Empyema with fistula usually resists conservative treatment such as thoracic cavity drainage and administration of antibacterial agents, thus it often requires surgeries such as fenestration, omental/muscle filling, and thoracoplasty. However, due to advanced age and poor condition, conducting invasive surgeries is often difficult in elderly patients. We report a case with the improvement of empyema by bronchial filling with endobronchial Watanabe spigot (EWS) under thoracoscopic observation for an 89-year-old patient who had developed chronic empyema with a bronchial fistulas. After filling EWS, air-leakage from bronchial fistula disappeared and the patient could discharged from the hospital successfully.
