Abstract
A 63-year-old female was admitted for the treatment of cholangitis. She had beenseen under the elsewhere diagnosis of Mirizzi syndrome where insertion of an endoscapicbiliary stent could not prevent obstruction of the previous stmt and caused her cholangitisrecurrence. We performed percutaneous transhepatic biliary drainage approaching B30fthe liver and fractured a stone 30 mm diameter in the bile duct using an electrohydrauliclithotriptor under cholangioscopy. We then found a biliobiliary fistula connecting thecommon hepatic duct and the cystic duct. We also performed endoscopic resection of asmall polyp with a stalk 2 mm in diameter locating in the orifice of the fistula near theopening of the common hepatic duct. The polyp was histologically diagnosed as aninflammatory polyp.
