2.Observe the endobronchial route as usual and visualize the lesion using radial EBUS (R-EBUS) through a GS.

3.Position the GS in the lesion, as appropriate, and remove the R-EBUS probe. Then, insert the TBNA apparatus with the covering metallic sheath into the GS.

4.An assistant pushes the needle toward the lesion under simultaneous X-ray fluoroscopy guidance.

5.After jabbing the target lesion, the assistant creates a negative pressure through the 20-ml syringe and moves the TBNA apparatus back and forth. Note that instead of the operator, the assistant is the one who performs the needle aspiration, while the operator secures the position of the scope and GS (Fig. 19.2).
