A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was whether bronchoscopic or other minimal access approaches to the closure of bronchopleural fistulae (BPFs) were effective compared to a conventional re-thoracotomy. Our search identified 1052 abstracts, from which we identified six case series of greater than two post-pneumonectomy bronchopleural fistula patients. These series included reports of bronchial stenting, glue occlusion and scar obliteration of fistulae. No thoracoscopic techniques were reported except in case report form. The author, journal, date and country of publication, patient group studied, study type, relevant outcomes, results, and study weaknesses of these papers are tabulated. We identified 85 post-pneumonectomy bronchopleural fistulae reported in the literature who underwent bronchoscopic procedures to attempt repair. There was a 30% cure rate using a range of bronchoscopic techniques in these series. Bronchoscopic techniques included cyanoacrylate or fibrin glue application, YAG laser therapy, injection of the vein sclerosant polidocanol and tracheo-bronchial stenting. The mortality was 40% in these patients reflecting the very high mortality with this complication. Many patients required multiple bronchoscopic procedures and also further drainage procedures of their empyemas. Bronchoscopic treatment has so far only been reported in small case series but may offer further treatment options in patients too unwell to undergo re-thoracotomy.
