A few cases of empyema secondary to coronavirus disease 2019 (COVID‐19) pneumonia have been reported. Here, we report our experience of a successful endobronchial occlusion using endobronchial Watanabe spigots (EWSs) for empyema with broncho‐pleural fistula secondary to COVID‐19 pneumonia. A 62‐year‐old man was diagnosed with COVID‐19 and progressed to empyema with broncho‐pleural fistula. Computed tomography (CT) imaging showed cyst formation and the right B(5)b was presumed to be a branch dependent on the cyst. The effusion and air in the pleural cavity were well drained, although the air leak persisted. Endobronchial occlusion was performed for right B(5)a and B(5)b using 7‐ and 5‐mm EWSs (Novatech, France), respectively, and the air leak ceased. This is the first report of successful treatment of empyema with bronchial fistula with endobronchial occlusion. Air leak secondary to COVID‐19 pneumonia with a limited number of air cysts may be a good indication for endobronchial occlusion.
