Three Cases of Anomalous Drainage of Common Bile Duct into the Duodenal Bulb / 대한소화기내시경학회지

ABSTRACT

Classic anatomical descriptions state that the common bile duct enters to the medial border of the second part of duodenum. Isolated case reports of the common bile duct in other sites, including the fourth part of duodenum, the pyloric canal, stomach, and the duodenal bulb, have appeared in the literature. We report three cases of anomalous drainage of the common bile duct into duodenal bulb, which caused recurrent cholangitis and peptic ulcer. All patients required choledochoenteric anastomosis to relieve their syrnptoms.
