目的探讨CT对结肠癌的诊断价值及CT表现。方法收集2002-2007年经纤维结肠镜或/和手术病理证实为结肠癌的28例患者进行CT回顾性分析。结果CT显示肿瘤部位准确率为100%,CT分期与手术分期符合率为90%,CT可见癌变部位囊壁增厚、僵硬、浆膜面毛糙、肠腔狭窄,肿块较大时其内还可检出小气泡或/和液体,Ⅲ期以上结肠癌尚有邻近器官浸润、淋巴结肿大及肝转移。结论CT在结肠癌的诊断中占有重要地位,它能发现和显示病变,确定病变浸润范围及转移情况,对确定肿瘤术前分期,选择治疗方法及判定预后起着重要作用。
Objective To investigate the diagnostic value and CT appearance of CT on colon cancer. Methods A retrospective analysis of 28 patients with colon cancer confirmed by fibro-colonoscopy and / or surgery from 2002 to 2007 was performed. Results CT showed that the accuracy of the tumor site was 100%, and the coincidence rate of CT staging and surgical staging was 90%. CT showed thickening of the wall of the cancer site, stiffness, serosal surface roughness, Small bubbles and / or liquids were detected. Stage Ⅲ and above colon cancer still had adjacent organ infiltration, lymphadenopathy and liver metastasis. Conclusion CT plays an important role in the diagnosis of colon cancer. It can detect and display the lesion and determine the extent and metastasis of the lesion. It plays an important role in determining the preoperative staging, selecting treatment and prognosis.
