【摘要】 目的 评估三维肛管直肠腔内彩色多普勒(3D-ERUS)检查对肛管直肠癌术前诊断及TN分期的应用价值。方法 对78例肛管直肠癌患者于手术前2周内行3D-ERUS、盆腔MRI检查,并以术后的病理检查结果作为金标准,对3D-ERUS检查诊断率进行评估,同时对肿瘤浸润深度(T分期)和局部淋巴结转移(N分期)进行分期判断。结果 3D-ERUS对肛管直肠癌术前诊断符合率100%;其判断直肠癌T分期的准确率为87.18%,盆腔MRI为73.08%,两者比较差异有统计学意义(χ~2=4.871,P<0.05)。3D-ERUS判断直肠癌N分期的准确率为80.77%,盆腔MRI为78.21%,两者比较差异无统计学意义(χ~2=0.157,P>0.05)。结论 3D-ERUS诊断直肠癌及TN分期的准确率高,具有很高的临床应用价值。

【Abstract】 Objective To evaluate the 3 D-ERUS used in preoperative diagnosis and TN stage of anal canal rectal cancer.Method 78 cases of anal canal rectal cancer were taken 3 D-ERUS,cavitas pelvis MRI two weeks before surgery.The diagnose ratio of 3 D-ERUS were evaluated refer to the gold standard:pathologic diagnosis after surgery.Definite the stage of tumor infiltrating(T-stage) and partial nodular transfer(N-stage).Results The preoperative diagnosis ratio of canal rectal cancer was 100% diagnosed by 3 D-ERUS.And the accurate of T-stage was 87.180%,significant compared to cavitas pelvis MRI which was 73.08%(χ~2=4.871,P<0.05).The accurate of N-stage diagnosed by 3 D-ERUS was 80.77%,non-significant compared to cavitas pelvis MRI which was 78.21%(χ~2=0.157,P>0.05).Conclusion The accurate ratio of T-stage and N-stage of canal rectal cancer diagnosed by 3 D-ERUS is high.It has a value to clinical application.
