Clinical Significance of OLGA/OLGIM Staging Systems for Chronic Gastritis / 胃肠病学

ABSTRACT

The OLGA (Operative Link for Gastritis Assessment) grading and staging system is a semi-quantitative scoring of inflammation and atrophy based on updated Sydney system, the staging represents the topography, extension and severity of gastric atrophy, while the alternative staging system OLGIM (Operative Link on Gastric Intestinal Metaplasia Assessment) replaces the atrophy score with an assessment of intestinal metaplasia alone. The OLGA/OLGIM staging systems correlate the histopathological change of chronic gastritis with the risk of gastric cancer. Stages III and are associated with an increased risk of gastric cancer. Therefore, these staging systems can be used for gastric cancer screening, precancerous lesion monitoring and establishing individualized strategy for endoscopic surveillance.
