摘要
对７３例胃癌患者进行术前超声内镜（ＥＵＳ）检查，结果显示：胃癌的ＥＵＳ影像表现为不规则的低回声肿块，伴部分或全部管壁结构的破坏。ＥＵＳＴ分期与手术病理诊断的符合率为８４．９％，其中对Ｔ１至Ｔ４各期判断正确率分别为１００％、８３．３％、７９．３％和８８．９％。对胃周浸润范围的判断准确率为７７．８％。对肿大淋巴结的显示率达８８．９％。对Ｎ分期诊断准确率为７８．１％，其中Ｎ０、Ｎ１、Ｎ２分期的准确率分别为８７．５％、７３．１％和６６．７％。由于穿透深度的限制，ＥＵＳ评价远处转移（Ｍ分期）的能力有限。
73 patients with gastric carcinomas were examined preoperatively by endoscopic ultrasonography. The results showed that gastric carcinomas were imaged as an irregular hypoechoic mass with partial or total destruction of the normal wall architecture depending on the depth of the tumor invasion. In concordant with the postoperative pathological examinations, the overall accuracy rate of tstaging by EUS was 84.9% and were 100%、 83.3%、 79.3% and 88.9% respectively in T 1, T 2, T 3 and T 4. The coincidence of diagnosis of perigastric infiltration with that of surgical pathology was 77.8%. The display rate of the enlarged lymph node was 88.9%. For the detection of regional lymph node metastases, EUS was accurate in 78.1%, the accurate classifications for N 0, N 1 and N 2 staging were 87.5% , 73.1% and 66.7%, respectively. Due to its limited depth of penetration, the evaluation of distant metastasis (M staging) with EUS is limited.
