多层螺旋CT、肠腔充盈超声造影单独及联合检查对结肠癌的诊断价值

Diagnostic value of multi-slice spiral CT and intestinal filling contrast-enhanced ultrasound single and combined examinations for colon cancer

目的探讨多层螺旋CT、肠腔充盈超声造影单独及联合检查对结肠癌的诊断价值。方法选取98例结肠癌患者,术前均行多层螺旋CT、肠腔充盈超声造影检查。以病理检查结果为金标准,比较多层螺旋CT、肠腔充盈超声造影单独及联合检查对结肠癌、淋巴结转移及对结肠癌T分期的诊断符合率。结果病理检查结果显示,98例结肠癌患者中淋巴结转移35例。多层螺旋CT、肠腔充盈超声造影联合检查诊断结肠癌的符合率高于二者单独检查,差异有统计学意义(P﹤0.05);多层螺旋CT、肠腔充盈超声造影单独及联合检查诊断结肠癌淋巴结转移的符合率比较,差异无统计学意义(P﹥0.05)。病理检查结果显示,结肠癌T1~2期25例,T3期54例,T4期19例。多层螺旋CT、肠腔充盈超声造影联合检查诊断结肠癌T3、T4期的符合率均高于二者单独检查(P﹤0.05)。结论多层螺旋CT联合肠腔充盈超声造影检查对结肠癌的诊断价值较高。

Objective To explore the diagnostic value of multi-slice spiral CT and intestinal filling contrast-enhanced ultrasound single and combined examinations for colon cancer.Method A total of 98 colon cancer patients who under-went preoperative multi-slice spiral CT and intestinal filling contrast-enhanced ultrasound examination were selected.The pathological examination results were used as the gold standard,the diagnostic accordance rate of multi-slice spiral CT and intestinal filling contrast-enhanced ultrasound single and combined examinations for colon cancer,lymph node metas-tasis,as well as T stage of colon cancer were compared.Result The pathological examination result showed that there were,35 cases of lymph node metastasis in 98 patients with colon cancer.The diagnostic accordance rate of the multi slice spiral CT and intestinal filling contrast-enhanced ultrasound combined examination in diagnosing colon cancer was significantly higher than those of the single examinations,and the differences were statistically significant(P<0.05).There were no significant differences in the diagnostic accordance rate of the multi-slice spiral CT and intestinal filling contrast-enhanced ultrasound single and combined examinations in diagnosing lymph node metastasis of colon cancer(P>0.05).The pathological examination result showed that there were 25 cases of T1-2 stage,54 cases of T3 stage,and 19 cases of T4 stage.The diagnostic accordance rate of multi-slice spiral CT and intestinal filling contrast-enhanced ultrasound combined examination in diagnosing T3 stage and T4 stage of colon cancer were higher than those of the single examina-tions,and the differences were statistically significant(P<0.05).Conclusion The multi-slice spiral CT and intestinal fill-ing contrast-enhanced ultrasound combined examination has a high diagnostic value for colon cancer.
