Comparative Analysis of Results of Transbronchial Needle Aspiration Biopsy of Mediastinal Lymph Nodes with Flexible and Rigid Tracheobronchoscopy for Verification of Mediastinal Lymphadenopathies

The objective: to analyze results of TBNA for diagnosis mediastinal lymphadenopathy performed with flexible and rigid tracheobronchoscopy needles different diameters. Subjects Methods. We analyzed data 194 patients who underwent fibrobronchoscopy (Group 1) or bronchoscopy 2) uncertain etiology. Results. overall diagnostic efficacy the biopsy was 90,7%, while in case tumors, sensitivity 89,5% specificity 97,5%, respiratory sarcoidosis, they were 92,5% 85,9%, respectively. Better rates observed Group 1 (flexible 19G puncture needles) versus 2 (rigid 16G which may be due small number biopsies 2.
