360度直肠腔内超声与多层螺旋CT对直肠癌TN分期的对比研究

目的比较360度直肠腔内超声与多层螺旋CT(MSCT)对直肠癌TN分期的诊断价值。方法将我院75例直肠癌患者作为研究对象,均进行360度直肠腔内超声与MSCT检查,并以术后病理结果为标准,分析比较360度直肠腔内超声与MSCT对直肠癌术前T、N分期的诊断效能。结果术后病理结果显示,75例患者T1期、T2期、T3期及T4期分别为7例、10例、49例和9例;N0期、N1期及N2期分别为43例、20例、12例。360度直肠腔内超声、MSCT对直肠癌术前T分期诊断总准确度分别为80.00%、76.00%,与病理T分期诊断一致性分析显示Kappa值分别为0.820、0.788(均P<0.05)。360度直肠腔内超声、MSCT对直肠癌术前N分期诊断总准确度分别为77.33%、80.00%,与病理N分期诊断一致性分析显示Kappa值分别为0.773、0.800(均P<0.05)。结论360度直肠腔内超声对直肠癌术前T分期诊断效能稍优于MSCT,对直肠癌术前N分期诊断效能稍低于MSCT。

Comparative Study 9f 360-degree Endorectal Ultrasound and Multi-slice Spiral CT in the TN Staging of Rectal Cancer

Objective To compare the diagnostic value of 360-degree endorectal ultrasound and multi-slice spiral CT(MSCT)on TN staging of rectal cancer.Methods 75 patients with rectal cancer in our hospital were selected for the study.All patients were given 360-degree endorectal ultrasound and MSCT examination.The postoperative pathological results were used as the standards to analyze and compare the diagnostic efficacy of 360-degree endorectal ultrasound and MSCT on preoperative T staging and N staging of rectal cancer.Results Postoperative pathological results showed that among 75 patients,there were 7 cases,10 cases,49 cases and 9 cases in T1 stage,T2 stage,T3 stage and T4 stage respectively,and there were 43 cases,20 cases and 12 cases in N0 stage,N1 stage and N2 stage respectively.The total accuracies of 360-degree endorectal ultrasound and MSCT on preoperative T staging of rectal cancer were 80.00%and 76.00%respectively,and the consistency analysis with pathological T staging showed that Kappa values were 0.820 and 0.788 respectively(all P<0.05).The total accuracies of 360-degree endorectal ultrasound and MSCT on preoperative N staging of rectal cancer were 77.33%and 80.00%respectively,and the consistency analysis with pathological N staging showed that Kappa values were 0.773 and 0.800 respectively(all P<0.05).Conclusion 360-degree endorectal ultrasound has better diagnostic efficacy than MSCT in the diagnosis of preoperative T staging of rectal cancer,and its diagnostic efficacy is slightly lower than that of MSCT in the preoperative N staging of rectal cancer.
