| 目的 探讨直肠腔内超声(TRUS)对直肠癌术前分期诊断的准确性及腔内超声分期与血清癌胚抗原(CEA)的关系。方法 对52例直肠癌患者行TRUS检查并进行术前分期,同时检测血清CEA水平,并与术后病理分期进行对比。结果 TRUS直肠癌术前分期准确率为76.92%,诊断淋巴结转移的准确率为71.15%。术前CEA水平与直肠癌浸润肠壁深度以及淋巴结转移呈密切相关,应用TRUS检查结合术前血清CEA水平使直肠癌术前分期的准确率达88.46%。结论 TRUS对直肠癌术前分期有着较高的准确性,术前血清CEA水平对直肠癌TRUS分期有着重要的参考价值,TRUS检查结合术前血清CEA水平可提高对直肠癌术前分期的准确率。 |

| Objective To explore the accuracy of transrectal ultrasound (TRUS) in preoperative staging of rectal carcinoma and the relationship between TRUS and serum carcinoembryonic antigen (CEA). Methods Fifty-two patients with rectal carcinoma underwent TRUS. Transrectal ultrasonic preoperative staging of rectal carcinoma was performed and compared with pathologic staging. Results The accuracy rate of preoperative staging of rectal carcinoma with TRUS was 76.92%, of lymph node metastasis was 71.15%. Serum CEA level was closely correlated to the invasive degree of the rectal wall and the lymph node metastasis. The accuracy rate of preoperative staging of rectal carcinoma was high to 88.46% when TRUS combined with the serum CEA level. Conclusion TRUS has high diagnostic accuracy rate in preoperative staging of rectal carcinoma and lymph node metastasis. The serum CEA level of preoperative has the reference value in transrectal ultrasonic preoperative staging of rectal carcinoma. It Combined with the serum CEA level, TRUS can raise the diagnostic accuracy rate of preoperative staging of rectal carcinoma. |
