Background:Endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive procedure with a high diagnostic yield for mediastinal and central pulmonary lesions. This procedure is especially useful for lung cancer diagnosis, staging and also for the diagnosis of benign pathologies.

Methods: From January 2018 to May 2022, we included 105 patients with a mediastinal or mediastinal-pulmonary mass requiring EBUS TBNA.This is a retrospective study wich took place in the Functional Respiratory Exploration and Interventional Endoscopy department of EHU Oran Algeria.The aim is to determine the contribution of EBUS TBNA in the diagnosis of mediastinal-pulmonary pathologies. All patients had a chest CT scan,4 only a PET CT scan.

Results: 99/105 patients benefited from an EBUS TBNA with awake sedation and only 4 patients with ROSE. 50 women versus 49 men with sex ratio = 1 , average age was 52 with extremes (16-82). The Results were distributed according to the positivity of the samples as follows: 72 conclusive results (72%) including: 15 bronchial cancers, (21%), with 1/15 operable. 2 Lymph node metastases from bronchial cancer (staging), (3%). 6 Lymph node metastases from extra-thoracic cancer (8%). 3 Lymphoma (4%). The absence of lymph node infiltration in a current or in remission neoplastic context was noted in 8 patients (11%). 25 sarcoidosis (34%). 10 Tuberculosis (14%). 4 Unspecified granuloma (5%).No complications were noted during the procedure.

Conclusions:The EBUS TBNA is an innovative technique in Algeria, reproducible less invasive than other procedures allowing an important contribution in the diagnosis of mediastinal pathologies requiring pulmonologists and trained anatomopathologists.
