Purpose: Bronchopleural fistula (BPF) is a lethal complication, even in the modern era. Therefore, we investigated the details of patients with BPF to select an appropriate surgical strategy.
Methods: This retrospective study included 4794 consecutive patients who underwent anatomical pulmonary resection between 2008 and 2022. We evaluated the predictors of BPF using a multivariable analysis and investigated the mortality and clinical course after BPF in detail.
Results: BPF was observed in 32 patients (0.67%). In the multivariable analysis, the predictors for BPF were male sex (odds ratio [OR], 6.91), the body mass index (OR, 2.40), the vital capacity (%VC) (OR, 2.93), surgery performed (right lower lobectomy [OR, 10.92], right middle and lower lobectomy [OR, 6.97], and right pneumonectomy [OR, 16.68]), and additional resection of surrounding organs (OR, 3.47). Among the risk factors, surgery performed and male sex were very strong risk factors, with the frequency itself very low in females (0.1%). The 90-day mortality was 15.6%, and the 5-year overall survival in patients with BPF was 28.1%.
Conclusion: Our study revealed that independent risk factors and consideration of the surgical methods and sex might help determine whether or not special attention should be given to the bronchial stump, which will be of great help in surgical strategies.
