Comparison of Sample Adequacy and Diagnostic Yield of 19- and 22-G EBUS-TBNA Needles

Background: The 2016 CHEST consensus guidelines recommend use of either 21- or 22-G needles for endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). We decided to prospectively compare sample adequacy and diagnostic yield of the 19-G with the 22-G EBUS needle, hypothesizing that a larger gauge difference might magnify the differences between 2 needle sizes. Methods: Twenty-seven patients undergoing EBUS-TBNA at our...
