Endobronchial ultrasound diagnostic yield for sarcoidosis in hilar <i>vs</i>. mediastinal lymph nodes.

ABSTRACT:

Background

Pulmonary sarcoidosis is diagnosed by endobronchial ultrasound-guided transbronchial needle aspirate (EBUS-TBNA) of hilar and mediastinal lymph nodes and the finding of non-caseating granulomatous inflammation. There are currently no guidelines about which lymph node stations to sample to optimize the diagnostic yield and it is unclear if there is a difference in the yield between hilar and mediastinal lymph node stations. The objective of this study was to assess the difference in the diagnostic yield of EBUS-TBNA for non-caseating granulomas between hilar and mediastinal lymph nodes.

Methods

A retrospective study was performed and medical records were reviewed of all patients at a single institution who underwent EBUS-TBNA of thoracic lymph nodes to evaluate for
