Endobronchial Ultrasonography (EBUS) is a valuable diagnostic method that plays a critical role in the diagnosis and staging of enlarged lymph nodes and masses within the thoracic cage, associated with various conditions such as lung cancer, infectious diseases, sarcoidosis, lymphoma, rheumatological diseases, and tuberculosis. It is recommended by international guidelines as the first-choice minimally invasive method for lung cancer staging. The EBUS procedure enables the diagnosis and staging of lung cancer without requiring surgery and generally without hospitalization. Due to this characteristic, it offers a suitable and important alternative method for patients at high risk for surgical intervention. The diagnostic accuracy of EBUS ranges from 76% to 95%, depending on the specific disease.
