 It is essential to diagnose chronic gastritis and gastric intestinal metaplasia to stratify the risk of gastric cancer. Lesions representing chronic gastritis and gastric intestinal metaplasia require a differential diagnosis from gastric cancer. Gastric cancer is typically characterized by the presence of mucosa surrounding it, which is associated with its boundary diagnosis. Many studies have reported gastritis classifications on the basis of microvascular patterns and microsurface structures using magnifying endoscopy with NBI(narrow-band imaging). The normal gastric fundus gland mucosa without Helicobacter pylori infection has a foveola-type structure, whereas advanced chronic gastritis mucosa with severe atrophy and intestinal metaplasia has a groove-type structure. With the finding of intestinal metaplasia using magnifying endoscopy with NBI, several other findings such as a light-blue crest ; a white, opaque substance ; a marginal turbid band ; and a ridge/villous pattern have also been reported.
