EBUS is a well established minimally invasive diagnostic tool for mediastinal and hilar lymphadenopathy. The novel ViziShot Flex 19G needle (Olympus Respiratory America, Redmond, WA, USA) was introduced in 2015 in order to improve loaded scope flexion and to obtain larger tissue samples for analysis. The aims of this study were to assess diagnostic yield of Flex 19G needles and to present endoscopist's feedback about the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). ⋯ The first Polish experience with use of Flex 19G EBUS-TBNA needle occurs to be similar in performance with standard technique with use of 22/21G needles and presents high diagnostic yield for lung cancer diagnostics, especially when preparing CB. A safety profile of the biopsy is acceptable.
