The loss of substantial portion of critically ill patient's tidal volume through a bronchopleual pleural fistula may significantly alter the intrapulmonary distribution of ventilation, ventilation-perfusion matching and arterial blood gases. Prompt localization of surgical closure of bronchopleural fistula remains the treatment of choice in most patients. We had a chance to use a Univent tube with movable blocker to the patients of bronchopleural fistula which developed during esophageal bougienation, The endotracheal tube has two compartment, a large lumen for conventional air passage and a small lumen where a movable tube is placed. Intubation a accomplished by ordinary technique, advancement of the bronchial tube to the right lowers bronchus being guided by fiberoptic bronchoscopy.
