Impact of transvaginal natural orifice transluminal endoscopic surgery on hysterectomy practice

To evaluate the impacts of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) on the hysterectomy route and concomitant adnexal surgery at the time of vaginal hysterectomy (VH).

This retrospective study analyzed all hysterectomies performed for benign indications between 1 January 2017 and 31 December 2019. The period preceding the first case of VH and vNOTES BSO was considered as Pre-vNOTES. The period starting from the date of the first case was considered as Post-vNOTES. The rates per route of hysterectomy and the rate of concomitant adnexal surgery at the time of VH were compared between the two periods.

In hysterectomies performed by surgeons who implemented vNOTES, the proportion of the vaginal route increased from 40.1% to 94.3% (P-value < 0.001); the abdominal route decreased from 37.4% to 3.2% (P-value < 0.001); and the laparoscopic route decreased from 22.5% to 2.5% (P-value < 0.001). The rates of concomitant adnexal procedures performed at the time of VH also showed significant changes. While 39.7% of patients did not undergo any concomitant adnexal surgery during the Pre-vNOTES period, this rate dropped to 8.1% after the implementation of vNOTES (P-value < 0.001). Similarly, the rate of bilateral salpingectomy dropped from 49.3% to 14.2% (P-value < 0.001), whereas the rate of BSO increased from 6.8% to 75% (P-value < 0.001).

Implementation of vNOTES has led to a significant increase in the rate of VH and the rate of concomitant BSO at the time of VH.
