CT仿真内镜对原发性小肠恶性肿瘤的诊断价值

The diagnostic value of CT virtual endoscopy in diagnosis of primary malignant tumors of small intestine

目的探讨CT仿真内镜（CTVE）对原发性小肠恶性肿瘤的诊断价值。方法 选择河北省唐山市中医医院2010年1月~2014年10月收住院的疑似小肠肿瘤并行CTVE检查的患者53例。对CTVE检查结果与手术或内镜活检病理诊断进行一致性检验分析,观察CTVE诊断原发性小肠恶性肿瘤的准确度、灵敏度、特异度。结果 手术或内镜活检病理诊断结果显示,53例患者中,原发性小肠恶性肿瘤29例,良性肿瘤24例。CTVE检查结果：小肠原发性恶性肿瘤30例,良性肿瘤23例。两种方法诊断原发性小肠恶性肿瘤的一致性较好（Kappa值=0.75）,CTVE诊断原发性小肠恶性肿瘤的准确度、灵敏度、特异度分别为90.6%、93.1%、87.5%。结论 CTVE技术操作简单、安全、无创伤性,易被患者接受。CTVE诊断原发性小肠恶性肿瘤的敏感度、特异度、准确度较高,具有较好的临床应用价值。

Objective To explore the diagnostic value of CT virtual endoscopy （CTVE） for patients with primary malig- nancy of small intestines. Methods 53 cases of eider patients in Hospital of Traditional Chinese Medicine in Tangshan City suspected small intestinal tumor were selected as subjects from January 2010 to October 2014. All patients were underwent CTVE examination. The consistency between CTVE and operation or endoscopic biopsy pathological diagno- sis was analyzed. The accuracy, sensitivity, specificity of CTVE were observed in diagnosis of primary malignant tumors of small intestine. Results The results of operation or endoscopic biopsy pathological examination showed that, among 53 patients, 29 cases were primary malignant tumors of the small intestine, 24 cases were benign tumor of all the cases. The results of CTVE showed that, 30 cases were primary malignant tumors of the small intestine, 23 cases were benign tumor of all the cases. Consistency test result showed that the two methods had good consistency （Kappa=0.75）. The ac- curacy, sensitivity, specificity of CTVE were 90.6%, 93.1%, 87.5%. Conclusion CTVE technology has the advantages of simple operation, safe, noninvasive, easy to be accepted by patients. In the diagnosis of primary malignant tumors of the small intestine, the sensitivity, specificity and accuracy arc higher, it has a good clinical application value.
