Core Tip

Core Tip: Imaging advances in endoscopy significantly improved our diagnostic capability. While magnification endoscopy is well incorporated in Asian countries, in Western countries most upper endoscopes devices are not equipped with this feature. In this study, we evaluated the near focus technology to access mucosal surface pattern and correlate with Helicobacter pylori infection. We believe this article will be of great interest to endoscopist in the Western, as there is still a room for better understanding gastric mucosal surface pattern and near focus technology.
