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 planned to recruit 66 patients randomized in a 1:1 ratio to the trial and control groups. The primary endpoint is stoma complication rate at 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.

Arm Intervention/treatment
Experimental: "Dumpling suture" for ileostomy
The stoma is fixed with sutures in a skin fold method, and the incision is progressively reduced in a process similar to the process of folding and pinching the Chinese small dumplings. This procedure may reduce stoma complications by progressively reducing the incision and realizing the effect of hiding the skin incision.
 Procedure: Suturing of ileostomy using "Dumpling suture method"
Suturing of ileostomy using "Dumpling suture method"
Traditional suture for ileostomy
The stoma was fixed at the skin using traditional sutures. The incision is narrowed by 2-3 interrupted sutures at the distal and proximal ends of the skin incision on the abdominal wall. The stoma is then fixed at the right lower abdominal incision with sutures.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Complication rate of stoma [ Time Frame: Day 30 after surgery ]
    Observe and assess for stoma complications


Secondary Outcome Measures :
  1. Stoma DET（Discoloration，Erosion and Tissue overgrowth） score [ Time Frame: Day 30 after surgery ]
    Measure the state of the skin around the stoma and the corresponding lesion area, ranging from 0-15, higher scores mean a worse outcome of stoma

  2. Stoma Pain Score [ Time Frame: Day 30 after surgery ]
    Measurement of stoma pain level using numerical rating scale，ranging from 0-10, higher scores mean a worse outcome of pain

  3. Quality of life scale score for patients with stoma [ Time Frame: Day 30 after surgery ]
    Measurement of quality of life for patients with stoma using City of Hope Quality of Life-Ostomy Questionnaire (CHO-QOL-OQ), ranging from 0-3200, higher scores mean a worse outcome of quality of life
