Abstract Background Pancreatic duct obstructions are common in patients with pancreaticoduodenectomy. However, it is often neglected in follow up. This study was to review the outcomes of pancreatic duct obstruction and explore the prevention of pancreatic duct obstruction. Methods A retrospective analysis of 78 patients undergoing pancreaticojejunostomy without reccurence of disease within 24 months between 2004 and 2014. Pancreatic duct obstruction and long-term pancreatic complications were analysed. Results Twenty-five patients developed pancreatic duct obstruction following pancreaticojejunostomy, 13 of whom were found to have long-term pancreatic complications. The presence of pancreatic duct obstruction and early pancreatic obstruction were associated with long-term pancreatic complications, respectively (p = 0.002, p = 0.002). There are 10 patients with pancreatic duct stent more than 24 months, the postoperative median pancreatic parenchymal thickness in these 10 patients (17.1 mm, range 8.0 to 24.7 mm) was not significantly change than the median in them preoperative (16.4 mm, range 7.2 to 24.7 mm; p = 0.747). All of them have no long-term pancreatic complications, though the difference was not significantly (p = 0.068). Conclusions Early pancreatic duct obstruction is associated with postoperative pancreatic long-term complications. Sustained internal pancreatic stent may improve pancreatic duct obstruction.
