简介：AIM:Toevaluateshort-termoutcomesfollowingintraoperativebiliarylavageforhepatolithiasis.METHODS:Atotalof932patientswhowereadmittedtotheWestChinaMedicalCenterofSichuanUniversitybetweenJanuary2010andJanuary2014andunderwentbileductexplorationandlithotomywereretrospectivelyincludedinourstudy.Thepatientsweredividedintothelavagegroupandthecontrolgroup.Relatedpre-,intra-,andpostoperativefactorswererecorded,analyzed,andcomparedbetweenthetwogroupsinordertoverifytheeffectsofbiliarylavageontheshort-termoutcomeofpatientswithhepatolithiasis.RESULTS:Amongstthepatientswhowereincluded,678patientswithhepatolithiasiswereincludedinthelavagegroup,andtheother254patientswereenrolledinthecontrolgroup.Dataanalysesrevealedthatpreoperativebaselineandrelatedintraoperativevariableswerenotsignificantlydifferent.However,patientswhounderwentintraoperativebiliarylavagehadprolongedpostoperativehospitalstays(6.67dvs7.82d,P=0.024),higherhospitalizationfees(RMB28437.1vsRMB32264.2,P=0.043),higherpositiveratesofbacterialculturesfromblood(13.3%vs25.8%,P=0.001)andbile(23.6%vs40.7%,P=0.001)samples,andincreasedusageofadvancedantibiotics(26.3%vs38.2%,P=0.001).Inaddition,inthelavagegroup,morepatientshadfever(>37.5℃,81.4%vs91.1%,P=0.001)andhyperthermia(>38.5℃,39.7%vs54.9%,P=0.001),andhigherwhitebloodcellcountswithin7daftertheoperationcomparedtothecontrolgroup.CONCLUSION:Intraoperativebiliarylavagemightincreasetheriskofpostoperativeinfection,whilenotsignificantlyincreasinggallstoneremovalrate.
