Occlusion of a broncho-cutaneous fistula with endobronchial one-way valves.

Bronchopleural and broncho-cutaneous fistulas can be problematic after lobectomy for tumors or aspergillomas. Closure of the air leak and treatment of infection are essential to allow the fistula to heal. The initial treatment can usually proceed along standard lines, but if the fistula persists, then treatment can be problematic.
