title: Lung-volume reduction surgery for end-stage chronic obstructive pulmonary disease.
abstract: Lung-volume reduction surgery (LVRS) has been proposed as a palliative treatment for selected patients with diffuse emphysema and end-stage chronic obstructive pulmonary disease who have failed conventional therapy. A number of surgical techniques have been used that are designed to reduce lung volume by surgical resection or laser plication. These techniques are designed to restore previous compromised lung elastic recoil so that expiratory airflow obstruction is reduced, respiratory mechanics are improved, and disabling dyspnea is relieved. Preliminary data derived from both published and unpublished information indicate some favorable short-term benefits. However, objective postoperative data are available for only a small proportion of patients, and long-term followup data are not available. In addition, these surgeries are associated with significant morbidity (and a 6 percent [approximate] surgical mortality) and prolonged hospital stays in a substantial percentage of patients. Patient selection criteria are heterogeneous and in flux, and controversy continues concerning the most appropriate surgical techniques for various categories of patients. The current data do not permit a logical and scientifically defensible conclusion regarding the risks and benefits of LVRS.
