[Diagnosis of pancreatic diseases in childhood (author's transl)]
Insights
Diagnosing pancreatic disorders in children is challenging due to age-dependent parameters. Fecal chymotrypsin is a useful early indicator of pancreatic insufficiency in pediatric patients.
Area of Science:
- Pediatric Gastroenterology
- Pancreatic Physiology
- Diagnostic Laboratory Medicine
Context:
- Pancreatic disorder diagnosis in children presents unique challenges.
- Age-dependent physiological parameters complicate laboratory test interpretation.
- Pediatric patients often tolerate invasive diagnostic procedures poorly.
Purpose:
- To review diagnostic challenges and recommend appropriate methods for pediatric pancreatic disorders.
- To highlight reliable and less invasive diagnostic markers for early detection.
- To provide guidance on the appropriate use of specific diagnostic tests.
Summary:
- Pediatric pancreatic function tests are complicated by age-dependent parameters.
- Fecal chymotrypsin estimation is an earlier indicator of pancreatic insufficiency than the PABA-peptide-test.
- The secretin-pancreozymin test is reserved for confirmed cases after initial screening, and age-matched serum amylase elevation suggests pancreatitis, warranting sonography.
Impact:
- Improved diagnostic strategies for pediatric pancreatic diseases.
- Earlier and more accurate identification of pancreatic insufficiency in children.
- Reduced use of invasive procedures in pediatric pancreatic diagnostics.
Abstract:
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.
