Interventional postoperative manipulation of the common bile duct is usually performed for removal of retained calculi via T-tube or surgical cholecystostomy tracks. The removal of foreign bodies from the gallbladder and common bile duct in dogs via cholecystostomy tracks using interventional radiology techniques is described as an alternative to surgery.
