Abstract
Gastric cancer is the second highest cause of cancer-related deaths worldwide. Intestinal metaplasia (IM) has been known to be a premalignant lesion or condition; however there is no gold standard for diagnosing IM. Although several useful techniques combined with the aid of endoscopy have been suggested to accurately diagnose IM, the cost-effectiveness of these modalities has been questioned. Recently, a widely used high-resolution endoscopy made it possible to observe even the mucosal pit pattern and improve diagnostic accuracy of mucosal lesions. The aim of this study was to assess the interobserver variability and accuracy of the high-resolution white-light endoscopy as a diagnostic tool for IM.
