Conservative management of empyema-complicated post-lobectomy bronchopleural fistulas: experience of consecutive 13 cases in 9 years.

Background: Bronchopleural fistula (BPF) is an infrequent but life-threatening complication after lung surgery. Tentative closure of the fistula and irrigation have been the conventional treatments, but are also surgically challenging and associated with a considerable failure rate. This study reports on a conservative practice of this difficult issue, in aim to examine its outcomes. Method: All enrolled cases were handled consecutively from September 2006 to June 2015. The empyema was first properly drained till disseminated pneumonia controlled. After conducting lavage, tube drainage was gradually transited to postural drainage. During the follow-up, information on tube removal, fistula healing, and survival were recorded. Results: Thirteen cases were enrolled, including 9 rights and 4 lefts. The primary diseases were lung cancer [10], lung abscess [1], organizing pneumonia [1], and aspergillosis [1]. Early fistula (<= 30 days postoperatively) occurred in 8 cases and late fistula (> 30 days postoperatively) in 5 cases. Two patients underwent debridement to ascertain complete drainage. Chest tubes retained from 7 to 114 days (mean 40.54 +/- 30.49 days) before removal. At follow-up, we observed gradually narrowing-down of all residual cavities, and symptoms of fistula and empyema eventually disappeared in all patients. No complication or death occurred during the follow-up. Conclusions: Conservative management by a combination of tube and postural drainage provides an effective and safe treatment for empyema-complicated post-lobectomy BPFs.
