[Modern pancreatic function tests].

The functional diagnostics is a corner-pillar of the difficult diagnostics of pancreas. Despite new tests many wishes remain open. The secretine-pancreozymine test and the Lundh-test give good informations, but they are expensive and for the patients considerably stressing. They certainly are not regarded as screening tests. The suitable and justifiable tests for epidemiologic examinations (estimations of stool enzymes and of serum isoamylase) are less specific and sensitive. A differentiation between chronic pancreatitis and neoplasm of the pancreas is not possible with the help of the functional diagnostics. The results of functional examinations may be correctly evaluated only within all informations which concentrate at the patient's bed.
