Global recommendations on adhesion prophylaxis in gynaecological laparoscopic surgery.

Adhesions are recognised as one of the most common complications of abdominal surgery; their diagnosis and prevention remains a significant unmet need in surgical therapy, affecting negatively a patient's quality of life and healthcare budgets. In addition, postoperative pelvic adhesions pose a high risk of reduced fertility in women of childbearing age. These 2023 Global Recommendations on Adhesion Prevention in Gynaecological Laparoscopic Surgery provide agreed-upon statements to guide clinical practice, with the ultimate goal of improving patient outcomes.

European Society for Gynaecological Endoscopy (ESGE) Good Practice Recommendations on surgical techniques for removal of fibroids: part 1 abdominal (laparoscopic and open) myomectomy.

Uterine fibroids are the most common benign tumours of the female reproductive tract and can cause a range of symptoms including abnormal uterine bleeding, pain, pressure symptoms and subfertility. Surgery may be required for some symptomatic fibroids via abdominal or transvaginal routes. The European Society for Gynaecological Endoscopy Uterine Fibroids Working Group developed recommendations based on the best available evidence and expert opinion for the surgical treatment of uterine fibroids. In this first part of the recommendations, abdominal approaches to surgical treatment of fibroids including laparoscopic, robot- assisted and open myomectomy are described.

Structured hysteroscopic examination of uterine niches: a modified Delphi procedure.

Background: Uterine niches in the Caesarean section scar are seen in approximately half of women with a history of caesarean delivery. Whilst a structured ultrasound assessment of caesarean defects has been described, there is no consensus on a structured hysteroscopic evaluation. Objectives: To propose a methodology for a structured hysteroscopic evaluation of uterine niches. Materials and Methods: We conducted a modified Delphi procedure, including two online rounds and two face-to-face meetings of the members of the ESGE Uterine Niches Working Group. The taskforce members have extensive experience in hysteroscopic niche evaluation. The consensus was predefined as a Rate of Agreement of at least 75%. Results: Thirteen experts participated in this modified Delphi procedure. There was consensus on the need for a standardised methodology and the hysteroscopic definition of a niche as any indentation in the myometrium at the site of a previous CS. There was consensus that a hysteroscopic evaluation of a niche must be combined with ultrasound to measure the residual myometrial thickness. In addition, it was agreed that niches should be subclassified as 'simple', 'simple with one branch', or 'complex'. There was consensus that the following items should be described during a hysteroscopic niche evaluation: the number of niches, the size in relation to the size of cervical canal, the presence of polyps, crypts, cysts, fibrotic tissue, blood, mucus, placental remnants, a dynamic valve, the appearance of the endometrium, the number of blood vessels and bleeding from blood vessels within the defect. Conclusion: Using a modified Delphi procedure with international experts, consensus was achieved on the hysteroscopic evaluation and classification of niches in the uterine caesarean section scar. What is new?: A structured registration form was developed to aid consistency in hysteroscopic niche reporting.

An age-related nomogram for antral follicle count: an observational study of 3821 women.

RESEARCH QUESTION: What is the relationship between antral follicle count (AFC) and chronological age, and what are the expected values for AFC? DESIGN: This was a retrospective cohort study at a specialist gynaecological ultrasound centre in London, UK. Women presenting to a gynaecology diagnostic unit for investigation of symptoms or routine check-up, and undergoing transvaginal ultrasound (TVUS) examinations, between 1 January 2017 and 22 September 2022 were included in this study. RESULTS: In total, 8821 TVUS records from 7573 patients were analysed. The relationship between AFC and age was estimated to develop an AFC nomogram independent of the stage in the menstrual cycle. AFC corresponding to the 10th, 25th, 50th, 75th and 90th centiles for each patient and age group were calculated. Both nomogram and condition-specific populations displayed a Gaussian relationship between AFC and age. For the nomogram population (scans n = 4256, patients n = 3821), a peak median AFC of 30 was observed between 21-23 years of age. The AFC distribution of the group with previous ovarian cystectomy (scans n = 534, patients n = 443) was found to be significantly different compared with the nomogram population (P < 0.0001). However, the same did not hold true for those on hormonal contraception (scans n = 566, patients n = 534) (P = 0.43). CONCLUSIONS: An AFC nomogram reporting median and interquartile values for AFC by chronological age across the reproductive years was developed. This is a useful tool for providing counselling for those undergoing ovarian reserve assessments, and can be taken any time in the menstrual cycle, including in women on hormonal contraceptives or who have undergone previous ovarian cystectomy.

