 Comparative study regarding with the classifications of depth of invasion of early gastric cancer associated with peptic ulcer or ulcer scar estimated by EUS was performed.

 In mucosal cancer, smooth tapering of the submucosal layer with fan-shaped hypoechoic area was the basic EUS finding. And it was widely accepted.

 In submucosal cancer, on the other hand, various criteria were proposed: irregularity of the tapered submucosal layer, arch shaped narrowing with or without fusion, obscure interruption of the submucosal layer, slight thickening of the gastric wall to inward and outward, etc. were regarded as the sign of submucosal cancer by EUS.

 The diagnostic criteria of the depth of invasion by EUS will be refined by standardization of diagnostic criteria of the submucosal cancer invasion.
