Abstract
A 61-year-old man was admitted to our hospital due to upper abdominal pain. His initial diagnosis was acute cholangitis due to stones in the gallbladder and common bile duct (choledocholithiasis). After admission, he underwent endoscopic retrograde cholangiography to establish biliary drainage. CT indicated a cholecystohepatic duct connecting segment V of the liver directly to the body of the gallbladder. This cholecystohepatic duct was dilated due to the presence of gallstones that blocked the cystic duct. At cholecystectomy, the cholecystohepatic duct was transected at the joint of the gallbladder. However, the residual cystic duct was long and we could perform a side-to-side anastomosis of the cystic duct and the B5-cholecystohepatic duct with stent placement. The postoperative course was uneventful, and no biliary leakage was detected at the 1-year follow-up examination.
