Impact of transvaginal natural orifice transluminal endoscopic surgery on hysterectomy practice.

ABSTRACT

STUDY OBJECTIVE: 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). MATERIAL AND METHODS: 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. RESULTS: 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). CONCLUSION: 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.
