Abstract
OBJECTIVE: Recent surgical literature has highlighted the dangers of pneumonectomy for inflammatory lung disease; therefore the assessment of the risk/benefit ratio of our departmental policy. METHODS: Patients undergoing pneumonectomy for inflammatory lung disease during two 2-year periods, 1991-1992 and 1996-1997 inclusive, were retrospectively analyzed. Clinical indications for investigation and surgery, and radiographic findings were determined. Some comparisons between the two periods were drawn. Rates of morbidity and mortality were the principle outcome measures. RESULTS: One hundred and fifty-five patients, 116 males, 39 females, with an average age of 30.2 years ranging from 1-68 years, underwent pneumonectomy for ongoing features of productive cough, haemoptysis (two emergencies) and chronic empyema all with either bronchographic or computed tomography (CT) evidence of destroyed lung. One hundred and fourteen (72%) had or had had tuberculosis at time of surgery. Histology showed bronchiectasis in 53 (34%), end-stage disease in 49 (31.6%) and active tuberculosis in 48 (30.9%). Over 90% of the patients were free of disease at discharge. Mortality was two (1.2%). Morbidity (23%) included post-pneumonectomy empyema 23 (14.8%), bleeding three (1.9%), broncho-pleural fistula three (1.9%), with wound sepsis in one (0.6%) and thoracic duct injury in one (0.6%). Three groups were identified, (1) pneumonectomy through empyema - a risk group, (2) pneumonectomy in active tuberculosis and (3) pneumonectomy in children. Twenty-three post-pneumonectomy empyemas (PPE) occurred with 21 of these following pneumonectomies through empyema (PTE), six PPEs followed 27 PTEs for active tuberculosis. Fourteen of the 21 empyemas following pneumonectomy through empyema were initially sterilized. Finally 15/23 (65%) of all PPEs were sterilized. Pneumonectomy in active tuberculosis did not carry the mortality or morbidity experienced by others. Pneumonectomy in children was remarkably uncomplicated, with one PPE occurring. CONCLUSIONS: This ongoing study shows pneumonectomy for inflammatory lung to be safe, with good results. Tuberculosis, being so common, adequate pre-operative and operative cover with anti-tuberculosis drugs may enhance results.
