Background: Vesico-vaginal fistula (VVF) is a rare but debilitating condition, characterised by an abnormal connection between the bladder and vagina. While obstetric-related cases prevail in developing countries, iatrogenic fistulas are more common in industrialised ones, often resulting from pelvic surgeries.

Objectives: The optimal timing for surgical correction of VVF remains debated, often leaning towards delayed intervention. Here we report a successful early laparoscopic repair of an iatrogenic VVF following hysterectomy.

Materials and methods: The patient, a 54-year-old woman, presented with VVF after a hysterectomy. The laparoscopic repair was performed promptly upon diagnosis.

Main outcome measures: To assess the feasibility and effectiveness of an early repair of a gynaecological-related VVF.

Results: First, cystoscopy identified the bladder edge of the VVF. Second, laparoscopy was performed and the vesico-vaginal dissection was carried out. The excision of the previous stitches and of the fibrotic tissue was undertaken to create free flaps for suturing. The bladder was repaired in a double layer, and a single layer was applied to the vagina. Finally, the omentoplasty was done. The patient was discharged on postoperative day 5. No complications occurred.

Conclusions: This successful case demonstrates the feasibility and safety of early laparoscopic repair for gynaecological surgery-related vesico-vaginal fistulae. While acknowledging the need for further studies to standardise techniques, this report contributes to the evolving understanding of optimal management for this complex condition.

Background: Abdominal hysterectomy has been largely replaced by minimally invasive surgery. Nevertheless, in some situations, a minimally invasive intervention must be converted to laparotomy. Factors associated with conversion to laparotomy are still a matter of debate.

Objective: The aim of this study was to evaluate the clinicopathological factors associated with the conversion of laparoscopic hysterectomy to laparotomy.

Materials and methods: The risk factors for conversion of a preplanned laparoscopic procedure to laparotomy were retrospectively evaluated in 441 patients undergoing a hysterectomy for a benign indication between 2016 and 2020. Associations between the clinical factors were analysed using Pearson's chi-square and Fisher's exact test, and predictive values for conversion were assessed through multivariate logistic regression.

Result: Conversion occurred in 32 (7.3%) of the cases. Significant differences were detected for uterus weight (576.9gr vs 174.6gr, p<0.001), myoma size (7.0 cm vs. 1.8 cm, p<0.001), and presence of triple diagnosis consisting of leiomyoma, adenomyosis uteri, and pathological adnexal findings (p<0.013). The conversion resulted in prolonged surgery time (181.6 min vs. 119.6 min, p<0.001) and hospital stay (4.0 vs. 3.1 days, p<0.001), as well as an increased rate of wound infection (15.6% vs. 3.4%, p<0.001). A 10g increase in uterus weight raised the risk of conversion by 7.0%, and a 1cm increase in myoma diameter by 7.3%, while adnexal pathologies and extensive adhesions increased the odds of conversion to laparotomy threefold (ORs of 3.2, 1.09-9.6 and 3.6, 1.3-10.0, respectively).

Conclusion: Uterus weight, myoma size, the coexistence of pathological adnexal findings, and non-physiological adhesions are independent risk factors for conversion.

What is new?: This study provides data regarding the risk and factors increasing this risk for conversion to laparotomy during laparoscopic hysterectomy.

Background: More than two decades ago, the advent of robotic laparoscopic surgery marked a significant milestone, featuring the introduction of the AESOP robotic endoscope control system and the ZEUS robotic surgery system. The latter, equipped with distinct arms for the laparoscope and surgical instruments, was designed to accommodate remote connections, enabling the practice of remote telesurgery as early as 2001. Subsequent technological progress has given rise to a range of options in today's market, encompassing multi-port and single-port systems, both rigid and flexible, across various price points, with further growth anticipated.

Objective: This article serves as an indispensable guide for gynaecological surgeons with an interest in embracing robotic surgery.

