摘　　要：目的:探讨高频小探头内镜超声(UMP)和多层螺旋CT(MSCT)在直肠癌术前T分期中的临床应用价值。方法:对48例直肠癌患者术前分别行UMP和MSCT检查,并与手术后病理进行对照。结果:UMP和MSCT对T分期判断准确率分别为81.25%和83.33%。UMP和MSCT对早期直肠癌的诊断准确率分别为88.89%和77.78%;进展期直肠癌的诊断准确率则是79.49%和84.62%。两者差异无统计学意义,P>0.05。结论:UMP对早期直肠癌诊断具有重要价值。因此,对于内镜下查找浅表病灶应首选UMP。OBJECTIVE： To investigate the clinical significance of high frequency endoscopic ultrasound mini probe（UMP） in the preoperative T-staging of rectal cancers.METHODS： Both UMP and MSCT were performed in 48 patients with pathologically proven rectal cancers,and the results of UMP were compared with surgical pathologic findings.RESULTS：The accuracy of UMP and MSCT in T staging was 81.25% and 83.33% respectively.The accuracy of UMP and MSCT for early rectal cancers was 88.89% and 77.78% respectively.The accuracy of UMP and MSCT for advanced rectal cancers was 79.49% and 84.62% respectively,and there was no statistical difference（P0.05）.CONCLUSIONS：UMP appears to have a substantial diagnostic value for early stage rectal cancer.It is the approach of choice for superficial lesions.
