title: Malignant esophageal stricture and fistula: palliative treatment with polyurethane-covered Gianturco stent.
abstract: OBJECTIVE
  To evaluate the effectiveness of a polyurethane-covered Gianturco stent in the palliative treatment of malignant esophageal stricture and fistula.
  
  
  METHODS
  Twenty-seven patients with recurrent stricture (n = 24), fistula formation (n = 8), or both (n = 5) underwent palliative treatment for aphagia (n = 15) or dysphagia (n = 12). Eight patients had fistulas to the respiratory tract or mediastinum. A 15-F delivery sheath system was passed through the stricture; the inner dilator was removed, and the stent was compressed into the sheath and advanced with a pusher catheter. Follow-up included chest radiography for 3 days and monthly esophagography or endoscopy.
  
  
  RESULTS
  Covered stents occluded fistulas and opened strictures in 100% of patients. Food intake was upgraded to liquids in 7% of patients, to soft foods in 37% and to regular foods in 56%. New stricture or fistula occurred in 4% and 7% of patients, respectively. Stent migration occurred in 15% of patients. Twenty-one patients died after stent placement, and average life expectancy was 11 weeks.
  
  
  CONCLUSIONS
  A polyurethane-covered Gianturco stent is effective in the palliation of advanced malignant esophageal strictures and fistulas.
