Abstract

Barrett's esophagus requires surveillance to monitor for dysplasia and esophageal adenocarcinoma. New methods have been developed to detect dysplasia and esophageal adenocarcinoma. One of these methods, the wide area transepithelial sampling 3D brush biopsy (WATS 3D) is a computer-assisted brush-biopsy technique that uses an abrasive sampling instrument to detect dysplasia or esophageal adenocarcinoma compared to the standard four quadrant biopsy method. This case illustrates a patient with esophageal adenocarcinoma diagnosed by WATS 3D initially diagnosed as high-grade dysplasia and treated appropriately with HALO procedure during esophagogastroduodenoscopy. We aim to demonstrate the clinical utility of WATS 3D in Barrett's surveillance.
