[Application of "modified double pocket suture" pancreatoenterostomy in laparoscopic pancreatoduodenectomy]

Objective: The purpose of this study was to explore the value of the "improved double purse-string suture method" for pancreatojejunostomy in laparoscopic pancreaticoduodene-ctomy. Methods: The clinical data of 273 patients who underwent laparoscopic pancreaticoduode-nectomy in the Department of Hepatobiliary and Pancreatic Surgery of the First Hospital of Jilin University from January 2021 to May 2022 were retrospectively analyzed. According to the method of pancreaticoenteric anastomosis, the patients were divided into two groups: the "improved double purse-string suture method" group and the "Hong's one-stitch method" group. Results: The "improved double purse-string suture method" for pancreaticoenteric anastomosis was performed in a total of 189 patients, including 107 males and 82 females, with a mean age of (59.6±10.2) years. The "Hong's one-stitch method" group" was performed in a group of 84 patients, including 52 males and 32 females, with a mean age of (60.8±9.3) years.The results showed that the "improved double purse-string suture method" group had a lower incidence of postoperative pancreatic fistula (6.88% vs 8.33% for grade B fistula, and 1.58% vs 2.38% for grade C fistula) and a shorter anastomosis time [(25.25±4.73) min vs (25.76±6.71) min] than the "Hong's one-stitch method" group. There was no statistically significant difference between the two groups in terms of postoperative biliary fistula, abdominal bleeding, delayed gastric emptying, and other complications (P>0.05). Conclusion: The "improved double purse-string suture method" for pancreatojejunostomy is safe and feasible in laparoscopic pancreaticoduodenectomy.
