The objective of lung volume reduction surgery (LVRS) is the safe, effective, and durable palliation of dyspnea in appropriately selected patients with moderate to severe emphysema. Appropriate patient selection and preoperative preparation are prerequisites for successful LVRS. An effective LVRS program requires participation by and communication between experts from pulmonary medicine, thoracic surgery, thoracic anesthesiology, critical care medicine, rehabilitation medicine, respiratory therapy, chest radiology, and nursing. The critical analysis of perioperative outcomes has influenced details of the conduct of the procedure and has established a bilateral, stapled approach as the standard of care for LVRS. The National Emphysema Treatment Trial (NETT) remains the world's largest multi-center, randomized trial comparing LVRS to maximal medical therapy. NETT purposely enrolled a broad spectrum of anatomic patterns of emphysema. This, along with the prospective, audited collection of extensive demographic, physiologic, radiographic, surgical and quality-of-life data, has positioned NETT as the most robust repository of evidence to guide the refinement of patient selection criteria for LVRS, to assist surgeons in providing optimal intraoperative and postoperative care, and to establish benchmarks for survival, complication rates, return to independent living, and durability of response. This article reviews the evolution of current LVRS practice with a particular emphasis on technical aspects of the operation, including the predictors and consequences of its most common complications.Keywords: emphysema; surgery; complications; outcomes Pneumectomy or the nonanatomic resection of emphysematous lung by thoracotomy to palliate chronic dyspnea was proposed and tested by Otto Brantigan in the 1950s (1). While the physiologic principles of the procedure appeared to benefit survivors, operative morbidity and mortality proved prohibitive and relegated the procedure to the obscure pages of the history of surgery for emphysema, where it lay alongside costochondrectomy, phrenic nerve lysis, and glomectomy (2). Joel Cooper and colleagues resurrected the concept of partial pneumectomy nearly four decades later, advocating a bilateral, nonanatomic, stapled resection through a median sternotomy. Forty years of advances in anesthesia, critical care, pulmonary rehabilitation, and surgical instrumentation, along with the expertise of the Washington University group, yielded a considerable reduction in operative morbidity and mortality, and lung volume reduction surgery (LVRS) was (re)born (3).The objective of LVRS is the safe, effective, and durable palliation of dyspnea in appropriately selected patients with moderate to severe emphysema. Before the National Emphysema Treatment Trial (NETT), there were several reported single institutional, case-controlled series of LVRS demonstrating encouraging results with regard to mean improvements in spirometry, 6-minute-walk distance, self-reported dyspnea, and supplemental oxygen use (...
