Conventional method and ultrasound guided transbronchial needle aspiration techniques in the diagnosis of intrathoracic lymphadenopathies

Conventional transbronchial needle aspiration (TBNA) is one of the minimally invasive methods used for the diagnosis of intrathoracic lymphadenopathies, which is an effective, safe and cheap bronchoscopic technique. Endobronchial ultrasound (EBUS) guided TBNA is one of the most important advances in pneumology in recent years and has extended the diagnostic spectrum of bronchoscopic techniques. Today there are two different types of ultrasound probes for use with EBUS: radial and convex. The most important advantage of convex probe EBUS is that it allows real-time imaging while sample taken. To increase the diagnostic success, expansion of both conventional and ultrasound guided TBNA applications may reduce the need for invasive surgical procedures
