Abstract:
Objective ToexploretheclinicalvalueofMSCTcombinedwithultrasonographyinthediagnosisofacuteappendicitis. Methods 238patientswithsuspiciousappendicitisunderwentMSCTandultrasonographybeforesurgery.Allpatientsweredivided intoappendicitisgroupandnormalappendixgroupaccordingtoCTappearances.TheefficacyofMSCTcombinedwithultrasoundin diagnosingappendicitiswasanalyzedbycomparisonofsurgicalpathologicalfindings.Results Therewere220casesinappendicitis group,whichhad165casesofappendicitisconfirmedbypathology,and55casesofnormalappendix.Therewere18casesinnormal group,2caseswereconfirmedappendicitisbypathology,and16caseswerenormalappendix.Theoveralldiagnosticperformancesof theCTscanwere98.8%ofsensitivity,22.5%ofspecificity,82.5%ofpositivepredictivevalue,88.9%ofnegativepredictivevalue, and76.1%ofaccuracy.TheperformancesofMSCTcombinedwithultrasonographywere90.4%ofsensitivity,93.0%ofspecificity, 96.8%ofpositivepredictivevalue,80.5%ofnegativepredictivevalue,and91.2%ofaccuracy.Thedifferencewasstatisticallysignificant indiagnosisperformancesbeforeandafterMSCTcombinedwithultrasonography (P＜0.001).Conclusion MSCTcombinedwith ultrasonographyexaminationcouldimprovethediagnosticaccuracyofappendicitis,andmayreducethenegativerateofappendectomy.
