoid delays in diagnosis. Expert opinion supports earlier laparoscopic evaluation in patients with symptoms unresponsive to oral medications, those who have failed initial medical therapy, or those who have evidence of deeply invasive disease, such as an endometrioma. Surgeons should be familiar with the unique appearance of lesions in the adolescent and understand the evidence as it relates to surgical therapy. Postoperative medical management is generally advocated by many, although the efficacy remains unclear at present.

Endometriosis in adolescent and young women

Endometriosis in adolescence represents a specific variant of the disease with its own characteristics and, in some cases, even a possibly different pathogenesis. It has its own clinical presentation, diagnostic and therapeutic modalities. The condition is not rare as once thought and certainly deserves attention in view of increasing evidence of its likely progressive nature. Numerous theories for Its pathogenesis have been formulated and they have been divided into two main categories: the 'in-situ' and the 'transplantation' hypotheses. Clinical manifestations include as the prevailing symptom a persistent chronic pelvic pain, despite medical treatment, manifested under various forms: dysmenorrhea, acyclic chronic pain, acute abdominal pain and migraines. These symptoms can substantially affect the quality of life on an adolescent. At histopathology, adolescent endometriosis is characterized by a high proportion of subtle, clear, red or vesicular implants and by the rarity of deep nodules. Frequently, the picture includes ovarian endometriomas. In some adolescent girls, lesions may regress or even disappear, probably through immune suppression; in others, chronic stress, unhealthy diet or lifestyle such as high-fat diet, may accelerate lesional progression and cause symptoms. Classically, management of adolescent endometriosis has been centered on attempts to treat dysmenorrhea; today both medical and surgical modalities have the potential to improve quality of life, alleviate symptoms, prevent the development of more severe disease and minimize risks for future fertility in adolescents. Nonetheless, at present, medical treatments are considered the first line of interventions in treating young women.

The Prevalence of Endometriosis in Adolescents with Pelvic Pain: A Systematic Review

STUDY OBJECTIVE

Endometriosis is a recognized cause of pelvic pain in adolescents with menstrual symptoms that significantly affect education, activity, and social interactions. We aim to provide an updated systematic review of the prevalence of endometriosis in adolescents with pelvic pain presenting for gynecological investigation.

DATA SOURCES

We searched Medline, Embase, and Cinahl from 2011 to July 2019.

METHODS OF STUDY SELECTION

We included cohort studies of adolescents with pelvic pain undergoing gynecological investigation. Two authors independently selected studies and extracted study characteristics and prevalence data. Methodological quality was assessed using the Critical Appraisal Skills Program for cohort studies.

RESULTS

This updated systematic review evaluated a total of 19 studies including 1243 symptomatic adolescents. In all, 648 of 1011 (64%) adolescents undergoing laparoscopy were found to have endometriosis. The prevalence ranged from 25% to 100%, with a mean prevalence of 64%. Thirteen studies including 381 participants categorized disease severity using the revised American Society of Reproductive Medicine classification. Among these, 53% of participants (201/381) had stage I, 28% (105/381) had stage II, 20% (76/381) had stage III, and 13% (49/381) had stage IV disease.

CONCLUSIONS

The prevalence of endometriosis among adolescents with pelvic pain symptoms is high. Endometriosis is treatable, and prompt recognition will help to ensure that adolescents are signposted earlier to appropriate specialists. The management of adolescents with suspected endometriosis should be consistent with best practice guidance. Despite recommendations to increase the awareness and knowledge of endometriosis in adolescence, minimal research has followed.

Comparison of cytokines in the peritoneal fluid and conditioned medium of adolescents and adults with and without endometriosis

PROBLEM

To compare inflammatory- and immune-associated peritoneal cytokines of adolescents and adults with and without endometriosis.

METHODS OF STUDY

In a nested case-control study in multiple university-affiliated scientific centers, ten adolescents and thirteen adults with visually and histologically confirmed endometriosis (cases), thirteen adolescents with visually suspected endometriosis but indeterminate (seven patients) or negative (six patients) histology, and fifteen adults undergoing surgery for non-malignant gynecologic disease without endometriosis (controls) underwent laparoscopic aspiration of peritoneal fluid (PF), from which PF and conditioned medium (CM) cytokine levels were assayed.

RESULTS

Compared to adults with endometriosis, MCP-3, IL-12p40, MIP-1β, and IL-15 were significantly higher among adolescents with endometriosis, while TNF-β and CTACK were lower among adolescents. These differences were similar comparing adolescents with endometriosis to adult controls except for MIP-1β, which was not statistically different. MIP-1β was, however, the only cytokine observed to differ between adult cases and controls. There were no significant differences in CM cytokines among the three groups. Results were similar when analyses were restricted to samples collected (a) during menstrual cycle days 1-10, (b) from patients unexposed to exogenous hormones, or (c) from all adolescents despite presence or absence of histologic endometriosis.

CONCLUSION

Biologically relevant and statistically significant differences in six PF cytokines were observed and suggest a more pro-invasion cytokine profile among adolescents with endometriosis. Adolescents with endometriosis have unique peritoneal cytokine profiles and molecular behavior when compared to adults with and without endometriosis.