Materials and methods: Drawing insights from the experience of the Strasbourg training centre for minimally invasive surgery (IRCAD), this article offers a comprehensive overview of existing robotic platforms in the market, as well as those in development.

Results: Robotic surgical systems not only streamline established operative methods but also broaden the scope of procedures, including intra- and transluminal surgeries. As integral components of the digital surgery ecosystem, these robotic systems actively contribute to the increasing integration and adoption of advanced technologies, such as artificial intelligence-based data analysis and support systems.

Conclusion: Robotic surgery is increasingly being adopted in clinical practice. With the growing number of systems available on the marketplace, the primary challenge lies in identifying the optimal platform for each specific procedure and patient. The seamless integration of robotic systems with artificial intelligence, image-guided surgery, and telesurgery presents undeniable advantages, enhancing the precision and effectiveness of surgical interventions.

What is new?: This article provides a guide to the robotic platforms available on the market and those in development for gynaecologists interested in robotic surgery.

The International Society of Ultrasound in Obstetrics and Gynecology (ISUOG) and International Deep Endometriosis Analysis (IDEA) group, the European Endometriosis League (EEL), the European Society for Gynaecological Endoscopy (ESGE), the European Society of Human Reproduction and Embryology (ESHRE), the International Society for Gynecologic Endoscopy (ISGE), the American Association of Gynecologic Laparoscopists (AAGL) and the European Society of Urogenital Radiology (ESUR) elected an international, multidisciplinary panel of gynecological surgeons, sonographers and radiologists, including a steering committee, which searched the literature for relevant articles in order to review the literature and provide evidence-based and clinically relevant statements on the use of imaging techniques for non-invasive diagnosis and classification of pelvic deep endometriosis. Preliminary statements were drafted based on a review of the relevant literature. Following two rounds of revisions and voting orchestrated by chairs of the participating societies, consensus statements were finalized. A final version of the document was then resubmitted to the society chairs for approval. Twenty statements were drafted, of which 14 reached strong and three moderate agreement after the first voting round. The remaining three statements were discussed by all members of the steering committee and society chairs and rephrased, followed by an additional round of voting. At the conclusion of the process, 14 statements had strong and five statements moderate agreement, with one statement left in equipoise. This consensus work aims to guide clinicians involved in treating women with suspected endometriosis during patient assessment, counselling and planning of surgical treatment strategies.

Background: Obstructive defecation syndrome (ODS) is frequently associated with pelvic organ prolapse (POP) and compromises the quality of life in affected patients. In cases conservative treatment fails surgical therapy is required.

Objectives: The video case study combines a laparoscopic resection rectopexy (RRP) with a mesh sacrocolpopexy (SCP) in an interdisciplinary surgical approach.

Materials and methods: In this video an 86-year-old woman with ODS and POP, suffering from a dolichocolon with rectal intussusception, an apical prolapse after total hysterectomy 1990, and occasional stress urinary incontinence underwent interdisciplinary laparoscopic surgery. A tubular anterior rectal and sigmoid resection with suture rectopexy as in a resection rectopexy (RRP) was combined with a sacrocolpopexy (SCP) using a synthetic mesh.

Main outcome measures: Surgical outcome including postoperative morbidity, functional bowel evacuation, and POP reconstitution as in POP-Q score after surgery were documented.

Results: No intra- or postoperative complications occurred. At 6 months follow-up clinical outcomes for ODS, bowel dysfunction, and faecal control were improved. Anatomical outcome for POP and stress urinary incontinence symptoms were corrected.

Conclusions: We report a promising interdisciplinary surgical approach as a single treatment option for the complex medical condition of women suffering from ODS and POP combining laparoscopic RRP with SCP. This surgical approach proved to be feasible, safe, and effective.

Background: The inferior hypogastric plexus (IHP) is a crucial structure for female continence and sexual function. A nerve-sparing approach should be pursued to reduce the risk of pelvic plexus damage during retroperitoneal pelvic surgery.

