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.
If you have stones in the bile duct as well as your gallbladder, you may require removal of both the duct stones and your gallbladder. In some cases it is best to remove the stones in the bile duct before your operation using an endoscope.
