3、临床上怀疑有肠套叠的患者,入选标准如下:(1)有肠套叠临床表现(2)均行腹部平片与腹部超声(3)临床资料全而且能提供金标准的患者(金标准包括:手术病理,灌肠,随访),分别计算其US及X线诊断肠套叠的灵敏度、特异度、误诊率、漏诊率、阳性似然比、约登指数、符合率、阳性预测值、阴性预测值,评价诊断试验的真实性、可靠性及收益。结果:总共纳入了95例患者,其屮男为53(55.8%)例,女为42(44.2%)例。金标准确诊为肠套叠病人共有81例,确诊不是为肠套叠的病人共有14例,其中手术确诊为肠套叠病人有53
4、例,空气灌肠21例,随访病人(自行解套)7例。腹部平片敏感度为70.4%(95%confidenceinterval[CI],60.4%〜80.3%),特异度为57.1%(95%CI,31.2%〜83」%),腹部超声的敏感度及特异度分别为95.1%(95%CI,90.3%〜99.8%)及78.6%(95%CI,57.1%〜100%),腹部超声较腹部平片有很好的阴性预测值(73%vs25%)及阳性预测值(96.3%vs90.5%),腹部平片较腹部超声有更大的假阳性率(42.9%vs21.4%)及假阴
5、性率(29.6%vs4.9%)o结论:超声检查在诊断肠套叠中的灵皱度及特异度均高于腹部X线平片检查,故超声检查在肠套叠的诊断及筛选中优于腹部X线平片检查,超声可作为肠套叠的首选检查方法。关键词:肠套叠,超声,X线ComparetheclinicalvalueoftheultrasonicdiagnosisandX-raydiagnosisintheintussusceptionPostgraduate:Meiheriayi6、stractObjective:ThisstudyaimedtocomparetheclinicalvalueoftheultrasonicdiagnosisandX-raydiagnosisintheintussusception.Methods:Retrospectivecohortofpatientage1monthsto64yearspresentingtoTheFirstAffiliatedHospitalofXinjiangMedicalUniversitybetweenOctober7、2008toOctober2013・Inclusioncriteriawereasfollows:1.Intussusceptionclinicalmanifestations^,both2-viewAXRandUSperformedduringthevisit.3.ClinicaldatacomprehensiveandapplytotheCriterionstandardmeasuresforintussusceptionwereoperativereport,contrastenemaorf8、ollow-up,thencalculatingspecificity,sensitivity,misdiagnosisrate,rateofmisseddiagnosis,positivelikelihoodratio,yorcTSindex,coincidencerate,positivepredictivevalue,negativepredictivevalue.EstimatingThercliability.facticityAndprofityDiagnositict
