There are many variations in the biliary system, and one of these is an accessory hepatic duct. A case of a comparatively rare accessory hepatic duct was experienced, and is reported. The patient was a 38 year-old woman who was administered an analagesic at another hospital for right hypochondralgia on January 2,1989. However, the pain reappeared in the same place on January 6 and she was admitted to the authors' department as an emergency patient. On an abdominal ultrasonogrm, many strong echoes were observed in the gall bladder, and choleithiasis was diagnosed. By endoscopic retrograde cholangiopancreatography a cystic duct opening into an accessory hepatic duct was found. Cholecystectomy from the cystic fundus was performed. After it was confirmed by operative cholangiography that there was no damage to the accessory heptic duct, choledochotomy was performed. This accessory hepatic duct was a comparatively rare case of type II according to the classification of Miyakawa.
