老年人进展期结肠癌彩色多普勒超声与电子结肠镜检查的对比研究

目的 探讨彩色多普勒超声榆查在老年人进展期结肠癌诊断中的价值及其与电子结肠镜检查的比较. 方法经彩色多普勒超声对69例老年结肠癌患者进行诊断,并将诊断结果与电子结肠镜检查及手术病理检查结果进行对比研究. 结果与手术病理诊断及定位诊断比较,彩色多普勒超声对老年人结肠癌定性诊断符合率为95.6%(66/69),电子结肠镜为91.3%(63/69),2种检查定性诊断符合率的差异无统计学意义(精确概率P>0.05);彩色多普勒超声对老年人结肠癌定位诊断符合率为91.3%(63/69),电子结肠镜为94.2%(65/69),2种检查定位诊断符合率的差异无统计学意义(χ~2=0.431,P>0.05).彩色多普勒超卢对患者瘤体内部小同程度的血流信号均可探出,其检出率为100%,对腹腔淋巴结转移、肝转移、周围组织侵犯及远端结肠转移诊断的符合率分别为87.5%、100%、84.6%及100%. 结论彩色多普勒超声对老年人结肠癌的诊断具有较高的应用价值,可作为老年人进展期结肠癌诊断的一项无创性检查方法.彩色多普勒超声与电子结肠镜检查相互结合,对老年人结肠癌的诊治可提供更可靠的依据.

Comparative study on color Doppler ultrasound and electronic colonoscopy for diagnostic value in elderly patients with advanced colon cancer

Objective To explore the diagnostic values of color Doppler flow imaging (CDFI) for the elderly patients with advanced colon cancer and to compare it with electronic colonoscopy (EC). Methods A total of 69 elderly patients were diagnosed as colon cancer using CDFI, and the results of CDFI were compared with EC results and surgical pathology. Results Compared with surgical pathology, the diagnosis accordance rate of CDFI for colon cancer was 95. 6% (66/69), while EC was 91.3%(63/69)(P > 0. 05). The location diagnosis rate of CDFI was 91. 3% (63/69) , while EC was 94. 2%(65/69)(χ~2 =0. 431,P>0. 05). At the same time, the detection rate of the different levels of blood flow signals within tumor by CDFI was 100%. And the diagnosis accordance rates of CDFI for abdominal lymph node metastasis, liver metastasis, damage to surrounding tissue and distal metastasis were 87.5%, 100%, 84.6% and 100%, respectively. Conclusions CDFI has a high value for the diagnosis of colon cancer in elderly patients, and it could be used as a screening method. The application of CDFI and EC for colon cancer in the elderly is reliable.
