Endoscopic and pathological features of gastric cancer after successful H. pylori eradication therapy. (a) Conventional endoscopic view showed a flat reddish lesion, but there was no marked difference between the cancerous area and surrounding non-cancerous area. (b) Chromoendoscopy by indigo carmine was used and it was still difficult to determine the border line of the lesion because of the metaplasia of mucosal background. (c) Histological examination confirmed epithelium with a low degree of atypicality (ELA) in the surface layer of a low cancerous lesion.
