抄録 Aims: This study aimed to clarify the findings for early detection of superficial Barrett's esophageal cancer by elucidating its endoscopic characteristics. Materials and Methods: The subjects comprised 58 superficial Barrett's esophageal cancers in 54 cases endoscopically or surgically resected at our hospital. The patients were 48 males and 6 females at the average age of 65.6 years. Their background, macroscopic types, color, location, and pathology were examined. Results: There were 10 long segment Barrett's esophagus (LSBE) and 44 short segment Barrett's esophagus (SSBE) cases. Macroscopically, there were 40 elevated-type (69%) and 18 depressed-type (31%) lesions. Redness was present in 53 (91%) and absent in 5 lesions (9%) and all reddish lesions were observed as a brownish area by NBI with a low magnification. In terms of location, 53 (91%) and 5 lesions (9%) were located on the right and left wall of the esophagus, respectively. With regard to the spatial relationship with the squamocolumnar junction (SCJ), 47 lesions (81%) were located at the oral side of Barrett's epithelium. In total, 35 cases were treated endoscopically (5 of them were additionally resected surgically for submucosal [SM] invasion), while 19 were treated surgically. All lesions were differentiated adenocarcinoma histologically. Conclusions: For early detection of superficial Barrett's esophageal cancer, attention should be paid to a reddish elevated lesion localized on the right wall at the oral side of Barrett's esophagus.
