 We report a case of a gallbladder hyperplastic polyp complicated by a communicating accessory bile duct (CABD). A 59-year-old woman was referred to our hospital for an elevated lesion in the gallbladder. Ultrasonography detected a 12-mm gallbladder polyp, which did not show any potential for malignancy. Endoscopic retrograde cholangiography (ERC) revealed that the CABD was connected to the right hepatic duct and the common bile duct. The cystic duct was observed to be attached to the CABD, which was not identified clearly on computed tomography with drip infusion cholangiography (DIC-CT). In our case, the cystic duct was not involved in a circuit formed by the CABD, common bile duct, and right hepatic duct. To preoperatively determine CABD, we performed laparoscopic cholecystectomy and carefully preserved the CABD. Histopathologic diagnosis was benign hyperplastic polyp of the gallbladder. CABD is a very rare biliary condition. An anomalous biliary system is a risk factor for intraoperative biliary injury. Surgeons must be careful while examining the biliary system by cholangiography such as DIC-CT or ERC before laparoscopic cholecystectomy.
