Metastatic mediastinal lymph nodes from lung cancer EBUS-TBNA EBUS-TBLNC Lung cancer Neoplastic cell percentage
Conditions
Interventions
Once the target location is identified, TBNA is performed using a 21-gauge needle (NA-201SX-4021, Olympus), which punctured through the bronchial wall into the target LN. A suction syringe is then att
