OBJECTIVE: The aim of this study was to evaluate the clinical effectiveness of endoscopic bronchial occlusion (EBO) with endobronchial Watanabe spigots (EWSs), a type of silicone bronchial blocker, for managing prolonged pulmonary air leaks. PATIENTS AND METHODS: Between October 2002 and April 2010, 24 patients with surgically incurable pulmonary air leaks underwent EBO with EWSs. The spigot was grasped with forceps and inserted into the affected bronchus by using a flexible bronchoscope through an endotracheal or a tracheostomy tube. RESULTS: In each patient, at least one EWS (mean=2.8) was placed for air leaks due to pneumothorax (n=15), empyema (n=8), or postsurgical complications (n=1). Twelve patients (50%) had complete resolution of the air leaks and seven (29.2%) had a reduction in air leaks, but five (20.8%) showed no improvement. Twenty-three patients required thoracic drainage tubes, which were successfully removed after EBO in 15 patients (65.2%). Of the 24 patients, four experienced severe respiratory failure requiring mechanical ventilation but were successfully treated. Complications were spigot migration, atelectasis, pneumonia, and lung abscess, but none caused significant mortality. CONCLUSION: EBO with EWSs seems to be a reasonable and manageable treatment option for patients with prolonged pulmonary air leaks, including those with severe respiratory failure requiring mechanical ventilation.
