Abstract：Objective To evaluate the safety and efficacy of the modified Q-type purse-string suture and embedding method for the duodenal stump in laparoscopic radical gastrectomy for gastric cancer.Methods A retrospective analysis was conducted based on the clinical data of 432 patients who underwent laparoscopic radical gastrectomy for gastric cancer at Subei People's Hospital between January 2020 and June 2023.All patients had duodenal stump reinforcement during surgery.The patients were divided into the Q-type suture group(262 cases)using the modified Q-type purse-string suture and embedding method,and the interrupted suture group(170 cases)using the traditional interrupted suture embedding method.The clinicopathological characteristics,perioperative data,and postoperative complications of the two groups were compared.Results There were no statistically significant differences in the clinicopathological characteristics between the two groups,making them comparable.The Q-type suture group showed superior performance than the interrupted suture group in purse-string suture time((4.1±1.8)min vs.(9.3±1.4)min,P=0.001),purse-string suture success rate(90.1％vs.78.1％,P=0.001),and purse-string suture satisfaction rate(95.4％vs.89.9％,P=0.026).No patients in the Q-type suture group experienced duodenal stump leakage(DSL),while two patients in the interrupted suture group experienced DSL and the difference was not statistically significant(P＞0.05).There were no DSL-related reoperations or deaths in the two groups.No significant differences in other postoperative complications between the two groups were observed(P＞0.05).Conclusion The modified Q-type purse-string suture and embedding method for duodenal stump reinforcement is simple and safe,reduces operation time,improves the success rate and satisfaction rate of purse-string sutures,and tends to lower the incidence of duodenal stump leakage without increasing the risk of related reoperations.
