摘要
AIM:Toinvestigatethediagnosticaccuracyofthemeanplateletvolumeandplateletdistributionwidthinacuteappendicitis.METHODS:Thisretrospective,case-controlledstudycompared295patientswithacuteappendicitis(Group?Ⅰ),100patientswithotherintra-abdominalinfections(GroupⅡ),and100healthyindividuals(GroupⅢ)betweenJanuary2012andJanuary2013.Theage,gender,andwhitebloodcellcount,neutrophilpercentage,meanplateletvolume,andplateletdistributionwidthvaluesfrombloodsampleswerecomparedamongthegroups.StatisticalanalyseswereperformedusingSPSSforWindows21.0software.Inaddition,thesensitivity,specificity,positiveandnegativepredictivevaluesandlikelihoodratios,anddiagnosticaccuracywerecalculated.RESULTS:Themeanagesofpatientswere29.9±12.0yearsforGroup?Ⅰ,31.5±14.0yearsforGroupⅡ,and30.4±13.0yearsforGroupⅢ.Demographicfeaturessuchasageandgenderwerenotsignificantlydifferentamongthegroups.Whitebloodcellcount,neutrophilpercentageandplateletdistributionwidthweresignificantlyhigherinGroup?Ⅰ?comparedtogroupsⅡandⅢ(P<0.05).Diagnostically,thesensitivity,specificityanddiagnosticaccuracywere73.1%,94.0%,and78%forwhitebloodcellcount,70.0%,96.0%,and76.0%forneutrophilpercentage,29.5%,49.0%,and34.0%formeanplateletvolume,and97.1%,93.0%,and96.0%forplateletdistributionwidth,respectively.ThehighestdiagnosticaccuracydetectedwasforplateletdistributionwidthbetweenGroup?Ⅰ?andGroupⅢ(P<0.01).CONCLUSION:Plateletdistributionwidthanalysiscanbeusedfordiagnosisofacuteappendicitiswithoutrequiringadditionaltests,thusreducingthecostandlossoftime.
