Popis: | 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 institution were evaluated. All cases were performed by a single operator formally trained in interventional pulmonology. Both Olympus 19- and 22-G needles were used at each lymph node station in an alternating manner. Rapid on-site cytology evaluation was used and a separate cell block was prepared for each needle at each station. RESULTS Fifty-six lymph nodes were analyzed. Diagnoses included cancer (36%, including 1 lymphoma), reactive lymphoid tissue (53%), and sarcoidosis (11%). One hundred sixty-two and 163 passes were made with the 22- and 19-G needle, respectively. Sample adequacy was 73% and 46% with the 22 and 19-G needle, respectively (P |
