Abstract
: We report a 4-year experience using a new silicone Y-stent characterized by highly elastic construction material, optimal inner diameter, and nonstick surface quality. Fifty patients with advanced malignant disease involving the carina were treated by rigid bronchoscopy including dilatation using laser therapy and/or mechanical dilatation followed by Y-stent insertion using a dedicated stent applicator. Mean survival was only 109 days because of the severity of illness, but quality of life was good. Particularly good results with prolonged survival were achieved in 19 patients with esophageal cancer. For the 8 patients with esophageal carcinoma with invasion or compression of the airway without fistula, mean duration of survival was 138 days. In the 11 patients with tracheoesophageal fistulas in the vicinity of the carina, survival was only 71 days. Good life quality was directly related to good tolerance and complete reestablishment of respiratory function.
