Objective: To compare hysterectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) versus total laparoscopic hysterectomy (TLH) as a day-care procedure.Design: Parallel group, 1:1 randomised single-centre single-blinded trial, designed as a non-inferiority study with a margin of 15%.Setting: Belgian teaching hospital.Population: Women aged 18-70 years scheduled to undergo hysterectomy for benign indications.Methods: Randomisation to TLH (control group) or vNOTES (experimental group). Stratification according to uterine volume. Blinding of participants and outcome assessors.Main Outcome Measures: The primary outcome was hysterectomy by the allocated technique. We measured the proportion of women leaving within 12 hours after hysterectomy and the length of hospital stay as secondary outcomes.Results: We randomly assigned 70 women to vNOTES (n = 35) or TLH (n = 35). The primary endpoint was always reached in both groups: there were no conversions. We performed a sensitivity analysis for the primary outcome, assuming one conversion in the vNOTES group and no conversions in the TLH group: the one-sided 95% upper limit for the differences in proportions of conversion was estimated as 7.5%, which is below the predefined non-inferiority margin. More women left the hospital within 12 hours after surgery after vNOTES: 77 versus 43%, difference 34% (95% CI 13-56%), P = 0.007. The hospital stay was shorter after vNOTES: 0.8 versus 1.3 days, mean difference -0.5 days, (95% CI -0.98 to -0.02), P = 0.004.Conclusions: vNOTES is non-inferior to TLH for successfully performing hysterectomy without conversion. Compared with TLH, vNOTES may allow more women to be treated in a day-care setting.Tweetable Abstract: RCT: vNOTES is just as good as laparoscopy for successful hysterectomy without conversion but allows more day-care surgery.
