小肠CT仿真内镜对小肠疾病的诊断价值

Diagnostic value of CT virtual endoscopy in small bowel disease

目的:探讨小肠计算机断层扫描(computed tomography,CT)仿真内镜对小肠疾病的诊断价值.方法:收集2013-04/2014-04南阳医学高等专科学校第一附属医院收治的84例小肠疾病患者临床资料,按照不同的诊断方法,将患者分为观察组与对照组,观察组患者采取小肠CT仿真内镜诊断,对照组患者采取小肠双对比造影诊断,比较两组小肠控充盈效果以及敏感度、特异性和误诊率.结果:观察组患者充盈效果显著优于对照组(66.67%vs 40.48%),差异具有统计学意义(P<0.05);观察组敏感度、特异性均显著高于对照组(95.24%vs 59.52%、90.48%vs47.62%),误诊率显著低于对照组(0.00%v s26.19%),差异具有统计学意义(P<0.05).结论:应用小肠CT仿真内镜进行诊断小肠疾病,操作简单安全,充盈效果好,敏感度和特异性均较高,值得临床推广.

AIM： To explore the diagnostic value of computed tomography （CT） virtual endoscopy in small bowel disease. METHODS： Eighty-four patients with small bowel disease were divided into either an observation group or a control group. The observation group underwent CT virtual endoscopy, and the control group underwent double contrast imaging of the small intestine. The filling effect, sensitivity, specificity, and the rate of misdiagnosis were compared for the two groups. RESULTS： The filling effect for the observation group was higher than that for the control group （66.67% vs 40.48%, P 〈 0.05）. The diagnostic sensitivity and specificity for the observation group were higher than those for the control group （95.24% vs 59.52%, 90.48% vs 47.62%, P 〈 0.05）. The rate of misdiagnosis for the observation group was lower than that for the control group （0.00% vs 26.19%, P 〈 0.05）. CONCLUSION： The diagnostic value of CT virtual endoscopy in the detection of small bowel disease is good, and it is simple, safe and has good filling effect, high sensitivity and specificity.
