EBUS-TBNA endoscopy department experience Republican Clinical Oncology Dispensary

The aim of the study was to evaluate the feasibility of using endobronchial ultrasound (EBUS-TBNA) for the diagnosis of unspecified lymphadenopathy, peribronchial lung neoplasms and mediastinal formations. A retrospective analysis of 339 EBUS-TBNA studies from 2021-2024 using an ultrasound bronchoscope followed by a fine needle aspiration biopsy was performed. The diagnostic accuracy of EBUS-TBNA was 80.3%. Non-squamous cell non-small cell lung cancer accounted for 45.6%, due to their highest percentages of mediastinal forms and lymphadenopathy. There were no clinically significant complications. EBUS-TBNA is an effective method of sampling for the diagnosis of mediastinal formations and peribronchial bronchial tumors for cytological and histological examination and has advantages over other verification methods, primarily for comorbid patients.
