Objective: To review of our hospital's experiences in transvaginal natural orifice transluminal endoscopic surgery (vNOTES) and challenges we encountered in performance of the procedure, so as to provide help to medical institutions who are preparing to carry out vNOTES.
Methods: We retrospectively analyzed the data of all patients receiving vNOTES in our hospital from April 2018 to May 2021. Data we collected cover the general characteristics, perioperative outcomes, and complications of the patients.
Results: A total of 1147 patients underwent vNOTES in the past 3 years at our hospital. The total numbers of adnexal surgery, myomectomy, hysterectomy, pelvic floor reconstruction surgery, and malignant tumor surgery performed via vNOTES were 902, 98, 82, 51, and 14, respectively. Eighteen patients were converted to transabdominal laparoscopic surgery. A total of 38 patients had complications according to Clavien-Dindo classification, and the total complication rate was 3.31%. Among these cases of complications, 27 were Grade I, 4 were Grade II, and 7 were Grade III. No complications of Grade IV or V were reported.
Conclusion: The application of vNOTES is safe and feasible for most gynecological surgeries. Moreover, hospitals with traditional laparoscopic equipment are advised to try this technique as there is no need to purchase additional expensive equipment. However, since vNOTES represents a novel approach, the long-term complications and efficacy associated with this technique are pending to be verified through large-scale prospective multicenter randomized controlled studies.

Enhancing repeatability of follicle counting with deep learning reconstruction high-resolution MRI in PCOS patients.
Sci Rep

Department of Radiology, Renmin Hospital of Wuhan University, No. 238 Jiefang Road, Wuchang District, Wuhan, 430060, China.
Follicle count, a pivotal metric in the adjunct diagnosis of polycystic ovary syndrome (PCOS), is often underestimated when assessed via transvaginal ultrasonography compared to MRI. Nevertheless, the repeatability of follicle counting using traditional MR images is still compromised by motion artifacts or inadequate spatial resolution. In this prospective study involving 22 PCOS patients, we employed periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER) and single-shot fast spin-echo (SSFSE) T2-weighted sequences to suppress motion artifacts in high-resolution ovarian MRI.

Article Synopsis
- The study details a modified transvaginal repair technique (V-NOTES) for treating apical vesicovaginal fistulas (VVFs) in 26 patients, with 17 undergoing the V-NOTES procedure between January 2020 and January 2023.
- Outcomes showed an 88.2% success rate, with an average operative time of 104.2 minutes and minimal blood loss (10.45 ml).
- No major complications arose, and even initially failed repairs were successful on subsequent attempts, indicating that V-NOTES is an effective and safe treatment option for apical VVFs.

Introduction: Transvaginal natural orifice specimen extraction surgery (NOSES) is an innovative and feasible approach for left-sided colorectal resections in females. This study aimed to report our experience with transvaginal NOSES for left-sided laparoscopic colorectal resections.
Patients And Methods: We analysed data for all patients with transvaginal extraction performed for left-sided laparoscopic colorectal resections between 2011 and 2021 at a tertiary teaching hospital in Taiwan.

Background: Reduced-port laparoscopic surgery (RPLS) uses the minimum possible number of ports or small-sized ports in laparoscopic surgery. The combination of RPLS and natural orifice specimen extraction (NOSE) minimizes the procedural damage.
Methods: A total of 17 patients diagnosed with right colon cancer were included: 5 patients in the RPLS + NOSE group and 12 patients in the conventional laparoscopic surgery (CL) + mini-laparotomy (ML) group.
