Operative link on gastritis assessment stage is an appropriate predictor of early gastric cancer

Figure 1 Endoscopic atrophic pattern described by Kimura-Takemoto[11]. The spread of atrophic gastritis is divided into closed-type gastritis (C-type) and open-type gastritis (O-type). C-1 represents highly localized antral gastritis, and C-2 and C-3 represent increasing extension through the lesser curvature and greater curvature, respectively. O-type indicates gastritis reaching the cardia, with O-1 reaching the lesser curvature, O-2 reaching half of the stomach, and O-3 having extensive atrophic gastritis, affecting almost the entire stomach.
