Abstract

This study aimed to evaluate atrophic gastritis (AG) using the Kimura-Takemoto classification in endoscopic imaging and compare it with histopathological findings. A prospective study was conducted on 181 patients diagnosed with AG by endoscopy at the Hospital of the Post Office And Telecommunications. Endoscopic features and histopathological results were analyzed to determine the correlation between AG severity and histological lesions. The findings revealed that the most common atrophic type was C2 (28.7%), followed by C1 (25.9%) and C3 (22.7%). O1, O2, and O3 were less frequent (13.2%, 7.2%, and 2.2%, respectively). The severity of AG was classified as mild (54.7%), moderate (35.9%), and severe (9.4%). The prevalence of Helicobacter pylori infection was 65.2%, while intestinal metaplasia was observed in 46.4% of cases. A significant correlation was found between AG severity and chronic inflammation (p = 0.01), active inflammation (p < 0.01), histological atrophy (p < 0.05), intestinal metaplasia (p = 0.01), dysplasia (p < 0.05), and H. pylori infection (p < 0.05). The Kimura-Takemoto classification is a practical and effective endoscopic method for diagnosing AG.
