Endobronchial Ultrasonography-guided TBNA:A Conrparison of a Convex Type Endoscopic Ultrasound and an Ultrasonic Probe

Abstract

We compared the usefulness of EBUS-guided TBNA using a double-channel bronchoscope (Double) and EBUS-guided TBNA using a single-channel bronchoscope (Single) and endoscopic ultrasound (EUS). Patients. 85 patients with mediastinal and/or hilar lymphadenopathy were included. Patients were randomized to undergo Double (n=30) or Single (n=25) or EUS (n=30). Methods. Double: The EBUS probe and the 19-gauge TBNA catheter were inserted simultaneously through a double-channel bronchoscope. Once the needle place
