Brief summary: Natural Orifice Specimen Extraction Surgery (NOSES), which involves obtaining specimens from the abdominal cavity without any incisions, has attracted much attention in recent years, and it has been widely popularized in the treatment of rectal cancer because of its postoperative non-incision, advantages of less trauma, quicker recovery, and postoperative aesthetics. Anastomotic fistula is a serious complication of rectal cancer surgery. For patients at high risk of anastomotic fistula, prophylactic ileostomy is often performed intraoperatively to divert feces and protect the anastomosis. For such patients, rectal anterior resection surgery with specimen extraction via stoma (NOSES with specimen extraction via stoma) is usually performed, borrowing a prophylactic stoma incision to retrieve the specimen, and also realizing the absence of additional abdominal incision. However, this procedure is prone to stoma infection and has a high complication rate (20-40%), which limits the popularization of NOSES surgery and is an urgent clinical problem. Our center has proposed a new stoma closure method (Dumpling Suture Method), which reduces the size of the incision by folding the suture to achieve the effect of hiding the skin incision and reduce stoma infection. In our previous study, 17 cases of the new procedure were completed in our center, and 25 patients with stoma closure by the traditional method were included in the same period for control purposes. After six months of follow-up, we found that the "dumpling suture method" significantly reduced the incidence of stoma complications compared with the traditional suture method (5.8% vs. 36%), and no additional adverse effects were observed. This is a single-center, open-label, randomized, parallel-controlled clinical study. The primary endpoint is stoma complication rate within 30 days postoperatively. In this study, we aim to evaluate the efficacy and safety of the "dumpling suture method " compared with the traditional stoma suture in reducing postoperative stoma complications through a randomized parallel controlled clinical trial, which is of great significance for the improvement of the rectal NOSES procedure and the reduction of the incidence of stoma complications.
