Abstract
Background: Encloscopic 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.
Methods: A step-by-step description of the linear EUS-FNA procedure as performed in our hospital will be provided. Ultrasonographic Landmarks will be shown on images. The procedure will be related to published literature, with a systematic literature search.
Results: EUS-FNA is an outpatient procedure under conscious sedation. The typical linear EUS-FNA procedure starts with examination of the retroperitoneal area. After this, systematic scanning of the mediastinum is performed at intervals of 1-2cm. Abnormalities are noted, and FNA of the abnormalities can be performed. Specimens are assessed for cellularity on-site. The entire procedure takes 45-60min.
Conclusions: 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. (C) 2004 Elsevier Ltd. All rights reserved.
