 We studied about 31 cases of esophagogastric junctional cancer. Barretts cancers were 5 cases originated from SSBE(intramucosal cancer 4 cases, submucosal invasive cancer 1 cases). Esophagogastric junctional cancers were 26 cases(intramucosal cancer 23 cases, Submucosal invasive cancer 3 cases). Histology of all the cases were well differentiated adenocarcinoma. Magnified NBI findings were vascular pattern mainly and pit pattern mainly. Vascular pattern were classified with fine-net wark and oval vascular pattern. Pit pattern was pit and vascular observed into stroma. Vascular pattern and pit pattern with vascular were observed with mixed. These findings of vascular pattern and pit pattern were demonstrated with 3-D reconstruction of serial section of histology.
