Feasibility and safety of self-expandable metal stent in nonmalignant disease of the lower gastrointestinal tract

Ludovica Venezia et al. World J Gastrointest Endosc. .

Abstract

In recent years, self-expandable metal stents (SEMSs) have been employed to treat benign gastrointestinal strictures secondary to several conditions: Acute diverticulitis, radiation colitis, inflammatory bowel disease (IBD), and postanastomotic leakages and stenosis. Other applications include endometriosis and fistulas of the lower gastrointestinal tract. Although it may be technically feasible to proceed to stenting in the aforementioned benign diseases of the lower gastrointestinal tract, the outcome has been reported to be poor. In fact, in some settings (such as complicated diverticulitis and postsurgical anastomotic strictures), stenting seems to have a limited evidence-based benefit as a bridge to surgery, while in other settings (such as endometriosis, IBD, radiation colitis, etc.), even society guidelines are not able to guide the endoscopist through decisional algorithms for SEMS placement. The aim of this narrative paper is to review the scientific evidence regarding the use of SEMSs in nonmalignant diseases of the lower gastrointestinal tract, both in adult and pediatric settings.

Keywords: Benign strictures; Lower gastrointestinal tract; Self-expandable metal stents.
