| [ Summary ] |
Several Japanese studies reported chronic gastritis prior to the discovery of H. pylori infection. The Kyoto classification of gastritis was recently proposed based on previous H. pylori‒related research. Knowledge of the histopathological features associated with H. pylori‒infected gastritis is essential to understand the conventional endoscopic findings described in the classification. Irregular microvessels, inflammatory cell infiltration, structural changes in the microsurface and histological atrophy are features of the gastric mucosa observed in cases of H. pylori infection. It is also important to note that different topographical types of gastritis may concurrently occur in a patient. Clinicians should be aware of these H. pylori‒induced histopathological and micromucosal changes for accurate radiographic and endoscopic diagnosis of H. pylori gastritis. |
