摘　　要：目的 探讨超声内镜联合超声微探头对早期食管浅表癌浸润深度和淋巴结转移的判断及其临床意义。方法 联合应用超声内镜和超声微探头对121例共124处早期浅表型食管癌病灶行临床分期，并与术后及黏膜切除后病理分期相比较。结果 内镜超声检查对早期食管癌术前T分期总的准确率为82．3％（102／124）。本组早期食管癌淋巴结总的转移率为5．0％（6／121），其中原位癌无一例淋巴结转移，黏膜内癌淋巴结转移率为1．3％（1／78），黏膜下癌淋巴结转移率为11．6％（5／43）。结论 联合使用超声内镜及超声微探头对早期食管癌可以进行准确的分期，可以指导早期食管癌治疗策略的选择。Objective To assess the clinical value of endoscopic uhrasonography（EUS） combined with the mini-probe endoscopic uhrasonography （MPUS） in determing tumor invasion depth and lymph node metastases of early superficial esophageal cancer. Methods One hundred and twenty-four superficial esophageal cancer lesions of 121 patients were staged by EUS combined with MPUS, and the results were finally compared with pathological findings of surgical specimens or samples obtained by mucosal resection. Results The diagnostic accuracy of EUS in T staging of superficial esophageal cancer was 82. 3% （102/124）. The total ratio of lymph node metastases was 5.0% （6/121）, with no node metastases in carcinoma in situ, 1.3% （1/28） in mucosal carcinoma, 11.6% （5/43） in submucosal carcinoma. Conclusion EUS combined with MPUS is accurate in staging of the superficial carcinoma, which can help the choice of therapeutic strategies.
