Can biliary and pancreatic plastic stents cause enormous amounts of pain?

Adhesions can: A stent is used to keep open the soft tissue ducts. You should get relief from pain as the blockage of flow through the duct is relieved. The illness that made it necessary to insert the stent may be causing the painful areas. Scar tissue (adhesion) can occur after stent placement. Adhesions are like a spider web. They thicken and compress soft tissues as a nerve. See your doctor asap.
