Abstract

The aim of lung volume reduction surgery is to alleviate the symptoms of severe emphysema and to improve the life quality of the patient. The appropriate canditates (approximately 20% of all emphysematic patients examined in our clinic) had considerable dyspnea, an increased lung capacity, and a heterogenous dissemination of the emphysema with regional destruction of the parenchyma, hyperinflation and poor perfusion. After preoperative physiotherapy with a specified rehabilitation aim, a resection of 20 to 30% of the total lung volume was performed via sternotomy. From January 1993 to February 1996, 150 patients underwent bilateral lung volume reduction (age range = 36 to 77 years). The mean forced expiratory volume in 1 s (FEV1) was preoperatively 25% of the predicted value, the total lung capacity (TLC) 142% and the residual volume (RV) 283%. 94% of these patients nessecitated oxygen supply at rest or during exercise. The 90-day mortality was 4%. All patients except 1 were extubated immediately after operation. The median hospital stay was 10 days in the first 100 patients and 7 days in the last 50. An increase of the FEV1 by 51% and a decrease of the RV by 28% was observed 6 months after operation. The mean PaO2 was improved by 8 mm Hg while the percentage of oxygen dependent patients went down from 50 to 16%. In addition a raise of the perseverance capacity, a clear decrease of dyspnea and an improvement of the life quality were achieved. These results persist after 1 (n = 56) and 2 (n = 20) years after operation. Lung volume reduction leads to an improvement of the lung function, symptoms and the quality of life, which is superior to that achieved by maximal clinical intervention.
