A 50-year-old man, with a complaint of fever and epigastralgia, was admitted to the Yamaga City Hospital. Choledocholithiasis and stenosis of the lower part of choledochus were pointed out. Cholecystectomy, choledocholithotomy and papilloplasty were performed and the choledochotomy closed over a T-tube. T-tube cholangiograms, after operation, revealed stenosis, negative shadow and abnormal branching of the left intrahepatic bile duct. Then, the lateral segmentectomy of the liver was done. But the negative shadow didn't disappear . With further examination, we could find the accessory bile duct in the retroperitoneal space. Cholangiogram, from this accessory bile duct, revealed patency of this bile duct into the left intrahepatic bile duct and the duodenum. A final diagnosis of duplication of the common bile duct was established. We collected Japanese cases of this anomaly and discussed a classification of the disorder.
