Abstract

Double common bile duct (DCBD) is a rare congenital anomaly among biliary anomalies. The anomaly has an important clinical implication because of its association with anomalous pancreaticobiliary ductal union (APBDU) and upper gastrointestinal cancers. In addition, if one of the two common bile ducts is mistaken for the cystic duct during surgery, bile duct injury is likely to occur. Treatment depends on the coexistence of concomitant cancer and APBDU. A 54-year-old male diagnosed of gastric cancer was referred for surgery. During surgery, we incidentally detected bile leak from the tubular structure around the hepatoduodenal ligament. We performed intraoperative cholangiogram by cannulizing into the tubular structure, and confirmed the tubular duct as the accessory bile duct with an ectopic drainage into the stomach, which was connected to the proximal common bile duct. In this study, we report a rare case of DCBD with an ectopic drainage into the stomach and review the literature.

Figure

• 

  Fig. 1 Operative finding. There is a tubular structure on the left side of the hepatoduodenal ligament which was ligated on the stump (arrow).

• 

  Fig. 2 Intraoperative cholangiogram shows that the accessory common bile duct was connected with the proximal common bile duct and linked with the left intrahepatic duct.

• 

  Fig. 3 Specimen shows that the accessory common bile duct (ACBD) opening is located in the lesser curvature of the stomach, and ACBD site is away from the gastric cancer lesion of the antrum.
