Bile duct stones are typically removed using endoscopic retrograde cholangiopancreatography (ERCP), a minimally invasive procedure that combines x-ray and upper endoscopyâan exam of the upper gastrointestinal tract, consisting of the esophagus, stomach and duodenum (the first part of the small intestine)âusing an endoscope, which is a lighted, flexible tube, about the thickness of a finger.
A balloon catheter is inserted and swept down past the biliary or pancreatic duct calculus (stone). The balloon is inflated and the stone is extracted by slow withdrawal of the balloon catheter. Alternatively, a basket extraction can be performed. The basket extraction device is inserted, the calculus is trapped within the device, and the basket is then slowly withdrawn. One or more calculi may be removed during this procedure.
