Esophageal stents may be self-expandable metallic stents, or made of plastic, or silicone, and may be used in the treatment of esophageal cancer. A 2007 study showed no difference in the quality of palliation between plastic and metal stents, but a novel polyester mesh stent caused more complications, especially migration.[1] {{As of|2009}}, covered self-expanding metal stents were the only FDA-approved to be placed permanently. Occasionally, these stents may be placed as part of a clinical trial or as off-label use to repair esophageal leaks or fistulae. They are placed using the guidance of fluoroscopy (x-ray) and endoscopy. Usually, they are left in for less than four weeks.{{citation needed|date=February 2009}}Additional images{{clear}}References1. ^{{cite journal |vauthors=Conio M, Repici A, Battaglia G, etal |title=A randomized prospective comparison of self-expandable plastic stents and partially covered self-expandable metal stents in the palliation of malignant esophageal Dysphagia |journal=Am.
