目的评价多层螺旋CT(MSCT)对结直肠癌性肠梗阻肿瘤TNM分期的价值,提高MSCT对结直肠癌性肠梗阻术前的诊断水平和临床应用价值。方法对67例经手术、病理证实为结直肠癌性肠梗阻患者的MSCT术前TNM分期与临床手术和病理结果进行对照。结果MSCT判断原发病灶、淋巴结转移和远处转移的准确率分别为92.54%(62/67)、88.05%(59/67)和100.00%(67/67),与手术病理结果符合率高。结论MSCT对引起梗阻的结直肠癌的TNM分期判断准确性高,对评估肿瘤可切除性及对制订治疗方案具有重要的指导意义。
Objective To evaluate the value of multi-slice spiral CT (MSCT) in TNM staging of colorectal cancer with intestinal obstruction and to improve the preoperative diagnostic value and clinical value of MSCT for colorectal cancer with intestinal obstruction. Methods Sixty-seven patients with colorectal cancer with intestinal obstruction confirmed by surgery and pathology were compared with preoperative MSCT TNM staging and clinical and pathological findings. Results The accuracy of MSCT in determining primary lesion, lymph node metastasis and distant metastasis was 92.54% (62/67), 88.05% (59/67) and 100.00% (67/67), respectively. The accuracy of MSCT was consistent with the surgical pathology findings. Conclusion MSCT has high accuracy for TNM staging of colorectal cancer causing obstruction, which has important guiding significance for assessing tumor resectability and developing treatment plan.
