Lung cancer is one of the most common neoplasms worldwide and a major cause of cancer death.Rapid diagnosis and accurate staging for patients with suspected lung cancer are essential to appropriate treatment.However,many of submucosal or parabronchial intrapulmonary lesions are invisible by bronchoscopy despite their adjacency to the central airway.Classical approaches in these cases,such as conventional bronchoscopy,transbronchial needle aspiration (TBNA) and computed tomography-guided transthoracic needle aspiration (TTNA),are of limited use in a sense of definitive diagnosis (1-3).With the advance in bronchoscopic diagnostics during the recent years,endobronchial ultrasound-guided TBNA (EBUS-TBNA)emerges as a novel technique for bronchoscopic sampling under ultrasound guidance.
