Background:
Little is known about exocrine pancreatic function during human acute pancreatitis. We aimed to evaluate interdigestive exocrine pancreatic secretion and pancreatic polypeptide (PP) release during the early phase of acute pancreatitis in humans.
Methods:
Eight patients with acute pancreatitis (six biliary, one alcoholic, and one idiopathic acute pancreatitis) were studied within 72 h from the onset of symptoms. Four patients had necrotizing and four had edematous acute pancreatitis. Normal values were obtained from 26 normal subjects matched by sex and age. Interdigestive pancreatic secretion was studied by a duodenal intubation perfusion technique. Enzyme output was calculated for consecutive 15-min periods over 3-4 h and expressed as units per hour within a secretion cycle and units per hour around a secretion peak. Plasma PP concentrations were measured by radioimmunoassay in 15-min intervals.
Results:
All variables studied were similar in patients with acute pancreatitis and in controls. PP release in acute pancreatitis was maintained in a normal cyclical pattern closely related to the secretory cycles.
Conclusions:
Interdigestive exocrine pancreatic secretion in the early phase of mild to moderate acute pancreatitis in humans remains within the normal range. This finding provides a rational basis for early therapeutic inhibition of pancreatic secretion in human acute pancreatitis.

Pancreatic Juice and Secretion
When acidic chyme from the stomach enters the duodenum, it triggers the release of secretin, a hormone that prompts pancreatic juice secretion. After a fatty meal, cholecystokinin, another hormone, stimulates gallbladder contraction and enhances enzyme-rich...
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
