Classification of an endoscopically evident atrophic pattern. The atrophic border is the boundary between the pyloric and fundic gland territories, which is endoscopically recognized by discriminating differences in the color and height of the gastric mucosa. Cases of closed-type GMA have an atrophic boundary between the fundic mucosa and the pyloric mucosa in the antrum or lesser curvature of the gastric body. Cases of open-type GMA have an atrophic boundary in the lateral wall or greater curvature of the gastric body [8]. C, closed; O, open.
