Bronchoscopy Using Virtual Navigation and Endobronchial Ultrasonography with a Guide Sheath (EBUS-GS) with or without Fluoroscopy for Peripheral Pulmonary Lesions

摘要

ObjectiveEndobronchial ultrasonography and guide sheath (EBUS-GS) technique has high diagnostic yield in lung nodules. Virtual bronchoscopic navigation (VBN) can lead bronchoscope to the target bronchi. The aim of this prospective study was to compare the diagnostic yield of two bronchoscopic procedures: bronchoscopy under EBUS-GS and VBN with or without x-ray fluoroscopy in small peripheral pulmonary lesions (PPLs, ≤30mm) with apparent CT-bronchus sign.
