直肠腔内超声在低位直肠癌术前分期的作用

EFFECT OF ENDOLUMINAL ULTRASOUND IN PREOPERATIVE STAGING OF THE LOWER LEVEL RECTAL CARCINOMA

目的 :探讨直肠腔内超声对低位直肠癌术前分期的作用。方法 :对 5 1例直肠癌病人术前作CT、直肠腔内超声检查并作出术前分期 ,分别与术后病理分期进行对比。结果 :直肠腔内超声对低位直肠癌术前分期(Duke’sA ,B ,C)正确性为 84 .8% ,CT为 70 .4 % (P <0 .0 1) ,对Duke’sD为 10 0 % ,对浸润淋巴检出率腔内超声为 72 .3% ,CT为 5 0 % (P <0 .0 1)。结论 :直肠腔内超声对低位直肠癌术前分期有重要价值。

Objective:To evaluate the role of endoluminal ultrasound in preoperative staging of the lower level rectal carcinoma. Methods:Fifty-one cases of lower level rectal carcinoma diagnosed clinically were staged preoperatively by endoluminal ultrasound and CT scan.Results:Compared with postoperative pathologic staging respectively. The accuracy of the preoperative staging of the low level rectal carcinoma by endoluminal ultrasound is superior to that by CT scan ( P <0.01), Conclusion:Endoluminal Ultrasound is of great value for the clinical treatment of the disease.
