Background: A uterine niche after caesarean section may play a role in secondary infertility. The transvaginal approach is a newly developed minimally invasive surgical technique for repairing a uterine isthmocele.

Objectives: To report on the feasibility, effectiveness, and safety of the transvaginal uterine niche repair. The technique is demonstrated in a live-surgery video.

Materials and methods: A retrospective chart review involving all patients with secondary infertility who underwent a transvaginal uterine niche repair in Ziekenhuis Oost-Limburg between August 2019 and July 2022 was conducted.

Main outcome measures: We compared the pre- and postoperative residual myometrial thickness as a primary surgical outcome measurement. The pregnancy ratio and the peri- and postoperative complications were also reported.

Results: A total of 26 patients underwent a transvaginal uterine niche repair with an average operation time of 44 minutes. No major surgical complications were reported. 23 patients (88%) had good postoperative myometrial integrity, while 3 patients had a partial or complete postoperative recurrence of the uterine niche. The average pre- and postoperative myometrial thicknesses were 1.6 mm and 6.4 mm respectively. 64% of patients desiring pregnancy became pregnant after the transvaginal niche repair. There were no obstetric complications reported.

Conclusions: A transvaginal approach is a safe and effective technique for uterine niche repair. It offers good results in re-establishing myometrial integrity and may favour fertility outcomes. It represents a valid minimal invasive procedure for patients with a very thin residual myometrial thickness and secondary infertility without leaving a visual scar.

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.

Background: Inguinofemoral lymphoceles are a common postoperative complication after inguinofemoral lymphadenectomy (LNE) and a challenge for patients as well as physicians. We report here our preliminary experience in the surgical management of a recurrent lymphocele using indocyanine green (ICG) detection, followed by robotic-assisted closure of the lymphatic leaks.

Objectives: The aim of this article is to illustrate the surgical steps of ICG-assisted detection of inguinal lymphatic leaks and their surgical treatment by means of robot-assisted suturing. Furthermore, the feasibility of the approach will be evaluated.

Materials and methods: A 59-year-old woman with locally advanced squamous cell carcinoma of the vulva and previous conventional bilateral inguinofemoral LNE presented with symptomatic therapy-resistant lymphoceles in the groin. After a lengthy and frustrating course of standard therapy, she was offered the off-label option surgical treatment with ICG detection and subsequent robot-assisted ligation of the leaks, using the Da Vinci robotic system™.

Main outcome measures: Perioperative data, specific aspects of the surgical approach specifics, objective and subjective outcomes of the new approach.

Results: The procedure was performed as planned, with no intraoperative complications or device-related issues. The postoperative course was uneventful, and the patient developed no further lymphoceles.

Conclusion: Visualisation of the leakage by ICG combined with minimally invasive robotic-assisted laparoscopy is a promising therapy option. The pictures and videos demonstrate our experience in regard of the safety, feasibility, and usefulness of this procedure. Further studies will be needed, to prove the absolute efficacy of the technique and express a general recommendation in regard of this approach for the treatment of inguinofemoral lymphoceles.

The translation of impedance (R), current (I), and voltage (V) into tissue effects and the understanding of the settings of electrosurgical units is not obvious if judged by the many questions during live surgery. Below 200 V, the current heats the tissue until the steam of boiling stops the current. Thus, slower heating, because of less energy or a larger contact area, results in deeper coagulation. Above 200 V and a duty cycle (per cent of time electricity is delivered) of >50% (yellow pedal), sparks become electric arcs, and the heat causes the explosion of superficial cells, i.e. cutting. With higher voltages, cutting is associated with coagulation, i.e. blended current. With even higher voltages and a duty cycle <10% preventing arching, only coagulation occurs (blue pedal; forced coagulation). Voltage being crucially important for tissue effects, newer electrosurgical units deliver a constant voltage and limit the energy output (Maximal Watts: W=I*V= joules/sec). Unfortunately, the electrosurgical units indicate the combination of voltage and duty cycles as a force of cutting (pure cutting or blended) or coagulation (soft, forced or spray) current. It is important that the surgeon understands whether electrosurgical units control voltages or output, as well as the electrical basics of the different settings and programs used.

