Chronic obstructive pulmonary disease (COPD) is the fourth leading cause of death in the United States, as well as a major cause of disability. In its end stages, its inexorable progression results in profound suffering for those afflicted. Medical therapy has proven largely ineffective in improving dyspnea and functional status, and does not alter pulmonary function. Over the past decade, lung-volume reduction surgery (LVRS) has been proposed as a palliative treatment for certain subgroups of COPD patients with emphysema, but initial enthusiasm over its application had been confounded by uncertainty about the potential cost and morbidities associated with LVRS, as well as durability of its beneficial effects. Longer-term follow-up data of initial uncontrolled trials along with several landmark controlled trials have recently been published, offering insight as to the "proper" place of LVRS in the treatment of these unfortunate patients. This review will summarize and offer perspective on these recent findings, as well as offer thoughts on recent refinements in preoperative imaging assessment, and pioneering efforts in less invasive bronchoscopic lung-volume reduction that should further aid the clinician in defining who should benefit from this treatment approach. ⋯ Lung-volume reduction surgery can improve both objective and subjective measures of lung performance in properly selected COPD patients. Durable effects of up to 5 years have now been demonstrated. As costs (both fiscal and emotional) of such an approach are high, refinement in patient selection remains a current goal in the surgical approach to COPD.

Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality throughout the world. This major public health threat is ranked twelfth as a worldwide burden of disease and is projected to rank fifth by the year 2020 as a cause of lost quantity and quality of life. The impact of this disease in women is significantly understudied but the evidence that does exist reveals potentially substantial gender differences in the susceptibility to, severity of, and response to management of COPD. ⋯ Chronic obstructive pulmonary disease in women is an understudied subject but is gaining attention as a significant public health threat. In developed countries, efforts at preventing the initiation of tobacco smoking and targeting smoking cessation programs in women are needed. In developing countries, efforts to promote cleaner fuels, improved stoves, better home ventilation, reduce toxic dust and fume exposures, combat infectious diseases such as TB and HIV, and improve nutrition are all ways in which the lung health of women can be improved.
