AbstractThe insertion of intraluminal stents is an effective method of relieving the distressing symptom of asphyxia in patients with obstructive lesions in the trachea and main-stem bronchi. We report our experience in the use of the studded Dumon silicone stent (Endoxane prosthesis; Axion, Aubagne, France). Between February 1994 and August 1996, 42 stents were placed in 30 patients. Of the 27 patients with a malignant stricture, 10 had carcinoma of the bronchus, 13 carcinoma of the esophagus, and 4 metastatic carcinoma involving the tracheobronchial tree. The benign lesions were made up of two tuberculous strictures and one suprastomal stenosis after tracheostomy. Stents were placed through a rigid bronchoscope with patients 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 patients tested) improved by 75%, and the forced vital capacity improved by 54%. The median survival was 2 months for patients with;carcinoma of the bronchus and 3 months for patients with carcinoma of the esophagus. Two patients with metastatic carcinoma and all of the patients 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 tracheobronchial lesions.
