Bronchopleural fistulas represent a serious complication of pulmonary surgery. Surgical treatment of bronchopleural fistulas has a high morbidity and mortality rate. Endoscopic sealing procedures are less invasive and more effective. We describe two patients successfully treated for fistulas stemming from pulmonary surgery. Biological (Tissucol) and synthetic glues (N-butyl-2-cyanoacrylate: Histoacryl) have been used. The technique must be chosen according to the fistulas' characteristics: Tissucol for small and medium-size fistulas, Histoacryl for large ones.
