Due to the esophagus distensible characteristics，patients may not recognize any symptoms until 50％ of the lumenaldiameteris compromised explaining late presentation and poor prognosis. Esophageal stents are devices used to maintain or restore the lumen of the esophagus.it is recommended that stents be placed in patients who have dysphasia caused by esophageal or gastric cardiacancer and a calculated life expectancy of 3 months or less.All metallic stents used in the esophagus are self-expanding.No balloon-expandable end prostheses rededicated for use in the esophagus.
