A 48-year-old woman, who had occasional right hypochondralgia for one year, consulted a local medical doctor. Abdominal ultrasonography was performed and showed dilatation of the common bile bile duct. There after, she was referred to our hospital, where endoscopic ultrasonography and endoscopic retrograde cholangiopancreatography were performed. A diagnosis of congenital dilatation of bile duct was made, but pancreaticobiliary maljunction was uncertain. Resection of the dilated bile duct was carried out. To determine the cut end of the distal bile duct, intraoperative cholangiography was performed, and showed no sign of pancreaticobiliary maljunction. The level of amylase value in bile juice of the bile duct was normal as 32IU/l.This case is an interesting example of the relationship between congenital dilatation of bile duct and pancreaticobiliary maljunction.

Key words
