A Novel Technique to Enhance the Effectiveness of Bronchial Occlusion for Intractable Pneumothorax: Modified Bronchial Occlusion with Silicone Spigots and Adjunctive Pleurodesis

Background: In intractable pneumothorax, air leakage often persists after bronchial occlusion due to collateral ventilation. This study aimed to evaluate the efficacy and safety of a novel technique called modified bronchial occlusion with silicone spigots (MBOS), which combines bronchial scrubbing and a thrombin patch with silicone spigot placement using a guiding device and guide sheath, for addressing this challenge.
