[Diagnosis of pancreatic diseases in childhood (author's transl)].

In many ways diagnosis of pancreatic disorders in children is difficult. Since pancreatic parameters are age-dependent, reliable laboratory parameters are not easily established. Children are less likely than adults to endure tolerance tests and invasive test methods should therefore be used only in special situations. Estimation of chymotrypsin in faeces seems to be an earlier indicator of pancreatic insufficiency than the PABA-peptide-test. A secretin-pancreozymin test can only be advised for first diagnosis after screening has repeatedly indicated pathological values and malabsorption has more or less been ruled out. A threefold rise in serum amylase values - matched for age - suggests pancreatitis and sonography should then be applied to obtain further clarification.
