BACKGROUND: Prolonged alveolar-pleural air leaks are associated with increased morbidity and mortality. Endoscopic valve therapy has been recently introduced as a potential less invasive treatment option. We aimed at quantifying the effects of valve therapy on air leak flow and clinical outcomes in patients with prolonged air leaks. METHODS: We report on a series of 16 patients with high comorbidity and evidence of continuous air leak flow in whom chest tubes remained in place for at least 7 days. After identification of the source of the air leak by use of the balloon occlusion technique, endobronchial one-way valves were implanted. Digital chest tube monitoring was used to assess air leak flow before, during, and after valve implantation until chest tube removal. RESULTS: The source of the air leak was endoscopically identified in 13 patients (81%). After valve implantation, air leak flow decreased significantly from 871±551 mL/min to 61±72 mL/min immediately after the intervention (p<0.001). The mean duration of chest tube drainage was 18±8 days before and 9±6 days after the intervention (p<0.01). Ten patients were considered responders, and 3 patients were nonresponders. Responders demonstrated consistent air leak flow levels below 100 mL/min until chest tube removal. Long-term follow-up was available for 9 patients. No adverse events related to the valve implants were reported at follow-up. Seven patients underwent valve removal without any further complications. CONCLUSIONS: Endoscopic implantation of one-way valves leads to a significant reduction in air leakage flow and may thus be a valuable treatment option in patients with prolonged air leakage.
