Failed diagnostic hysteroscopy: Analysis of 62 cases

Preoperative promestriene for hysteroscopy: a randomized clinical trial

OBJECTIVE

Intraoperative complications of hysteroscopy, such as the creation of a false passage, cervix dilatation failure, and uterine perforation, may require suspension of the procedure. Some patients refuse a new procedure, which delays the diagnosis of a possible serious uterine pathology. For this reason, it is essential to develop strategies to increase the success rate of hysteroscopy. Some authors suggest preoperative use of topical estrogen for postmenopausal patients. This strategy is common in clinical practice, but studies demonstrating its effectiveness are scarce. The aim of this study was to evaluate the effect of cervical preparation with promestriene on the incidence of complications in postmenopausal women undergoing surgical hysteroscopy.

METHODS

This is a double-blind clinical trial involving 37 postmenopausal patients undergoing surgical hysteroscopy. Participants used promestriene or placebo vaginally daily for 2 weeks and then twice a week for another 2 weeks until surgery.

RESULTS

There were 2 out of 14 (14.3%) participants with complications in the promestriene group and 4 out of 23 (17.4%) participants in the placebo group (p=0.593). The complications were difficult cervical dilation, cervical laceration, and vaginal laceration.

CONCLUSION

Cervical preparation with promestriene did not reduce intraoperative complications in postmenopausal patients undergoing surgical hysteroscopy.

Exploring Surgical Strategies for Uterine Fibroid Treatment: A Comprehensive Review of Literature on Open and Minimally Invasive Approaches

Background and Objectives: Uterine myomas represent one of the most prevalent pathologies affecting the female population. These benign neoplasms originate from the smooth muscular cells of the uterus, and they can be either single or multiple. Often associated with debilitating symptoms such as pelvic heaviness, pain, constipation, and urinary dysfunctions, the surgical management of myomectomy exhibits considerable variability. This diversity in approaches is influenced by factors such as the number and size of myomas, the patient's age, and overall clinical conditions. This study aims to elucidate and compare the advantages and disadvantages of different surgical approaches, specifically endoscopic procedures versus open surgery, providing valuable insights for clinical decision making. Materials and Methods: A comprehensive bibliographic search spanning from 2013 to 2023 was systematically conducted across databases including Medline, Embase, the Cochrane Database of Systematic Reviews, and ClinicalTrials.gov. The search utilized keywords such as "myomectomy laparoscopic and open", "myomectomy open and minimally invasive", "myomectomy open and laparoscopic", and "myomectomy open vs. laparoscopic." The research methodology, along with predetermined inclusion and exclusion criteria, was established prior to the search, ensuring a systematic and rigorous approach. Subsequently, data analysis was carried out. Results: Following the study selection process, 25 articles met the eligibility criteria for inclusion in this analysis. The average numbers of myomas were 3.7 (ranging from 1 to 13.7) and 5.4 (ranging from 1 to 13.5) for the minimally invasive surgery and open surgery groups, respectively. In terms of myoma size, the total averages across studies were 7 cm (ranging from 4.8 to 14) for the minimally invasive group and 8 cm (ranging from 3.9 to 11.2) for the open surgery group. The average pregnancy and delivery rates were 29.7% (ranging from 1.8 to 100) for the minimally invasive group and 28.5% (ranging from 1.8 to 100) for the open surgery group. Regarding complications, the average rate was 14.2% (ranging from 0 to 50) for the endoscopic group and 22.3% (ranging from 0 to 60.3) for the laparotomic group. Conclusions: In conclusion, a critical factor influencing the choice of surgical approach is primarily the size and quantity of fibroids. The mini-laparotomic approach emerges as a viable alternative to endoscopy, demonstrating favorable surgical outcomes and aesthetic results. Interestingly, the type of surgical procedure appears to have no significant impact on the pregnancy rate.

Patients' Use of Virtual Reality Technology for Pain Reduction during Outpatient Hysteroscopy: A Meta-analysis of Randomized Controlled Trials

OBJECTIVE

To summarize evidence from randomized controlled trials (RCTs) on the effectiveness of virtual reality technology (VRT), as used by patients, for reducing pain during outpatient hysteroscopy.

DATA SOURCES

Electronic databases and clinical registers were searched until June 21, 2023. The review protocol was registered in PROSPERO before the data extraction (CRD42023434340).

METHODS OF STUDY SELECTION

We included RCTs of patients receiving VRT compared with controls receiving routine care during outpatient hysteroscopy.

TABULATION, INTEGRATION, AND RESULTS

The primary outcome was average pain during hysteroscopy. Pooled results were expressed as mean differences (MDs) with 95% confidence interval (CI). Sources of heterogeneity were investigated through sensitivity and subgroups analysis. Five RCTs were included (435 participants). The comparison between the intervention and control groups showed a borderline difference in perceived pain during hysteroscopy (MD -0.88, 95% CI -1.77 to 0.01). Subgroup analysis based on the type of VRT (active or passive) indicated that active VRT potentially reduced the perception of pain (MD -1.42, 95% CI -2.21 to -0.62), whereas passive VRT had no effect (MD -0.06, 95% CI -1.15 to 1.03).

