Self-Expanding Metal Stents Esophageal and Colonic

Self-Expanding Metal Stents (Esophageal and Colonic)

A self-expanding metal stent (SEMS) is a metal tube or stent that opens part of the gastrointestinal tract. The stent assists in the movement of food, stool or liquids. SEMS are inserted through the mouth or colon with an endoscope, a flexible tube with a small camera or an X-ray-guided fluroscope. SEMS are used in cancer treatment and can unblock the colon, esophagus, bile duct and duodenum.