Horizons in Endometriosis: Proceedings of the Montreux Reproductive Summit, 14-15 July 2023.

Endometriosis is a complex and chronic gynaecological disorder that affects millions of women worldwide, leading to significant morbidity and impacting reproductive health. This condition affects up to 10% of women of reproductive age and is characterised by the presence of endometrial-like tissue outside the uterus, potentially leading to symptoms such as chronic pelvic pain, dysmenorrhoea, dyspareunia, and infertility. The Montreux summit brought a number of experts in this field together to provide a platform for discussion and exchange of ideas. These proceedings summarise the six main topics that were discussed at this summit to shed light on future directions of endometriosis classification, diagnosis, and therapeutical management. The first question addressed the possibility of preventing endometriosis in the future by identifying risk factors, genetic predispositions, and further understanding of the pathophysiology of the condition to develop targeted interventions. The clinical presentation of endometriosis is varied, and the correlation between symptoms severity and disease extent is unclear. While there is currently no universally accepted optimal classification system for endometriosis, several attempts striving towards its optimisation - each with its own advantages and limitations - were discussed. The ideal classification should be able to reconcile disease status based on the various diagnostic tools, and prognosis to guide proper patient tailored management. Regarding diagnosis, we focused on future tools and critically discussed emerging approaches aimed at reducing diagnostic delay. Preserving fertility in endometriosis patients was another debatable aspect of management that was reviewed. Moreover, besides current treatment modalities, potential novel medical therapies that can target underlying mechanisms, provide effective symptom relief, and minimise side effects in endometriotic patients were considered, including hormonal therapies, immunomodulation, and regenerative medicine. Finally, the question of hormonal substitution therapy after radical treatment for endometriosis was debated, weighing the benefits of hormone replacement.

Lessons learnt from the multi-centre LAparoscopic Versus Abdominal hysterectomy (LAVA) randomised controlled trial.

Background: The LAparoscopic Versus Abdominal hysterectomy (LAVA) randomised controlled trial comparing laparoscopic hysterectomy (LH) and abdominal hysterectomy (AH) closed prematurely on the grounds of futility. Here we identify the challenges faced and lessons learnt. Objectives: To explore the views and experiences of clinical/research staff in order to understand how these might act as barriers to trial participation and recruitment. Materials and Methods: Review of the trial progress and collation of the views and experiences of clinical/ research staff on all aspects of the trial. Data were collected from transcribed conversations, email, phone, or video conferencing interactions and analysed descriptively. Main outcome measures: Site set-up milestones, recruitment rates and reasons provided by clinical/research staff for site's declining to participate. Opinions, preferences and experiences of clinicians/researchers and challenges to participation and recruitment. Results: The mean time from initial site contact to opening was 253 days and 68 days to randomise their first participant. 265 patients were screened from 13 sites over 13 months, 154 were eligible, and 75 (59%) were randomised. Of the 53 not randomised, 23 (43%) women preferred LH whilst 6 (11%) preferred AH. The main reasons given for failure to recruit or activate set-up in the 21 sites open or in set-up, were lack of research/ clinical capacity imposed by the COVID-19 pandemic and lack of clinician equipoise. Conclusions: The main reasons for the LAVA trial failure were lack of equipoise amongst surgeons and the adverse impact of the COVID-19 pandemic on clinical/research services. What is new?: Surgeons' preference for laparoscopic hysterectomy is not shared by most patients. Many patients prefer an open hysterectomy to a laparoscopic one.

Excisional endometriosis surgery with hysterectomy and bilateral salpingo-oophorectomy versus excisional endometriosis surgery alone for pelvic pain associated with deep endometriosis.