CONCLUSION

Patients' use of active VRT may be associated with a reduction in pain during outpatient hysteroscopy (evidence Grading of Recommendations Assessment, Development, and Evaluation 2/4). Future research should focus on conducting methodologically robust studies with larger sample sizes and more homogeneous populations.

Hysteroscopic Findings and Operative Treatment: All at Once?

Hysteroscopy is considered not only a diagnostic instrument but also a therapeutic tool for many uterine pathologies. In the early 1990s, advances in technology and techniques made hysteroscopy less painful and invasive, allowing to increase in the number of gynecological procedures performed in an ambulatory setting without significant patient discomfort and with potentially significant cost savings. This is the so-called "office hysteroscopy" or "see-and-treat hysteroscopy", whose spread has permitted the decrease of the number of procedures performed in the operating room with the benefit of obviating the need for anesthesia and dilatation of the cervical canal.

Management of a giant uterine smooth muscle tumor of uncertain malignant potential in a 32-year-old woman: case report and review of the literature

Uterine smooth muscle tumors of uncertain malignant potential (STUMP) represent a group of rare uterine smooth muscle tumors not diagnosed unequivocally as benign or malignant. To data, diagnostic criteria, malignant potential, surgical management, and follow-up of these neoplasms remain controversial. Considering that STUMP and leiomyoma are not significantly different in terms of clinical presentation and preoperative sonographic characteristics, it might be difficult to distinguish between the two affections prior to pathological confirmation at surgery. All cases should be managed by multidisciplinary tumor teams and patients' follow-up should comprise consultation with a gynecologic oncologist and a close surveillance because of the possibility of recurrence or metastasis. We present the case of a 32-year-old nulliparous woman admitted to our gynecology clinic. She was asymptomatic and only complained an increase in abdominal volume started during the past 6 months. A transabdominal and transvaginal pelvic ultrasound revealed a large heterogeneous tumor mass measuring 190×163 mm, color score 2, expanded in the left iliac fossa, suspected for benign uterine myoma. Subsequent magnetic resonance imaging confirmed a large pelvic-abdominal tumor located near the left posterior-lateral uterine wall with areas of necrosis, suggestive of subserosal leiomyoma with cystic degeneration. The patient underwent a median longitudinal laparotomy for excision of the pelvic mass. The patient was normally discharged five days after surgery in good health conditions. The final histological examination was compatible with STUMP. At present, the patient has had no relapses or metastases and she is undergoing follow-up.

Does “no-touch” technique hysteroscopy increase the risk of infection?

Objective:

Today, thanks to its many advantages, hysteroscopy with a vaginoscopic approach (no-touch) is increasingly being used more in outpatient diagnoses and treatments. However, there are concerns that the “no-touch” technique increases ascending genital tract infections since a speculum is not inserted, and disinfection of the cervix cannot achieve.

Materials and Methods:

Between 2011 and 2017, 302 patients who underwent office hysteroscopy with the vaginoscopic approach (group 1) and 254 patients who underwent hysteroscopy with the standard method under anesthesia in the operating room (group 2) were compared in terms of early complications (within two weeks postoperatively). The primary outcome was early postoperative infection, and the secondary outcome was other early complications, such as bleeding and rupture.

Results:

In this study, the success rate of hysteroscopy with the vaginoscopic approach was 96.4%. According to the visual analog scale scoring system, 88.7% of the patients described mild-to-moderate pain. When group 1 and 2 were compared in terms of postoperative infection (3% and 2.4%, respectively) and other early complication rates (0% and 0.8%, respectively), no statistically significant difference was found (p>0.05).

Conclusion:

Hysteroscopy with a vaginoscopic approach continues to be the gold standard method that is safe and well-tolerated by patients.

Diagnostic office hysteroscopy; why is it still painful procedure despite the surgical experience and mini-hysteroscope?

AIM

To evaluate the effect of cervical canal features on pain during outpatient hysteroscopy performed by experienced surgeons using mini-hysteroscope.

METHODS

A prospective observational study was conducted on 303 women undergoing diagnostic hysteroscopy without anesthesia. Pain intensity was evaluated using the visual analog scale (VAS) when the cervical canal was passed. The patients were divided into two groups according to the VAS score: painless or mild pain (VAS <4) and moderate or severe pain (VAS ≥ 4). The relationship between cervical canal characteristics (length, version, and flexion positions, history of cervical intervention, stenosis, synechiae), obstetric and gynecological history, preoperative anxiety level, procedure duration, and pain intensity was examined.

