Fig. 1. Metachronous gastric cancer after Helicobacter pylori eradication. (A) A 2.0 cm elevated mucosal lesion with a central depression (arrow) is identified on the anterior wall of the proximal antrum on the initial endoscopy. After endoscopic submucosal dissection, successful Helicobacter pylori is performed. (B) After six years of endoscopic treatment, surveillance endoscopy shows a surgical scar on the anterior wall of the proximal antrum. A 1.4 cm elevated mucosal lesion with central depression is shown on the greater curvature side of the high body. It is a metachronous lesion.
