Tracheobronchial Obstruction from Esophageal Carcinoma: Bronchoscopic Treatment with Neodymium:Yttrium-Aluminum-Garnet Laser

Abstract

Tracheobronchial obstruction resulting from esophageal carcinoma is uncommon. Patients with advanced esophageal carcinoma with tracheobronchial obstruction usually present with severe dyspnea or hemoptysis or both and may die of suffocation. The Lahey Clinic experience using laser bronchoscopy for the palliation of symptoms of airway obstruction in patients with esophageal carcinoma is presented. From 1982 to 1990, nine patients were treated in 13 procedures using the neodymium:yttrium-aluminum-garnet laser. Of the patients, seven had undergone previous treatment of the primary tumor. Tumors were located in the trachea in seven patients and in the main stem bronchi in three patients. Improvement of the airway caliber was achieved in all patients with relief of the dyspnea. The mean hospital stay was 2 days. One patient lived 4 years after laser treatment with no recurrence of tumor, and one patient died 1 week after treatment as a result of his poor general condition. The rest of the patients lived 3 to 41 weeks, with a median survival of 35 weeks. No complications were related to the procedures, and in particular, no tracheoesophageal fistulas developed. Our experience indicates that bronchoscopic application of this laser in conjunction with other treatment modalities can improve the quality and duration of life in selected patients with esophageal carcinoma that invades and obstructs the trachea.
