Effect of decortication and pleurectomy in chronic empyema patients

Abstract

Background

Fibrosis that occurs in the chronic phase of pleural empyema restricts lung movement and impairs pulmonary function. It also leads to asymmetry of the chest wall. We evaluated the efficacy of decortication and pleurectomy in improving these adverse consequences.

Methods

Data of 50 patients (42 males, mean age 49.1 ± 19.46 years) with chronic empyema who underwent lung decortication via a posterolateral thoracotomy between 2004 and 2014 were reviewed in this study. All patients had pulmonary function tests before and after surgery. Computed tomography was used to determine transverse and anteroposterior diameters of the chest before and after surgery.

Results

The patients were followed up for 11.5 ± 4.5 months. Mean forced expiratory volume in 1 s was 62.5% ± 13.61% before surgery vs. 77.3% ± 13.31% after surgery (p < 0.001). Mean forced vital capacity was 60.6% ± 14.38% before surgery vs. 78.5% ± 12.64% after surgery (p < 0.001). The improvement in patients with reduced chest wall diameters was significant (p < 0.001). Improvements in pulmonary function tests and chest wall diameters were not significantly different between patients with tuberculosis (n = 10) and those with other diseases (n = 40; p < 0.05).

Conclusion

Decortication and pleurectomy via a posterolateral thoracotomy significantly improves pulmonary function and chest wall diameters in patients with chronic empyema due to tuberculosis or other diseases.
