The concept of chronic gastritis has always been controversial. With the aim of avoiding diagnostic confusions, a classification and grading system was established at a meeting held in Sidney (Australia). The objective of this study was determining the utility and possibility of reproduction of the Sidney System for grading and classifying chronic gastritis and determining its correlation with endoscopic diagnosis. The study included 55 patients submitted to upper gastrointestinal endoscopy and in whom the diagnosis of chronic gastritis was established; the study was descriptive, prospective, and longitudinal. A classification of the endoscopic findings based on the Sidney classification was used as visual guide, a classification which was also proposed for the histopathologic reading. The diagnosis of chronic gastritis was corroborated by histopathology in all patients. The predominant endoscopic finding was patchy erythema or linear erithema, present in 98,2% of patients. There was no endoscopic-histopathologic correlation in respect to anatomic location (antral-antrocorporeal) or to grading (levels of severity). Important relationships were registered between the endoscopic signs of hiperplasia and nodularity and the presence of Helicobacter pylori, the presence of incomplete intestinal metaplasia at the incisura angularis and H. pylori – activity (neutrophiles). We recomended the use of the visual guide for unifying diagnostic criteria and nomenclature and we have corroborated the utility and reproducibility of the Sidney System.
