Endoscopic retrograde pancreatography and exocrine pancreatic function

Area of Science:

• Gastroenterology
• Diagnostic Imaging
• Alcohol-Related Diseases

Background:

• Increasing incidence of pancreatitis correlates with rising alcohol consumption.
• Traditional chronic pancreatitis diagnosis relied solely on exocrine function tests.
• Limitations of solely relying on exocrine function for early diagnosis.

Purpose of the Study:

• To evaluate the utility of endoscopic retrograde pancreaticography (ERP) and pancreatic ultrasonography in diagnosing chronic pancreatitis.
• To compare diagnostic findings from imaging techniques with exocrine pancreatic function tests.
• To assess the prevalence of 'subclinical pancreatitis' in chronic alcoholics.

Main Methods:

• Consecutive series of patients with chronic alcoholism.
• Utilized endoscopic retrograde pancreaticography (ERP) for pancreatogram analysis.
• Employed pancreatic ultrasonography as a complementary diagnostic tool.
• Compared imaging results with exocrine pancreatic function estimations.

Main Results:

• Abnormal pancreatogram findings were observed in approximately 44% of chronic alcoholic patients.
• Significant reduction in exocrine pancreatic function was only evident in patients with advanced pancreatic lesions.
• Imaging techniques revealed changes not detected by function tests alone, suggesting frequent 'subclinical pancreatitis'.

Conclusions:

• Endoscopic retrograde pancreaticography (ERP) and pancreatic ultrasonography offer valuable insights into pancreatic disease.
• These imaging modalities are effective in identifying pancreatitis in alcoholics, including subclinical cases.
• Combined use of ultrasonography and ERP is recommended for early and accurate pancreatic disease diagnosis.
