Abstract´╝Ü Objective:To study the safety and feasibility of total hysterectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) and transumbilical laparoendoscopic single site surgery (TU-LESS).Methods:The study was a retrospective cohort analysis. In West China Second University Hospital, from October 1, 2018 to June 30, 2019, the patients with an indication for hysterectomy due to benign uterine diseases were enrolled, and were grouped by the surgical procedure. Various post-operative surgical outcomes, including the success rate of operation, uterine volume, operative time, blood loss, intraoperative complications, postoperative complications, the first time of flatus, the preserved time of catheter after operation, and the length of hospitalization were measured. The data were assessed by the software of SPSS.Results:Totally 30 patients were included in the vNOTES group, and 77 patients were included in the TU-LESS group, all of the procedures were completed successfully without conversion to traditional multiport laparoscopy or laparotomy. Non differences were observed between two groups, including uterine volume [(165±36) vs (235±38) cm 3, P=0.243], operation time [(150±41) vs (169±48) minutes, P=0.063], blood loss [(54±15) vs (54±14) ml, P=0.985], the rate of intraoperative complications [3% (1/30) vs 4% (2/77), P=1.000], the rate of postoperative complications [13% (4/30) vs 4% (3/77), P=0.095] and the rate of bilateral salpingo-oophorectomy [50% (15/30) vs 31% (24/77), P=0.069]. Patients in the vNOTES group had significantly less recovery time of intestine function [(1.7±0.5) vs (2.3±0.6) days, P=0.001], shorter time of indwelling catheter [(1.9±0.4) vs (2.3±0.6) days, P=0.004], and duration of hospitalization [(3.2±0.8) vs (3.6±0.9) days, P=0.045]. Conclusions:vNOTES and TU-LESS are both safe and feasible for total hysterectomy. Compared with TU-LESS, vNOTES may be a promising approach with earlier recovery, less injury and better cosmetic.
