超声内镜及CT检查对食管胃结合部腺癌术前TN分期的价值

摘要

Objective To evaluate the clinical application of TN staging system by analyzing its degree of accuracy of the adenocarcinoma of esophagogastric junction (AEG) by endoscopic ultrasonography (EUS) and helical CT.Methods 91 pathologically proven AEG patients with full clinical data who received preoperative EUS and helical CT check and surgical resection ranging from Feb.2007 to Dec.2012 were studied,together with the contrastive analysis of their postoperative pathologic staging.Results The overall accuracy of preoperative T staging and N staging by EUS were 81.3％ and 86.8％,respectively; wheras those by helical CT were 58.2％ and 58.3％,respectively.The difference between two groups had statistical significance.Conclusion Compared with helical CT,EUS has higher degree of accuracy and could be applied to provide guidance on working out rational operation methods.%目的 通过分析超声内镜(EUS)、螺旋CT检查对食管胃结合部腺癌(AEG)术前TN分期的准确性,评价其临床应用价值.方法 2007年2月-2012年12月接受外科手术切除的91例经病理证实且临床资料完整的AEG患者纳入研究,所有研究对象均于术前行EUS及螺旋CT检查,结合术后病理分期进行对比分析.结果 EUS对AEG术前T分期总准确率为81.3％,N分期准确率为86.8％;螺旋CT的TN分期准确率分别为58.2％、58.3％;前者明显高于后者,差异有统计学意义.结论 EUS较CT更能准确地判断AEG的TN分期,有助于指导制订合理的手术方案.
