 In the diagnosis of the depth invasion of ten cases with early gastric cancer, the rate of the diagnostic accuracy was 60% in the x-ray and endoscopic examinations. While, the ratio of the diagnostic accuracy was 70% in the endoscopic ultrasonography. There were two reasons in the wrong diagnosis of the endoscopic ultrasonography. One was the appearance of a ghost echo in a case of superficial type (type Ⅱa) and the other was the existence of fibrosis in a case of depressed type (type Ⅱc+Ⅲ). It was showed in a case of type Ⅱa+Ⅱc that the submucosal layer was depressed and deviated strongly by cancer. It was suggested that a case of flat type ( Ⅱb ) could be visualized as a thickened mucosal layer.
