目的探讨多层螺旋CT扫描检查 应用于临床结肠癌患者中的效果。方法 回顾性分析我院2014年2月-2016年8月240 例经手术组织病理学证实为结肠癌患者临 床病历资料，所有患者术前、术后6个月 分别采用多层螺旋CT实施扫描检查，比 较多层螺旋CT扫描检查准确性，并记录患 者术后复发情况。结果 采用多层螺旋CT 术前检查结肠癌，其中T分期检查准确率 为85.0%，N分期检查准确率为85.0%，M分 期检查准确率为85.0%，与手术组织切片 检查结果相比较，χ2 =(21.43、18.24、 6.66)，P<0.05；术后多层螺旋CT术前 检查结肠癌，其中T分期检查准确率为 85.71%，N分期检查准确率为88.24%，M分 期检查准确率为100.00%，与手术组织切 片检查结果相比较，χ2 =(7.13、9.74、 9.00)，P<0.05。结论 应用多层螺旋CT于 术前检查结肠癌可有助于患者临床病情评 估，从而指导临床治疗；术后通过采用多 层螺旋CT监测则可有利于判断患者复发或 转移情况，为患者预后判断及临床治疗方 案的制定提供参考。

Objective To explore the effect of multi-slice spiral CT scan in patients with clinical colorectal cancer. Methods The clinical data of 240 patients with colon cancer confirmed by surgery and histopathology from February 2014 to August 2016 were retrospectively analyzed., all patients went on multi-slice spiral CT scan before surgery and 6 months after the surgery, compare the accuracy of multi-slice spiral CT scanning and record postoperative recurrence. Results The accuracy rate of T stage examination was 85.0%, the accuracy rate of N staging was 85.0%, the accuracy of M staging was 85.0%. Compared with the results of surgical tissue biopsy,χ2 =(21.43,18.24,6.66), P<0.05; postoperative multi-slice spiral CT scan, the use of multi-slice spiral CT preoperative examination of colon cancer, which T stage examination accuracy rate of 85.71%, N staging accuracy rate of 88.24 %, M stage check accuracy rate of 100.00%, compared with the results of surgical tissue biopsy,χ2 =(7.13,9.74,9.00), P<0.05. Conclusion The use of multi-slice spiral CT in the preoperative examination of colon cancer can help patients with clinical disease assessment, to guide the clinical treatment; postoperative through the use of multi-slice spiral CT monitoring can be helpful to determine the recurrence or metastasis of patients for patients with prognosis and clinical treatment program to provide reference.