Background: There is no agreed consensus on the optimal surgical treatment for pain associated with endometriosis. Objectives: To compare improvement in symptoms and quality-of-life in patients undergoing excisional endometriosis surgery (EES) versus EES with hysterectomy and bilateral salpingo-oophorectomy (EES-HBSO). Methods: This study evaluated patients undergoing EES and EES-HBSO at a single endometriosis centre between 2009 and 2019. Data was obtained from the British Society for Gynaecological Endoscopy database. Adenomyosis was assessed by blinded re-analysis of imaging and/or histology data. Main outcome measures: Pain scores (numeric rating scale 0-10) and quality-of-life scores (EQ-VAS) before and after EES and EES-HBSO. Results: We included 120 patients undergoing EES and 100 patients undergoing EES-HBSO. After controlling for baseline characteristics and the presence of adenomyosis, there was greater post-op improvement in non-cyclical pelvic pain amongst patients undergoing EES-HBSO compared to EES alone.The baseline pain scores had improved in the EES-HBSO cohort by 2.106/10 at 6 months (95%CI 0.469-3.742, p=0.012), 2.642/10 at 12 months (95%CI 0.871-4.413, p=0.004), and 2.548/10 at 24 months (95%CI 0.681-4.414, p=0.008), when compared to the EES group. Greater improvement amongst EES-HBSO patients was also seen for dyspareunia, non-cyclical dyschaezia and bladder pain. Patients undergoing EES-HBSO had greater improvement in EQ-VAS, although this was no longer statistically significant after controlling for adenomyosis. Conclusion: EES-HBSO appears to provide greater benefit than EES alone for symptoms including non-cyclical pelvic pain as well as for quality-of-life. Further research is required to determine which patients benefit the most from EES-HBSO, and whether removal of the ovaries, uterus or both is the key to this additional benefit in symptom control.

Endometrial preservation during resection of type II and type III submucosal fibroids.

Background and objectives: Hysteroscopic myomectomy is considered the gold-standard treatment of submucosal fibroids. However, it is associated with disruption of the endometrium which may lead to complications such as intrauterine adhesions and loss of functional endometrium. In this video article we describe a technique to resect Type III and Type II fibroids whilst minimising the loss of overlying endometrium. Materials and methods: We present two patients with type II/III submucosal fibroids with minimal or no intracavity component. The resection technique we demonstrate comprises either making an endometrial incision or making a small opening in the overlying endometrium to expose the fibroid pseudocapsule. Subsequent steps of resection are then performed through this small opening. Thus, complete resection is achieved without further resection of the endometrium. Main outcome measures: Evidence of endometrial healing and absence of intrauterine synechiae on follow up outpatient hysteroscopy or ultrasound scan. Results: Full resection was achieved in both patients with no or minimal loss of overlying endometrium. A follow up outpatient hysteroscopy was performed 8 weeks later in the first patient, demonstrating completely healed uterine cavity. She had a successful conception and delivery following IVF treatment for male factor infertility. The second patient is currently in the process of IVF treatment. Conclusions: Our technique enables endometrial preservation and potentially better reproductive outcomes following resection of type II and type III submucosal fibroids. Larger scale studies are required to elucidate long term outcomes on bigger patient population.

Development of a core outcome set and outcome definitions for studies on uterus-sparing treatments of adenomyosis (COSAR): an international multistakeholder-modified Delphi consensus study.

STUDY QUESTION: What outcomes should be reported in all studies investigating uterus-sparing interventions for treating uterine adenomyosis? SUMMARY ANSWER: We identified 24 specific and 26 generic core outcomes in nine domains. WHAT IS KNOWN ALREADY: Research reporting adenomyosis treatment is not patient-centred and shows wide variation in outcome selection, definition, reporting and measurement of quality. STUDY DESIGN, SIZE, DURATION: An international consensus development process was performed between March and December 2021. Participants in round one were 150 healthcare professionals, 17 researchers and 334 individuals or partners with lived experience of adenomyosis from 48 high-, middle- and low-income countries. There were 291 participants in the second round. PARTICIPANTS/MATERIALS, SETTING, METHODS: Stakeholders included active researchers in the field, healthcare professionals involved in diagnosis and treatment, and people and their partners with lived experience of adenomyosis. The core component of the process was a 2-step modified Delphi electronic survey. The Steering Committee analysed the results and created the final core outcome set (COS) in a semi-structured meeting. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 241 outcomes was identified and distilled into a 'long list' of 71 potential outcomes. The final COS comprises 24 specific and 26 generic core outcomes across nine domains, including pain, uterine bleeding, reproductive outcomes, haematology, urinary system, life impact, delivery of care, adverse events and reporting items, all with definitions provided by the Steering Committee. Nineteen of these outcomes will apply only to certain study types. Although not included in the COS, the Steering Committee recommended that three health economic outcomes should be recorded. LIMITATIONS, REASONS FOR CAUTION: Patients from continents other than Europe were under-represented in this survey. A lack of translation of the survey might have limited the active participation of people in non-English speaking countries. Only 58% of participants returned to round two, but analysis did not indicate attrition bias. There is a significant lack of scientific evidence regarding which symptoms are caused by adenomyosis and when they are related to other co-existent disorders such as endometriosis. As future research provides more clarity, the appropriate review and revision of the COS will be necessary. WIDER IMPLICATIONS OF THE FINDINGS: Implementing this COS in future studies on the treatment of adenomyosis will improve the quality of reporting and aid evidence synthesis.

