Comparison of Transvaginal Natural Orifice Surgery (vNOTES) and Laparoscopic Tubal Ligation: Effects on Postoperative Pain, Sexual Functions, and Surgical Outcomes

Abstract

Introduction: Vaginal natural orifice transluminal endoscopic surgery (vNOTES) is a novel minimally invasive technique that eliminates the need for abdominal incisions. Compared to conventional laparoscopy (CL), vNOTES may offer reduced postoperative pain and faster recovery. While laparoscopy is the standard method for bilateral tubal ligation (BTL), limited comparative data exist regarding vNOTES for this indication. Aim: To compare postoperative outcomes, pain levels, and sexual function following BTL performed via vNOTES versus CL. Material and Methods: This retrospective comparative study included 43 women who underwent elective BTL between September 2023 and December 2024 (vNOTES: n = 23; CL: n = 20). Pain was assessed using a visual analog scale (VAS) at 1, 6, and 24 hours postoperatively. Shoulder pain incidence, intra-abdominal pressure, need for intraoperative opioids, and 6-item Female Sexual Function Index (FSFI-6) scores were also evaluated. Operative time, blood loss, and length of hospital stay were recorded. Results: All procedures were completed without major complications. VAS pain scores at all measured time points were significantly lower in the vNOTES group (P < .05). Shoulder pain occurred in 15% of vNOTES cases versus 85% in the CL group (P < .001). Intra-abdominal pressure and intraoperative opioid requirements were significantly lower in the vNOTES group (P < .05). No significant differences were observed between groups in sexual function scores, operative time, blood loss, or hospital stay (P > .05). Conclusions: vNOTES is a safe and effective alternative to CL for female sterilization. It offers significant benefits in terms of reduced early postoperative and shoulder pain, without negatively affecting sexual function or surgical safety. These findings highlight the potential advantages of vNOTES as a minimally invasive technique in gynecologic surgery.
