The recent advances in enteral stents design and composition introduced novel usage and indications, heading to a continuous addition of prostheses application in clinical practice. Since the first use to palliate malignant diseases, improving patient's quality of life, in the last decades we assisted to a large spread, often becoming a first choice treatment in GI disorders. Indeed, the clinical indication of gastrointestinal stents includes endoscopic treatment of fistula and leaks besides the well-established role of restoring lumen patency in benign and malignant conditions. Several different kind of stents have been developed, each one with its own characteristics and benefits, including self-expandable plastic and metal stents, available as uncovered, partially covered, and fully covered as well as biodegradable stents. Recently, new drug-eluting stents, working both as palliative treatment and as local chemotherapy, are under evaluation. This review aims to critically evaluate the most recently published literature about enteral stents and to address endoscopists' choice for a better patient management.
