Utility and safety of endobronchial ultrasound-guided transbronchial needle aspiration in patients with mediastinal and hilar lymphadenopathy: Western region experience.

Abstract:

AIMS:The aim of the study was to evaluate the clinical utility and safety of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in patients with mediastinal and hilar lymphadenopathy and to explicitly describe the utility of this procedure in patient's outcome. METHODS:A retrospective review and analysis was conducted on 52 patients with mediastinal or hilar lymphadenopathy who underwent EBUS-TBNA from June 2012 to June 2016. All the patients were evaluated by computed tomography (CT) chest with contrast before EBUS examination. Enlarged mediastinal or hilar lymph node was defined as >1 cm short axis on the enhanced CT. RESULTS:Among the 52 patients studied, 57.7% were presented with mediastinal or hilar lymphadenopathy for diagnosis and 42.3% presented with suspected mediastinal malignancy. Paratracheal stations were the most common site for puncture in 33 lymph nodes (43%). The best diagnostic yield was obtained from subcarinal stations and the lowest yield from the hilar stations. Surgical biopsies confirmed lymphoma in six patients, tuberculosis (TB) in three, sarcoidosis in two and one had metastatic adenocarcinoma of unknown primary. The sensitivity, specificity, positive predictive value, and negative predictive value of EBUS-TBNA for diagnosis of mediastinal and hilar lymph node abnormalities were 78.6%, 100%, 100%, and 80%, respectively. The diagnostic yield of EBUS-TBNA in malignant and benign conditions was 79.0%. CONCLUSIONS:EBUS-TBNA is a safe and efficacious procedure which can be performed using conscious sedation with high yields. It can be used for the staging of malignancies as well as for the diagnosis of inflammatory and infectious conditions such as sarcoidosis and TB.
