摘　　要：目的 评价超声内镜、螺旋CT检查对食管癌术前TN分期的价值。方法 回顾性总结术前EUS、CT判断87例食管癌的分期资料，并与术后病理分期对照。患者均未行化、放疗。环扫超声内镜进行操作，5例轻度狭窄病例扩张后再予EUS分期。结果 EUST分期总准确率为85．1％，CT无法区分T1、T2。对于N分期，EUS判断探及范围内淋巴结转移的灵敏度为85．0％，高于CT扫描的60．8％；CT探查纵隔淋巴结较EUS全面。EUS与CT联合判断T分期的准确率为85．1％，N分期的准确率为90．8％。结论 EUS判断肿瘤浸润深度准确性高，EUS联合CT可进行更为全面准确的TNM分期。Objective To retrospectively evaluate the accuracy of endoscopic uhrasonography （EUS） and CT in preoperative tumor, and nodal metastasis （TN） staging of esophageal carcinoma. Methods TN stages of 87 cases diagnosed with preoperative EUS and CT were compared with postoperative pathological results. No patient underwent radiotherapy or chemotheraphy . The radial echoendoscope was used, and balloon dilation was required in 5 cases with stricture. Results The total accuracy of T staging with EUS was 85.1%. CT could not differentiate T1 from T2. The sensitivity of EUS for N staging was 85.0%, higher than that of CT（60. 8% ）. However, some lymph nodes which were not detected by EUS could be revealed by CT. Accuracy of EUS plus CT in T staging is 85.1% , and that in N staging is 90. 8%. Conclusion EUS is the most accurate measure in assessing the depth of tumor invasion, whereas the combination of EUS and CT is capable of an overall evaluation for TNM staging.
