The role of hepatobiliary scintigraphy in differentiating acute cholecystitis from acute nonbiliary pancreatitis.
Thirty-five patients with acute nonbiliary pancreatitis were studied with 99m-Technetium para isoproply iminodiacetic acid in order to determine its ability to differentiate acute nonbiliary pancreatitis from acute cholecystitis. Of acute nonbiliary pancreatitis patients 90.3% (28/31) visualized their gallbladder in 1 h, 9.7% (3/31) had delayed visualization of gallbladder, and no patient in this category failed to visualize their gallbladder. Two of four patients with acute episodes of pancreatitis superimposed on chronic pancreatitis visualized their gallbladder. Biliary scintigraphy remains to be a valuable tool in differentiating acute nonbiliary pancreatitis from acute cholecystitis.
