Objective:To evaluate A modified Blumgart pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy.Methods:The clinical data of 81 patients undergoing laparoscopic pancreaticoduodenectomy in Zhengzhou University Affiliated Cancer Hospital from Jan 2019 to Jan 2022 were retrospectively analyzed. Among them, 26 patients underwent modified Blumgart anastomosis and 55 underwent conventional Blumgart anastomosis.The data of demographics, liver function, pancreatic texture, operational result and complications were compared between the two groups.Results:The preoperative data (body mass index, preoperative albumin, prealbumin, transaminase, total bilirubin) between two groups were comparable ( P>0.05). There was no significant difference in pancreatic texture, pancreatic duct diameter and intraoperative blood loss between the two groups ( P>0.05). The modified group had shorter total operation time ( P<0.05), shorter pancreaticojejunostomy time ( P<0.05), shorter postoperative hospital stay ( P<0.05). The incidence of total pancreatic fistula and biochemical fistula in the modified group were lower than those in the conventional group ( P<0.05). There was no significant difference in the incidence of B/C grade pancreatic fistula and bile leakage, postoperative bleeding, infection and delayed gastric emptying between the two groups ( P>0.05). Conlusions:The modified Blumgart pancreaticojejunostomy during laparoscopic pancreaticoduodenectomy is safe, easy to do and time saving. While the incidence of postoperative pancreatic fistula with clinical significance　and other major complications were similar to traditional Blumgart procedure.
