Vaginal Natural Orifice Transluminal Endoscopic Surgery Versus Laparoscopic Tubal Ligation for Interval Sterilization: A Retrospective Cohort Study

Background To compare the transvaginal natural orifice transluminal endoscopic surgery (vNOTES) approach versus conventional laparoscopy in bilateral tubal ligation for interval sterilization regarding perioperative outcomes, postoperative pain, and sexual function. Methods This retrospective cohort study at a tertiary center included 88 women who underwent elective tubal ligation between February 2024 and October 2025 (vNOTES: n = 39; laparoscopy: n = 49). Women aged 18–45 years seeking permanent contraception with American Society of Anesthesiologists (ASA) physical status classification ≤ 3 were included. Primary outcomes included operative time and estimated blood loss (assessed by hemoglobin/hematocrit changes). Secondary outcomes included length of hospital stay, postoperative pain assessed using a visual analog scale (VAS) at 6 and 24 h postoperatively, total amount of analgesic requirements and sexual function evaluated using the Female Sexual Function Index (FSFI) preoperatively and at 1 and 6 months postoperatively. Statistical analysis used t ‐test/Mann–Whitney U test and chi‐square/Fisher's exact test ( α = 0.05). Results Baseline characteristics were comparable between groups (vNOTES: n = 39; laparoscopy: n = 49). No significant differences were found in hemoglobin changes or operative time. vNOTES demonstrated significantly shorter hospital stay (14.90 ± 7.27 vs. 20.10 ± 3.96 h, p < 0.001), lower postoperative total amount of analgesic requirements (1.72 ± 0.76 vs. 4.88 ± 1.63 doses, p < 0.001), and reduced VAS pain scores at 6 and 24 h. No intraoperative conversions occurred. Complication rates were similar between groups ( p > 0.999). FSFI scores showed no significant differences at baseline, 1, or 6 months postoperatively. Conclusion vNOTES for tubal ligation offers significant advantages in postoperative pain reduction, decreased analgesic requirements, and shorter hospital stay while maintaining comparable operative times, safety, and sexual function outcomes.
