Metal stenting is a minimally invasive procedure used to maintain the patency of hollow structures in the body, such as the bile ducts, esophagus, or airways, when narrowed or blocked due to benign or malignant conditions. In gastroenterology, self-expanding metal stents (SEMS) are widely used to treat biliary, esophageal, and gastrointestinal strictures.
