Using the endoscope, the doctor places a tiny piece of plastic or metal that looks like a straw in a narrowed pancreatic or bile duct to keep it open.
Small metal or plastic tubes can be inserted through endoscopes to maintain open areas of narrowing that may occur in different parts of the bowel, pancreas, or biliary tree.  These tubes are called stents.