RESULTS

Moderate pain (4 ≤ VAS < 7) was observed in 38% of patients (n = 117) and 14 patients (5%) experienced severe pain (VAS ≥ 7). In multivariate analysis, nulliparity (p = 0.01; OR, 4.6; 95% CI, 1.7-13.2), postmenopausal state (p = 0.02; OR, 2.2; 95% CI, 1.2-4.3), excessive flexion of the cervix and retroverted uterus (p <0.001; OR, 4.1; 95% CI, 2.0-8.5) were identified as risk factors for a painful procedure. Diagnostic hysteroscopy was successful in 98% of the patients. The pain was the primary cause of the failed hysteroscopy.

CONCLUSION

In addition to nulliparity and postmenopausal status, unfavorable features of the cervical canal, such as the excessive flexion position of the cervix and uterine retroversion are significant causes of pain during outpatient hysteroscopy.

Immersive virtual reality as tool to reduce anxiety during embryo transfer

The use of Virtual Reality (VR) has gained wide acceptance in several scientific fields. It represents an innovative technological tool providing the experience to be immersed in a non-physical world putting on head-mounted displays that surround the users with images and sounds. To date, VR has been mainly employed in the healthcare sector for educational aims, in order to provide the learners with a new method of delivering simulations. However, its application to real clinical practice has recently generated beneficial effects for patients, especially for those who experience symptoms of psychological burden. Infertile couples often struggle with anxiety and depression which have a strong impact on life quality. Furthermore, the perspective to undergo long treatments with uncertain results and an history of failed attempts may contribute to enhance patients' negative feelings during In Vitro Fertilization (IVF) cycles until Embryo Transfer (ET). The role of VR in reducing pain and anxiety during outpatient hysteroscopy, hysterosalpingography and oocytes retrieval, has been recently investigated with satisfactory results in terms of reducing pain and anxiety levels. However, to date, inconclusive outcomes have been reported on pregnancy rate. Our study would discuss the existent literature on VR applied to current medical practice and infertility, proposing its beneficial impact on women anxiety during IVF cycle with ET.

Hysteroscopy as An Investigational Operative Procedure in Primary and Secondary Infertility: A Systematic Review

Background

The aim of this study is to review current indications to diagnostic and/or operative hysteroscopy in primary and secondary infertility, as well as to determine its efficacy in improving fertility.

Materials and Methods

We gathered available evidence about the role of hysteroscopy in the management of vari- ous infertility conditions. Literature from 2000 to 2020 that pertained to this topic were retrieved and appropriately selected.

Results

Hysteroscopy does not appear as a first line diagnostic procedure for every clinical scenario. However, its di- agnostic sensitivity and specificity in assessing intrauterine pathology is superior to all other non-invasive techniques, such as saline infusion/gel instillation sonography (SIS/GIS), transvaginal sonography (TVS) and hysterosalpingog- raphy (HSG). Hysteroscopy allows not only a satisfactory evaluation of the uterine cavity but also, the eventual treat- ment of endocavitary pathologies that may affect fertility both in spontaneous and assisted reproductive technology (ART) cycles.

Conclusion

Hysteroscopy, due to its diagnostic and therapeutic potential, should be regarded as a necessary step in infertility management. However, in case of suspected uterine malformation, hysteroscopy should be integrated with other tests [three-dimensional (3D) ultrasound or magnetic resonance imaging (MRI)] for diagnostic confirmation.

Office hysteroscopy in pre- and post-menopausal women: a predictive model

OBJECTIVES

To assess the variables associated with success of office hysteroscopy (OH) in pre-menopausal and post-menopausal women and to develop a clinical model for predicting the outcome of OH.

METHODS

This is a retrospective cohort study of consecutive patients (n = 3181) referred for an OH to a tertiary care university hospital between January 2018 and March 2020. Multivariate logistic regression analysis was used to investigate the variables for predicting the success of OH in all patients and in pre-menopausal and in post-menopausal patients separately. The logistic regression analysis of each variable was applied to develop a predictive model.

RESULTS

The overall success rate of the procedure was 92.2%; 95.4% in pre-menopausal women and 87.6% in post-menopausal women. In the general population, independent predictors of procedure success were previous vaginally delivery and hysteroscopy, while previous cervical or uterine surgery were associated with incomplete OH. In the pre-menopausal group, the independent predictors of failure were treatment with GnRH, estroprogestins and infertility. In 89% of cases, our developed model was able to predict whether an OH would be successful in a particular patient. ROC analysis showed an area under the curve of 0.8746 (95% CI: 0.85354-0.89557).

CONCLUSIONS

The present study demonstrates the development of a simple and reliable clinical model for the identification of both pre-menopausal and menopausal patients with a high chance of OH success.

Hysteroscopic approach to uterine cervical canal stenosis

Cervical stenosis is defined as an adhesion process of variable degree, producing narrowing, distortion, or complete obliteration of the cervix. Several techniques have been defined to access to the uterine cavity and nowadays hysteroscopy seems to be the best option. In this manuscript, we review all the hysteroscopic modalities to overcome a cervical stenosis and access to the uterine cavity.
