The problem of prophylaxis of incompetence of bronchialstump and bronchial fistula is many sided. Notwithstandingthe development of new technologies, perfection of surgicaltechnique, its frequency still remains on high level thatpersistently requests the search of new ways for resolving this problem, which preserved its topicality till nowadays. We have found that: The most efficiency of BFS is achieved during treatment of bronchial fistulas with diameter up to 3mm and with effectiveness at 83.2% patients after right­sidePE and at 92.3% patients after left­side PE.In case of BPF with diameter more than 3 mm the numberof satisfactory results of BFS reaches only 33.3%. but, it isnecessary to mention that among patients with BPF sized over 3 mm after left­side PE the effectiveness of BFS significantly exceeds as general index (50.0% against 33.3%) so after right­side PE (50.0% against 25.0%).