Objectives: To analyse the relationship between the female IHP and several pelvic anatomical landmarks.

Materials and methods: Standardised cadaveric dissection was performed on 5 nulliparous female cadavers. The relationships of the IHP and the mid-cervical plane (MCP), the mid-sagittal plane (MSP), and the uterosacral ligament (USL) were investigated.

Main outcome measures: Distance between IHP and MCP, MSP, and USL.

Results: Distances between the right IHP and the right MSP (mean distance: 16.3 mm; range: 10.0-22.5 mm) and the right USL (mean distance: 4.8 mm; range: 0-15.0 mm) were shorter than those between the left IHP and ipsilateral landmarks (left MSP distance: 23.5 mm; range 18.0-30.0 mm; left USL distance: 5.0 mm; range: 0-20.0 mm). Although the MCP was 3.3 mm (range: 2.5-4.0 mm) left and lateral to the midsagittal line, the right IHP was closer to the MCP (mean distance: 19.6 mm; range: 13.0-25.0 mm) than the left one (mean distance: 20.2 mm; range: 15.0-26.0 mm).

Conclusions: Distances between the right IHP and the MSP, MCP, and ipsilateral USL, are shorter compared to these associated to the left IHP.

What is new?: Right autonomic pelvic plexus is closer to the midline planes and the ipsilateral USL. These anatomical relationships may be greatly helpful for pelvic surgeon while facing retroperitoneal pelvic surgery and looking for a nerve-sparing approach.

Background: The NuvaRing®, a hormonal vaginal contraceptive device, has gained widespread usage due to its favourable efficacy and safety profiles. Exceedingly rare instances of unintended misplacement in the bladder have been reported. This study presents a review of the literature and the first video report illustrating the extraction of an intravesical NuvaRing®, discussing diagnostic and therapeutic approaches.

Objective: To illustrate an effective method for intravesical NuvaRing® retrieval and raise awareness about this unusual complication.

Materials and methods: A 27-year-old patient with low urinary tract symptoms related to NuvaRing® misplacement underwent diagnostic procedures, including ultrasound and diagnostic cystoscopy. A cystoscopic extraction under general anaesthesia was performed.

Main outcome measures: The effectiveness of pelvic ultrasound for diagnosing an intravesical foreign body, successful cystoscopic removal of NuvaRing® from the bladder, and symptom resolution were assessed.

Results: The intravesical NuvaRing® was identified through pelvic ultrasound. During cystoscopy, the ring was detected inside the bladder. Multiple attempts with cystoscopic alligator graspers were made; the NuvaRing® was eventually extracted using transurethral Heiss forceps. The patient experienced minimal blood loss and was discharged the following day, reporting relief from symptoms.

Conclusions: Unintentional NuvaRing® placement in the bladder is an extremely rare event that healthcare providers should consider when patients present with urinary symptoms and pelvic pain. Pelvic ultrasound is an efficient diagnostic tool, possibly averting the need for further imaging techniques. Cystoscopy remains the preferred method for diagnosis and treatment. This video report illustrates an effective technique for NuvaRing ® extraction, especially when appropriate graspers are unavailable. Adequate instruction on NuvaRing® insertion should always be emphasised.

Background: Laparoscopic myomectomy is increasingly considered the gold standard uterine preserving procedure and has well documented benefits over the open approach. Barriers that women have in accessing the most appropriate treatment need to be addressed to ensure optimal patient care and outcomes.

Objectives: To analyse rates of open and laparoscopic myomectomy at a large NHS trust and identify how many cases could potentially have been performed laparoscopically, and any variation between sites.

Materials and methods: A retrospective review of preoperative imaging reports and a surgical database containing information for all myomectomies performed between 1st January 2015 and 31st December 2022.

Main outcome measures: Number of procedures suitable for alternative surgical approach; length of hospital stay; estimated blood loss; cost differences.

