Summary : Biopsy specimens can reveal that esophageal cancer is an adenocarcinoma but they cannot show that its origin is Barrett’s mucosa. Therefore we must show during endoscopy that the tumor exists in Barrett’s mucosa. We reported that Barrett’s esophagus could be clearly diagnosed at endoscopy as the columnar mucosa lying on the longitudinal vessels in the lower esophagus. We define Barrett’s esophagus as “the columnar mucosa in the esophagus which exists continuously more than 2cm in circumference from the stomach.” Short-segment Barrett’s esophagus (SSBE) is “the columnar mucosa which exists in the esophagus continuously from the stomach but its length has a part under 2cm in length.” Endoscopically Barrett’s adenocarcinoma is visualized as a lesion with a reddish and uneven mucosal surface. Barrett’s adenocarcinomas occur in the SSBE as well. Endoscopic observation at periodic intervals is necessary not only for cases with Barrett’s esophagus but also with SSBE. A further examination is necessary to determine the application of EMR for superficial Barrett’s adenocarcinoma.
