CT与MRI术前诊断结肠癌及评价术后复发的价值

Value of CT and MRI in Preoperative Diagnosis and Postoperative Recurrence of Colon Cancer

目的分析CT与MRI术前诊断结肠癌及评价术后复发的价值。方法选取2018年1月-2020年1月我院188例疑似结肠癌患者作为研究对象,均行CT与MRI检查,以病理诊断结果为准,分析CT、MRI诊断价值;并对确认结肠癌且经手术治疗后患者随访1年,分析CT、MRI评价术后复发的应用价值。结果188例疑似结肠癌患者中,术后病理诊断确诊152例,36例为良性病变。CT检查诊断结肠癌149例,MRI检查诊断结肠癌150例,CT与MRI术前诊断灵敏度、特异度以及准确率比较,差异无统计学意义(P>0.05)。152例结肠癌患者经手术治疗后并随访1年,经穿刺活检病理诊断发现28例复发,CT检查发现33例复发,MRI检查发现31例复发,CT与MRI术后复发灵敏度、特异度以及准确率比较,差异无统计学意义(P>0.05)。结论CT与MRI在术前诊断结肠癌及评价术后复发中均具有较高的应用价值,两者在检测中的准确性相似,且具有操作简单、无创、可重复等优势,患者接受能力较强,相比之下CT对肠道准备的要求较低,而MRI的图像分辨率较高,临床中应根据实际情况灵活选择。

Objective To analyze the value of CT and MRI in preoperative diagnosis of colon cancer and evaluation of postoperative recurrence.Methods A total of 188 patients with suspected colon cancer in our hospital from January 2018 to January 2020 were selected as the research objects and underwent CT and MRI examination.The diagnostic value of CT and MRI was analyzed based on the pathological diagnosis results.The patients who confirmed colon cancer and received surgical treatment were followed up for 1 year to analyze the application value of CT and MRI in evaluating postoperative recurrence.Results Among 188 patients with suspected colon cancer,152 cases were confirmed by postoperative pathological diagnosis,and 36 cases were benign lesions.There were 149 cases of colon cancer diagnosed by CT examination and 150 cases of colon cancer diagnosed by MRI examination.There was no significant difference in the sensitivity,specificity and accuracy of preoperative diagnosis between CT and MRI(P>0.05).One hundred and fifty-two patients with colon cancer were followed up for 1 year after surgical treatment.Twenty-eight patients were found to have recurrence by pathological diagnosis of puncture biopsy,33 patients were found to have recurrence by CT examination,and 31 patients were found to have recurrence by MRI examination.There was no significant difference in the sensitivity,specificity and accuracy of recurrence between CT and MRI(P>0.05).Conclusion CT and MRI have high application value in preoperative diagnosis of colon cancer and evaluation of postoperative recurrence.The accuracy of the two methods in detection is similar,and they have the advantages of simple operation,non-invasive and repeatable,and the patient's acceptance ability is strong.In contrast,CT has lower requirements for bowel preparation,and MRI has higher image resolution,which should be flexibly selected according to the actual situation.
