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.
During this test, stones can be removed from the bile duct, tumors can be biopsied and the obstruction can be relieved. Alternatively, an MRCP (MRI scan of the bile ducts) can further determine the cause of dilated bile ducts but is of diagnostic value only.
