This study intends to review the literature on the efficacy, safety and feasibility of lung volume reduction surgery (LVRS) in patients with advanced emphysema. Studies on LVRS from January 1995 to December 2009 were included by using Pubmed (MEDLINE) and Cochrane Library literature in English. Search words such as lung volume reduction surgery or lung reduction surgery, pneumoplasty or reduction pneumoplasty, COPD or chronic obstructive pulmonary disease and surgery, were used. We also compared medical therapy and surgical technique. Studies consisting of randomized controlled trials, controlled clinical trials (randomized and nonrandomized), reviews and case series were analyzed. Questions regarding validity of the early clinical reports, incomplete follow-up bias, selection criteria and survival, confounded the interpretation of clinical data on LVRS. Patients with upper, lower and diffuse distribution of emphysema were included; we also analyzed as key points perioperative morbidity and mortality and lung function measurement as FEV1. Bullous emphysema was excluded from this review. Surgical approach included median sternotomy, unilateral or bilateral thoracotomy, and videothoracoscopy with stapled or laser ablation. Results of prospective randomized trials between medical management and LVRS are essential before final assessment can be established.
