Case Report of a Double Common Bile Duct with Gallstone Cholecystitis / 대한내과학회지

ABSTRACT

Anatomical variation in the bile duct system is relatively common. Nevertheless, a double common bile duct is an extremely rare asymptomatic variant. Recognition of this anomaly is important clinically, because it can lead to complications, including choledocholithiasis, cholangitis, pancreatitis, and upper gastrointestinal malignancies. A correct diagnosis of this rare anomaly is also important because complications can occur in surgery if the anomaly is not recognized preoperatively. Recently, we encountered a very rare case of a double common bile duct associated with gallstone cholecystitis. A 33-year-old female was admitted to our hospital complaining of epigastric pain after meals. She had single biliary drainage from double common bile ducts with communicating channels. We report the case and review the literature on double common bile ducts.
