It is estimated that in the United States alone there are approximately 2 million adults who have emphysema , and in the year 2000 a total of 16,700 people died from this condition , making this condition, together with other chronic lower respiratory illnesses, one of the top 15 causes of death in that year. Approximately $2.5 billion annually are spent on the treatment of emphysema and its related complications .

Originally developed in the 1950s, the procedure was abandoned because of excessive rates of complications—primarily air leaks—in patients undergoing the procedure. Advances in surgical techniques led to a resurgence of LVRS in the 1990s; however, methodological limitations of early evaluations of this procedure created uncertainties about its efficacy and concerns about the implications of rapid diffusion of an unproven technology . Although rarely stated explicitly in the early years of its development, economics has always been an important factor influencing the evaluation of LVRS. The high cost of the operation and perioperative follow-up care coupled with the large prevalence of individu...

Costochondrectomy and thoracoplasty were performed in an attempt to alter the configuration of the chest cavity, and phrenic nerve ablation or induced pneumoperitoneum were attempted to restore the curvature of the diaphragm. Numerous efforts were made to treat the airway component of chronic obstructive pulmonary disease using airway de-enervation procedures or prosthetic devices to support the membranous trachea. Improvement of pulmonary blood flow was the intent of pleurodesis. Each of these procedures enjoyed a period of popularity, but each was ultimately found to be ill-advised, resulting in severe, life-threatening complicatio...

Although some centers performing LVRS had good results and acceptable morbidity in 1994 to 1995 , the high rates of morbidity and mortality at other centers led Medicare to stop coverage for the procedure. The results of the National Emphysema Treatment Trial (NETT) show that the procedure can be performed with acceptable morbidity and mortality.

The technique was difficult and was associated with high postoperative morbidity and mortality rates. Using a modified technique based on the same principles, Cooper demonstrated significantly improved results . Since then, it has become apparent that the outcome of lung volume reduction surgery (LVRS) is dependent upon careful patient selection and surgical technique. While a discussion of patient selection criteria is beyond the scope of this article, several aspects of surgical technique are relevant, including preoperative patient preparation, surgical approach, technique of lung resection, and technical postoperative management issues.

The incidence in the United States is estimated to be at least 10 million patient-reported cases, although surveys have suggested that up to 24 million individuals might have impaired lung function . At least two million individuals are estimated to suffer from predominantly emphysema . The economic burden of these disorders is huge and increases with more severe disease . Furthermore, a marked impairment of quality of life is noted in these patients as the disease progresses . Over the past 50 years many advances have been made in the management of COPD. Despite these advances many patients continue...

In 1985 only 13 lung transplants were reported worldwide by the International Society of Heart and Lung Transplantation (ISHLT). This number rose to more than 1500 by 2001. More than 8000 lung transplants were performed worldwide between 1995 and 2001, and emphysema was the indication for transplantation in the majority of these procedures . Between 1990 and 2001 the percentage of patients transplanted for emphysema, including chronic obstructive pulmonary disease (COPD) and α-1-antitrypsin deficiency, rose from 21% to 42%, whereas transplantation performed for other pulmonary diseases fell or remained stable .

This effort is in part energized by the recognition that approximately 24 million adults in the United States have evidence of impaired lung function and experience 9.5 million office and emergency room visits, 726,000 hospitalizations, and 119,000 deaths each year . While the death rate finally appears to be stabilizing in the United States at this unacceptable rate, the problem is still escalating worldwide . Factors that impair more rapid progress in COPD treatment include misconceptions that the disease is irreversible and untreatable, lack of consensus on optimal functional outcome parameters, and incomplete understanding of appropriate short-term surrogate ...

The airflow limitation is usually progressive and associated with an abnormal inflammatory response of the lungs to noxious particles or gases . According to this concept, the chronic airflow obstruction characteristic of this condition is a mixture of small airway disease (obstructive bronchiolitis) and parenchymal destruction (emphysema), and the relative contributions of each of these factors vary from patient to patient according to his/her individual response. This chronic inflammation causes remodeling and obstruction of small airways and destruction of lun...

The rejuvenation and promulgation of lung volume reduction surgery (LVRS) in the mid-1990s provided a potential surgical treatment and new promise for selected emphysema patients. Early widespread application of LVRS and the glowing publications reporting overwhelmingly positive results brought this issue to the attention of the entire thoracic surgery community. Debates occurred at both medical and surgical meetings regarding patient selection, surgical techniques, and the true value of the procedure. However, it was in the regulatory, judicial, and legislative arenas where the most strident controversy occurred. A Medicare review of claims revealed significantly higher morbidity and mortality following LVRS tha...
