A self-expandable metallic stent (or SEMS) is a metallic tube, or stent that holds open a structure in the gastrointestinal tract to allow the passage of food, chyme, stool, or other secretions related to digestion. Surgeons insert SEMS by endoscopy, inserting a fibre optic camera—either through the mouth or colon—to reach an area of narrowing. As such, it is termed an endoprosthesis. SEMS can also be inserted using fluoroscopy where the surgeon uses an X-ray image to guide insertion, or as an adjunct to endoscopy.

  • A self-expandable metallic stent (or SEMS) is a metallic tube, or stent that holds open a structure in the gastrointestinal tract to allow the passage of food, chyme, stool, or other secretions related to digestion. Surgeons insert SEMS by endoscopy, inserting a fibre optic camera—either through the mouth or colon—to reach an area of narrowing. As such, it is termed an endoprosthesis. SEMS can also be inserted using fluoroscopy where the surgeon uses an X-ray image to guide insertion, or as an adjunct to endoscopy. The vast majority of SEMS are used to alleviate symptoms caused by cancers of the gastrointestinal tract that obstruct the interior of the tube-like (or luminal) structures of the bowel — namely the esophagus, duodenum, common bile duct and colon. SEMS are designed to be permanent and, as a result, are often used when the cancer is at an advanced stage and cannot be removed by surgery. (en)

Possono anche essere inseriti utilizzando la fluoroscopia in cui un'immagine a raggi X viene utilizzata per guidare l'inserimento o utilizzata come tecnica aggiuntiva all'endoscopia. La stragrande maggioranza degli stent auto-espandibili sono usati per alleviare i sintomi causati da tumori del tratto gastrointestinale che ostacolano l'interno delle strutture tubolari dell'intestino, cioè l'esofago, il duodeno, il dotto biliare comune e il colon. Questi stent sono progettati per essere permanenti e, di conseguenza, sono spesso utilizzati quando il tumore è in fase avanzata e non può essere rimosso chirurgicamente. Talvolta possono essere utilizzati anche nel sistema vascolare, solitamente in aorta nel sistema vascolare periferico. (it)
