超声和CT术前诊断结肠癌的价值观察

Preoperative Diagnostic Value of Ultrasound and Ct in Colon Cancer

目的探究术前诊断结肠癌采用超声与CT诊断价值差异。方法回顾性分析中国人民解放军陆军第83集团军医院2016年8月~2019年8月收治103例结肠癌患者相关资料,患者均接受超声与CT检查,随后以病理组织诊断结果作为金标准,判断超声与CT术前检查诊断价值。结果以病理诊断结肠癌定位结果为标准,CT诊断结肠癌定位符合率明显高于超声(99.03%vs91.26%,P<0.05);CT诊断结肠癌浆膜受侵灵敏度、特异度与准确度分别为93.48%、96.49%、95.15%,超声诊断灵敏度、特异度与准确度分别为84.78%、96.49%、91.26%,CT诊断与病理结果一致性显著优于超声诊断(Kappa值=0.902与0.821);超声与CT在诊断肿瘤分期Ⅲ期、Ⅳ期与病理诊断分期结果一致性较好,而两种方式诊断肿瘤分期Ⅲ期、Ⅳ期价值比较,CT诊断一致性更好(Kappa值:Ⅲ期0.892vs0.859;Ⅳ期0.898vs0.853)。结论超声与CT均可用于结肠癌术前诊断中,CT在结肠癌定位诊断、浆膜受侵以及肿瘤分期上诊断价值更好。

Objective To explore differences in preoperative diagnostic value of ultrasound and CT in colon cancer. Methods The relevant data of 103 patients with colon cancer who were admitted to 83 Group Military Hospital of People’s Liberation Army between August 2016 and August 2019 were analyzed retrospectively. All underwent ultrasound and CT examination. Taking diagnosis results of pathological tissues as golden standard, preoperative diagnostic value of ultrasound and CT was determined. Results Taking pathological diagnostic results for colon cancer as standard, coincidence rate of CT was significantly higher than that of ultrasound(99.03% vs 91.26%, P<0.05). The sensitivity, specificity and accuracy of CT and ultrasound for diagnosis of colon cancer serosa invasion were(93.48%, 96.49%, 95.15%) and(84.78%, 96.49%, 91.26%), respectively. The consistency between CT diagnosis and pathological results was significantly better than that between ultrasound diagnosis and pathological results(Kappa values=0.902, 0.821). The consistency between ultrasound, CT and and pathological diagnosis for tumor staging at stage Ⅲ and Ⅳ was good. The diagnostic consistency of CT was better(Kappa value: stage Ⅲ 0.892 vs 0.859. Sage Ⅳ 0.898 vs 0.853). Conclusion Both ultrasound and CT can be applied in preoperative diagnosis of colon cancer. The diagnostic value of CT is higher in terms of localized diagnosis of colon cancer, serosa invasion and tumor staging.
