直肠腔内超声检查在低位直肠癌保肛手术中的临床价值

Clinical value of endorectal ultrasonography in Anus preserving operation for low rectal carcinoma

目的探讨经直肠超声(endorectalultrasonography,ERUS)在低位直肠癌保肛手术中的临床价值。方法术前ERUS检查200例低位直肠癌患者并定位和分期,分别与术中肿瘤位置、分期及术后病理分期进行对比。结果与病理分期对比,术前ERUS总符合率达85%(170/200)。预测低位直肠癌保肛手术的总体正确率为90%(180/200)。结论 ERUS对低位直肠癌术前分期及保肛有重要价值。

Objective To investigate the clinical value of endorectal ultrasonography（ERUS）in anus preserving operation for low rectal carcinoma.Methods Two hundred cases of low rectal carcinoma were preoperatively staged and localized by ERUS and compared with location during operation and staging by pathology.Results Compared with postoperative pathologic staging,the accuracy of preoperative staging of the low rectal carcinoma by ERUS was 85%.The accuracy of prediction of operation modus was 90%（180/200）overall.Conclusion ERUS has important clinical value in the low rectal carcinoma operation.
