Bronchial Physiological Saline Injection to Visualize Peripheral Pulmonary Lesions in Ultrathin Bronchoscopy.

ABSTRACT: Background: During bronchial lavage, the lumen can be viewed better by injecting physiological saline into the bronchus. This study aimed to investigate the effect of injecting physiological saline into the bronchus while directly observing the bronchial lumen with peripheral pulmonary lesions using an ultrathin bronchoscope. Methods: We evaluated changes in the depth of field and signal-to-noise ratio due to saline immersion in bronchoscopic images captured with line patterns. We injected physiological saline through the working channel into the bronchial lumen and directly observed the lesions (mainly in cases of suspected peripheral lung cancer) in 38 patients using white-light and narrow-band imaging. Ultrathin bronchoscopic findings and histopathological diagnoses were a
