It should be assessed by the most efficient and safe, but also easy to learn in a clinical practice method.Objectives: The aim of this prospective, observational study was to evaluate the diagnostic yield and safety of thetransbronchial needle aspiration (TBNA) of peripheral lung lesions using radial EBUS mini-probe without disposable guide sheath (DGS).Methods: After systematic evaluationof lung CT-scansradial EBUS mini-probe without DGS was used to localizethe lesion. After then TBNA was performed and at least 3-4 biopsies were performed for cytological assessment.Results: 115 patients (M: 74, F: 41), mean age 68 years (31-85) were enrolled to the study since January to May 2015. A mean diameter of the lesion was 22mm (12-42). In analyzed 107 cases a cytological diagnosis was established, 66 lesions occurred to be malignant and 41 benign. The mean time time of the procedure was 15 minutes (10-23). Sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) for TBNA were 75%, 97%, 83%, 97% and 70%, respectively. No serious complications, including pneumothorax were observed.Conclusions: Radial EBUS mini-probe TBNA guided biopsy without DGS, is efficient, feasible and safe method for cytological diagnosis of peripheral lung lesions.
