Esophageal stent

Chest radiograph showing a stent in the distal esophagus

An esophageal stent is a stent (tube) placed in the esophagus to keep a blocked area open so the patient can swallow soft food and liquids. 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^[update], 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]}

OBJECTIVES: Improved outcomes of thoracic endovascular aortic repair (TEVAR) compared with open repair have changed the therapeutic paradigm of thoracic aortic lesions. As the number of TEVAR survivors has grown, reports of complications have similarly increased. Although secondary endovascular resc
