FICE: Fujinon intelligent chromoendoscopy; SIM: Specialized intestinal metaplasia; HGD: High-grade dysplasia; LGD: Indicate Low grade dysplasia.

¹Endoscopists were not able to exactly classify the mucosal pattern according to Sharma’s classification of mucosal pattern due to lack of visibility, but they judged that the mucosa was regular.
