Abstract
Background: EBUS-TBNA represents a new technology in the field of bronchoscopy The primary indications for EBUS-TBNA are staging NSCLC and the diagnostic assess-ment of mediastinal lymphadenopathy. EBUS-TBNA also has a diagnostic role in suspected benign disease, especially sarcoidosis and tuberculosis. It is a minimally invasive option as the first sampling staging procedure in suspected NSCLC with solitary hilar nodes, discrete N2 or N3 or bulky medias-tinal diseaes.
Aim of Study: The aim of the work is to estimate role of Endbronchial Ultrasound (EBUS)in staging of lung cancer.
Patients and Methods: It is a prospective experimental selected non cohort study that carried out on 20 patients with bronchogenic carcinoma addmited to Tanta University Hos-pitals from April 2016 till November 2016.
Results: In the current study, 20 patients (17 males & 3 females) were included to examine subcarinal, hilar and mediastinal lymph nodes (LN) in different stations. Among the 20 patients examined, 7 of them were under 60 years and 13 were above 60 years 17 of them are smokers and 3 patients are non-smokers. According to type of lung cancer 4 patients were adenocarcinoma, 5 patients were large cell carcinoma, 6 patients were small cell carcinomas and 5 patients were squamous cell carcinomas. In the current study the lymph nodes staging of lung cancer were N1 (9 patients), N2 (8 patients) and N3 (3 patients).
Conclusions: Endobronchial ultrasound-guided transbron-chial needle aspiration has a high diagnostic yield for the evaluation of mediastinal and hilar lymph node metastasis in lung cancer and has a high impact on patient management.
