The Impact

<b><i>Background:</i></b> Hypermetabolism and muscle wasting frequently occur in patients with severe emphysema. Improving respiratory mechanics by bronchoscopic lung volume reduction (BLVR) might contribute to muscle maintenance by decreasing energy requirements and alleviating eating-related dyspnoea. <b><i>Objective:</i></b> The goal was to assess the impact of BLVR on energy balance regulation. <b><i>Design:</i></b> Twenty emphysematous subjects participated in a controlled clinical experiment before and 6 months after BLVR. Energy requirements were assessed: basal metabolic rate (BMR) by ventilated hood, total daily energy expenditure (TDEE) by doubly labelled water, whole body fat-free mass (FFM) by deuterium dilution, and physical activity by accelerometry. Oxygen saturation, breathing rate, and heart rate were monitored before, during, and after a standardized meal via pulse oximetry and dyspnoea was rated. <b><i>Results:</i></b> Sixteen patients completed follow-up, and among those, 10 patients exceeded the minimal clinically important difference of residual volume (RV) reduction. RV was reduced with median (range) 1,285 mL (−2,430, −540). Before BLVR, 90% of patients was FFM-depleted despite a normal BMI (24.3 ± 4.3 kg/m<sup>2</sup>). BMR was elevated by 130%. TDEE/BMR was 1.4 ± 0.2 despite a very low median (range) daily step count of 2,188 (739, 7,110). Following BLVR, the components of energy metabolism did not change significantly after intervention compared to before intervention, but BLVR treatment decreased meal-related dyspnoea (4.1 vs. 1.7, <i>p</i> = 0.019). <b><i>Conclusions:</i></b> Impaired respiratory mechanics in hyperinflated emphysematous patients did not explain hypermetabolism. <b><i>Clinical Trial Registry Number:</i></b> NCT02500004 at www.clinicaltrial.gov.

ABSTRACT Lung volume reduction surgery (LVRS) is an option for select patients with advanced chronic obstructive pulmonary disease (COPD). Current guidelines recommend LVRS for patients with appropriate physiology and heterogeneous distribution of emphysema predominately involving upper lobes. We present an unusual case of a 72-year-old male with an advanced COPD who suffered with recurrent exacerbations despite optimal medical management. He underwent a two-stage bilateral lower lobe LVRS for heterogeneous lower lobe emphysema via video-assisted thoracoscopic (VATS) approach. This resulted in a significant subjective as well as objective improvement in his pulmonary functions, 6-min walk distance and subsequent discontinuation of supplemental oxygen.
