摘　　要：目的探讨CT仿真结肠镜(CTVC)对于大肠癌术前定性和定位的临床诊断的价值。方法回顾性分析51例大肠癌患者术前行CTVC和结肠镜检查并手术治疗的影像资料和临床资料。结果全组51例大肠癌患者均经手术和病理证实。术中证实CTVC的检出率为100%,结肠镜检查的检出率为92.0%。CTVC定位准确(100%),结肠镜检查定位符合率为93.6%。CTVC术前临床分期准确率是9 4.1%。结论 CTVC是一种无创的检查方法,可判断肠外浸润转移范围、在重度肠腔狭窄时观察近端肠段,综合分析肿瘤的性质和确定肿瘤的部位,并与结肠镜检查形成互补,对大肠癌的临床分期和选择手术方案具有重要的意义。Objective To investigate the clinical diagnostic value of CT virtual colonoscopy（CTVC） in preoperative determination of the nature and localization of colorectal cancer. Methods The imaging and clinical data of 51 patients with colorectal cancer undergoing preoperative CTVC and colonoscopic examination as well as surgical treatment were retrospectively analyzed. Results The whole group of 51 patients were confirmed to have colorectal cancer by surgical biopsy and pathological examination.After surgical confirmation,the detection rate of CTVC and colonoscopy was 100% and 92.0%,respectively.Localization accuracy of CTVC was 100%,while that of colonoscopy was 93.6%.The coincidence rate of clinical staging by preoperative CTVC was 94.1%. Conclusions CTVC is a non-invasive method that can determine the extent of extra-intestinal invasion and metastasis,inspect the proximal bowel wall in cases with severe luminal stricture and comprehensively define the nature and position of the tumor.Furthermore,it is complementary to colonoscopy,and is of great importance in clinical staging of colorectal cancer and selection of the operative procedure.
