Objectives: To assess the diagnostic value of endoscopical findings compared to histopathological diagnosis, to delineate the relative frequency and pattern of different types of gastritis and their association with H. pylori and intestinal metaplasia in our locality, and to compare the results of this study with those of others. Methods: In a cross sectional study 150 selected patients with different upper gastrointestinal symptoms have been examined at endoscopy units in Ibn-Sina teaching hospital and Al-Jamhori teaching hospital in Mosul city, from the first of June 2013 to the first of March 2014, all were assessed endoscopically and biopsies from both antral and body mucosa were taken for histopathological examination. Results: This study has revealed gastritis histopathologically in 96.6% of cases, and the agreement between endoscopical and histophathological diagnosis was 88%. The chronic superficial gastritis represented the highest relative frequency  in this histopathologically diagnosed gastritis, where it was seen in 61.3% of the cases and it’s relative frequency decreased with advance age, while chronic atrophic gastritis was diagnosed in 30% of the cases and it’s relative frequency increased with advanced age, while gastric atrophy wasn’t detected in any case. Acute gastritis was detected in only 5.3% of the cases.    Helicobacter pylori was detected in 67% of cases. A significant association was detected between chronic gastritis and Helicobacter pylori infection, and its frequency decreased with increased severity of glandular atrophy. Follicular gastritis was diagnosed in 51% of chronic atrophic gastritis and 91.3% of them were Helicobacter pylori positive cases. By the use of the special stain AB/PAS pH (2.5), intestinal metaplasia has been diagnosed in 23% of cases and it’s relative frequency increased with advanced age. Conclusion: There is a high rate of concordance (88%) between endoscopical findings and histopathological diagnosis of gastritis. Among gastritis chronic variety was the commonest. H. pylori had a significant association with chronic gastritis (chronic superficial gastritis and chronic atrophic gastritis). Intestinal metaplasia has been detected mainly in chronic atrophic gastritis and its frequency increased with advanced age.
