Background Endoscopic treatment through the minor papilla is well known in patients with pancreas divisum. However, there are few data concerning endoscopic minor papilla interventions in patients without pancreas divisum when access to the main pancreatic duct via the major papilla is technically difficult. Methods Records for 213 patients without pancreas divisum who, from April 2001 to June 2003, underwent ERCP for various pancreatic diseases were retrospectively reviewed. Patients were included if they had endoscopic interventions via the minor papilla because access through the major papilla was not possible. Observations Minor papilla papillotomy or fistulotomy with endoscopic interventions was successful in 10 (91%) of 11 patients. Of these 10 patients, 9 had chronic pancreatitis and one had pancreatic ductal leak from previous pancreatic surgery. The reasons for the inability to access the main pancreatic duct to the tail of the gland via the major papilla included a distorted course of the main pancreatic duct (n=5), impacted stone (n=5), and stricture (n=8). In 8 patients, there were two causes. No complication related to the minor papilla interventions was observed in any patient. Conclusions Endoscopic minor papilla interventions are technically feasible in patients with pancreatic diseases but not pancreas divisum when access to the main pancreatic duct via the major papilla is not possible.
