[Gastric erosions: pathogenesis, clinical features, diagnosis, and treatment].

Recent data on etiology, pathogenesis, diagnosis, and treatment of gastric erosion are reviewed. Classification of acute and chronic erosions is proposed. The authors point out to the lack of documented scientific information related to the role and significance of erosions in gastroduodenal pathology. Special emphasis is laid on risk factors, diagnosis, prevention, and treatment of gastropathies with reference to their clinical features and diagnostic criteria. The main provisions of the Maastricht Treaty 3 (2005) concerning NSAID gastropathies are outlined.
