A Case of Anomalous Termination of the Common Bile Duct and the Pancreatic Duct into the Duodenal Bulb, Associated with Common Bile Duct Stones / 대한소화기내시경학회지

ABSTRACT

Usually, the papilla of Vater is located in the midportion or the distal half of the descending duodenum. Isolated cases of common bile duct termination in other sites, including the fourth portion of the duodenum, the pyloric ring, the duodenal bulb and the stomach, have been reported. A case is here in reported involving abdominal pain in the right upper quadrant area, in which an ERCP demonstrated an anomalous termination of the common bile duct and pancreatic duct into the duodenal bulb separately. This anomaly was associated with a bile duct dilatation and single common bile duct (CBD) stone. Trial of CBD stone removal during an ERCP failed. The patient's condition improved after a cholecystectomy and choledochojejunostomy.