Prevalence of occult microscopic endometriosis in clinically negative peritoneum during laparoscopy for chronic pelvic pain

OBJECTIVE

 To determine the prevalence of occult microscopic endometriosis in patients with chronic pelvic pain and negative laparoscopy.

METHODS

A retrospective cross-sectional study included women who underwent laparoscopic evaluation for chronic pelvic pain by three fellowship-trained gynecologic surgeons at a community hospital from January 2011 to December 2016. The aim was to evaluate the prevalence of microscopic endometriosis in this population.

RESULTS

 In 142 patients with clinically negative peritoneum on laparoscopy, 39% had occult microscopic endometriosis. Cramping pain score during menses was found to be lower in the positive biopsy group (6.9 vs 8.0, P=0.046). No differences were appreciated in age of menarche, pain during various parts of the menstrual cycle, or duration of symptoms. The biopsy-positive group had a younger age at time of evaluation, although not statistically significant (P=0.179). Current use of hormones affected neither biopsy results nor menstrual or pain characteristics. Detection was similar between robotic and laparoscopic cases and operative morbidity was minimal.

CONCLUSION

Occult microscopic endometriosis may be present in approximately 39% of patients with clinically negative appearing peritoneum undergoing laparoscopy for chronic pelvic pain. Given this, biopsies should be performed in patients undergoing laparoscopy who do not have visible lesions.

Management of endometriosis from diagnosis to treatment: roadmap for the future

Endometriosis, in spite of decades of research on the topic, remains a mysterious and elusive disease. Both in the fields of diagnosis and treatment, many issues remain unresolved, and the scientific community strives in trying to find universal criteria for diagnosis, and algorithms of treatment that may be universally applied. Recently, there has been a shift away from the view of the need of invasive diagnosis and therapy with the universal use of laparoscopy. Today the diagnosis of endometriosis may be reliably performed with noninvasive methods, and therapy can be nonsurgical in most cases. Recent guidelines state that diagnostic laparoscopy may be better seen as a second line of investigation, whereas medical therapy with either oral estroprogestins or progestogens is the first therapeutic option in case of associated pain. A thorough discussion with the patient should address all the available treatments, so as to make a shared decision on which treatment best fits the needs of that single patient.

Endometriosis in adolescents

PURPOSE OF REVIEW

The current article addresses recent literature regarding the diagnosis and management of endometriosis in adolescents.

RECENT FINDINGS

An increasing body of literature suggests that advanced-stage endometriosis (revised scoring system of the American Society for Reproductive Medicine Stage III or IV) and deeply invasive endometriosis are relatively common in adolescents. There remains limited data on the efficacy of postoperative hormonal management of endometriosis in the adolescent population.

SUMMARY

Strong consideration should be made for surgical diagnosis of endometriosis in adolescents with pelvic pain, including noncyclic pain, with a concurrent family history of endometriosis and personal history of atopic disease. More research is needed regarding the benefits of the routine use of hypoestrogenic and other hormonal agents in the prevention of disease progression and long-term sequela in adolescents with endometriosis.

Spectrum of symptoms in women diagnosed with endometriosis during adolescence vs adulthood

BACKGROUND

Endometriosis symptoms often start at a young age, and the time between symptom onset and endometriosis diagnosis can be several years. It is not clear whether the symptoms that are experienced by adolescents differ from adults. Better understanding may shorten the often lengthy delay in diagnosis.

OBJECTIVE

The purpose of the study was to further elucidate the symptom presentation of adolescents as compared with adults to determine whether differences existed, based on age at surgical diagnosis that could impact time to diagnosis.

STUDY DESIGN

This investigation was a cross-sectional study at enrollment within a longitudinal cohort of adolescents and women with endometriosis. The population-based cohort was recruited from 2 tertiary care centers and the surrounding communities. Participants included adolescents (diagnosed at ≤18 years old; n=295) and adults (diagnosed at >18 years old; n=107) with surgically confirmed endometriosis who were enrolled into The Women's Health Study: From Adolescence to Adulthood. Participants completed an expanded version of the World Endometriosis Research Foundation Endometriosis Phenome and Biobanking Harmonization Project standard clinical questionnaire that included items regarding menstrual history, associated symptoms, and pain. Chi-square or Fisher's exact tests were applied to categoric data; Wilcoxon rank sum tests were applied to continuous data.

RESULTS

Most participants (90%) experienced moderate-severe menstrual pain. On average, 3 doctors were seen before diagnosis, regardless of age at presentation (range, 0-25 years). Time from symptoms to diagnosis averaged 2 years for adolescents and 5 years for adults (P<.001). More adolescents (50%) than adults (33%) reported pain starting at menarche (P=.002) and nausea accompanying pain (69% vs 53%; P=.01). Noncyclic, general pelvic pain was prevalent. One-half of the participants reported relief of their general pelvic pain after a bowel movement. Pain interfered with work/school, daily activities, exercise, and sleep to a moderate-extreme degree; difficulties were similar by age at diagnosis.

