Lung volume reduction surgery for emphysema. A review.
Lung volume reduction surgery is emerging as a promising treatment option for selected patients with severe, debilitating end-stage emphysema refractory to medical management. Lung volume reduction surgery involves the removal of space occupying severely diseased, slowly ventilating and hyperexpanded lung, thus allowing the better conserved adjoining lung parenchyma to expand into the vacated space and function effectively. The operation can be accomplished by unilateral or bilateral thoracoscopy, thoracotomy or median sternotomy. The most emphysematous areas are excised using stapling or laser techniques or both. This review summarises the results of lung volume reduction surgery performed by various operative techniques. Results indicate that in the majority of patients improvement occurs in subjective dyspnoea and objective pulmonary function while oxygen and steroid dependence are reduced or eliminated at the cost of acceptable mortality and morbidity. Even though bilateral procedures produced much greater improvement, it is emphasized that it is the lung resection and not the operative approach that is critical to the success of the operation. Regardless of the technique used, the surgical treatment of emphysema is palliative in nature.
