双体位CT扫描在进展期胃癌分期中的应用

The Role of DBP-CT in the Staging of Advanced Gastric Cancer

目的探讨双体位CT扫描在进展期胃癌分期中的作用。方法选择100例进展期胃癌患者,随机分为单体位组50例和双体位组50例,单体位组单纯行仰卧位CT扫描,双体位组即采用仰卧位与补充体位行CT扫描,口服水作对比剂行CT检查,分别行术前CT分期与手术结果的比较和分析。结果双体位组术前分期的准确性为90.0%,单体位组仅为60.0%,两组间差异有统计学意义(P<0.05)。结论双体位组在对检出病变、确定病变范围方面明显优于单体位组,因此双体位CT扫描有助于提高进展期胃癌CT分期的准确性。

ObjectiveTo explore the role of using the double body position CT（DBP-CT） in the staging of advanced gastric cancer.MethodsTotaly 100 patients with Advanced gastric cancer which were divided into the double postion group（n=50）and the single position group（n=50）,the single position group was given supine position CT scans,the double postion group was given supine position and complement position CT scans,after oral intake water agent,the preoperative CT findings of each group was compared with surgical findings respectively and the accuracy in the CT staging of advanced gastric cancer of each group was estimated.Results The accuracy in the preoperative CT staging of double postion group was 90.0%,and in single position group was 60.0%,there was a singnificant difference（P〈 0.05）.Conclusion Our findings show that the DBP-CT is surperior to the single position group in finding lesion,confineing the range of the tumour,it can improve the diagnostic accuracy in the preoperative staging of advanced gastric cancers significantly.
