Objectives: To determine the feasibility, safety, and efficacy of treating benign bronchial stenosis with laryngoscopy, jet ventilation, intralesional corticosteroids, and cutting-balloon bronchoplasty.
Study design: Case series with planned data collection.
Setting: National airway unit.
Subjects and methods: Ten adult patients with bronchial stenosis caused by Wegener's granulomatosis (n = 6), tuberculosis (n = 2), intubation (n = 1), and photodynamic therapy (n = 1) who underwent bronchoplasty using cutting-balloon dilation via suspension laryngoscopy in 2009. Information about patient demography, etiology, lesion characteristics, and details of the interventions were recorded. Patients underwent spirometry before surgery and at last follow-up. Chest infection rate in the 6 months before bronchoplasty and from bronchoplasty to the last follow-up was ascertained.
Results: There were 3 men and 7 women. Mean age at bronchoplasty was 46 ± 20 years. Length of stay was 1 day in all cases, and no treatment-related complications occurred. One patient required a second bronchoplasty at 55 days. Mean follow-up was 7 ± 2.3 months. Forced expiratory volume in 1 second increased from a prebronchoplasty mean of 1.6 ± 0.6 to 2.2 ± 0.5 at last follow-up (P < .0001; paired Student t test). Forced vital capacity rose from 2.7 ± 0.6 to 3.1 ± 0.6 (P = .02), and peak expiratory flow rate increased from 3.7 ± 0.8 to 5.0 ± 0.8 (P < .0001). Chest infection rate fell from an average of 0.7 ± 0.3 infections per month to 0.2 ± 0.2 (P < .003; paired Student t test).
Conclusion: Cutting-balloon bronchoplasty via suspension laryngoscopy is an effective treatment for benign bronchial stenosis. It is safer than airway stenting and is less invasive than thoracotomy. The authors propose its use as first-line treatment for this condition.
