Inter- and Intra-Observer Variability of Magnification Chromoendoscopy for Detecting Specialized Intestinal Metaplasia at the Gastroesophageal Junction

Abstract

The suggested criteria for identifying SIM using magnification endoscopy are associated with a high level of interobserver variability. When evaluated in a blinded manner, staining techniques do not significantly improve the yield for detecting SIM at the esophagogastric junction.
