dc.description.abstractIntroduction: Endobronchial ultrasound (EBUS) elastography is an imaging procedure for describing the elasticity of intrathoracic lesions and provides important additional diagnostic information. Objective: The purpose of this study was to compare the elastographic patterns of lymph nodes with the outcomes from endobronchial ultrasound- guided transbronchial needle aspiration in order to assess the usefulness of endobronchial ultrasound elastography for mediastinal and hilar lymph nodes. Material and methods: A total of 52 lymph nodes were examined. Endoscopic ultrasound processor and a convex probe endobronchial ultrasonography were utilized to evaluate elastographic patterns that were categorized according to color distribution as follows: Type 1, which consists primarily of non-blue colors (green, yellow, and red); Type 2, which consists partly blue, partly non-blue (green, yellow and red); and Type 3, which consists of predominantly blue colors. The ultimate pathologic outcomes of the endobronchial ultrasound- guided transbronchial needle aspiration were compared to the elastographic patterns. Results: On pathological evaluation of the lymph nodes, 11 were found to be benign and 41 were malignant. The lymph nodes that were classified as Type 1 on endobronchial ultrasound elastography were benign in 8/8 (100%); for Type 2 lymph nodes, 3/9 (33.3%) were benign and 6/9 (66.6%) were malignant; Type 3 lymph nodes were benign in 3/35 (8.5%) and malignant in 32/35 (91.4%). In classifying Type 1 as 慴enign� and Type 3 as 憁alignant,� the sensitivity, specificity, positive predictive value and negative predictive values were 85.3%, 81.8%, 94.59%, and 60%, respectively. Conclusions: It is possible to predict nodal metastases during endobronchial ultrasound-guided transbronchial needle aspiration using the noninvasive endobronchial ultrasound elastography of mediastinal and hilar lymph nodes.en_US
