Pancreatic sphincterotomy and pancreatic endoprosthesis.
Recently, endoscopic sphincterotomy (EST), developed as a treatment of bile duct stone or papillary stenosis, has been used for transpapillary biliary drainage in cases of extrahepatic biliary stenosis. For the nonoperative treatment of chronic pancreatitis, we have developed this procedure into a technique for opening the pancreatic duct orifice. Pancreatic sphincterotomy was performed successfully in 10 out of 13 cases with chronic pancreatitis and improved the clinical symptoms in 9 cases. Moreover, in 3 cases we succeeded in inspecting the intrapancreatic duct by peroral pancreatoscopy, and in removing stones from the main pancreatic duct in 2 cases in this series, using the basket. Also through the opened pancreatic orifice, a pancreatic endoprosthesis was placed endoscopically into the main pancreatic duct in 3 cases to improve pancreatic drainage. This report discusses method, evaluation, and complications of pancreatic sphincterotomy in the endoscopic treatment of chronic pancreatitis, and describes successful cases of the basket removal of pancreatic stones and the placement of pancreatic endoprosthesis through the opening of the pancreatic orifice.
