Recent advances in the use of stents for esophageal disease

The use of self-expanding metal esophageal stents has evolved dramatically over the last 20 years. Stents themselves have morphed from simple open-mesh wire devices to a variety of partially and fully covered metal and plastic protheses designed to resist in-growth and migration. Indications include grown considerably from simply palliating malignant dysphagia to the treatment of benign conditions such as refractory strictures, perforations, and fistulas, bridging tumors through neoadjuvant therapy and even serving as support for mucosal healing after ablative therapies. This article describes the current experience with esophageal stenting for malignant and benign conditions and examines new innovations in stent design and applications.
