Abstract    Objective    To investigate the effect of pancreatic duct stent internal versus external drainage with pancreaticojejunostomy on the early curative effect after pancreaticoduodenectomy (PD). Methods    The clinical data of 118 cases of PD performed from October 2008 to February 2013 in the Affiliated Hospital of Inner Mongolia Medical University were analyzed retrospectively. A total of 96 case were adopted in the study including internal stent drainage in 54 cases（56.2%）and external stent drainage in 42 cases (43.8%). The two groups were compared in preoperative status，operative duration，postoperative stay，mortality rate and the morbidity of pancreratic fistula as well as other complications. Results    There are 14 case (25.9%) of pancreatic fistula in internal stent group and 4 case (9.5%) of pancreatic fistula in external stent group with significant statistical difference (P=0.041). There was no significant difference in demographic data，presence of comorbid illnesses，underlying pathologies，pancreatic consistency，duct diameter and others complications (biliary fistula，intestinal fistula，reoperation，wound infection，lung complication，death, etc.) between the two groups (P>0.05). Conclusion    Pancreatic duct stent external drainage can reduce the morbidity of pancreatic fistula more effectively than internal drainage, which is worthy of application.