Results: 846 myomectomies were performed; 656 by laparotomy and 190 by laparoscopy. 194/591 (32.8%) open myomectomies could have been performed laparoscopically and 26/172 (15.1%) laparoscopic myomectomies may have been better performed via an open approach. Length of hospital stay, and estimated blood loss were significantly higher in the open group. Had cases been performed as indicated by pre-operative imaging, the cost differences ranged from -£115,752 to £251,832.

Conclusions: There is disparity in access to the gold standard care of laparoscopic myomectomy. Due to multifactorial reasons, even at sites where the rate of laparoscopic myomectomy is high, there is still underutilisation of this approach. It is clear that there is scope for change and "levelling up" of this imbalance.

What is new?: Robust pathways and guidelines must be developed, and more laparoscopic surgeons should be trained to optimise care for women with fibroids.

Background: Reproductive surgery has long been neglected and is perceived to be simple surgery that can be undertaken by all gynaecologists. However, given the ever-expanding knowledge in the field, reproductive surgery now comprises surgical interventions on female reproductive organs that need to be carefully planned and executed with consideration given to the individuals symptoms, function of the organ and fertility concerns.

Objectives: To discuss the different perspectives of reproductive surgeons and other gynaecological surgeons, e.g., gynaecological oncologists, and advanced minimally invasive surgeons, regarding diagnosis and management of pelvic pathology that affects reproductive potential. Furthermore, to highlight the gaps in knowledge and numerous controversies surrounding reproductive surgery, while summarising the current opinion on management.

Materials and methods: Narrative review based on literature and the cumulative experience of the authors.

Main outcome measures: The paper does not address specific research questions.

Conclusions: Reproductive surgery encompasses all reproductive organs with the aim of alleviating symptoms whilst restoring and preserving function with careful consideration given to alternatives such as expectant management, medical treatments, and assisted reproductive techniques. It necessitates utmost technical expertise and sufficient knowledge of the female genital anatomy and physiology, together with a thorough understanding of and respect to of ovarian reserve, tubal function, and integrity of the uterine anatomy, as well as an up-to-date knowledge of alternatives, mainly assisted reproductive technology.

What is new?: A holistic approach to infertile women is only possible by focusing on the field of reproductive medicine and surgery, which is unattainable while practicing in multiple fields.

Background: Isthmoceles are a growing clinical concern.

Objectives: To evaluate the accuracy of diagnosis of isthmoceles by imaging and to correlate the dimensions with clinical symptoms and histopathology.

Materials and methods: Prospective study of women (n=60) with ≥1 C-section undergoing hysterectomy. Isthmoceles were measured by imaging before surgery and macroscopically on the specimen after hysterectomy, followed by histological analysis.

Main outcome measures: Accuracy of isthmocele diagnosis, correlation with clinical symptoms, and histopathological findings.

Result: By imaging, isthmoceles were slightly deeper (P=0.0176) and shorter (P=0.0045) than macroscopic measurements. Differences were typically small (≤3mm). Defined as an indentation of ≥2 mm at site of C-section scar, imaging diagnosed 2 isthmoceles consequently not seen by histology and missed 3. Number of prior C-sections increased isthmocele severity but neither the incidence nor the remaining myometrial thickness (RMT) did. Severity correlated positively with symptoms and histology. However, clinical use was limited. Histological analysis revealed presence of thick wall vessels in 100%, elastosis in 40%, and adenomyosis in 38%. Isthmocele lining was asynchronous with the menstrual phase in 31%.

Conclusions: Dimensions of isthmoceles by imaging were largely accurate with occasionally large differences observed. Number of C-sections did not increase isthmocele incidence, only severity. Indication for surgery remains clinical, considering dimensions and symptoms.

What is new?: Dimensions of isthmoceles should be confirmed before surgery since uterine contractions might change those dimensions. Symptoms increase with dimensions of isthmoceles but are not specific. Endometrial lining within the isthmocele can be asynchronous with the menstrual phase.
