Consideration of hepatic factor influence on drip infusion cholangiography.

The plasma disappearance rate (K) and transfer rate constants for the two compartmental system of Indocyanine Green (ICG) were calculated in visualized and nonvisualized cases of the biliary tract with hepatobiliary disease using drip infusion cholangiography (DIC). In nonvisualized cases with hepatocellular disorder K and the fractional hepatic removal rate mainly decreased, and in nonvisualized cases with cholelithiasis the fractional biliary secretory rate significantly decreased by DIC-A, utilizing it as a screening test. Three methods (B,C and D) of drip infusion cholangiography were established according to the result of the I-CG test. Through DIC-B, C- or -D in addition to DIC-A the visualization of the biliary tract significantly elevated in patients with hepatocellular disorder and cholelithiasis. These results were confirmed using 131I-iodipamide. In some cases the serum transaminase activity elevated, but the elevation was temporary.
