Abstract
The patient was a 75-year-old man who had been diagnosed as having double gallbladder 18 years previously. He complained of worsening epigastralgia for one year. Abdominal CT showed the accessory gallbladder embedded within the hepatic hilus. The gallbladder lumen was filled with biliary sludge. ERCP revealed an accessory gallbladder communicating with the left hepatic duct. We performed cholecystectomy for both gallbladders. After resecting the main gallbladder, we found the accessory gallbladder between the left and right hepatic ducts. It was difficult to disrupt the adhesions between the accessory gallbladder and hepatic ducts. Therefore, we incised the gallbladder, and resected the gallbladder wall to the maximum extent possible. We found an abnormal node in the resected accessory gallbladder wall. Intraoperative rapid diagnosis revealed the node to be an adenocarcinoma. The hepatic ducts and common duct wall were hard, indicating direct invasion of the carcinoma from the accessory gallbladder. Double gallbladder occurs in about one per 4000 births. Thus, double gallbladder with adenocarcinoma is very rare. We report our patient with reference to the relevant literature.
