Background: Bronchopleural fistula is a potentially fatal complication of pulmonary resections, especially pneumonectomy.
Methods: Univariate and multivariate analyses of the development of bronchopleural fistula were performed in 12 patients with bronchopleural fistula and 102 patients without bronchopleural fistula who had undergone pneumonectomy from January 1983 through December 2005.
Results: Bronchopleural fistula developed after pneumonectomy in 12 patients (8.5%). Seven (58.7%) of the 12 patients died of bronchopleural fistula. Univariate analysis showed that preoperative infection, right pneumonectomy, and pathological N2, 3 disease significantly contributed to the development of postpneumonectomy bronchopleural fistula (p=0.0002, p=0.0043, and p=0.0387, respectively). Multivariate analysis also showed that preoperative infection, right pneumonectomy, and pathological N2, 3 disease were significant risk factors for postpneumonectomy bronchopleural fistula.
Conclusions: Bronchopleural fistula is strongly associated with preoperative infection, right pneumonectomy, and pathological N2, 3 disease. Bronchial stump coverage with pedicled tissue flaps and preservation of the bronchial arteries during mediastinal lymph node dissection are recommended to maintain the blood supply to the bronchial stump in patients at risk.

Bronchopleural Fistula (BPF) represents one of the gravest complications post-lobectomy. Present treatment strategies encompass a wide array of surgical techniques complemented by essential adjunct therapies. Despite numerous treatment modalities, mortality rates associated with BPF remain disconcertingly high.

Objective: To investigate which fluoroquinolone is safer when combined with bedaquiline for tuberculosis treatment by using the FDA Adverse Event Reporting System (FAERS) database.
Methods: We selected data from the first quarter (Q1) of 2013 to the second quarter (Q4) of 2024 from the FDA FAERS database for disproportionality analysis. Signal detection was conducted using the Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Bayesian Confidence Propagation Neural Network (BCPNN), and Empirical Bayesian Geometric Mean (EBGM).

Open-window thoracostomy is an effective treatment for refractory postpneumonectomy empyema. However, it can leave large thoracic dead space, and bronchopleural fistulas (BPF) are a common major complication. These problems can be treated with myocutaneous flap transfer or negative-pressure wound therapy (NPWT).
