Core Tip
Core tip: Recent studies have reported that advances in magnifying endoscopy (ME) have led to better correlations between histopathological findings and the ME features of Helicobacter pylori (H. pylori)-induced gastritis. However, the ME findings regarding H. pylori-induced severe inflammation are insufficient. Therefore, we evaluated the relationship between H. pylori-induced gastritis and the whiteness of gastric mucosal crypt openings (COs) in the gastric corpus using ME. Our results showed that mononuclear cell and neutrophil infiltration differed significantly among the CO subtypes. CO whiteness detected via ME was associated with histological evidence of gastritis and helps to predict the severity of inflammation or activity induced by H. pylori in the gastric corpus.
