Randomized Controlled TrialCytologic assessment of endobronchial ultrasound-guided transbronchial needle aspirates in sarcoidosis.
The purpose of this study was to determine interobserver variability, the relative importance of cytologic preparations, and factors influencing the diagnostic yield of mediastinal lymph node aspirates in suspected sarcoidosis. ⋯ Liquid-based cytology and cell block specimens are equally important in maximizing the diagnostic yield in EBUS-guided and conventional TBNA in suspected sarcoidosis. Good interobserver agreement between cytopathologists was noted, with improved diagnostic yield after review by a pulmonary cytopathologist. None of the clinical factors assessed impacted on the diagnostic yield of the procedure on a per-node basis.
