直肠癌术前超声内镜评估TN分期的临床研究

Role of endoscopic ultrasonography in the diagnosis and preoperative staging of rectum carcinoma

目的 评估超声内镜在直肠癌术前TN分期中的作用.方法 57例直肠癌患者于术前行超声内镜检查,并将其TN分期结果与术后病理学检查分期结果比较.结果 超声内镜诊断直肠癌浸润深度的T分期准确率为78.9%（45/57）,诊断局部淋巴结转移的N分期准确率为73.7%（42/57）.结论 超声内镜对诊断直肠癌浸润深度及淋巴结转移情况有较高的准确性,可在术前有效评价大肠癌病理分期,有助于制订合理的治疗方案.

Objective To evaluate the role of endoscopic ultrasonography in the diagnosis and preoperative staging of rectum carcinoma. Methods Fifty-seven patients with rectum carcinoma were performed with preoperative endoscopy and endoscopic ultrasonography. And the staging results of endoscopic ultrasonography were compared to that of postoperative pathological assessment. Result Compared with the pathological staging, the endoscopic ultrasonography staging accuracy rate was 78.9% （45/57）,and lymph node metastasis accuracy rate was 73.7% （42/57）. Conclusion Endoscopic ultrasonography is effective in diagnosing and preoperative staging of rectum carcinoma.
