 We investigated the findings of magnifying NBI(narrow-band imaging)endoscopy in the diagnosis of depressed epithelial tumors(early gastric cancer and adenoma). Of 121 cases with early differentiated gastric cancers of 10 mm or smaller, 41(34%)showed microvascular pattern(fine-network vessels)and 70(58%)showed corkscrew, whorl-like vascular pattern within the mucosal structure. In 44 cases with undifferentiated adenocarcinoma of 10 mm or smaller, opening of the pit and large-size pit structure was found in 21 cases, of which 18(86%)demonstrated cancer progression only to the proliferation layer. In 5 cases, corkscrew-patterned vessels were seen in the large-size pit and 4 of them were found to have adenocarcinoma invading the whole thickness of the gastric wall or spreading from the proliferation layer to the surface layer. Corkscrew pattern was found in 18 cases, of which 11(61%)were adenocarcinomas involving the whole thickness of the gastric mucosa. We then examined 26 cases in which biopsy revealed depressed adenomas. The final pathological diagnosis was adenoma of moderate atypia in 13 cases and adenoma of high-grade atypia or differentiated adenocarcinoma in the remaining 13 cases. Of these 26 cases, 14(54%)showed network-patterned vessels, making it difficult to differentiate between cancer and adenoma. Structural pattern was found in 12(46%)of 26 cases, and 5 of them showing whole-vascular patterned vessels within the structure were adenocarcinoma or adenoma of high-grade atypia, suggesting that this finding seems useful for differentiating cancer from adenoma.
