The diagnostic value of the oral pancreatic function test
Scandinavian Journal of Gastroenterology
|January 1, 1979
Summary
This study evaluated an oral pancreatic function test (PFT) for assessing exocrine function. While effective for pancreatitis, the PFT showed false positives in patients with bowel or liver disease, limiting its diagnostic specificity.
Area of Science:
- Gastroenterology
- Diagnostic Medicine
- Biochemistry
Background:
- Pancreatic exocrine function is crucial for digestion.
- Assessing pancreatic exocrine function aids in diagnosing conditions like pancreatitis.
- Existing diagnostic methods may have limitations.
Purpose of the Study:
- To evaluate the diagnostic accuracy of an oral pancreatic function test (PFT).
- To assess the utility of the synthetic peptide N-benzoyl-L-tyrosyl-p-aminobenzoic acid for measuring chymotryptic activity.
- To determine if the PFT can differentiate pancreatic disease from other gastrointestinal conditions.
Main Methods:
- A study involving 34 subjects, including healthy controls and patients with pancreatitis.
- Utilized an oral pancreatic function test (PFT) measuring urinary recovery of a synthetic peptide.
- Correlated PFT results with Lundh test findings.
Main Results:
- The oral PFT correctly identified patients with pancreatitis compared to controls.
- PFT results showed good correlation with Lundh test findings.
- The test produced false-positive results in 9 out of 16 patients with bowel or liver disease.
Conclusions:
- The oral PFT can assess pancreatic exocrine function and identify pancreatitis.
- The test lacks specificity, frequently yielding abnormal results in patients with small-bowel or chronic liver disease.
- Distinguishing pancreatic disease from small-bowel disease remains a diagnostic challenge with this PFT.
