Common bile duct (CBD) stones are prevalent in 11% to 21% of patients with gallstones and can cause various clinicalmanifestations, from biliary colic to biliary sepsis. The treatment of choice is endoscopic retrograde cholangiopancreatography,but approximately 5% to 10% of CBD stones are difficult to remove using these conventional endoscopic methods. Althoughpercutaneous transhepatic cholangioscopy and lithotripsy can be used as an alternative, it can be technically demanding and riskyif the intrahepatic duct is not dilated. We report a case of a large CBD stone that was successfully removed using percutaneoustranscholecystic cholangioscopy.