CONCLUSIONS

Pelvic pain was severe and noncyclic and negatively impacted quality of life. At our tertiary care centers, symptoms of endometriosis did not differ between women surgically diagnosed during adolescence compared with those diagnosed as adults. Adolescents had more nausea and symptom onset at menarche. Multi-year delays in diagnosis were common. Clinicians should be aware of these alternate symptom patterns and include endometriosis in their differential diagnosis for both adolescent and young adult women who experience noncyclic pelvic pain and nausea.

A focus on the distinctions and current evidence of endometriosis in adolescents

Endometriosis (EM) occurring in adolescents presents distinct clinical and histologic characteristics compared to the disease in women. Because the symptoms of EM are nonspecific, often overlapping with those experienced in a range of gynecological and gastrointestinal conditions, the process of reaching a diagnosis of EM is often delayed. The diagnosis of EM is suspected depending on the history and the symptoms and signs, is corroborated by physical examination and imaging techniques, and is finally proved by histological examination of specimens collected during laparoscopy. Currently, there is insufficient evidence to make strong recommendations for management in adolescents who may have EM. This short report reviews some peculiarities of EM in adolescents and provides an update of recent knowledge of the diagnosis and treatment of EM. We hope that the present contribution may help to bring more attention to the clinical diagnosis of EM and consequently aid in decreasing diagnostic delay.

Peculiar Aspects of Endometriosis in Adolescents

Although documented rates of endometriosis in adolescent patients undergoing laparoscopy for chronic pelvic pain range from about 25% to 45%, adolescent endometriosis has received limited attention in terms of research activity and follow-up studies. In this manuscript, distinctive characteristics of adolescent and young endometriosis have been considered in order to define pathogenetic and scientific concepts that might be useful in clarifying some aspects of the adult disease as well. Some highlights relative to the cellular origin of the disease can be derived from reported cases before menarche, from the appearance of endometriotic lesions in teenagers (mostly stage I-II endometriosis), and from the relative infrequency of ovarian endometriotic cysts in this population. Adolescents and young patients might be also particularly useful for studying the natural course of the disease. To this end, clinical manifestations and recurrence patterns of the disease in adolescent patients need to be elucidated. Differences in clinical aspects of the disease between the adult and young populations are presented. Risk of recurrence and potential risk factors involved in the reappearance of the disease in teenagers are completely unknown. (Journal of Endometriosis 2010; 2: 19–25)

Endometriosis: Diagnosis and Management

Objective

To improve the understanding of endometriosis and to provide evidence-based guidelines for the diagnosis and management of endometriosis.

Outcomes

Outcomes evaluated include the impact of the medical and surgical management of endometriosis on women's experience of morbidity and infertility.

Methods

Members of the guideline committee were selected on the basis of individual expertise to represent a range of practical and academic experience in terms of both location in Canada and type of practice, as well as subspecialty expertise along with general gynaecology background. The committee reviewed all available evidence in the English and French medical literature and available data from a survey of Canadian women. Recommendations were established as consensus statements. The final document was reviewed and approved by the Executive and Council of the SOGC.

Results

This document provides a summary of up-to-date evidence regarding diagnosis, investigations, and medical and surgical management of endometriosis. The resulting recommendations may be adapted by individual health care workers when serving women with this condition.

Conclusions

Endometriosis is a common and sometimes debilitating condition for women of reproductive age. A multidisciplinary approach involving a combination of lifestyle modifications, medications, and allied health services should be used to limit the impact of this condition on activities of daily living and fertility. In some circumstances surgery is required to confirm the diagnosis and provide therapy to achieve the desired goal of pain relief or improved fecundity. Women who find an acceptable management strategy for this condition may have an improved quality of life or attain their goal of successful pregnancy.

Evidence

Medline and Cochrane databases were searched for articles in English and French on subjects related to endometriosis, pelvic pain, and infertility from January 1999 to October 2009 in order to prepare a Canadian consensus guideline on the management of endometriosis.

Values

The quality of evidence was rated with use of the criteria described by the Canadian Task Force on Preventive Health Care. Recommendations for practice were ranked according to the method described by the Task Force. See Table 1.

Benefits, harms, and costs

Implementation of the guideline recommendations will improve the care of women with pain and infertility associated with endometriosis.

Progress in the diagnosis and management of adolescent endometriosis: an opinion

Increasing evidence indicates that early onset endometriosis (EOE), starting around menarche or early adolescence, may have an origin different from the adult variant, originating from neonatal uterine bleeding (NUB). This implies seeding of naïve endometrial progenitor cells into the pelvic cavity with NUB; these can then activate around thelarche. It has its own pathophysiology, symptomatology and risk factors, warranting critical management re-evaluation. It can also be progressive, endangering future reproductive capacity. This variant seems to be characterized by the presence of ovarian endometrioma. Today, the diagnosis of endometriosis in young patients is often delayed for years; if rapidly progressive, it can severely affect pelvic organs, even in the absence of serious symptoms. Given the predicament, great attention must be paid to symptomatology that is often non-specific, justifying a search for new, simple, non-invasive markers of increased risk. Better use of modern imaging techniques will aid considerably in screening for the presence of EOE. Traditional laparoscopy should be limited to cases in which imaging gives rise to suspicion of severity and a stepwise, minimally invasive approach should be used, followed by medical treatment to prevent recurrence. In conclusion, EOE represents a condition necessitating early diagnosis and stepwise management, including medical treatment.

