AbstractObjective：Toevalute andcomparetheaccuracyandsafetyofrobot-asstednavigationsystemforCT-guided percutaneous abdominallesionpunctureagainst thatofconventionalfreehandpuncture techniques.Methods： 40patientswhounderwentabdominal puncture proceduresattheSecondAfiliated HospitalofSoochow UniversityfromAugust2021toNovember2O21wereenroled. Participants were randomly divided into the experimental group scriptstyle（n=20 ）and the control group（ n=. 20）using the sealed envelope method. The experimentalgroupunderentpuncturepositioningviarobot-assistednavigationsystem，whilethecontrolgoupreceivedcoetional freehandpuncturepositioning.Theprimaryoutcomewasthefirst-passsuccessrateofpuncture，andsecondaryoutcomesincluded intraoperativeneedleadjustmentfrequencyandnumberofCTscans.Results：Theexperimentalgroupachievedasignificantlyhigher first-pass success rate （100 % ） compared to the control group （0% 1 （P<0.01 ）. The experimental group required no needle adjustments and hadanaverageof2.98CTscans，whichweresignificantlybetter thanthecontrolgroup's1.85nedleadjustmentsand48OCscans 0 P <0.01）.Minorbleedingoccuedinbothgroups，equiringnospecifictreatment.Thecomplicationrateintheexperimentalgroup（1 0% ） was lower than that in the control group （20%） .
