ULTIRASONOGRAPHIC DIAGNOSIS OF CHOLELITHIASIS(An analysis of 143 cases)

The ultrasonographic materials of 143 cases of nocholelithiasis proved operatively and pathologically are analyzed.Among these,the sographic diagnostic sensitivity was 94.4%,specificity 92.3%,overall accuracy 93.8%.The sonographic appearances were classified into four categories:1.The typical signs account for 84.6%. These appear as intraluminal high level echoic clumps with distal shadowing, which move with gravity and/or demonstrate at least in two different scanning sections.2.Nonvisualization of gallbladder 8.4%.In all but one case,they present as shadowing opacities in gallbladder fossa.3.Nonshadowing opacities within the gallbladder lumen 2.1%.4.False negative diagnosis 4.9%. Some problems concerning sonographic qualitative diagnosis,quantitative diagnosis and the diagnosis of complications or coexisted dIseases of cholelithi- asis are discnssed.The authors are of the opinion that ultrasonography should be used as the first imaging examined method of choice to discover and diagno- se cholelithiasis;and that in the course of abdominal sonography,the liver, biliary tract,pancreas,spleen and both kidneys should be coventionally scanned so as to avoid that we failed to discover the synchronous or correlative diseases.