Dienogest 2 mg Daily in the Treatment of Adolescents with Clinically Suspected Endometriosis: The VISanne Study to Assess Safety in ADOlescents

STUDY OBJECTIVE

To study the safety and efficacy of dienogest 2 mg in adolescents with suspected endometriosis.

DESIGN

A 52-week, open-label, single-arm study.

SETTING

In 21 study centers, in 6 European countries.

PARTICIPANTS

Adolescents aged 12 to younger than 18 years with clinically suspected or laparoscopically confirmed endometriosis.

INTERVENTIONS

Dienogest 2 mg once daily.

MAIN OUTCOME MEASURES

The primary end point was relative change in lumbar spine (L2-L4) bone mineral density (BMD) measured using dual-energy x-ray absorptiometry. A key secondary end point was change in endometriosis-associated pain assessed using a visual analogue scale.

RESULTS

Of 120 patients screened, 111 comprised the full-analysis set (ie, patients who took ≥1 dose of study drug and had ≥1 post-treatment observation) and 97 (87.4%) completed the study. Mean lumbar BMD at baseline was 1.1046 (SD, 0.1550) g/cm². At the end of dienogest treatment (EOT; defined as at 52 weeks or premature study discontinuation), mean relative change in BMD from baseline was -1.2% (SD, 2.3%; n = 103). Follow-up measurement 6 months after EOT in the subgroup with decreased BMD at EOT (n = 60) showed partial recovery in lumbar BMD (mean change from baseline: -2.3% at EOT, -0.6% 6 months after EOT). Mean endometriosis-associated pain score was 64.3 (SD, 19.1) mm at baseline and decreased to 9.0 (SD, 13.9) mm by week 48.

CONCLUSION

In adolescents with suspected endometriosis, dienogest 2 mg for 52 weeks was associated with a decrease in lumbar BMD, followed by partial recovery after treatment discontinuation. Endometriosis-associated pain was substantially reduced during treatment. Because bone accretion is critical during adolescence, results of the VISanne study to assess safety in ADOlescents (VISADO) study highlights the need for tailored treatment in this population, taking into account the expected efficacy on endometriosis-associated pain and an individual's risk factors for osteoporosis.

Cancer-Associated Mutations in Endometriosis without Cancer

BACKGROUND

Endometriosis, defined as the presence of ectopic endometrial stroma and epithelium, affects approximately 10% of reproductive-age women and can cause pelvic pain and infertility. Endometriotic lesions are considered to be benign inflammatory lesions but have cancerlike features such as local invasion and resistance to apoptosis.

METHODS

We analyzed deeply infiltrating endometriotic lesions from 27 patients by means of exomewide sequencing (24 patients) or cancer-driver targeted sequencing (3 patients). Mutations were validated with the use of digital genomic methods in microdissected epithelium and stroma. Epithelial and stromal components of lesions from an additional 12 patients were analyzed by means of a droplet digital polymerase-chain-reaction (PCR) assay for recurrent activating KRAS mutations.

RESULTS

Exome sequencing revealed somatic mutations in 19 of 24 patients (79%). Five patients harbored known cancer driver mutations in ARID1A, PIK3CA, KRAS, or PPP2R1A, which were validated by Safe-Sequencing System or immunohistochemical analysis. The likelihood of driver genes being affected at this rate in the absence of selection was estimated at P=0.001 (binomial test). Targeted sequencing and a droplet digital PCR assay identified KRAS mutations in 2 of 3 patients and 3 of 12 patients, respectively, with mutations in the epithelium but not the stroma. One patient harbored two different KRAS mutations, c.35G→T and c.35G→C, and another carried identical KRAS c.35G→A mutations in three distinct lesions.

CONCLUSIONS

We found that lesions in deep infiltrating endometriosis, which are associated with virtually no risk of malignant transformation, harbor somatic cancer driver mutations. Ten of 39 deep infiltrating lesions (26%) carried driver mutations; all the tested somatic mutations appeared to be confined to the epithelial compartment of endometriotic lesions.

Recurrence of Ovarian Endometrioma in Adolescents after Conservative, Laparoscopic Cyst Enucleation

STUDY OBJECTIVE

To evaluate the cumulative recurrence rate of endometriomas after a laparoscopic endometriotic cyst enucleation in adolescents and to find the factors associated with recurrence.

DESIGN

A multicenter retrospective cohort study.

SETTING

Three university hospitals.

PARTICIPANTS

One hundred five patients surgically treated with laparoscopic enucleation of endometriotic cysts younger than 20 years of age were selected.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

Endometrioma recurrence was considered when transvaginal or transrectal sonography indicated a cystic mass with a diameter of 20 mm or greater. Recurrence rate of endometrioma and median time to recurrence were evaluated.

RESULTS

In total, 105 patients were followed for 47.3 (±44.3) months (range, 3-161 months). Seventeen patients (16.2%) experienced recurrence after the first-line surgery and 8 patients (7%) underwent a second surgery. The median time to recurrence was 53.0 (±8.5) months (range, 8-111 months). Using Kaplan-Meier method, the cumulative recurrence rates of endometrioma per patient at 24, 36, 60, and 96 months after the first-line surgery were 6.4%, 10%, 19.9% and 30.9%, respectively. Surgical characteristics, such as the diameter of the cyst, revised American Society for Reproductive Medicine stage, unilateral or bilateral involvement, and coexistence of deep endometriosis were not associated with recurrence in this age group.

