Bronchoscopic management of prolonged air leak.

Prolonged pulmonary parenchymal air leaks are an important clinical problem. Standard treatment of prolonged air leaks include continued chest tube drainage, pleural sclerosis, or surgery. Approaches that are less invasive than bedside sclerosis or surgery are desirable but bronchoscopy approaches tried over the years have had limited success. In 2001, an American College of Chest Physicians (ACCP) consensus statement concluded there was no role for bronchoscopy for the treatment of prolonged air leaks. The development of bronchial valves for treatment of emphysema allowed the use of these devices for air leaks under compassionate use regulations. Multiple reports of successful bronchial valve treatments, along with the US Food and Drug Administration's (FDA) humanitarian use approval of a bronchial valve for certain postsurgical air leaks, provide new evidence that there is likely a role for endobronchial treatment of prolonged air leaks in selected patients.
