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 value of high frequency small probe endoscopic ultrasonography (UMP) and multislice spiral CT (MSCT) in the preoperative T stage of rectal cancer. Methods: Forty-eight patients with rectal cancer underwent UMP and MSCT before operation and were compared with postoperative pathology. Results: The accuracies of T stage and UMP were 81.25% and 83.33% respectively. The diagnostic accuracy rates of UMP and MSCT for early rectal cancer were 88.89% and 77.78% respectively; the diagnostic accuracy rate of advanced rectal cancer was 79.49% and 84.62% respectively. There was no significant difference between the two groups (P> 0.05). Conclusion: UMP is of great value in the diagnosis of early rectal cancer. Therefore, the search for superficial lesions should be preferred endoscopic UMP.
