Abstract

ABSTRACT: STUDY OBJECTIVE: To evaluate the safety and feasibility of vaginal natural orifice transluminal endoscopic surgery (vNOTES) for benign gynaecological indications. STUDY DESIGN: Prospective observational study (Canadian Task Force classification II-3) in a non-university teaching hospital. One thousand consecutive patients (2013-2018) who were eligible for vNOTES approach to benign gynaecological surgery were included. RESULTS: Patient data and perioperative outcomes were included for analysis after the vNOTES surgical approach was standardized and made the default route of surgery. Of the 1000 vNOTES cases performed during this study period, hysterectomy (73%) was the most common followed by adnexal surgery (18%) and salpingectomy (4%). The mean age of the patient cohort was 46 yrs of age (22-83) and mean BMI, 26 kg/m 2 (16.5-52). There was a conversion rate of 0.4% (4 cases), 3 to conventional laparoscopy and 1 to laparotomy. The mean operating time was 42 minutes (14-250 minutes). The total complication rate was 3.9% (39) of which 1% (10) was intraoperative complications and 2.9% (29) were post-operative complications. When the hysterectomy cohort was sub analyzed, the total complication rate was 5.2% in this group (intraoperative 1.4% and post-operative 3.8%) with only a 0.4% complication rate in the non-hysterectomy sub-group. Of the complications in the hysterectomy group there were 9 cystotomies (1.2%). The mean specimen weight for all hysterectomies was 172 g (20-3361 g) with an average operating time of 46 minutes (20-250). CONCLUSION: The perioperative outcomes of this large vNOTES case series for benign gynaecological indications is comparable to other vNOTES procedures reported in the literature apart from the risk of cystotomy which is a hysterectomy specific risk. The outcomes are that of a single high-volume surgeon incorporating cases within his respective learning curve of the surgical technique and as such should be interpreted accordingly. Since 2015 the International NOTES Society has initiated a prospective complication database where all vNOTES surgeons are invited to register their cases.
