Abstract

Study objective To evaluate the long-term stability of improvements in exercise capacity and quality of life (QOL) after lung volume reduction surgery (LVRS). Design Case-series analysis. Setting University hospital. Patients Twenty-six patients with severe airflow obstruction (mean FEV1 of 0.67+/-0.18 L) and moderate to severe hyperinflation (mean total lung capacity of 7.30+/-1.90 L). Intervention and measurements All patients underwent bilateral LVRS via median sternotomy. Serial measurement of lung function, symptom-limited cardiopulmonary exercise tests, 6-min walk distances (6MWD), and sickness impact profile (SIP) scores were done before, and at 3, 6, 12, and 18 months after surgery. Results FEV1 (0.93+/-0.29 vs 0.68+/-0.19 L, p<0.001) increased while residual volume (3.47+/-1.2 vs 4.77+/-1.5 L, p<0.001) decreased significantly at 3 months post-LVRS compared to baseline, and these changes were maintained at 12 to 18 months follow-up. Similarly, the increase in 6MWD at 3 months post-LVRS (340+/-84 vs 251+/-114 m, p<0.001) was sustained at all follow-up times. On cardiopulmonary exercise testing, total exercise time (9.0+/-1.8 vs 6.1+/-1.9 min, p<0.001), oxygen uptake at peak exercise (VO2 peak) (14.9+/-4 vs 11.9+/-3 mL/kg/min, p<0.001), maximum oxygen pulse (7.43+/-2.37 vs 5.85+/-1.96 mL/beat, p<0.005), and maximum minute ventilation (VEmax) (30.3+/-10 vs 23.5+/-7.1 L/min, p<0.001) increased significantly at 3 months post-LVRS. On serial study following LVRS, total exercise time remained significantly greater at 6 (8.5+/-1.38 min) and 12 months (8.71+/-2.0 min) post-LVRS compared to baseline (5.81+/-1.9 min, p<0.05). VO2 peak tended to be higher at all follow-up periods (3 months, 16.1+/-4.3; 6 months, 14.5+/-2.6; 12 months, 14.1+/-3.5 mL/kg) compared to baseline (12.6+/-3.9 mL/kg, p=0.08). Similarly, maximum O2 pulse tended to be higher in all follow-up studies (3 months, 8.45+/-2.7; 6 months, 7.6+/-1.7; 12 months, 7.42+/-2.1 mL/beat) compared to baseline (6.39+/-2.5 mL/beat, p=0.06). Higher VEmax continued to be observed at 6 (30+/-10 L/min) and 12 months (28+/-10 L/min) post-LVRS, compared to baseline (23+/-7 L/min, p=0.02). VEmax post-LVRS was significantly higher at 3 and 6 months compared to baseline on post-hoc analysis (p<0.05). Overall SIP scores were lower at 3 months (7 vs 18, p<0.0002) post-LVRS and were sustained in long-term follow-up. Conclusion We conclude that bilateral LVRS via median sternotomy in selected patients with severe, diffuse emphysema improves exercise performance and QOL at 3 months following LVRS and these improvements are maintained for at least 12 to 18 months in follow-up.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
