Mirizzi syndrome (MS) is characterized by common hepatic duct obstruction due to mechanical compression and surrounding inflammation by a gallstone impacted in the cystic duct (type I) or at the gallbladder neck (type II). Preoperative diagnosis of the syndrome is mandatory and associated with a decrease of complication rate of surgical management. Endoscopic therapies like ERCP with lithotripsy or endoscopic extraction of cystic duct calculi followed by laparoscopic cholecystectomy have been described. Here we report successful endoscopic stone-clearance using double-cannulation and large balloon dilatation of the papilla for giant biliary stone impacted in the cystic duct inserted low in the common hepatic duct causing type I MS.
