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.

In serious cases, the common bile duct can be surgically moved so that it empties further down the small intestine.ile duct obstruction is a blockage in the tubes that carry bile from the liver to the gallbladder and small intestine.
