The introduction of EBUS improves the sensitivity and reliability of TBNA in the staging of lung cancer (1).
The most recent American College of Chest Physicians guidelines on the management and treatment of lung cancer recommend EBUS as the initial step in the diagnostic staging of lung cancer (21).
EBUS cannot sample all mediastinal lymph node stations and is usually combined with EUS for a more thorough and systematic sampling of the mediastinum.
EBUS is less invasive, more accurate, and can be performed time and time again without the limitations that prevent mediastinal restaging by mediastinoscopy.
A randomized trial of the use of EBUS in the guidance of TBNA procedures has been reported previously .
The end diagnosis made by conventional TBNA was tuberculosis in 13 of 20 cases (65%) cytologically , whereas in our study the diagnostic value of EBUS TBNA was 60% in tuberculosis (6 out of 10).
4%) were successfully diagnosed by EBUS guided TBNA with a 22-gauge needle.