CONCLUSION

Although the short-term recurrence rate in adolescents after first-line surgery is relatively low, the recurrence rate appears to be higher according to the follow-up duration. Long-term and continuous follow-up is needed for patients who have undergone surgical treatment for endometriosis in the adolescent period.

Molecular and cellular impact of Psoriasin (S100A7) on the healing of human wounds

Psoriasin, which is also known as S100A7, is a member of the S100 protein family, a group of calcium-responsive signalling proteins. Psoriasin expression remains high in patients with psoriasis, whereas it is downregulated in patients with invasive breast carcinoma. This observation suggests that this protein may be a notable marker of keratinocyte function and differentiation during wound healing. The aim of the present study was to determine the cellular impact of Psoriasin in keratinocytes, which are the primary cell type associated with wound healing. Psoriasin expression in wound tissues was examined using reverse transcription-quantitative polymerase chain reaction and immunochemical staining. Knockdown of Psoriasin in HaCaT cells was performed using anti-Psoriasin ribozyme transgenes and the effect on growth, adhesion and migration of keratinocytes was subsequently determined using in vitro cellular functional assays. Psoriasin expression is upregulated in wounds, particularly at the wound edges. The present study demonstrated that Psoriasin is expressed in keratinocytes and is a fundamental regulator of keratinocyte migration. Significant increases in the rate of keratinocyte adhesion, migration and growth were observed in Psoriasin-deficient cells (P<0.01 vs. control). Application of small inhibitors identified the potential association of neural Wiskott-Aldrich syndrome protein, focal adhesion primase and rho-associated protein kinase signalling pathways with Psoriasin-regulated cell adhesion and motility. In conclusion, Psoriasin serves an important role in the wound healing process, suggesting that it may be utilized as a potential wound healing biomarker.

Research Priorities for Endometriosis

The 3rd International Consensus Workshop on Research Priorities in Endometriosis was held in São Paulo on May 4, 2014, following the 12th World Congress on Endometriosis. The workshop was attended by 60 participants from 19 countries and was divided into 5 main sessions covering pathogenesis/pathophysiology, symptoms, diagnosis/classification/prognosis, disease/symptom management, and research policy. This research priorities consensus statement builds on earlier efforts to develop research directions for endometriosis. Of the 56 research recommendations from the 2011 meeting in Montpellier, a total of 41 remained unchanged, 13 were updated, and 2 were deemed to be completed. Fifty-three new research recommendations were made at the 2014 meeting in Sao Paulo, which in addition to the 13 updated recommendations resulted in a total of 66 new recommendations for research. The research recommendations published herein, as well as those from the 2 previous papers from international consensus workshops, are an attempt to promote high-quality research in endometriosis by identifying and agreeing on key issues that require investigation. New areas included in the 2014 recommendations include infertility, patient stratification, and research in emerging nations, in addition to an increased focus on translational research. A revised and updated set of research priorities that builds on this document will be developed at the 13th World Congress on Endometriosis to be held on May 17-20, 2017, in Vancouver, British Columbia, Canada.

Endometriosis in Adolescents: A Systematic Review

Introduction

The aim of this manuscript is to present a systematic review of characteristics and management of endometriosis in adolescents in order to gain some relevant insight into the most appropriate clinical management of the disease.

Methods

The literature review was done using electronic database PubMed focusing on the terms ‘adolescents’, ‘endometriosis’, ‘teenagers’, ‘pain’, ‘infertility’, ‘quality of life’, ‘medical’ and ‘surgical management’ from 1980 onward and was limited to articles in English. Articles were only included if they reported original relevant research.

Results

The 24 studies selected for review included 1148 adolescents with laparoscopic proven endometriosis. The diagnosis of endometriosis was histologically confirmed in 39.02% (448/1148) of cases. The results from trials have been tabulated and main results presented in a question and answer format.

Conclusions

The majority of adolescent girls with chronic pelvic pain not responding to conventional medical therapy have endometriosis (up to 80%). Laparoscopy with biopsy is the only way to diagnose endometriosis in the adolescent population, and depends on recognition of atypical manifestations of the disease. Surgical management (especially by an expert surgeon) has been shown to be beneficial in reducing pain, improving infertility, and preventing progression or recurrence of disease. Postoperative hormonal suppression helps reduce pain symptoms and recurrence of endometriomas, but it does not seem to prevent disease recurrence or progression of peritoneal endometriosis, and has not been shown to improve future fertility. Postoperative suppression until pregnancy is based on expert opinion only. There is a need for good quality properly randomized trials.

Current methods for the management of endometriosis in adolescent patients

Endometriosis is increasingly recognized as a challenging problem of both diagnosis and management in adolescent gynecology. Areas covered: This special report summarizes the current practices in the evaluation and management of endometriosis in adolescent patients. Expert commentary: We recommend prompt recognition and treatment of endometriosis whenever possible. Management should begin with empiric treatment with NSAIDS and hormonal therapy if complaints of pain interfering with daily activities are elicited. If a patient fails medical therapy after three to six months, surgical intervention is warranted by a clinician experienced in operating in this age range and familiar with the appearance of endometriosis in this age range.

