Abstract
-
The common bile duct classically enters the posteromedial aspect of the second part of the duodenum through an oblique, 1 to 2 cm long intramural tunnel. Some case reports of the common bile duct emptying into other sites including the fourth part of the duodenum, the pyloric canal, stomach and duodenal bulb have appeared in the literature. We report a case of a 40-year-old man who showed anomalous drainage of the common bile duct into the duodenal bulb presenting with obstructive jaundice and duodenal ulcer. This patient required choledochoenteric anastomosis to relieve obstructive jaundice and abdominal pain. We report the case with a review of other cases in Korean literature.
