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.
Bile Duct Stones. Bile duct stones are gallstones in the bile duct. They can start in the gallbladder and migrate into the bile duct or they can form in the bile duct itself. The stones can become lodged in the bile duct, causing a blockage. At the Bile Duct and Pancreatic Diseases Program, part of the University of Michiganâs Division of Gastroenterology, our multidisciplinary team provides the newest in minimally invasive treatments for bile duct stones.
