Analysis and suggestions on the complications in 2000 cases of transvaginal natural orifice transluminal endoscopic surgery: Can it be a conventional surgery?

Objective: To reflect on the complications of transvaginal natural orifice transluminal endoscopic surgery (vNOTES), identify the corresponding risk factors, and provide caution to surgeons when performing this novel surgery. Methods: A retrospective study was carried out among 2000 patients in our hospital who underwent vNOTES between May 2019 and May 2022. Perioperative complications were stratified in chronological order and divided into those developed while establishing the vNOTES approach, during surgery, postoperatively, and 1 month after discharge. The complications were classified based on the Modified Clavien‐Dindo classifications. The causes of each type III/IV complication were analyzed. Results: Of the 2000 patients, 88 (4.4%) experienced complications, which is not higher than that reported in laparoendoscopic surgery in previous studies. Grade I, II, III, IV, and V complications developed in 19 (0.95%), 57 (2.85%), 11 (0.55%), 1 (0.05%), and 0 (0%) patients, respectively. Complications were developed while establishing the approach platform, during the surgery, postoperatively, and within 1 month after discharge in 5 (0.25%), 30 (1.50%), 50 (2.50%), and 3 (0.15%) patients, respectively. Eight patients (0.4%) underwent conversion, including five cases of rectal injury repair. Conclusion: The summarized suggestions were divided into three levels. Considering the security and effectiveness of vNOTES, it can be routinely used in various gynecologic operations. However, surgeons should focus on preoperative evaluation, strictly conduct preoperative disinfection, conform to prompt conversion during surgery, call for the presence of experienced doctors, and have routine use of antibiotics to prevent postoperative infections. Trial Registration: ChiCTR2100053483. SYNOPSIS: vNOTES can be routinely used in gynecologic operations, but preoperative evaluation and disinfection, prompt conversion during surgery, and routine antibiotic use are essential.
