摘　　要：目的 探讨内镜超声检查术(EUS)对食管癌术前分期的作用及其临床意义。方法依据UICC1997年分期标准,对61例食管癌患者术前行EUS临床分期,并与术后病理分期相比较。结果术前EUS对T亚组的临床分期较易,其总准确率为86.9％;而N亚组的临床分期较难,其总准确率为52.5％,敏感性和特异性分别为88.9％及23.5％。结论 EUS能较准确的判断食管癌的浸润深度,对N分期的准确性有待于进一步提高。EUS可作为术前治疗方法选择、手术可切除性预测的重要依据。Objective To study preoperatively on TNM staging of esophageal carcinoma by endo-scopes ultrasonography ( EUS). Methods Sixty-one patients with esophageal carcinoma were preoperatively staged by EUS. The results were compared with the postoperative histopathological staging according to the new (1997) TNM classification. Results Clinical staging of T subsets by EUS was reliable with an overall accuracy rate of 86. 9% , while that of N subsets was relatively more difficult with an overall accuracy rate of 52. 5% ; sensitivity and specificity of regional lymph nodal metastases were 88. 9% and 23. 5% respectively. Conclusion EUS is relatively an accurate measure in assessing the depth of tumor infiltration, whereas further efforts are needed to improve the accuracy in N staging. EUS will be helpful in choice of the appropriate therapeutic procedure and predicting the possibility of surgical resection.
