Objective To explore the clinical value of the improved style of pancreatodeodenectomy. Methods Retrospective analysis the data of 111 cases of pancreatodeodenectomy. Forty-one cases of 111 cases were performed the modified Whipple pancreatic jejunal anastomosis， which reconstruction residual pancreatic duct jejunum into the intestinal mucosa sets of accurate end to side anastomosis type （modified group）. Another 70 cases were performed the conventional Whipple pancreatic jejunal anastomosis， which classic lines set into the pancreas jejunum anastomosis （conventional group）. The incidence rate of pancreatic fistula after operation were compared in two groups. Results The postoperative recovery in modified group was smooth， and there was no case of pancreatic fistula. Thirteen cases （18.57%） had pancreatic fistula in conventional group. The difference of incidence rate of pancreatic fistula between two groups was statistically significant （P＜0.05）. The difference in other complications such as gastrointestinal bleeding， delayed gastric emptying， biliary fistula， abdominal infection， lung infection， and wound infection were no statistically significant （P＞0.05）， and the difference of survival rate was also no statistically significant （P＞0.05） in two groups. Conclusions Pancreatic duct jejunum end to side into the mucous membrane of the mucosal anastomosis sets of pancreatodeodenectomy can significantly prevent pancreatic fistula， it is worth to promote the use in clinical work.
