A total of 7o consecutive drip-infusion cholangiography v as performed in the Chonnam licdical University Hospital during periods of 1976 to 1979. The ages of the patients ranged from 21 to 73 years with the highest rank fifth decade. Of the patients 44 were male and 32 were female. In these patients a diagnostic evaluation of drip-infusion cholangiography was possible in 43 cases resulting in a diagnostic success rate of 56 percent. The gallbladder and the ductal systems were visualized with a equal success rate. The total bilirubin levels ranged from 0.4 mgA to 22.4mgZo In pstients with bilirubin levels below 1mg%, 29 of 38 cases in which biliary systems ivere visualized, and in the cases ivith bilirubin levels ranged from ll mgJo to 5. 2mgA 14 of 22 cases, were visualized. In the p."esent stdy the the highest level of serum bilirubin in a patients with adequate opacification of biliary systems was 5. 2mg%. Twenty-one patients were examined by both the conventional and drip-infusion cholangiogra- phy, and the results were compared. The drip-infusion cholangraphy offers a higher success rate over the conventional technic. Drip-infusion cholangiography using premedication with hyphertonic glucose solution and insulin rather causes nonvisulization of biliary systems in some cases. In only two cases developed dizziness.
