The implication of ectopic opening of the pancreaticobiliary duct in the diagnosis and treatment of cholangiopancreatic disease / 中华消化杂志

ABSTRACT

Objective To discuss the implication of ectopic opening of the pancreaticobiliary duct in the performance of cholangiopancreatography (ERCP) and the diagnosis and treatment of cholangio-pancreatic disease. Methods We summarize the data of 1000 cases of ERCP in the past four years. Five patients were found with ectopic opening of the pancreaticobiliary duct. The positions, characteristics of ectopic opening and the characteristics of the mucosa disease around the ectopic papilla and cholangio-pancreatic disease were analyzed. Results In the 5 patients with ectopic opening of the papilla, one had the opening in the pyloric channal, two in the duodenal bulb, the other two in the distance of the descending part of duodenum. Mucosa erosion was found in the patients with ectopic opening in the pyloric channal and in the duodenal bulb. Conclusion The ectopic opening of the pancreaticobiliary duct may affect the finding of the papilla, but may not affect the performance of ERCP. The incidence of the cholangiopancreatic disease and the mucosa disease around the ectopic papilla will increase in the patients with ectopic opening.
