VBN-EBUS-GS-TBLB With or Without Fluoroscopy for the Diagnosis of PPLs

VBN is carried out by a VBN software（DirectPath; Olympus, Japan) which can automatically create virtual bronchoscopic images.

EBUS is performed using an endoscope ultrasound system , which is equipped with a 20-MHz mechanical radial-type probe (UM-S20-17S;Olympus) with an external diameter of 1.4 mm and a GS (K-201; Olympus).

The radiograph fluoroscopy are performed when the probe and GS are confirmed to reach the lesion by EBUS images ,cytologic and pathologic specimens are obtained under fluoroscopic guidance.
