Summary
Bronchopleural fistula (BPF) after pneumonectomy is linked to bronchial stump diameter. Larger diameters increase risk, especially in men and on the right side. Prophylactic stump coverage is advised for diameters over 25 mm.
Area of Science:
- Thoracic surgery
- Pulmonary medicine
- Surgical pathology
Background:
- Bronchopleural fistula (BPF) is a serious complication following pneumonectomy.
- Understanding risk factors is crucial for prevention and improved patient outcomes.
Purpose of the Study:
- To analyze side- and sex-related differences in the occurrence of bronchopleural fistula (BPF) after right-sided pneumonectomy.
- To identify independent risk factors for BPF development.
Main Methods:
- Retrospective review of 209 pneumonectomy surgical pathology reports (15 with BPF).
- Analysis included patient sex, age, tumor side, TNM stage, resection margin diameter, and tumor-resection margin distance.
- Statistical analysis employed t-tests, Mann-Whitney U-tests, chi-squared tests, and logistic regression.
Main Results:
- Women were younger with smaller resection margins and fewer central tumors compared to men.
- Right-sided pneumonectomies showed shorter distances and longer resection margins.
- Multivariate analysis identified resection margin length as an independent risk factor for BPF (OR 1.177, p=0.024).
- Bronchial stump diameter was significantly influenced by gender and side (p=0.00).
Conclusions:
- Bronchial stump diameter is a major risk factor for post-pneumonectomy BPF.
- This factor explains the higher incidence in males and after right-sided pneumonectomy.
- Prophylactic stump coverage is recommended for bronchial stump diameters exceeding 25 mm.
