Core Tip

Core tip: We report surveillance esophagogastroduodenoscopy (EGD) using trimodal imaging videoendoscopy (TME) to detect another lesion after endoscopic submucosal dissection (ESD) for superficial gastric neoplasia (SGN). In 242 surveillance EGDs, 16 early gastric cancers and 11 gastric adenomas were detected, 5 of which were missed by white-light imaging (WLI) but were detected by autofluorescence imaging (AFI). The five were whitish and protruded gastric adenomas. Sensitivity, specificity and accuracy in magnifying endoscopy with narrow-band imaging were higher compared to those in both WLI and AFI. Surveillance using TME is useful for detecting another lesion after ESD for SGN.
