[Diagnosis of pancreatic insufficiency with fluorescein dilaurate in patients with cystic fibrosis (author's transl)].

The tubeless pancreas-function test with fluorescein dilaurate, which is based on the saponification of the test substance by pancreas-specific arylesterases, and which has proved itself in adults, was given to children for the first time. After reduction of the size of the test dose and the amount of liquid to be drunk, there were no difficulties in carrying out the test. Elimination of the fluorescein released from the flourescein dilaurate and excreted via the kidneys was clearly less in patients with cystic fibrosis than in normal subjects. Thus, the test in its modified form for children can provide adequate differentiation between normal and pathological pancreas function.
