Pancreatic and biliary duct fistula are the most severe and common complication following pancreatoduodenectomy. To prevent this complication, anastomosis should be appropriately performed and drainage of the pancreatic and bile duct is crucial. For proper drainage, the authers designed a cross-shaped tube for both the pancreatic and bile duct drainage, which has been practised on 16 patients with no pancreatic and biliary fistula happened. This new model combines the internal and external pancreatic drainages with biliary T-tube drainage and gives better drainage in practice so that the leakage might be lessened.
