Bronchopleural fistula(BPF) occurs as a postoperative complication in 2 to 5 percent of pulmonary resection. The detection of BPF is generally difficult and various diagnostic methods have been utilized to identify the site of the fistula in order to treat it adequately. Closure of these BPF can be surgical intervention or bronchoscopic application of various sealing agents. We report an experience with use of bronchoscopic instillation of n-butyl-2-cyanoacrylate(Histoacryl ) for closure of a postpneumonectomy BPF.
