摘　　要：目的:探讨CT仿真内窥镜成像(CTVE)在早期胃癌中的诊断价值。方法:选取2016年6月至2017年7月河北省石家庄市第一医院收治的疑似早期胃癌患者110例,均接受CTVE、X线钡餐造影、电子内镜检查,并以手术病理诊断为金标准,评估3种检查方法的诊断价值。结果:经手术病理检查确诊为早期胃癌87例(79.09%),良性病变23例(20.91%);CTVE检出早期胃癌80例(72.73%),X线钡餐造影检出67例(60.91%),电子内镜检出69例(62.73%);CTVE诊断敏感度为88.51%,特异度为86.96%,准确率为88.18%,阳性预测值为96.25%,阴性预测值为66.67%,kappa值为0.679,与病理诊断一致性较好;CTVE诊断早期胃癌的曲线下面积为0.877(95%CI:0.789~0.966),高于X线钡餐造影的0.830(95%CI:0.742~0.918)与电子内镜诊断的0.842(95%CI:0.755~0.928)。结论:CTVE在早期胃癌诊断中具有较高应用价值,诊断特异度、敏感度、准确度均较高,且与病理诊断结果一致性较好,值得临床推广。Objective:To evaluate the diagnostic value of CT virtual endoscopy(CTVE)in early gastric cancer.Methods:110 patients with suspected early gastric cancer were enrolled in this study.CTVE,X-ray barium meal and electronic endoscopy were performed.The results were compared with the pathological results.Results:87 cases(79.09%)of early gastric cancer and 23 cases(20.91%)of benign lesions were diagnosed by pathology.80 cases(72.73%)of early gastric cancer were detected by CTVE,67 cases(60.91%)were detected by X-ray barium meal,and 69 cases(62.73%)were detected by endoscopy.The sensitivity of CTVE was 88.51%,the specificity was 86.96%,the accuracy rate was 88.18%,the positive predictive value was 96.25%,the negative predictive value was 66.67%,and the kappa value was 0.679.The area under the ROC curve of CTVE in the diagnosis of early gastric cancer was 0.877,which was higher than that of X-ray barium meal(0.830)and electronic endoscopy(0.842).Conclusion:CTVE was valuable in the diagnosis of early gastric cancer.It had high diagnostic specificity,sensitivity and accuracy.
