Abstract

The common bile duct normally enters the posteromedial aspect of the second part of the duodenum. However, anomalous drainage of the common bile duct into the stomach, pyloric channel, duodenal bulb and fourth portion of the duodenum has been reported in the literature. An anomalous pancreatic duct, with ectopic drainage of the common bile duct, is particularly rare. Herein, we report the case of a 69-year-old woman who showed pancreatic ductal variation and anomalous drainage of the common bile duct into the duodenal bulb. The patient required a cholecystectomy and choledochoenteric anastomosis to relieve the obstructive jaundice and abdominal pain. (Korean J Gastrointest Endosc 2006;32:352⁣356)
