Abstract

Recently, various self-expandable metal stents (SEMS) have been developed for palliation of malignant obstruction of gastrointestinal tract. Although they have not been approved for use in benign disease, there are specific clinical indications for which expandable metal stents may be beneficial. This article reviews the use of self-expandable metal stents for malignant gastrointestinal obstruction and the use of SEMS specially developed for unusual stenting such as antimigration and antireflux mechanism.
