Study ObjectiveTo compare the transvaginal natural orifice transluminal endoscopic surgery (vNOTES) approach with conventional laparoscopy (CL) in opportunistic bilateral salpingectomy (BS) alone for permanent female sterilization as an opportunistic cancer prevention strategy.DesignProspective cohort study.SettingTwo-centered tertiary hospitals.PatientsNinety-six women with a nonprolapsed uterus seeking definitive surgical permanent contraception.InterventionsPatients were scheduled for BS and assigned to a study arm in a 2:1 fashion (CL:vNOTES allocation ratio) concerning patient's choice.Measurements and Main ResultsPatients were followed at their postoperative first week and first month. The visual analog score (VAS), Patient Global Impression of Improvement, and Female Sexual Function Index scales were used to assess the pain, patient satisfaction, and discomfort/pain after vaginal penetration, respectively. Patients who underwent to vNOTES had a significantly higher number of previous abdominal surgery (median difference, 1.97; 95% confidence interval [CI], 1.12–3.48; p = .016). Compared with CL, vNOTES was associated with lower 6-hour (rate ratio [RR], 0.63; 95% CI, 0.50–0.77) and 24-hour (RR, 0.33; 95% CI, 0.23–0.46) postoperative VAS scores and less amount of postoperative analgesics (RR, 0.54; 95% CI, 0.36–0.78). The slope of change in postoperative VAS scores was in a shorter time in the vNOTES group (RR, 0.47; 95% CI, 0.36–0.60). The rate of postoperative improvement was higher in the vNOTES group than the CL group at the postoperative first week (87.5% vs 68.2%, χ2 = 4.232, p = .032) and first month (96.9% vs 87.9%, χ2 = 2.091, p = .140). The rate of patients reporting postoperative decline in Female Sexual Function Index /pain scores (RR, 0.97; 95% CI, 0.47–1.96) was found to be similar in both of the study groups, and no postoperative complication was observed in either group.ConclusionWomen seeking permanent sterilization and who underwent BS for ovarian cancer risk reduction purposes had higher satisfaction, less postoperative pain, lower analgesic requirement, and similar surgical outcomes in the vNOTES group than the CL group, even in patients with previous surgeries and a nonprolapsed uterus. vNOTES approach could be the preferred method for the opportunistic BS in female sterilization.
