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 investigate the clinical value of transabdominal ultrasonography and multi-slice spiral CT (MSCT) in the preoperative staging of gastric cancer. Methods: Twenty patients with gastric cancer confirmed by gastroscopic biopsy underwent preoperative abdominal ultrasound examination and MSCT examination, and compared with the postoperative pathological examination results. Results: The correct rate of T staging of gastric cancer was 65% (T1 10 0. 0%, T2 37.5%, T310 0. 0%, T4 33.3%) and MSCT 75. 0% T1 10 0 .0%, T2 6 2 .5%, T 387.5%, T4 6 6 .7%). There was no significant difference between the two groups (P> 0.05). The accuracy of transabdominal ultrasonography in staging N-stage gastric cancer was 66.7% (N0 10 0 .0%, N1 33.3%, N2 42.9%), while MSCT was 72.2% (N0 75. 0%, N1 6 6 .7%, N2 71.4%). There was no significant difference between the two groups (P> 0.05). The correct rates of TNM staging of gastric cancer by transabdominal ultrasonography and MSCT were 6 8.4% and 73.7%, respectively, with no significant difference (P> 0.05). Conclusion: Transabdominal ultrasonography and MSCT have high clinical value in preoperative staging of gastric cancer.
