Abstract

Objective: Endobronchial ultrasound – guided tranbronchial neede aspiration (EBUS-TBNA) is a new method for the diagnosis of mediastinal lesions located adjacent to the central airway. The purpose of this study was to evaluate the result of EBUS-TBNA for the diagnosis of mediastinal lesions.

Methods: We descriptively studied the results of patients who underwent EBUS-TBNA between 6/2021 to 6/2022. Final diagnosis were determined by EBUS-TBNA, surgery and (or) clinical follow-up.

Results: A total of 81 patients, of whom 52 (64,2%) were male and 29 (35,8%) were female. The mean age was 55,20±14,47 years. The final diagnoses were 35 malignant mediastinal and 46 benign mediastinal. The EBUS-TBNA was diagnostic in 70 of 81 patients: Malignant 31, tuberculosis 25, nonspecific inflammatory 10, mediastinal goiter 1, sarcoidosis 2, normal 1. The diagnostic accuracy of EBUS-TBNA was 86,4%, 84,8% for benign lesions and 88,6% for malignant lesions. The sensitivity, specificity, positive predictive value, negative predictive value was 85,7%, 100%, 100% and 91,5% respectively. There were no complications.

Conclusions: The diagnostic value of EBUS-TBNA is high for mediastinal lesions located adjacent to the central airway.
