 We investigated submucosal invasive early gastric undifferentiated adenocarcinoma using findings of CV(calibar variation)with NBI. Among operated cases 77 cases and ESD cases 136cases were studied. Operated cases, 38 cases were intramucosal and 39 cases were submucosal cancers. Twenty-tow cases were diagnosed by ordinary endoscopic findings(55%). Among ESD cases, 116cases were intramucosal lesions and 20 were submucosal invasive cases. CV was defined in 29/39(74%)in operated cases and 16/20(80%)in ESD cases of submucosal invasive cancer. Submucosal invasive cancer(11 cases)with CV were detected through IRI with ICG. In 6 cases(6/11 : 55%)pooling was detected with IRI. Concerning immunohistological study, normally, we could not define SMA positive vessels on the surface of the gastric mucosa. But we were able to define SMA positive large vessels in all 11 cases. CV revealed SMA positive vessels on the gastric surface. Using IRI, pooling vessels revealed tumor vessels.