Characteristics of the menstrual cycle in 13-year-old Flemish girls and the impact of menstrual symptoms on social life

This study aimed to investigate the characteristics of symptoms related to the menstrual cycle and their impact on social activities in young teenage girls. Between March and June 2009, all girls born in 1996 who were residents of eight regions in Flanders (Belgium) received a semi-structured questionnaire, including questions about the age of menarche, characteristics of the menstrual cycle, and its impact on social activities. Participants were 792 13-year-old girls (15.7 % of the target population). Out of 363 (47.2 % of participants) postmenarcheal girls, 41.6 % (95 % confidence interval (CI) 36.4-47.0 %) reported painful menstruations. The proportion of girls with painful menstrual periods decreased approximately 16 % with each year the age at menarche increased (relative risk (RR) = 0.84; 0.73-0.98; p < 0.05) and was positively correlated with the amount of blood loss (RR = 0.33; 0.16-0.67; p < 0.05 when little and 1.85; 1.49-2.31; p < 0.001 when abundant, compared to average). One in four (25.4 %) postmenarcheal girls indicated a negative impact of menstruation on social activities, but this proportion was significantly higher in girls who experienced menstruation as painful (41.3 %) compared to those who did not (14.2 %).

CONCLUSION

Early menstrual complaints are common in young adolescent girls and the likelihood of pain increased significantly with lower menarcheal age. What is Known? • Menstrual cycle-related symptoms may negatively interfere with school absence and social activities. • Early menarche and severe dysmenorrhea are correlated with endometriosis. What is New? • In this large population-based study on the characteristics of the menstrual cycle in young teenage girls at or shortly after menarche, painful menstruation was highly prevalent (41.7 %), but related school absenteeism was low (3.2 %). The likelihood of pain increased significantly with lower menarcheal age. • The findings support the need for a systematic evaluation of the characteristics of the menstrual cycle shortly after menarche.

Prevalence of Pain Symptoms Suggestive of Endometriosis Among Finnish Adolescent Girls (TEENMAPS Study)

STUDY OBJECTIVE

To evaluate the prevalence of pain symptoms suggestive of endometriosis among adolescent girls aged 15-19 years.

DESIGN

Cross-sectional study.

SETTING

University hospital.

PARTICIPANTS

Adolescent girls aged 15-19 years attending elementary school, high school, or vocational institute at 3 cities in Southwest Finland in 2010-2011.

INTERVENTIONS

The school nurses distributed a detailed questionnaire to 2582 girls who were attending school at the time of the study. Completion of the questionnaire was voluntary and anonymous.

MAIN OUTCOME MEASURES

Prevalence and severity of dysmenorrhea, acyclic abdominal pain, dyspareunia, dyschezia, and dysuria. Severity was evaluated with an 11-point numerical rating scale (NRS).

RESULTS

A total of 1103 eligible answers were analyzed. The prevalence of dysmenorrhea was 68% (738/1092) with mean NRS of 7.0 (SD = 2.0). Acyclic abdominal pain, dyspareunia, dyschezia, and dysuria were less frequent (19% [207/1085], 12% [53/458], 8% [87/1088] and 5% [50/1084], respectively). The prevalence of severe dysmenorrhea (NRS 8-10) was 33% (355/1089). Severe dysmenorrhea was associated with increased risk of concurrent acyclic abdominal pain (odds ratio [OR] = 2.7; 95% confidence interval [CI], 2.0-3.6), dyschezia (OR = 2.5; 95% CI, 1.6-3.9), and regular absenteeism from school or hobbies (OR = 10.0; 95% CI, 4.2-23.6). Using different criteria, 2%-10% (21-106/1103) of all girls could be identified as having symptoms suggestive of endometriosis. Five percent of girls (n = 53/1103) had severe dysmenorrhea, used oral contraceptive pills, and reported inadequate relief from pain medication.

CONCLUSION

One-third (355/1089) of 15- to 19-year-old girls had severe menstrual pain and 14% (49/355) of them were regularly absent from school or hobbies. Five percent of all teenage girls (53/1103) were poor responders to conventional therapy for primary dysmenorrhea.

Endometriosis in adolescents

Background and Objectives:

Women with endometriosis often report onset of symptoms during adolescence; however, the diagnosis of endometriosis is often delayed. The aim of this study was to describe the experience of adolescents who underwent laparoscopy for pelvic pain and were diagnosed with endometriosis: specifically, the symptoms, time from onset of symptoms to correct diagnosis, number and type of medical professionals seen, diagnosis, treatment, and postoperative outcomes.

Methods:

We reviewed a series of 25 females ≤21 years of age with endometriosis diagnosed during laparoscopy for pelvic pain over an 8-year period. These patients were followed up for 1 year after surgery.

