title: Endoscopic evaluation of Barrett's esophagus.
abstract: Barrett's esophagus is a premalignant condition, the recognition of which is increasing because of widespread utilization of upper endoscopy. Awareness and identification of the squamocolumnar junction are key to endoscopic recognition of Barrett's esophagus. Biopsy is essential to document Barrett's esophagus and to detect dysplasia. Specific mucosal abnormalities need to be targeted. In addition, systematic biopsies need to be taken for dysplasia/carcinoma surveillance. Experimental endoscopic application of energy to Barrett's esophagus offers the potential for elimination of this lesion. Endoscopic recognition and diagnosis remain the key to clinical management of Barrett's esophagus.
