title: The pancreas: a correlation of function and structure.
abstract: Fifty-two patients with or without pancreatic disease were studied with both secretin test and endoscopic retrograde pancreatography. Pancreatic histopathology was obtained by exploratory laparotomy in half of these patients. The following conclusions were reached: 1. Secretory tests are the most sensitive indicators of chronic pancreatitis, although not all cases of chronic pancreatitis will be discovered by this test. 2. When secretory tests show low volume output, pancreatography is crucial in differentiating between malignant ductal obstruction or pancreatic replacement by fibrosis or atrophy. 3. Histologic correlation with ductular structure and/or secretin function is frequently discordant. 4. The secretin test and pancreatogram measure different parameters and the use of both these complementary studies will lead to increased diagnostic accuracy and better understanding of pancreatic pathophysiology.
