Abstract: Objective To summarize the application of seven-stitch definitive suture in total laparoscopic total gastrectomy with esophagojejunostomy. Methods From March 2021 to July 2022, 14 patients with early and advanced upper gastric cancer were treated with total laparoscopic total gastrectomy, esophagojejunal anastomosis to reconstruct digestive tract, and manual anastomosis was optimized by seven-stitch definitive suture method for anastomosis. The operative time, intraoperative blood loss, intraoperative anastomosis reconstruction cost, postoperative complications, postoperative pathology and prognosis were analyzedResults The average operation time of the 14 patients was 300 minutes, the average intraoperative blood loss was 110ml, and the average cost of consumables for resection and reconstruction was 16767 yuan. Of the 14 patients, 3 had perioperative complications. Conclusion Compared with instrument anastomosis, seven-stitch definitive suture avoids the risk of excessive tissue anastomosis tension and tissue compression caused by individual differences, does not increase the incidence of postoperative complications, reduces the medical cost of patients, and safely and effectively optimizes the process of endoscopic manual anastomosis.
