Abstract: Objective To explore the clinical application effects of Chen's pancreatojejunostomy in laparoscopic pancreaticoduodenectomy.Methods Clinical data of 176 patients who underwent laparoscopic pancreaticoduodenectomy in Xiangyang Central Hospital from January 2019 to December 2024 were retrospectively analyzed.According to the methods of intraoperative pancreatojejunostomy,the patients were divided into two groups,the research group(102 cases) using Chen's pancreatojejunostomy,and the control group(74 cases) using duct-to-mucosa pancreatojejunostomy.The two groups were compared on clinical indicators,including operation time,pancreatojejunostomy time,intraoperative blood loss,incidence of postoperative complications,length of hospital stay,and 30-day postoperative mortality rate.Results All 176 patients successfully underwent laparoscopic pancreaticoduodenectomy.There were no statistically significant differences between the two groups in intraoperative blood loss,biochemical leakage,abdominal bleeding,upper gastrointestinal bleeding,delayed gastric emptying,bile leakage,abdominal infection,and 30-day postoperative mortality rate(P>0.05).The pancreatojejunostomy time[(22.33±5.95)min] and operation time[(334.60±66.42)min] in the study group were significantly shorter than those in the control group[(30.70±5.50)min] and [(414.46±60.96)min],with statistically significant differences(P<0.05).Two groups of patients did not develop grade C pancreatic fistula.The incidence of grade B pancreatic fistula in the study group(5.88%) was significantly lower compared to the control group(16.22%),and this difference was statistically significant(P<0.05).Additionally,The postoperative hospital stay of the study group patients[(17.10±6.89)days] was significantly shorter than in the control group[(20.88±8.40)days],with a statistically significant difference(P<0.05).Conclusion Chen's pancreatojejunostomy is a feasible,safe,and effective procedure in laparoscopic pancreaticoduodenectomy,which can shorten the pancreatojejunostomy time,reduce the incidence of postoperative pancreatic fistula,and decrease the length of hospital stay.
