Efficacy and long-term clinical outcome of bronchial occlusion with endobronchial Watanabe spigots for persistent air leaks

We showed that bronchial occlusion with EWSs was effective in stopping or reducing air leaks and that 86% of our patients finally achieved complete resolution, some when the occlusion was combined with chemical pleurodesis. The rate of complications was acceptable, even after long-term placement.
