 We evaluated the endoscopic findings of superficial Barrett's esophageal adenocarcinoma by WLE(white light endoscopy). A total of 111 lesions were included, comprising 25 LSBE(long-segment Barrett's esophagus)lesions in 21 cases and 86 SSBE(short-segment Barrett's esophagus)lesions in 85 cases. Elevated lesions were observed in 14 of 25(56.0%)LSBE lesions and 55 of 86(64.0%)SSBE lesions. Regarding lesion color and type, 10 of 11(91.0%)LSBE lesions and 27 of 31(87.1%)SSBE lesions were erythematous. Further, 106 of 111(95.5%)lesions were detected to be elevated or erythematous by WLE. Regarding macroscopic type, complex- type lesions(i.e., type I+IIb, IIa+IIc, etc.)were observed in 13 of 25(52.0%)LSBE lesions and 28 of 86(32.6%)SSBE lesions. Type IIb or IIb lesions were observed in 10 of 25(40.0%)LSBE lesions and 5 of 86(5.8%)SSBE lesions. Regarding location, an upper- right location was observed in 9 of 25(36.0%)LSBE lesions and 63 of 86(73.3%)SSBE lesions. SSBE lesions were predominantly elevated, erythematous, and located in the upper-right region, whereas approximately 40% of LSBE lesions were located in the right-upper region and were more likely to accompanied by type IIb or IIb lesions.
