[Endoscopic lung volume reduction for emphysema]

Abstract

Lung hyperinflation which is a hallmark of advanced emphysema plays a major role in the exertional dyspnoea experienced by patients. This has led to the development of surgical lung volume reduction which, though effective, is also associated with significant morbidity and mortality. The goal of endoscopic lung volume reduction which has developed over several years is to decrease hyperinflation without exposing patients to the risks of surgery. Several endoscopic techniques have been assessed by high quality controlled studies: airway by-pass, instillation of glue, insertion of coils or unidirectional valves, vapour ablation. The aim of this review is to present the results of these studies in terms of functional benefit and side effects. Based on these studies, an algorithm for the endoscopic management of advanced forms of emphysema is proposed.
