The management of obstructive lung disease, particularly emphysematous lung disease, is aggressively being pursued. The patient populations that will experience the greatest benefit with lung volume reduction are those that are the worst candidates for surgical intervention. Identifying a bronchoscopic approach that has a true impact on this patient population will be a major accomplishment in the management of patients with chronic obstructive pulmonary disease. This article highlights the work currently ongoing in the area of bronchoscopic lung volume reduction. There are tools now clinically available in some locations throughout the world, but no standardized technique exists.
