Endoscopic Ultrasound for Evaluation of High-Grade Dysplasia in Barrett's Esophagus

In the past decade, endoscopic ultrasound (EUS) has become an important imaging modality in the management of several gastrointestinal disorders. Given its ability to provide detailed images of the layered structure of the esophageal wall and of the surrounding structures, EUS has been proposed as a potentially sensitive method to evaluate patients with Barrett's esophagus, in particular those with high-grade dysplasia (HGD) and early adenocarcinoma. This article reviews the role of EUS for imaging Barrett's esophagus, with particular emphasis on the available studies dealing with the clinical relevance of EUS in the management of patients with Barrett's esophagus and HGD and early adenocarcinoma.
