Benign and Malignant Mediastinal and Hilar Lymph Nodes Known or Suspected Malignancy, ENDOBRONCHIAL ULTRASOUND - TRANSBRONCHIAL NEEDLE ASPIRATION
Conditions
Keywords
enlarged mediastinal nodes, enlarged hilar lymph nodes
Brief summary
The objective of this study is comparing the attributable procedural time of Endobronchial Ultrasound - Transbronchial Needle Aspiration (EBUS-TBNA) when sampling mediastinal and hilar lymph nodes with or without Rapid On-Site Evaluation (ROSE). The primary outcome will be the time elapsed from EBUS bronchoscope insertion to bronchoscope withdrawal. Secondary outcomes will include total number of sampled lymph nodes, average number of needle aspirations per lymph node sampled, overall diagnostic yield, and procedural time of the cytopathologist.
Interventions
The procedure will proceed with conventional EBUS-TBNA sampling of the target lesion with 22 gauge Vizishot needles. Each subject will be randomized to either ROSE by cytopathologist or no ROSE.
