Endoscopic lung volume reduction has emerged over the past several years as a promising technique to improve the respiratory functional status of patients with advanced emphysema. Nevertheless, the procedure may be associated with various complications; among them, the development of bronchiectasis related to the coils has not yet been described. We report the case of a patient with emphysema who developed localized bronchiectasis at the site of coil insertion several months after lung volume reduction coil treatment.

Meta Analysis
Reduced COPD exacerbation risk correlates with improved FEV1: A meta-regression analysis.
The mechanism by which various classes of medication reduce COPD exacerbation risk remains unknown. We hypothesized a correlation between reduced exacerbation risk and improvement in airway patency as measured according to FEV1. ⋯ A significant correlation between increased FEV1 and lower COPD exacerbation risk suggests that airway patency is an important mechanism responsible for this effect.
