Abstract :Objective To evaluate metallic stent implantation for the treatment of esophageal cancer postradiation stricture.Methods Metallic stents were set in 36 patients ,of them ,there were 4 esophago - mediastinal fistula , 5 esophago - tracheal fistula and 1 esophago - mediastinal - tracheal fistula , and nickel - titanium heat - memory binary alloy were used. 40 stents implantation were monitored under fluoroscopy .Results Stentimplantation was succeeded in all 36 cases , of them , two stents were set in four patient respectively. Tracheal stent was implanted in one patient with esophago - tracheal fistula before implanted esophageal stent. Dysphagia were markly improved or completely alleviated with esophago - mediastinal fistula and esophago - tracheal fistula sealed completely after the procedures.Conclusion The diameter of esophageal stent seldom exceeding 1.8cm is more safe and effective therapy for the treatment of esophageal cancer postratiation stricture.
