Lung function in patients operated for chronic pleural empyema

Area of Science:

• Pulmonary Medicine
• Thoracic Surgery
• Diagnostic Imaging

Background:

• Chronic pleural empyema often necessitates surgical intervention, such as decortication, to remove infected tissue and improve lung function.
• The long-term effects of decortication on various aspects of lung function are not fully understood, necessitating further investigation.

Purpose of the Study:

• To prospectively evaluate lung function following lung decortication in patients with chronic pleural empyema.
• To assess parameters including blood gases, spirometry, lung perfusion, ventilation, and alveolar permeability.

Main Methods:

• Prospective study involving 28 patients (20 men, 8 women) who underwent lung decortication.
• Post-operative assessments at 28 weeks included blood gas analysis, spirometry, lung perfusion and ventilation scans, and alveolar permeability tests.

Main Results:

• Reduced lung perfusion (median 45.2% right, 36% left) and ventilation (mean 44.4% right, 37% left) were observed.
• Ventilation-perfusion inequality affected 78.6% of patients, and 35.7% showed impaired epithelial integrity.
• Over half of patients (53.6%) had severe reductions in at least one functional parameter.

Conclusions:

• Lung decortication for chronic pleural empyema results in mild reductions in individual lung function parameters.
• However, the majority of patients experience more severe impairment due to multilevel functional lung damage.
• These findings highlight the significant and complex impact of decortication on long-term lung function.
