Randomized Controlled Trial
Bronchoscopy Using Virtual Navigation and Endobronchial Ultrasonography with a Guide Sheath (EBUS-GS) with or without Fluoroscopy for Peripheral Pulmonary Lesions.
Endobronchial 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. ⋯ There was a possibility that VBN-guided EBUS-transbronchial diagnosis without fluoroscopy might be equivalent to that under fluoroscopy. Further multi-center randomized study may be desired. (UMIN000008592).