Reproductive performance following hysteroscopic treatment of intrauterine adhesions: single surgeon data.

Background: Intrauterine adhesions can negatively affect reproductive outcomes by causing infertility, miscarriage and preterm birth in women. Hysteroscopic surgery is now widely accepted as the treatment of choice in symptomatic women to restore reproductive function. Objectives: To analyse the patient characteristics and long-term reproductive outcomes of women who received treatment for intrauterine adhesions under the care of a single surgeon. Materials and Methods: In this retrospective analysis, all women who underwent hysteroscopic surgery for intrauterine adhesions under the care of the same surgeon between January 2001 and December 2019 were identified and their data were evaluated. Relevant demographic, diagnostic and reproductive outcome data was procured from patient notes. Referring doctors and patients were contacted to obtain missing information. Main outcome measures: Live birth and miscarriage rates. Results: 126 women were treated for intrauterine adhesions. Of those women who were trying to conceive, 71.4% (65/91) achieved pregnancy, 58.2% (53/91) had live births and 13.2% (12/91) had miscarriages. No statistically significant difference was found in the live birth rates when data was analysed in subgroups based on age, reason for referral/aetiology and severity of pathology. Conclusions: Hysteroscopic surgery leads to live birth in the majority of women with intrauterine adhesions. The lack of statistically significant difference in live birth rates across subgroups, including advanced age and severe pathology, suggests that surgery in all women wanting to conceive can be justified. What is new?: Hysteroscopic treatment can lead to successful outcomes even in the presence of severe adhesions and in older women with appropriate treatment.

Impact of the COVID-19 pandemic on surgery for severe endometriosis in the UK: a national database study.

Background: The COVID-19 pandemic has had a significant effect on healthcare services, particularly affecting patients who suffer from chronic conditions. However, the pandemic's effect on endometriosis surgery is not yet known. Objectives: To determine the impact of the COVID-19 pandemic on surgery for severe endometriosis in the UK at a national, regional and centre-level. Materials and Methods: The British Society for Gynaecological Endoscopy (BSGE) collects data nationally on all operations for severe endometriosis which involve dissection of the pararectal space. Annual audits of this database were obtained from the BSGE. Publicly available data on COVID-19 cases and population were obtained from the UK Office for National Statistics. Main outcome measures: Numbers of annual BSGE-registered endometriosis operations. Results: A total of 8204 operations were performed. The number of operations decreased by 49.4% between 2019 and 2020 and then increased in 2021, but remained 10.5% below average pre-pandemic levels, indicating at least 980 missed operations between 2019-2020. Median operations per centre decreased by 51.0% in 2020 (IQR 29.4% - 75.0%) and increased in 2021 but remained 33% below pre-pandemic levels. There was no change in the type of surgery performed. All 11 administrative regions of Great Britain had reduced numbers of operations in 2020 compared with the average for 2017-2019, with a median 44.2% decrease (range 13.3% - 67.5%). Regional reduction in operations was correlated with COVID-19 infection rates (r=0.54, 95% CI of r 0.022 - 1.00, p=0.043). Conclusion: The number of operations performed annually in the UK for severe endometriosis fell dramatically during the COVID-19 pandemic and is yet to normalise. What's new?: This study shows the dramatic effect that the COVID-19 pandemic has had on UK services for endometriosis surgery, which may continue to affect patients and clinicians for a considerable time to come.
