摘要
目的通过分析超声内镜对低位直肠癌术前TN分期的准确性,探讨其对低位直肠癌保肛手术选择的指导作用。方法对87例手术切除的低位直肠癌患者术前行超声内镜检查,术前分期与术后病理对照,以评价EUS对直肠癌术前分期的准确性。结果超声内镜对低位直肠癌T1分期符合率100%,T2分期符合率96.0%,T3分期符合率85.7%,T4分期符合100%;超声内镜的T分期结果与手术病理分期结果一致性好(Kappa=0.903,P<0.05);N分期中N0分期符合率87.0%,N1分期符合率78.6%,N3分期符合率100%。超声内镜的N分期结果与手术病理分期结果一致性较好(Kappa=0.768,P<0.05)。结论超声内镜术前评价低位直肠癌临床分期具有一定的优越性,尤其对低位直肠癌侵犯深度及淋巴结转移的判断有较高的准确率。
Objective To investigate the guidance of the endoscopic ultrasonography for the surgery selection of patients with low rectal cancerthrough analyzing the accuracy of endoscopic ultrasonography in preoperative TN staging.Methods Eighty-seven cases with low rectal cancer received preoperative endoscopic ultrasonography examination,the preoperative staging and the postoperative pathologic comparison.The EUS accuracy of preoperative staging of rectal cancer was evaluated.Results The preoperative staging with endoscopic ultrasonography for patients with low rectal cancer,100% in T1 stage,96.0% in T2 stage,85.7% in T3 stage,and 100% in T4 stage.The preoperative staging and the postoperative pathologic comparison in T stage were consistent(Kappa=0.903,P<0.05).The preoperative staging with endoscopic ultrasonography for patients with low rectal cancer,87.0% in N0 stage,78.6% in N1 stage,and 100%in N2.The preoperative and the postoperative pathologic comparisons in N stage were consistent(Kappa=0.768,P<0.05).ConclusionThe endoscopic ultrasonography had a certain advantage in the clinical preoperative evaluation for patients with low rectal cancer,especially for invasion depth and the judgment of lymph node metastasis,with a higher accuracy.
