Comparing the Clinical Performance of the New 19-G ViziShot FLEX and 21- or 22-G ViziShot 2 Endobronchial Ultrasound-guided Transbronchial Needle Aspiration Needles.

ABSTRACT: Objective Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure for pulmonary and mediastinal diseases. This study compared the performance of a novel 19-G needle with a 21- or 22-G needle. Patients and Methods Eleven patients at Okayama Medical Center were enrolled retrospectively between April and December 2017. Enlarged lymph nodes and a pulmonary nodule were sampled with both 19-G and 21- or 22-G needles in nine patients. Two patients underwent biopsies for suspected lymphoma with only the 19-G needle. We examined their medical records on the diagnosis, size of the lymph nodes and pulmonary nodule, and complications. Results The median longest diameter of the 13 lymph nodes (8 #7, 4 #4R, and 1 #11) and 1 pulmonary nodule (right s
