The patients will then be randomised to 2 groups of 50 patients each. 50 patients in one group will undergo Transtracheal (EBUS-TBNA) approach, whereas in the other group, 50 patients will undergo Transesophageal (EUS-B-FNA) route as the primary approach using the EBUS scope. Procedures will be performed under moderate sedation. Procedures will be performed in the Bronchoscopy Lab.
