The insertion of intraluminal stents is an effective method of relieving the distressing symptom of @entity1763 in @entity1 with obstructive lesions in the @entity825 and main-stem bronchi. We report our experience in the use of the studded Dumon @entity1346 stent (Endoxane prosthesis; Axion, Aubagne, France). Between February 1994 and August 1996, 42 stents were placed in 30 @entity1 . Of the 27 @entity1 with a malignant stricture, 10 had @entity189 , 13 @entity189 involving the tracheobronchial tree. The benign lesions were made up of two @entity378 and one suprastomal stenosis after tracheostomy. Stents were placed through a rigid bronchoscope with @entity1 under general anesthesia. Postplacement assessment was performed with a 10-point, symptom-based visual analog scale. In eight less urgent cases, forced expiratory volume in 1 second and forced vital capacity were determined before and after surgery. The mean symptomatic improvement on the 10-point scale was 6.1 points, whereas the forced expiratory volume in 1 second (in the eight @entity1 tested) improved by 75%, and the forced vital capacity improved by 54%. The median survival was 2 months for @entity1 with @entity189 and 3 months for @entity1 with @entity189 . Two @entity1 with @entity189 and all of the @entity1 with the benign lesions were alive and well after 12 months of follow-up. Insertion of the Dumon stent is a simple, safe, and effective method of countering the distressing symptoms arising from obstructive @entity75 .
