Summary
Accurate diagnosis of chronic pancreatitis relies on correlating imaging findings with function tests, especially in early stages. Combining imaging and function testing improves diagnostic accuracy for mild morphological abnormalities.
Area of Science:
- Gastroenterology
- Radiology
- Medical Diagnostics
Background:
- Chronic pancreatitis is a progressive disease with early focal changes and late diffuse abnormalities.
- Morphological changes in chronic pancreatitis can be detected by imaging methods like endoscopic retrograde pancreatography (ERP), ultrasonography (US), and computed tomography (CT).
- The correlation between morphological abnormalities and functional impairment is strong only in late stages of chronic pancreatitis.
Purpose of the Study:
- To evaluate the diagnostic accuracy of various imaging techniques and function tests in chronic pancreatitis.
- To assess the morphofunctional correlation in different stages of chronic pancreatitis.
- To determine the value of combining imaging and function testing for diagnosis and clinical decision-making.
Main Methods:
- Comparison of endoscopic retrograde pancreatography (ERP), high-resolution ultrasonography (US), and computed tomography (CT) for detecting ductal and parenchymal abnormalities.
- Correlation analysis between imaging findings (ductal and parenchymal) and pancreatic function tests (e.g., secretin test [SC test]).
- Evaluation of the diagnostic value of combining imaging techniques with function testing.
Main Results:
- Endoscopic retrograde pancreatography (ERP) is the most sensitive for early ductal changes; CT is superior to US for detecting small cysts and calcifications.
- Morphofunctional correlation is poor in early/moderate stages but tight in late/severe chronic pancreatitis.
- ERP and the secretin (SC) test show the highest diagnostic accuracies; combining imaging with function tests enhances accuracy for mild abnormalities.
Conclusions:
- Imaging methods accurately detect morphological changes in chronic pancreatitis, but morphofunctional correlation is stage-dependent.
- Combining imaging with function testing is crucial for diagnosing mild chronic pancreatitis and guiding therapeutic decisions in advanced stages.
- Oral pancreatic function tests can replace invasive tests like the SC test, offering equivalent results for clinical decisions.
