Surrounding Gastric Mucosa Findings Facilitate Diagnosis of Gastric Neoplasm as Gastric Adenoma or Early Gastric Cancer

This atrophic border is the boundary between the pyloric and fundic gland regions, which can be recognized endoscopically based on the difference in color and height of the gastric mucosa on either side of the border. There are four types of endoscopic atrophic gastritis: C0-C1, C2-C3, O1-O2, and O3-Op.
