The Effect of Aspiration Pressure Over Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration on the Diagnosis of Intrathoracic Lymphadenopathies

Background Data regarding the effect of aspiration pressure over endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) on the diagnosis of intrathoracic lymphadenopathies is limited. The aim of this study was to compare the effect of three levels of aspiration pressure over EBUS-TBNA on the diagnostic yield and numbers of diagnostic cells.
