In the past patient suspected to have sarcoidosis with negative transbronchial biopsy were referred for mediastinoscopy, the availability of EBUS TBNA is a less Invasive safe and more economical alternative for obtaining a pathologic diagnosis of mediastinal lymph nodes.
Accumulation of the following five risk factors predicted a positive TBNA result: lymph node size greater than 2.5 cm, the presence of an endobronchial lesion, visible airway distortion during bronchoscopy, malignant diagnosis, and primary lesion in lung parenchyma.
Under nonlimiting N, despite the N dilution phenomenon, the contrasting values of FDM and TBDM corresponded to similarly contrasting values of FNA and TBNA since the N concentration did not significantly vary among genotypes.
Once the target lymph nodes or tumor is identified, TBNA is performed.

Compared to common site of mediastinal and hilar lymph nodes, the indications for TBNA of peribronchial lesion remained limited.
In the present study, USG/CT guided FNAC as well as CNB of anterior mediastinal masses and FOB with TBNA and IHC markers could diagnose 9 cases of NHL, 4 cases of bronchogenic carcinoma, 4 cases of thymoma, 1 case of retrosternal thyroid, 1 case of synovial sarcoma and metastasis in 1 case.
Cervical mediastinoscopy remains the gold standard to which all other techniques like CT scan, PET scan, TBNA and EUS guided aspiration are to be compared6,7.
Similarly, the diagnostic yield of FB for mediastinal lymph nodes using transbronchial needle aspiration (TBNA) is reported to be between 15-83% [21].
(2) Often, TBNA is the only material available for both the diagnosis and the molecular testing that are required for patient care.
The pooled OR for EBUS-TBNA + TBLB + endobronchial biopsy (EBB) versus TBNA + TBLB + EBB was 1.54 (95% CI, 0.61–3.93, P = 0.36), implying that there was no significant difference between their diagnostic yields.
