Abstract |
The present study has been undertaken to analyze scan
manifestation in obstructive jaundice. Scan changes
were correlated with the duration of jaundice. In
addition, clearance rates of trace dose of colloidal
radiogold were assessed in each case. The materials
were consisted of 19 cases with surgically and/or
histopathlogically verified obstructive jaundice from
various causes including common duct stone, empyema of
the gall bladder and carcinoma of the pancreas head
etc. Blood clearance rates of colloidal 198Au were
determined after the injection of 8 uCi by simple
geometrical drawing of recorded strip charts. Scan was
performed following additional injection of the sam
radiogold. In 16 out of 19 cases, the scan rather
typical "arborifrom" mottlings around the porta
hepatis. The intensity and appearance of such mottlings
on the scan was related with the duration of jaundice
and level of serum bilirubin and alkaline phosphatase.
The blood clearance rates remained to be within normal
range in 74 percent of the patients. In the remaining
26 percent, clearance rate ranged between 4.1 and 6
minutes. It is concluded that the association of
"arboriform" mottlings and normal or midly delayed
clearance rates in the patients with jaundice is
characterisic of obstructive change in the biliary
system.
