Abstract: Background: Observational data suggest that the 19-gauge (G) needle for endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) offers a higher diagnostic yield in sarcoidosis than the 22-G needle. No randomized trial has compared the yield of the two needles. Methods: We randomized consecutive subjects with suspected sarcoidosis and enlarged thoracic lymph nodes to undergo EBUS-TBNA with either the 19-G or the 22-G needle. We compared the study groups for diagnostic sensitivity (primary… Show more
