AbstractBronchopleural fistula (BPF) after pneumonectomy for NSCLC remains a highly morbid complication. We examined possible factors including the surgical techniques associated with BPF development. From 221 pneumonectomies for NSCLC, bronchial stump closure was mechanically performed in 192 patients and manually in the remaining 29. In all right-sided pneumonectomies mechanical closure was performed with associated stump coverage. In 114/130 left-sided procedures where mechanical closure was selected, bronchial stump remained uncovered. In the remaining 16 left-sided cases where manual stump closure was selectively performed, the stump was covered utilizing various tissues. Risk factors were classified into preoperative, intra-operative and postoperative. Five patients (2.3%) developed BPF. Univariate analysis revealed peri-operative transfusion, respiratory infection at the time of presentation, neoadjuvant therapy, right-sided pneumonectomy, manual type of bronchial closure, days of postoperative hospitalization and mechanical ventilation as significant risk factors for BPF development. Multivariate analysis followed revealing preoperative respiratory infection and right pneumonectomy as the only independent risk factors. In our series, a selected stump coverage policy showed a low incidence of BPF development. Mechanical stapling was superior to manual closure, although not as an independent factor. Early recognition of possible risk factors associated with fistula development is of paramount importance.
