Background: Uterine fibroids are the most frequently diagnosed gynaecological tumours, and they often require surgical treatment (conventional laparoscopic myomectomy—CLM). The introduction and evolution of robotic-assisted laparoscopic myomectomy (RALM) in the early 2000s has expanded the range of minimally invasive options for the majority of cases. This study aims to compare RALM with CLM and abdominal myomectomy (AM). Methods and materials: Fifty-three eligible studies adhered to the pre-established inclusion criteria and were subsequently evaluated for risk of bias and statistical heterogeneity. Results: The available comparative studies were compared using surgical outcomes, namely blood loss, complication rate, transfusion rate, operation duration, conversion to laparotomy, and length of hospitalisation. RALM was significantly superior to AM in all assessed parameters other than operation duration. RALM and CLM performed similarly in most parameters; however, RALM was associated with reduced intra-operative bleeding in patients with small fibroids and had lower rates of conversion to laparotomy, proving RALM as a safer overall approach. Conclusion: The robotic approach for surgical treatment of uterine fibroids is a safe, effective, and viable approach, which is constantly being improved and may soon acquire widespread adoption and prove to be superior to CLM in certain patient subgroups.

Background/Objectives: Obesity is a well-established risk factor for endometrial cancer and presents challenges for surgical management. Robotic-assisted surgery offers a minimally invasive approach with potential benefits for obese patients. This study sought to assess the impact of body mass index (BMI) on surgical performance and short-term outcomes in patients undergoing robotic surgery for early-stage endometrial cancer, focusing on follow-up and perioperative treatment. Methods: A retrospective analysis was conducted on 54 patients with early-stage endometrial cancer who underwent a robotic total hysterectomy, bilateral salpingo-oophorectomy, and indocyanine green sentinel lymph node biopsy between January 2021 and December 2024 at two tertiary centers. Patients were stratified by body mass index. Surgical variables, sentinel lymph node detection rates, peri- and postoperative complications, length of hospital stay, and short-term oncologic outcomes were assessed. Statistical comparisons were performed using ANOVA, chi-square tests, and Pearson’s correlation analysis. Results: The mean patient age was 59.7 years, with a mean BMI of 31.1 kg/m2. Bilateral sentinel lymph node detection was successful in 87% of cases, with no significant differences between BMI groups. Console time, hospital stay, and complication rates were comparable across BMI categories. Console time positively correlated with the number of lymph nodes removed (r = 0.302, p = 0.026), but not with BMI. At a mean follow-up of 24.4 months, no recurrences were observed. Conclusions: Robotic surgery for early-stage endometrial cancer is safe and effective regardless of BMI, including in patients with Class III obesity. BMI does not negatively impact surgical or short-term oncologic outcomes, supporting robotic surgery as an optimal approach in obese endometrial cancer patients.

Background/Objectives: Tubal dysfunction may be a contributing factor in up to 35% of infertility cases, rendering tubal patency assessment a vital component of the infertility workup. In this review we examined the diagnostic efficacy and tolerability of hysterosalpingo-foam sonography (HyFoSy) and compared it to hysterosalpingography (HSG) and hysterosalpingo-contrast sonography (HyCoSy). Methods: Online databases were systematically searched and evaluated according to the PRISMA 2020 guidelines. Statistical heterogeneity was assessed. Diagnostic sensitivity, specificity and inter-method agreement were evaluated, along with mean pain scores. Results: This analysis included data from 9 studies and 1354 patients with conclusive diagnostic data from 2422 tubes and 1294 patients with data on intra-procedural pain. With regard to HyFoSy and HyCoSy comparison, pooled sensitivity was 87% and 69%, respectively (p = 0.074), while pooled specificity was 95% and 85%, respectively, favoring HyFoSy (p < 0.001). HyFoSy was more tolerable with regard to pain, but this was not statistically significant. Regarding the HyFoSy and HSG comparison, pooled Cohen’s k was 0.38, indicating fair-moderate agreement. In subsequent analysis, with HSG as a reference standard, HyFoSy demonstrated low sensitivity (61%) but high specificity (87%). With regard to experienced pain, HyFoSy and HSG had a difference of 2.4 units on a 10-point scale, favoring HyFoSy (p < 0.001). Conclusions: HyFoSy was superior to HyCoSy and may be used as a first-line tubal assessment method, with HSG being utilized in inconclusive cases. However, further research is still required due to the small number of available studies.

We present the case of a 54‐year‐old woman diagnosed with uterine leiomyosarcoma that produced beta‐human chorionic gonadotropin (β‐hCG), evident by both serum and immunohistologic examination. Based on this and similar cases from the available literature, β‐hCG‐producing sarcomas tend to have poorer prognosis, indicating that β‐hCG could potentially be used as a marker of disease status and response to the therapy; however, this association is inconsistent and should be further investigated.

IntroductionCornual pregnancy is rare, accounting for approximately 2-4% of all ectopic pregnancies [1]. By definition, it refers to the implantation and development of a gestational sac at the proximal and lateral regions of the uterus (aka uterine horns or cornua). As with the majority of other types of ectopic pregnancy, cornual pregnancy diagnosis is based on clinical suspicion, β-hCG measurements and transvaginal ultrasound findings [2]. As with other types of ectopic pregnancy, cornual pregnancy is associated with severe patient morbidity and mortality [3]. Therefore, timely and accurate diagnosis is key as it directly affects treatment type and urgency. Several management options are available from the conservative (methotrexate administration and expectant management) up to the more radical side of the spectrum (cornuotomy, cornual resection, hysterectomy) [4]. Hysteroscopy is an additional option that combines effective and complete removal of the gestational sac, without severely affecting uterine anatomy, however its application usually requires imaging guidance [5].In this report, we present the case of a cornual ectopic pregnancy, which could not be diagnosed via traditional ultrasonographic imaging and instead was verified by MRI imaging. Subsequently, guided by the MRI imaging data, hysteroscopic resection and removal of all products of gestation was safely and successfully performed without any complications and with the patient making a swift recovery.

Key Clinical Message: Hysteroscopic resection of ectopic cornual pregnancy following MRI imaging is a safe and effective treatment option without significantly impacting fertility potential or increasing the risk of future obstetrical complications.
