[The significance of trypsin, amylase and lipase activities in the blood serum for the differential,diagnosis of chronic pancreatitis and other diseases of the abdominal organs].

An investigation of 122 patients with chronic recurrent pancreatitis at different stages of the disease revealed that the most important informative diagnostic value belongs to the level of blood serum trypsin. Transition to the remission stage may be considered only after normalization of the parameters of blood pancreatic enzymes which showed in 1/4 of all cases a 1-2 week delay in normalization of clinical signs of exacerbation. The level of pancreatic amylase, lipase and trypsin in the blood is not able to characterize the external secretory activity of the pancreas but is reflecting the phenomenon of enzyme "deviation" depending on the degree of destructive processes in the pancreas.
