Efficacy of TBNA needles for EBUS during fiberoptic bronchoscopy?

Conventional transbronchial needle aspiration (cTBNA) biopsy is a diagnostic minimally invasive technique applied using fibreoptic bronchoscopy (FOB) in the evaluation of mediastinal/hilar lymph nodes. With development endobronchial ultrasound (EBUS) devices, needles have been revised for use according to EBUS guidelines. The main aim this research was evaluate success that produced when it with FOB instead conventional TBNA. A retrospective examination made data 35 patients TBNA, specifically designed and 36 TBNA (cTBNA group), lung cancer staging or diagnosis mediastinal lymphadenopathy between November 2018 2019. Seventy-two sixty procedures performed on 71 were included study. Diagnostic efficiency cTBNA groups 91.4% 83.3%, respectively. still acceptable low cost ease application are taken into consideration. In conclusion, improvement current similar EBUS-TBNA more efficient capacity could be first stepto increasing yield. Nevertheless, further studies needed confirm our results.
