摘　　要：目的探讨多层螺旋CT(MSCT)、超声内镜(EUS)在胃癌术前T分期中的价值。方法对经病理活检证实的55例胃癌患者术前分别行多层螺旋CT、超声内镜检查并与手术病理进行对比分析。结果 MSCT对胃癌术前T1、T2、T3、T4分期的准确率分别为60.0%、54.5%、91.3%、91.7%,总的T分期准确率为80.0%,超声内镜对胃癌术前T1、T2、T3、T4分期的准确率分别为70.0%、63.6%、87.0%、66.7%,总的T分期准确率为76.4%。两者对总的T分期间的差异无统计学意义。结论 MSCT和EUS对胃癌术前T分期均有较高的准确性,为指导临床合理地制订治疗方案和进行预后分析提供了依据。Objective To investigate the accuracy of multi-slice CT（MSCT） and endoscopic ultrasonography（EUS） in the T staging of gastric cancer.Methods 55 patients with gastric cancer were undergone the T staging by MSCT and EUS before operation.The results were strictly compared with surgical pathology.Results The accuracy by MSCT of T1,T2,T3 and T4 staging were 60.0%,54.5%,91.3% and 91.7% respectively.The accuracy of total T staging was 80.0%.The accuracy by EUS of T1,T2,T3 and T4 staging were 70.0%,63.6%,87.0% and 66.7% respectively.The accuracy of total T staging was 76.4%.There was not significant difference of the diagnostic accuracy in total T staging.Conclusion MSCT and EUS can provide high accuracy in preoperative T staging of gastric cancer,and provide the accurate treatment plan and prognosis analysis.
