Biopsy Sites Suitable for the Diagnosis of Helicobacter pylori Infection and the Assessment of the Extent of Atrophic Gastritis

Abstract

Our results indicate that for an accurate diagnosis and assessment, biopsies should be taken from the following four sites: the lesser curvatures of the mid-antrum (site 1) and middle body (site 3), and the greater curvatures of the mid-antrum (site 4) and middle body (site 6) of the stomach.
