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).

n = 88 women
1.72
Results
1.72
± 0.76 vs. 4.88 ± 1.63 doses
women needed fewer painkiller doses after vaginal-approach surgery than after laparoscopy
n = 88 women
More results

Baseline characteristics were comparable between groups (vNOTES: n = 39; laparoscopy: n = 49).

No intraoperative conversions occurred.

Complication rates were similar between groups (p > 0.999).

Female Sexual Function Index 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.
