Enteral self-expandable metal stent for malignant luminal obstruction of the upper and lower gastrointestinal tract: a prospective multicentric study.

Background: Self-expanding metal stents (SEMSs) are used to treat malignant stenosis of the gastrointestinal (GI) tract, as a safe, feasible, and minimally invasive option for reestablishing luminal patency. However, the literature offers scant prospective data on the clinical outcome of these patients.

Aim: To assess the technical success, complications, and clinical outcomes of patients with a SEMS placed for malignant upper and lower GI obstruction.
