摘　　要：目的:探讨CT诊断结肠癌致肠梗阻的准确率。方法:采用回顾性方法分析,选取本院2016年1月~2020年5月收治的86例结肠癌致肠梗阻患者的临床资料,分别予以腹部X线、腹部CT检查,将手术病理组织检查结果作为本次研究的金标准,比较X线、CT诊断准确率、特异度、灵敏度,Kappa检验X线、CT与金标准的一致性,并分析CT影像学特点。结果:CT诊断准确率(96.51%)、特异度(75.00%)、灵敏度(97.56%)均高于X线(81.40%、25.00%、84.15%),P均<0.05(均存在统计学差异),CT与病理组织诊断比较,P>0.05,X线与病理组织诊断比较,P<0.05。X线与手术诊断结果的一致性一般(Kappa值=0.511),CT与手术诊断结果的一致性较好(Kappa值=0.782)。86例患者的肿瘤部位有45例位于回盲肠及升结肠,占52.33%,30例位于乙状结肠,占34.88%,8例位于直肠,占9.30%,3例位于横结肠,占3.49%。结论:结肠癌致肠梗阻诊断中采用CT检查有较高准确率、特异度及灵敏度,可为临床治疗方案的制定提供科学的参考依据。Objective:To explore the accuracy of CT diagnosis of intestinal obstruction caused by colon cancer.Methods:Retrospective analysis was used to select the clinical data of 86 patients with intestinal obstruction caused by colon cancer who were treated in our hospital from January 2016 to May 2020.Abdominal X-ray and abdominal CT examination were performed respectively,and the results of surgical pathological examination were compared.As the gold standard of this study,the diagnostic accuracy,specificity,and sensitivity of X-ray and CT were compared,and the consistency of X-ray,CT and the gold standard was tested by Kappa,and the imaging characteristics of CT were analyzed.Results:CT diagnosis accuracy(96.51%),specificity(75.00%),sensitivity(97.56%)are all higher than X-ray(81.40%,25.00%,84.15%),P<0.05(all statistically different),CT Compared with the diagnosis of pathological tissue,P>0.05,compared with the diagnosis of X-ray and pathological tissue,P<0.05.The consistency between X-ray and surgical diagnosis results is general(Kappa value=0.511),and the consistency between CT and surgical diagnosis results is good(Kappa value=0.782).Of the 86 patients,45 cases were located in the ileocecum and ascending colon,accounting for 52.33%,30 cases were located in the sigmoid colon,accounting for 34.88%,8 cases were located in the rectum,accounting for 9.30%,and 3 cases were located in the transverse colon,accounting for 3.49%.Conclusion:The use of CT in the diagnosis of intestinal obstruction caused by colon cancer has high accuracy,specificity and sensitivity,which can provide a scientific reference for the formulation of clinical treatment plans.
