食管双重对比造影、螺旋CT在食管癌T分期中的对比应用

Applications of double-contrast esophagram and spiral CT in T staging of esophageal cancer

目的:探讨食管双重对比造影、螺旋CT在食管癌T分期中的应用价值。方法:49例食管癌住院病人行食管双重对比造影检查及螺旋CT检查,所有影像学发现与术后病理进行对照以确定病变在食管壁的侵犯深度。结果:对于总的食管癌T分期,螺旋CT检查(73.5%)较食管双重对比造影检查(59.2%)有更高的准确率(P<0.05)。食管双重对比造影T1分期准确率为80%,而螺旋CT无法区别T1、T2期。螺旋CTT4分期准确率(87.5%)高于食管双重对比造影(25.0%)(P<0.05)。结论:食管双重对比造影对T1期食管癌的诊断较螺旋CT更有价值,而螺旋CT能更好显示T4期食管癌。

Objective： To compare the accuracy between double-contrast esophagram and spiral CT in diagnosis on T staging of esophageal cancer. Methods： 49 cases of esophageal cancer patients were examined by double-contrast esophagram and spiral CT. All patients subsequently underwent surgery. Results of double-contrast esophagram and spiral CT were compared with histologic staging of tumor invasion depth. Resuits： For T staging, spiral CT accuracy was higher than that of double-contrast esophagram （73.5% and 59.2%, respectively, P 〈0.05）. The accuracy of double-contrast esophagram in T1 staging were 80.0%, and spiral CT can not distinguish between T1 and T2. The accuracy of spiral CT in T4 staging was higher than that of double-contrast esophagram （87.5% and 25.0%, respectively, P 〈0.05）. Conclusion： Double contrast esophagram is more accurate than spiral CT for T1 staging and spiral CT is significantly better than double-contrast esophagram for T4 staging.
