Figure 4. Mechanism of endoscopic bronchial occlusion with an endobronchial Watanabe spigot (EWS) in pneumothorax and hemoptysis. (A) In the treatment of pneumothorax, the EWS is inserted into the bronchus responsible for the air leak to occlude that bronchus. This occlusion prevents airflow through the lung fistula and assists in closing the fistula. (B) In the treatment of airway hemorrhage, the EWS is inserted into the bleeding bronchus to stop the outflow of blood to other bronchi. In addition, the occluded bronchus fills with blood and coagulates, resulting in compression hemostasis.
