 Chronic gastritis has usually been diagnosed by histological examinations because of discrepancy between histological and endoscopic findings. However, recent advances in endoscopy have gradually elucidated endoscopic findings that correspond with histological changes. Based on Helicobacter pylori(H. pylori)infection, the gastric mucosa is divided into the following three states:normal mucosa without a history of H. pylori infection(non-gastritis), currently active H. pylori infection(active gastritis), and past history of H. pylori infection(inactive gastritis). In the Kyoto classification of gastritis, a novel classification system, 19 endoscopic findings related to gastritis are characterized based on H. pylori infection. Regular arrangement of collecting venules, diffuse redness, and map-like redness are highly specific characteristic features of each of the aforementioned states. Since the risk and characteristics of gastric cancer differ among the three states, endoscopic evaluation of gastric mucosa is important for screening of gastric cancer.