Results:

The mean age at the time of surgery was 17.2 (2.4) years (range, 10–21). The most common complaints were dysmenorrhea (64%), menorrhagia (44%), abnormal/irregular uterine bleeding (60%), ≥1 gastrointestinal symptoms (56%), and ≥1 genitourinary symptoms (52%). The mean time from the onset of symptoms until diagnosis was 22.8 (31.0) months (range, 1–132). The median number of physicians who evaluated their pain was 3 (2.3) (range, 1–12). The adolescents had stage I (68%), stage II (20%), and stage III (12%) disease. Atypical endometriosis lesions were most commonly observed during laparoscopy. At 1 year, 64% reported resolved pain, 16% improved pain, 12% continued pain, and 8% recurrent pain.

Conclusions:

Timely referral to a gynecologist experienced with laparoscopic diagnosis and treatment of endometriosis is critical to expedite care for adolescents with pelvic pain. Once the disease is diagnosed and treated, these patients have favorable outcomes with hormonal and nonhormonal therapy.

Adolescent Endometriosis: Report of a Series of 55 Cases With a Focus on Clinical Presentation and Long-Term Issues

STUDY OBJECTIVE

To report the clinical presentation and long-term issues of adolescent endometriosis.

DESIGN

Retrospective cohort study.

SETTING

Single private clinical center, Bordeaux, France.

PATIENTS

Adolescents with a confirmed diagnosis of endometriosis.

INTERVENTIONS

Surgical excision or ablation or lesions performed at laparoscopy.

MEASUREMENTS AND MAIN RESULTS

Fifty-five adolescents, ages from 12 to 19 years (mean age 17.8), who were diagnosed with endometriosis from March 1998 to April 2013 were included in the study. Pain of various types was the leading symptom in all patients, except 2. Twenty-three patients had an adnexal mass identified preoperatively, and 5 had an associated infertility issue at the time of diagnostic laparoscopy. Four patients had an associated genital malformation. Fifty-one percent of the patients had a history of appendectomy. A familial history of endometriosis was reported by 19 patients (34.5%), with a first-degree relative affected in 14 cases (25.45%), and 47.3% of patients were smoking at least 5 cigarettes a day. Superficial implants was encountered in 31 cases (56.4%), endometriomas in 18 cases (32.72%), and deep infiltrating endometriosis (DIE) in 6 cases (10.90%). Sixty percent of patients were scored as stages I to II and 40% as stages III to IV. Five patients were lost to follow-up, and 37 had a follow-up ranging from 36 to 315 months (mean follow-up 125.5 months). Among the 50 patients not lost to follow-up, 13 (26%) had either no pain, or improved and had acceptable pain with medical treatment. Seventeen patients of the 50 adolescents not lost to follow-up (34%) underwent a repeat laparoscopy. A subsequent laparoscopic and/or magnetic resonance imaging scan was performed in 35 patients because of persistent pain. Among these, there was 12 endometriomas (7 recurrences) and 12 DIEs (3 recurrences), giving recurrence rates for endometriomas and DIEs of 36.84% and 50%, respectively. During the study, 18 patients wished to have a child. Thirteen had a delivery (72.2%), and 9 pregnancies occurred in patients who initially presented with stage I to II endometriosis. Of the 11 patients who had subfertility, 6 successfully conceived (54.5%).

CONCLUSIONS

Adolescent endometriosis is not a rare condition. In our study a familial history was reported in more than one-third of patients. Among those patients treated for DIE, there was a trend for higher rates of recurrences (symptoms or lesions) that required repeat laparoscopy. However, the impact on subsequent fertility appeared to have been limited.

Diagnostic Challenges in a Young Woman with Endometriosis: The Value of Excision

Objective

The aim of this report is to highlight the value of excision when treating and diagnosing endometriosis, as well as present an unusual case of concomitant endometriosis and pelvic malignancy in a young female.

Case Report

In a university hospital referral center, a 24-year-old nulligravid woman with suspected endometriosis had been treated unsuccessfully with empiric therapy for several years. Interventions were preoperative cyclic and continuous combined oral contraceptive pills and a NuvaRing for 2 years. Diagnosis was completed by laparoscopy and histologic evaluation. Surgical debulking by gynecology oncologist was followed by chemotherapy. The main outcome measure was definitive diagnosis via histology.

Results

Histologic diagnosis of endometriosis and concomitant pelvic malignancy with successful surgical excision of both.

Conclusions

When evaluating a patient with chronic pelvic pain, it is necessary to have a high degree of suspicion for endometriosis. Early surgical and histologic evaluation is imperative for definitive diagnosis. An added benefit of histologic diagnosis is the opportunity to assess for malignancy.

Advanced stage endometriosis in adolescents and young women

STUDY OBJECTIVE

To describe the prevalence and characteristics of advanced stage endometriosis in adolescents and young women treated in a tertiary referral center.

DESIGN

Retrospective cohort.

SETTING

Tertiary referral center.

PATIENTS AND INTERVENTIONS

86 adolescents and young women (≤22 y) who underwent surgery for endometriosis. The operative reports were reviewed for endometriosis stage, surgical findings, surgical procedures, and pathology.

MAIN OUTCOME MEASURES

Endometriosis stage reported according to the revised American Fertility Society classification.

