Yamasaki A, Shimizu T, Kawachi H, et al. - In this retrospective study involving 130 patients (141 lesions), researchers identified the endoscopic features (macroscopic type, localization, and color) and clinicopathological differences in superficial Barret esophageal adenocarcinoma (s-BEA) derived from short-segment Barrett esophagus (SSBE) and long-segment Barrett esophagus (LSBE). Data of patients with pathologically confirmed s-BEA were reviewed. In patients with SSBE and LSBE, endoscopic and clinicopathological features of s-BEA were analyzed. Findings revealed that there was a significantly greater prevalence of flat-type, accompanied-type 0-IIb and complex-type lesions in LSBE. In addition, complex-type s-BEAs tended to have T1b invasions and components that were poorly differentiated. On endoscopic appearance, including flat-type and complex-type lesions, S-BEAs in LSBE should be evaluated more carefully than in SSBE.
