 Evaluating the prevalence of gastritis by magnifying endoscopy is useful for estimating the risk of gastric cancer. Moreover, understanding the endoscopic appearances of gastritis is important for diagnosing gastric cancer using magnifying endoscopy.

 Regular arrangement of collecting venules and round crypt openings that are surrounded by a network of sub-epithelial capillaries represent predictive appearances of a normal corpus mucosa that is negative for Helicobacter pylori. In contrast, normal antral mucosa shows a ridged/papillary micro-surface pattern that encases coiled sub-epithelial capillaries. As atrophic gastritis progresses, the corpus mucosa, exhibiting round crypt openings, transforms into a ridged/papillary mucosa that is similar to the antral mucosa. Identification of a ridged/papillary mucosa with a light blue crest or white opaque substance represents predictive appearances of intestinal metaplasia.
