Abstract

Background: Endobronchial stents are used to treat symptomatic patients with benign or malignant airway obstructions. Objectives: To evaluate the safety and outcome of airway stent insertion for the treatment of malignant tracheobronchial narrowing. Methods: The files of all patients with malignant disease who underwent airway stent insertion in our outpatient clinic from June 1995 to August 2004 were reviewed for background data, type of disease, symptoms, treatment, complications and outcome. Results: Airway stents were used in 34 patients, including 2 who required 2 stents at different locations, and one who required 2 adjacent stents (total, 37 stents). Ages ranged from 36 to 85 years (median 68). Primary lung cancer was noted in 35% of the patients and metastatic disease in 65%. Presenting signs and symptoms included dyspnea (82%), cough (11.7%), hemoptysis (9%), pneumonia (5.9%), and atelectasis (3%). The lesions were located in the left mainstem bronchus (31%), trachea (26%), right mainstem bronchus (26%), subglottis (14.3%), and bronchus intermedius (2.9%). Conscious sedation alone was utilized in 73% of the patients, allowing for early discharge. Eighteen patients (50%) received brachytherapy to the area of obstruction. Complications included stent migration (one patient) and severe or minimal bleeding (one patient each). Ninety-four percent of the patients reported significant relief of their dyspnea. Three of the four patients who had been mechanically ventilated before the procedure were weaned after stent insertion. Median survival from the time of stent placement was 6 months (range 0.25-105 months). Conclusion: Stent placement can be safely performed in an outpatient setting with conscious sedation. It significantly relieves the patient's symptoms and may prolong survival.
