Although the presence of foreign bodies in the common bile duct and T-tube tract is uncommon, it is because of recent developments in endoscopic biliary intervention and percutaneous choledochoscopic procedures that they are found with increasing frequency in the biliary tree. We report two cases in which foreign bodies in the biliary tree were successfully removed using the percutaneous gooseneck snare technique. In one patient a plastic biliary stent was malfunctioning and could not be removed under endoscopic guidance, while in the other, a plastic guidewire had been inserted into the T-tube tract during percutaneous choledochoscopy for the treatment of a common bile duct stone.
