ReviewTechnical description of endoscopic ultrasonography with fine-needle aspiration for the staging of lung cancer.
Endoscopic ultrasonography (EUS) is a novel method for staging of the mediastinum in lung cancer patients. The recent development of linear scanners enables safe and accurate fine-needle aspiration (FNA) of mediastinal and upper abdominal structures under real-time ultrasound guidance. However, various methods and equipment for mediastinal EUS-FNA are being used throughout the world, and a detailed description of the procedures is lacking. A thorough description of linear EUS-FNA is needed. ⋯ EUS-FNA is minimally invasive, accurate, and fast. Anatomical areas can be reached that are inaccessible for cervical mediastinoscopy. EUS-FNA is useful for the staging of lung cancer or the assessment and diagnosis of abnormalities in the posterior mediastinum.
