Advantages and drawbacks associated with the use of endosonography in sarcoidosis.

EBUS-TBNA is a minimally invasive, safe procedure with a good diagnostic yield, and should be the preferred diagnostic modality for sampling intrathoracic lymph nodes in patients with suspected sarcoidosis. For optimal diagnostic yield, EBUS-TBNA should be combined with endobronchial biopsy (EBB) and transbronchial lung biopsy (TBLB). Newer endosonographic techniques like EBUS-IFB and EBMC might obviate the need for EBB and TBLB due to their superior diagnostic yield.
