摘　　要：目的分析CT常规扫描与CT小肠造影对小肠肿瘤的诊断价值。方法选取2019年11月至2021年10月赣南医学院兴国医院的35例疑似小肠肿瘤患者作为研究对象,以病理检查结果为金标准,比较128层螺旋CT常规扫描与128层螺旋CT小肠造影诊断小肠肿瘤的准确度、敏感度、特异度、阳性预测值、阴性预测值,并对比两种检查方式对各类型小肠肿瘤疾病的检出率。结果病理检查结果显示,35例疑似小肠肿瘤疾病患者中,阳性32例,阴性3例。32例阳性患者中,小肠脂肪瘤15例,小肠平滑肌瘤12例,腺瘤5例。CT小肠造影对小肠肿瘤疾病的诊断准确度为94.29%、敏感度为96.88%,CT常规扫描的诊断准确度为71.43%,敏感度为75.00%,CT小肠造影高于CT常规扫描,差异有统计学意义(P<0.05);CT小肠造影对小肠肿瘤疾病诊断的特异度为100.00%,阳性预测值为96.88%,阴性预测值为66.67%,CT常规扫描特异度为50.00%,阳性预测值为88.89%,阴性预测值为12.50%,两种检查方式比较差异无统计学意义(P>0.05)。两种检查方式对各类型小肠肿瘤疾病的检出率比较,差异无统计学意义(P>0.05)。结论对于小肠肿瘤患者,与CT常规扫描相比,CT小肠造影检查准确度、敏感度更高,诊断效能显著。Objective To analyze the diagnostic value of conventional CT scanning and CT enterography in small intestinal tumors.Methods Thirty-five patients with suspected small intestine tumor in Xingguo Hospital,Gannan Medical College from November 2019 to October 2021 were selected as the study objects.The result of pathological examination was the gold standard.The accuracy,sensitivity,specificity,positive predictive value and negative predictive value of 128-slice spiral CT and 128-slice spiral CT were compared in the diagnosis of small intestine tumors,and the detection rates of the two methods for different types of small intestine tumors were compared.Results Pathological examination results showed that 32 cases were positive and 3 cases were negative among 35 suspected patients with small intestine tumor disease.Among the 32 posi-tive patients,15 cases of small intestinal lipoma,12 cases of small intestinal leiomyoma,5 cases of adenoma.The diagnostic accuracy and sensitivity of conventional CT scan were 71.43%and 75.00%respectively,and CT small intestine contrast was higher than conventional CT scan,the difference was statistically significant(P<0.05).The specificity,positive predictive value and negative predictive value of CT enterography were 100.00%,96.88%and 66.67%respectively.The specificity,positive predictive value and negative predictive value of conventional CT scan were 50.00%,88.89%and 12.50%respec-tively.There was no significant difference between the two methods(P>0.05).There was no significant difference in the de-tection rate of dfferent types of small intestine tumor between the two methods(P>0.05).Conclusion For patients with small intestinal tumors,CT enterography has higher accuracy and sensitivity compared to conventional CT scanning,and has significant diagnostic efficacy.
