 36 cases of elevated early gastric cancers and 34 cases of adenomas were examined concerning surface microvascular structure and surface structure using magnified NBI.

 Elevated early gastric cancers showed a fine network surface microvascular structure and surface structure like cobblestone. 36% of cases showed a fine network pattern. 50% cases showed cobblestone-like surface structure and6% of cases showed tubular surface structure. On the other hand, adenoma showed cobblestone-like surface structure (38%), tubular surface structure (29%) and fine network pattern (21%). Cancer with adenoma showed fine network pattern (35%) and cobblestone-like surface structure (50%). The main surface structures are fine network pattern and cobblestone-like surface structure in cancer with adenoma. But fine network pattern was observed in 79% of cancer cases with adenoma as minor findings. Fine network pattern is a finding which is useful in the differential diagnosis adenoma and cancer with adenoma.
