评价CT结肠造影扫描技术在结肠占位病变性质诊断中的价值【摘要】目的：观察和评价分析CT结肠造影技术在结肠占位病变性质鉴别中的应用价值，为临床提供有效诊断方法和依据。方法：回顾性分析2014年1月至2016年12月于本院接受CT结肠造影技术治疗的76例患者临床诊断资料，以病理检测作为金标准，评价CT结肠造影检查技术在对结肠的占位病变中的诊断价值及对于结肠癌分期的临床意义。结果：入组患者均符合CT结肠造影检测技术的相关要求，患者分级中，I级有50例，II级有23例，III级仅有3例，患者检测前肠道的准备情况合格率为97.37%，所有患者均为出现不良反应的症状。CT结肠造影检查结果显示，39例患者可确诊为结肠癌，其中包含11患者同时出现腹腔淋巴结肿大，13例患者初诊为炎性息肉，15例患者初诊为腺瘤，6例患者初诊为转移癌，3例患者初诊为淋巴瘤。病理检查结果显示结肠癌患者共39例，炎性息肉患者16例，腺瘤患者13例，转移癌患者5例，淋巴瘤患者3例，以此作为金标准进行比较，CT结肠造影检查对结肠癌分期结果的符合率为96.05%（73/76），经检验，P<0.05。2例病理检测显示炎性息肉患者CT结肠造影检查结果为腺瘤，1例病理检测显示炎性息肉患者CT造影检查为转移癌，该检测技术误诊率为3.41%。CT结肠造影检查结果显示，A期9例、B期4例、C1期18例、C2期4例和D期4期。病理Dukes分期中A期7例、B期8例、C1期16例、C2期4例和D期4例，以病理分期诊断结果为金标准，CT结肠造影检查的符合率为89.74%（35/39），经检验，K=0.874，P=0.000。CT结肠造影检查中有2例B期患者被误诊为A期，2例B期患者被误诊为C1期，该检测技术的误诊率为10.26%。结论：CT结肠造影技术操作简单易行，实用价值及辅助诊断的价值更高，有利于临床上辅助诊断结肠的占位病变。【关键词】CT结肠造影；结肠占位病变；结肠癌分期；鉴别ThevalueofCTcolonographyinthediagnosisofcolonoccupyinglesion[Abstract]Objective:ToobserveandevaluatethevalueofCTangiographyintheidentificationofcoloniclesionsandprovideeffectivediagnosticmethodsandbasisforclinicaldiagnosis..METHODS:Aretrospectiveanalysisoftheclinicaldiagnosticdataof76patientstreatedwithCTcolonoscopyinourhospitalfromJanuary2014toDecember2016wasreviewed.PathologicalexaminationwasusedasagoldstandardtoevaluateCTcolonizationThediagnosticvalueoflesionsandtheclinicalsignificanceofcoloncancerstaging.Results:Therewere50patientswithgradeI,23casesofgradeII,3casesofgradeIIIand3casesofgradeIII.Thequalifiedrateofpreparationwas97.37%,allpatientsweresymptomsofadversereactions.CTcolonoscopyresultsshowedthat39patientswerediagnosedwithcoloncancer,including11patientswithsimultaneousabdominallymphnodes,13patientswerenewlydiagnosedwithinflammatorypolyps,15patientswerenewlydiagnosedadenoma,6patientswerenewlydiagnosedCancer,3patientswerenewlydiagnosedwithlymphoma.Pathologicalexaminationshowedthat39casesofcoloncancerpatients,16casesofinflammatorypolyps,13casesofadenomapatients,5casesofmetastaticcancerpatients,3casesoflymphomapatients,asagoldstandardforcomparison,CTcolonoscopyonthecolonThecoincidencerateofcancerstagingwas96.05%(73/76).Afterexamination,P<0.05.CTcolorectalexamination2casesofinflammatorypolypsweremisdiagnosedasadenoma,1caseofinflammatorypolypswasmisdiagnosedasmetastaticcancer,thedetectiontechniquemisdiagnosisratewas3.41%.CTcolorectalexaminationresultsshowedthatA,9cases,B4cases,C118cases,C24casesandDperiod4.PathologicalDukesstageAin7cases,B8cases,C116cases,C24casesandD4cases,thepathologicalstageoftheresultsofthegoldstandard,CTcolonyexaminationcoincidencerateof89.74%(35/39),tested,K=0.874,P=0.000.CTcolorectalexaminationin2casesofBpatientsweremisdiagnosedasAphase,2casesofBpatientsweremisdiagnosedasC1period,thedetectiont...
