经腹超声检查和多层螺旋CT对胃癌术前分期的初步研究

A Preliminary Study of Transabdominal Ultrasonography and Multi-slice Spiral CT in the Preoperative Staging of Gastric Carcinoma.

目的 :探讨经腹超声检查和多层螺旋CT(multi-slicespiralCT ,MSCT)在胃癌术前分期中的临床应用价值。方法 :对 2 0例经胃镜活检证实的胃癌病人术前行经腹超声检查和MSCT检查 ,并与术后病理检查结果对照。结果 :经腹超声检查对胃癌T分期的正确率为 6 5 % (其中T1 10 0 .0 % ,T2 37.5 % ,T310 0 .0 % ,T4 33.3% ) ,而MSCT为 75 .0 %(其中T1 10 0 .0 % ,T2 6 2 .5 % ,T387.5 % ,T4 6 6 .7% ) ,两者间差异无显著性 (P >0 .0 5 )。经腹超声检查对胃癌N分期的正确率为 6 6 .7% (其中N0 10 0 .0 % ,N1 33.3% ,N2 4 2 .9% ) ,而MSCT为 72 .2 % (其中N0 75 .0 % ,N1 6 6 .7% ,N2 71.4 % ) ,两者间差异无显著性 (P >0 .0 5 )。经腹超声检查和MSCT对胃癌TNM分期的正确率分别为 6 8.4 %和 73.7% ,两者间差异无显著性 (P >0 .0 5 )。结论 :经腹超声检查和MSCT对胃癌术前分期均具有较高的临床价值。

Objective: To explore the clinical value of transabdominal ultrasonography and multi-slice spiral CT(MSCT) in the preoperative staging of gastric carcinoma. Methods: Transabdominal ultrasonography and MSCT were performed in 20 patients with gastric carcinoma confirmed by means of biopsy, and the results were compared with postoperative pathologic findings. Results: The accuracy rate of transabdominal ultrasonography in determining the T stage of gastric carcinoma was 65%(T 1 100%, T 2 37.5%, T 3 100%, T 4 33.3%),and the accuracy rate of MSCT was 75%(T 1 100%, T 2 62.5%, T 3 87.5%, T 4 66.7%), there was no significant difference(P>0.05) between them. The accuracy rate of transabdominal ultrasonography in determining the N staging of gastric carcinoma was 66.7%(N 0 100%, N 1 33.3%, N 2 42.9%), and the accuracy of MSCT was 72.2%(N 0 75%, N 1 66.7%, N 2 71.4%), there was no significant difference(P>0.05) between them. The accuracy rate of TNM staging by transabdominal ultrasonography and MSCT was 68.4% and 73.7% respectively. There was no significant difference(P>0.05) between them. Conclusions: The clinical value of transabdominal ultrasonography and MSCT in the preoperative staging of gastric carcinoma was relatively high.
