The problem of prophylaxis of incompetence of bronchial stump and bronchial fistula is many sided. Notwithstanding the development of new technologies, perfection of surgical technique, its frequency still remains on high level that persistently 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 3 mm and with effectiveness at 83.2% patients after rightside PE and at 92.3% patients after leftside PE. In case of BPF with diameter more than 3 mm the number of satisfactory results of BFS reaches only 33.3%. but, it is necessary 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%)., F.
