Improved quality of life after lung volume reduction surgery.
Lung volume reduction surgery (LVRS) improves dyspnoea, pulmonary function, and physical performance in patients with severe pulmonary emphysema. This study investigated the impact of LVRS on health-related quality of life (HRQL) over a 2-yr period following surgery. Thirty-nine consecutive patients were prospectively assessed before LVRS, and followed over 24 months postoperatively. The assessments included pulmonary function, dyspnoea (Medical Research Council (MRC) dyspnoea score), 6-min walking distance (6MWD) and HRQL using the Short Form 36-item questionnaire (SF-36). Several domains of SF-36 improved considerably over 2 yrs after surgery: Physical Functioning: 39 +/- 4 (mean +/- SEM) versus 16 +/- 2 (p<0.01); Vitality: 51 +/- 3 versus 32 +/- 3 (p<0.01); Social Functioning: 72 +/- 4 versus 51 +/- 5 (p<0.01). Also, improvements in pulmonary function (forced expiratory volume in one second (FEV1): 27 +/- 1% predicted, residual volume (RV)/total lung capacity (TLC): 0.65 +/- 0.01), 6 MWD (274 +/- 16 m) and dyspnoea (MRC: 3.9 +/- 01) were sustained for up to 2 yrs after LVRS (FEV1 36 +/- 2% pred, RV/TLC: 0.58 +/- 0.02; 6 MWD: 342 +/- 19 m; MRC: 2.0 +/- 0.2; p<0.05). In patients with severe emphysema, lung volume reduction surgery had positive effects on health-related quality of life and pulmonary function over 2 yrs.
