Clinical Application of the Kyoto Classification of Gastritis

Recent advances in endoscopic technology, including high-definition and image-enhanced endoscopy such as narrow-band imaging have facilitated close observation detailed of the gastric mucosa. Currently, is performed Korea primarily for evaluation premalignant conditions cancer detection. research has established Kyoto classification gastritis, a novel grading system which enables prediction Helicobacter pylori (H. pylori) infection. The score calculated based on sum scores five main items (of 19 findings indicative H. infection) atrophy, intestinal metaplasia, enlarged folds, nodularity, diffuse redness with/without regular arrangement collecting venules (RAC). Of these findings, nodularity are associated with an increased risk RAC decreased cancer. Previous studies reported that ≥2 indicates current or past An increase high cancer; specifically, ≥4 However, eradication followed by disappearance redness; therefore, this cannot accurately reflect patients previous Limited discussed gastritis Korea. Therefore, further large-scale multicenter warranted validation to predict infection risk.
