Abstract
- We made a national questionnaire survey of conditions and results of lung volume reduction surgery (LVRS) performed for pulmonary emphysema in 273 hospitals. The survey covered: number of hospitals, number of patients, indications, operative procedures, improvement of FEV1% and dyspnea score, mortality, cause of death, 5-year survival rate, characteristics of patients who died, and current conditions of LVRS. The response rate was 63%. A total of 619 patients at 41 hospitals underwent LVRS. The most common types of surgical procedure were bilateral LVRS through median sternotomy and unilateral LVRS with video-assisted thoracoscopic surgery (VATS), followed by bilateral LVRS with VATS. Postoperative improvement in FEV1% averaged 39%. Dyspnea improved in 80% of patients. Mortality rate was 1.9% (8 of 432 cases). Postoperative infectious diseases, namely pneumonia and sepsis, were common causes of death. The 5-year survival was 65 +/- 8%. The causes of death over 5 years were respiratory failure in 60%, malignant neoplasms in 17%, cardiovascular accidents in 13% and others in 10%. The number of operations and hospitals decreased in 2002, compared to 2001.
