Lung volume reduction surgery (LVRS) is the definitive treatment for patients with severe emphysema. There is still a need for long-term data concerning the outcomes of this procedure. This study presents long-term longitudinal data on LVRS including correlation of quality of life (QOL) with pulmonary function testing metrics and includes additional analysis of patients with heterogeneous and homogeneous emphysema. Retrospective analysis of data collected from patients undergoing LVRS over a 9-year period at a single center was performed (N = 93). Pulmonary function and 6-minute walk tests as well as QOL questionnaires were administered before and 1 year after surgery. Descriptive statistics were reported for clinical outcomes and QOL indices. Wilcoxon signed-rank tests were used to examine changes from baseline to end of 1-year follow-up. Spearman correlation coefficients were used to evaluate relationships between clinical and QOL outcomes. At 1-year post surgery, mean forced vital capacity (46%, P ≤ .0001), forced expiratory volume (43%, P ≤ .0001), diffusing capacity of the lungs for carbon monoxide (16%, P ≤ .0001), and 6-minute walk distance (20%, P ≤ .0001) were increased from baseline, while residual volume decreased (23%, P ≤ .0001). There was a positive correlation between changes in QOL and forced expiratory volume, forced vital capacity, and, 6-minute walk distance. Patients having heterogeneous disease had greater improvements in forced expiratory volume, forced vital capacity, residual volume, and diffusing capacity of the lungs for carbon monoxide, and greater QOL compared with patients with homogeneous disease. LVRS continues to be a valuable treatment option for patients with advanced emphysema with reproducible improvements in clinical and QOL metrics. Careful patient selection and optimization prior to surgery are crucial to successful outcomes.
