Abstract |
Authors analysed biochemical studies and scintigraphic
findings of obstructive jaundice and nonobstructive
jaundice in 44 cases of Tc-99m-DISIDA scintigraphy with
nonvisualization of biliary excretion till 120 min or
240 min after injection of Tc-99m-DISIDA. Causative
diseases of Tc-99m-DISIDA scintigraphy with
nonvisualization of biliary excretion were in order to
choledocholithiasis (25%), hepatitis (25%),
cholangiocarcinoma (14%), cholangitis (14%) and
pancreas head tumor (11%). In obstructive jaundice,
statistically significant findings were elevated
alkaline phosphatase above 300 IU/L on biochemical
study and single lobe enlargement of the liver,
irregular radioisotope uptake of the liver and concave
indentation of the gall bladder fossa of the liver on
scintigraphy. In nonobstructive jaundice, statistically
significant findings were persistent renal excretion of
Tc-99m-DISIDA and more increased uptake density of the
heart than the liver on scintigraphy. |
