Abstract:
Objective To evaluate the value of preoperative color Doppler flow imaging findings for predicting possible difficuulties encountered during laparoscopic cholecystectomy (LC).Methods Eighty-six Datients with acute cholecystitis underwent color Doppler flow imaging examination were divided into operation difficult group(67 cases)and operation easy group(19 cases)according to the diffculty score.The parameters were measured pre-operation including the volume of gallbladder,the thickness of the gallbladder wall,the condition of arterial flow in the gallbladder wall,the conditions of gallbladder cavity and gallbladder fossa and the intra-and extra-hepatic bile duet.The relationships among imaging results,operation difficulties and operation findings were investigated.Results Gallbladder volume,gallbladder wall thickness.the presence rates of plentiful arterial flow in the gallbladder wall,adhesion of gallbladder and stone incarceration In operation difficult group were significantly different from those in operation easy group [(52.6±14.6)mm~3 vs(32.6±10.4)mm~3,(9.7±4.1)mm vs(3.8±0.9)mm,89.5%(17/19)vs 17.9%(12/67),78.9%(15/19)vs 11.9%(8/67),10.5%(2,19)vs 0(0/67)](P<0.05 or<0.01).The accurate rate was 94.2%(81/86)in predicting.Conclusion Preoperative color Doppler flow imaging is helpful in predicting difficulties of LC.
