IntroductionChronic obstructive pulmonary disease (COPD) is a debilitating disease and is projected to rank fifth worldwide in terms of burden of disease and in terms of mortality. Surgical lung volume reduction (LVRS) has been suggested to produce favorable outcomes in patients with severe emphysema. However, as clinical evidence on endoscopic lung volume reduction (ELVR) with valves (EBV) accumulates, these techniques seem promising since they might also lead to significant ameliorations of both lung function parameters and quality of life. Notwithstanding, a systematical analysis of treatment approaches is still missing and reports on treatment outcome per treatment technique are predominantly of anecdotal character. Using data from the LE-R, our main goal is to describe treatment outcomes of the applied strategies over time. MethodsThe LE-R is a national multicenter prospective open label clinical study collecting exclusively data on patients with severe emphysema treated at specialized centers all over Germany. The patients were followed up after 3 months, and the lung function (FEV1, RV, VC, DLCO) as well as the clinical status and the quality of life, measured with the 6-MWT, and mMRC were documented. Results212 cases were treated with endobronchial valves and 129 cases had a surgical procedure. The overall mean age was 65.0 y (SD 7.7) and there was a predominance of the male gender (63.6%). Table 1 depicts differences of lung function and quality of life between the groups at baseline and 3-months follow up.ConclusionsOur first results suggest that both surgical and endoscopic lung volume reduction with valves are reliable and efficacious treatment strategies in patients with severe emphysema. These findings might serve as a basis for the development of future research focusing on treatment types that should be applied to the specific patients’ subgroups.
