In the diagnosis of the infiltrating depth of thirty four cases with gastric cancer, in which twenty two cases were early cancer and fourteen cases advanced cancer, the rate of the diagnostic accuracy by EUS was eighty eight % in the differentiation between early cancer and advanced cancer. While, in distinction of cancer spreading into the mucosa, the submucosa, the muscularis propria and over the subserosa, diagnostic accuracy was sixty four % in early cancer and seventy five % in advanced cancer. There were two reasons mainly in the wrong diagnosis of EUS. One was the existence of fibrosis in cases of the depressed type of early cancer and the other was the dissemination of the cancer cells extending into the deeper tissues, which could be detected only by histological examinations.
在对34例胃癌患者浸润深度的诊断中，其中22例为早期癌，14例为进展期癌，EUS鉴别早期癌与进展期癌的诊断准确率为88%。而在区分癌组织浸润至黏膜、黏膜下层、固有肌层及浆膜下层时，早期癌的诊断准确率为64%，进展期癌为75%。EUS误诊主要有两个原因。一是凹陷型早期癌病例中存在纤维化，另一个是癌细胞扩散至更深层组织，这只能通过组织学检查才能发现。
