What is it about?

This is the first report of the measurement of pancreatic enzyme activity in bile used In human medicine when pancreatobiliary maljunction in cats. At the same time, we also observed the biliary morphology of cats and investigated the relationship with pancreatic enzyme activity in bile.

Why is it important?

healthy cat CBDs were straight in all cases, whereas the CDs were variably tortuous or dilated. Amylase activity in the bile (median, <100 U/L; range, <100-591 U/L) was lower than in serum in all cases.Group with thick cystic duct had significantly higher amylase activity (median, 109 U/L; range, <100-591 U/L) in the bile than did group with thin cystic duct (median, <100 U/L; range, <100-238 U/L), (P = .0009).


The results suggest that a dilated CD is associated with reflux of pancreatic juice. In the future, it will be necessary to examine the clinical usefulness of these findings by measuring pancreatic enzyme activity in the bile of cats with cholangitis.