Background: Endometrial Ablation (EA) is an alternative to hysterectomy for the management of abnormal uterine bleeding (AUB); however, it does not eliminate the need for future surgical re-intervention.

Objectives: The primary objective of this study was to establish long-term clinical outcomes including the risk of hysterectomy in women who had undergone a primary EA.

Materials and methods: This is a retrospective population-based cohort study utilising administrative data from the Canadian province of Ontario. This study assesses patients undergoing surgery in a publicly funded health care system.

Main outcome measures: We assessed women in Ontario undergoing a primary EA over a 15-year period. The primary outcome was hysterectomy within 5 years of primary EA. Secondary outcomes included myomectomy and repeat EA. All outcomes were also reported for 1, 3, 5, 10 and 15 years of follow-up. Logistic regression was used to establish predictors of hysterectomy within 5 years of primary EA.

Results: A total of 76,446 primary EAs were evaluated from 2002-2017, with 16,480 (21.56%) undergoing a subsequent surgical intervention. The average age of primary EA was 43.8 (+/- 6.3) years. Within 5 years, the evaluable cohort was 52,464, with 8,635 (16.46%) of women having proceeded to hysterectomy, 664 (1.27%) to myomectomy, and 2,468 (2.8%) to repeat ablation. By 15-years follow-up, the evaluable cohort was 1,788, with 28.75% had undergone a hysterectomy, 2.01% a myomectomy, and 5.20% a repeat EA. On logistic regression analysis, advancing age at time of EA was associated with significantly decreased odds of hysterectomy (OR=0.94, 95% CI 0.935-0.944, p<.0001) as was increasing surgical experience (OR=0.997, 95% CI 0.994-1.000, p=.022). Conversely, complex diagnosis (OR=1.102, 95% CI 1.042-1.164, p<.0001) and previous abdominal surgery (OR=1.288, 95% CI 1.222-1.357, p<0.0001) were associated with increased risk of subsequent hysterectomy.

Conclusion: Primary EA is associated with a high risk of progression to subsequent hysterectomy or other surgical intervention, without evidence of plateau of risk with long term follow-up.

What is new?: This study has the longest follow-up assessing hysterectomy outcomes in women undergoing a primary EA, with 28.75% of women having undergone a hysterectomy within 15 years of their EA.

Background: Adenomyosis is a chronic, debilitating condition characterised by the presence of endometrial- like glands and stroma within the myometrium. While hysterectomy remains the definitive treatment, uterus- sparing surgeries may be a possible option for patients desiring to maintain fertility. Surgical management, along with medical treatment and/or Assisted Reproductive Technology (ART), can improve outcomes.

Objectives: To provide a step-by-step video demonstration of robotic-assisted excision of diffuse adenomyosis affecting the posterior uterine wall.

Materials and methods: This video article describes the use of a robotic platform in conjunction with intracavitary indocyanine green (ICG) for the uterus-sparing excision of diffuse adenomyosis.

Main outcome measures: Perioperative data, specifics of the surgical approach, and both objective and subjective outcomes of this surgical approach.

Results: A 38-year-old nulligravid patient with a history of chronic pelvic pain and infertility underwent surgical management of adenomyosis following two unsuccessful IVF cycles. The excisional surgery resulted in minimal blood loss (60 ml) and the patient was discharged on the same day of surgery with no complications.

Conclusion: In select patients, robotic-assisted surgical management of diffuse adenomyosis can be advantageous. Leveraging the benefits of robotic technology, combined with appropriate surgical techniques, facilitates the performance of extensive surgeries with minimal morbidity and favourable outcomes.

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.

The management of symptomatic uterine fibroids during pregnancy is a challenging situation. In some cases, surgical therapy can be required. Reports indicate that both laparotomy and laparoscopy are safe methods. However, laparoscopy is associated with less morbidity. This paper describes the case of a 31-year-old woman with a symptomatic uterine fibroid which was removed by gasless laparoscopy.
