The Role of Convex Probe Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration in the Diagnosis of Hilar and Mediastinal lesions

Abstract

In the staging of lung cancer or in the presence of mediastinal lymphadenopathy invasive diagnosis of mediastinal lesions is fundamental. Despite imaging methods advances, tissue samples are essential for diagnostic confirmation and treatment planning (Pillot et al., 2006).

for collecting material for cytology less invasive methods recently have emerged as an alternative endobronchial ultrasound (EBUS), Among these methods, developed in the past decade, as an outpatient method and allows access to hilar stations in addition to paratracheal stations, for detection and collecting material from lymph nodes less than 1 cm (Whitson et al., 2007).
