| [ Summary ] | In Japan, the number of patients having GERD or Barrett's esophagus has increased recently. However, Barrett's esophageal dysplasia and adenocarcinoma are often difficult to diagnose with conventional endoscopy. In Western countries, random biopsies are recommended for the surveillance of Barrett's esophageal dysplasia and adenocarcinoma. Narrow Band Imaging (NBI) using a magnifying endoscope (magnified-NBI) is a new technology developed to visualize fine vascular structures in the gastrointestinal mucosa. With magnified-NBI observation, Barrett's esophageal adenocarcinoma displayed various vascular patterns and mucosal structures. These findings were useful for detection and demarcation of the cancer margins. Magnified-NBI has the possibility of becoming a tool to diagnose Barrett's cancer in the early stages. |
