Expert statement: pneumothorax associated with endoscopic valve therapy for emphysema--potential mechanisms, treatment algorithm, and case examples.

Abstract

The use of endoscopically placed unidirectional valves for the treatment of emphysema is increasing. With better patient selection, there is also an increased likelihood of complications associated with the procedure, such as postprocedural pneumothorax. There is, however, little evidence of pneumothorax management in patients with severe COPD and emphysema. This report describes an expert recommendation that has been developed to outline pneumothorax management after valve placement to inform physicians and patients of the risk-benefit profile and to assist them in decision making. Skilled and aggressive pneumothorax management is necessary in this patient population, and by following these recommendations traumatic scenarios, prolonged drainage, extended hospitalizations, and/or surgery might be avoided in many cases.
