目的 判断术前多层螺旋CT(MSCT)结肠充气法扫描诊断结肠癌TN分期及结肠系膜侵犯情况与手术病理的符合情况,探讨MSCT的临床价值.方法 收集经手术病理确诊的结肠癌患者96例.术前患者均行结肠充气法MSCT常规及动态增强扫描,获得平扫、动静脉期CT图像、曲面重建(CPR)及多平面重建(MPR)图像.对肿瘤进行术前MSCT的TN分期,并评估结肠系膜的侵犯程度,与术后临床TN分期和结肠系膜的侵犯程度比较.评价两种诊断结果间的一致性.结果 96例结肠癌患者均获得良好的MSCT图像,并经手术病理证实.MSCT预测结肠癌TN分期及其系膜侵犯程度的准确率、灵敏度、特异度、假阴性率、假阳性率方面与临床分期结果有良好的一致性(均Kappa＞ 0.69,均P＜ 0.01).结论 结肠充气法MSCT能够较好地揭示结肠癌的术前≤T2、T3、T4分期、N分期和结肠周围系膜的侵犯等情况,是制定临床治疗方案前重要的无创性检查方法.
目的 判斷術前多層螺鏇CT(MSCT)結腸充氣法掃描診斷結腸癌TN分期及結腸繫膜侵犯情況與手術病理的符閤情況,探討MSCT的臨床價值.方法 收集經手術病理確診的結腸癌患者96例.術前患者均行結腸充氣法MSCT常規及動態增彊掃描,穫得平掃、動靜脈期CT圖像、麯麵重建(CPR)及多平麵重建(MPR)圖像.對腫瘤進行術前MSCT的TN分期,併評估結腸繫膜的侵犯程度,與術後臨床TN分期和結腸繫膜的侵犯程度比較.評價兩種診斷結果間的一緻性.結果 96例結腸癌患者均穫得良好的MSCT圖像,併經手術病理證實.MSCT預測結腸癌TN分期及其繫膜侵犯程度的準確率、靈敏度、特異度、假陰性率、假暘性率方麵與臨床分期結果有良好的一緻性(均Kappa＞ 0.69,均P＜ 0.01).結論 結腸充氣法MSCT能夠較好地揭示結腸癌的術前≤T2、T3、T4分期、N分期和結腸週圍繫膜的侵犯等情況,是製定臨床治療方案前重要的無創性檢查方法.

Objective To evaluate the accuracy of multi-slice spiral computed tomography (MSCT) in preoperative TN staging and in judging surrounding mesenteric invasion.Methods 96 cases of patients with colon carcinoma which was historically confirmed were collected.Common practice scanning with inflation and dynamic contrast-enhancement scan were performed preoperatively and the images of plain scan,venous phase and arterial phase of contrast enhancement including multi-planar and curved planar reconstruction were obtained.TN staging and evaluation of surrounding mesenteric infiltration were made by MSCT.Surgical findings and pathological results were compared with MSCT diagnosis.The accuracy,sensitivity,specificity,false negative rate,false positive rate and consistency analysis between them were compared.Results The accuracy,sensitivity,speciality rate,false negative rate and false positive rate of TN staging of colon cancer,as well as mesenteric infiltration determined with MSCT were consistent with the clinical and historical results (Kappa ＞ 0.69,P ＜ 0.01),meaning good consistency.Conclusion MSCT for colon inflation is a useful method for revealing T staging (≤T2-T4),N staging and mesenteric infiltration of colon carcinoma preoperatively.It is also an important noninvasive method to provide surgeons with valuable information for making treatment plan of the tumor.
