CT检查对术前结肠癌及术后结肠癌复发患者的临床诊断价值及准确率分析

Analysis of clinical diagnostic value and accuracy of CT examination in patients with preoperative and postoperative recurrence of colon cancer

目的:分析结肠癌术前诊断及结肠癌术后复发诊断中CT检查的应用机制及效果。方法:2017年1月-2020年8月收治疑似结肠癌及术后复发结肠癌患者47例,以手术病理检查结果为标准,分析CT诊断的检出率、敏感度、特异度及病理分期诊断符合率。结果:CT诊断结肠癌及术后复发结肠癌的检出率、敏感度、特异度与手术病理诊断结果比较,差异无统计学意义(P>0.05);CT诊断结肠癌T分期、N分期检出率低于病理检查结果,差异有统计学意义(P<0.05);CT诊断M分期检出率与病理检查结果比较,差异无统计学意义(P>0.05)。结论:结肠癌术前诊断及术后复发性评估诊断实施中应用CT诊断,对于患者病灶临床检出具有显著应用价值,且可有效反应病灶转移情况,为手术治疗方案及预后治疗实施提供完善诊疗依据,应用价值显著。

Objective:To analyze the application mechanism and effect of CT examination in preoperative diagnosis and postoperative recurrence diagnosis of colon cancer.Methods:From January 2017 to August 2020,47 patients with suspected colon cancer and postoperative recurrent colon cancer were selected,based on the results of surgical pathology,we analyzed the detection rate,sensitivity,specificity of CT diagnosis and the coincidence rate of pathological staging.Results:The detection rate,sensitivity and specificity of CT in the diagnosis of colon cancer and postoperative recurrent colon cancer were not significantly different from those of surgical pathology(P>0.05).The detection rate of T stage and N stage of colon cancer diagnosed by CT was lower than that of pathological examination,the difference was statistically significant(P<0.05).There was no significant difference in the detection rate of M stage between CT and pathological examination(P>0.05).Conclusion:The application of CT in preoperative diagnosis and postoperative recurrence evaluation of colon cancer has significant application value for clinical detection of lesions,it can effectively reflect the metastasis of the lesions,and provide a perfect basis for the implementation of surgical treatment and prognosis,the application value is remarkable.