RESULTS

Early stage endometriosis (stage I or II) was found in 66 (76%) and advanced stage endometriosis (stage III or IV) in 20 (23%). The surgical findings in the 20 patients with advanced stage endometriosis included ovarian endometriomas in 14 cases, rectovaginal nodule in 1 case, and diaphragmatic and pulmonary endometriosis in 1 case. Women with advanced stage endometriosis were found to be slightly older at time of diagnosis than those with early stage disease (mean age 20.4 ± 1.4 y vs 18.7 ± 2.2 y respectively, P < .001).

CONCLUSION

In adolescents and young women with endometriosis, advanced stage disease is not uncommon. The main presentation of advanced stage endometriosis in this age group is ovarian endometriomas rather than extensive peritoneal or adhesive disease.

Endometriosis and the Enigmatic Question of Progression

Aims

The aim of this study was to identify whether endometriosis is a progressive disease with age, and to review the literature on this topic.

Material and methods

The incidence of endometriosis in a cohort of 500 women who underwent laparoscopy between 2003 and 2013 in the Greenville Health System, in South Carolina, United States, was reviewed. The search of the world literature on progression of endometriosis was limited to 1980 and beyond.

Results

The correlation between stage of endometriosis and age was found to be small (r = −0.04; 95% CI, −0.13 to 0.04; p = 0.3; n = 471). The literature search identified 16 studies on adults. Progression of endometriosis findings at laparoscopy occurred in 31% of the cases with follow-up (n = 162).

Conclusions

Endometriosis of minimal or mild American Society for Reproductive Medicine (rASRM) classification stage is equally likely to be present in women of all ages; similarly, endometriosis in its severe form is not age-dependent.

The patient-centeredness of endometriosis care and targets for improvement: a systematic review

BACKGROUND

Endometriosis is a prevalent condition compromising physical and psychosocial health and thus requiring patient-centered care, which is guided by patients' values. This study aimed to find out what the patient's perspective on endometriosis care is and how the patient-centeredness of endometriosis care can be improved.

METHODS

Electronic databases were searched systematically, and study selection was based on eligibility and quality. Study methodology was examined. Specific care aspects valued by patients were organized according to 10 dimensions of patient-centered endometriosis care. Based on patients' assessments of service quality, patient-centered improvement targets and strengths were identified.

RESULTS

Twelve of 20 eligible studies had sufficient quality to be included. Endometriosis patients valued all 10 dimensions of patient-centered endometriosis care. Problematic service quality was reported for all dimensions but 'coordination and integration' and 'involvement of significant others'. Two patient-centered strengths and 29 patient-centered improvement targets were identified. The most frequently reported improvement targets on which studies agreed were 'timely diagnosis' and 'being believed and respected by staff'.

CONCLUSION

Endometriosis patients value patient-centeredness in addition to effectiveness and safety of care, and its 10 dimensions require attention in clinical practice. Research into the assessment and improvement of patient-centered endometriosis care is required.

Adolescent Endometriosis: Review of Clinical Presentation and Long-Term Issues

Endometriosis may affect adolescent girls. The scientific literature on endometriosis in adolescents is limited, and many aspects are still uncertain despite a growing number of related reports. The prevalence of endometriosis in adolescents is unknown, but in selected groups of patients undergoing laparoscopy, it has been found to be higher than 50%. The physiopathology of adolescent endometriosis has not been specifically shown. However, the presence of a family history and associated genital malformations are more frequently identified in adolescents with endometriosis. The clinical presentation of the disease in adolescents has been assessed by numerous prospective and retrospective studies, and the risk factors for the development of endometriosis are well-known. The recommended diagnostic strategy is actually well-characterized, even if an early diagnosis is hardly ever made. The therapeutic management is also more consensual, but not definitive because of a lack of prospective studies evaluating either short- or long-term results and the impact on the natural history of the disease. Finally, the long-term sequelae are still a burden, and many questions are unanswered, despite new insights provided by a few recent reports evaluating the progression of the disease and its effects on subsequent fertility. Further studies are needed to better assess these issues.

Endometriosis: a life cycle approach?

To improve the still fragmented understanding of endometriosis, a life cycle approach was adopted that revealed unexpected aspects of the natural history of the disease throughout a woman's life. Three age-related stages of endometriosis are distinguished. In premenarcheal and adolescent endometriosis, 2 types can be distinguished: a classic form that can occur before menarche, and a congenital obstructive form that is caused by uterine anomaly and outflow obstruction. The lesions include superficial peritoneal implants, but adhesions and endometrioma can also occur. It is suggested that premenarcheal and possibly adolescent endometriosis develop by activation of resting stem cells shed at the time of neonatal retrograde uterine bleeding. In the adult, endometriosis can be related to uterine preconditioning by cyclic menstruations acting as a priming mechanism for deep placentation. In adult life, the typical lesions are peritoneal, ovarian, and deep or adenomyotic endometriosis. More recently, endometriosis has been associated with endometrial dysfunction and myometrial junctional zone hyperplasia. These uterine changes can be linked with some major obstetrical syndromes. In postmenopause, endometriosis can develop or be reactivated both in the presence or absence of exogenous estrogens and can spread to a variety of organs and structures causing constrictive lesions.
