These findings confirmed the high accuracy (exceeding 90%) of lung cancer diagnosis obtained using EBUS-TBNA, both with and without a stylet, supporting the use of TBNA needles without a stylet.
Once the target lymph nodes or tumor is identified, TBNA is performed.
Accumulation of the following five risk factors predicted a positive TBNA result: lymph node size greater than 2.
Under limiting N, FNA and TBNA were 18 and 24%, respectively, of those under nonlimiting N, while percentages for FDM and TBDM were 38 and 65% (Tables 2 and 3).
Once the target lymph node was identified, the probe was then removed from the working channel, and the needle was placed through the sheath and remained in place in order to stabilize the lesion during the TBNA [7,13].
The diagnostic yields of transbronchial needle aspiration (TBNA) and TBNA + transbronchial lung biopsy (TBLB) are 62% and 83%, respectively.
Under the guidance of elastosonography, the positive diagnosis rate of TBNA can be improved, unnecessary punctures can be reduced, the time of operation can be shortened, and the occurrence of false positives can be avoided.

Lung cancers are increasingly diagnosed and staged by transbronchial needle aspiration (TBNA), endobronchial ultrasound-guided TBNA, and endoscopic ultrasound-guided fine-needle aspirations.
Additionally, the image guided component increases yields versus traditional "blind" TBNA techniques.
