Abstract

We diverted bile and pancreatic juice from jejunal blind loops of different lengths in conscious rats to see if the pancreatic secretory response was dependent on the length of the jejunal blind loop. Short-term bile and pancreatic juice diversion from a short jejunal blind loop, representing only 8-10% of the total length of the small intestine, stimulated a significant increase in pancreatic exocrine secretion. Short- term bile and pancreatic juice diversion from jejunal blind loops of increasing length resulted in a progressive decrease in the pancreatic secretory response to diversion (i.e., there appears to be a length-dependent inhibition of the pancreatic secretory response to short-term bile and pancreatic juice diversion from the jejunum). Cholinergic receptor blockade with atropine eliminated this length-dependent inhibition of pancreatic exocrine secretion during short-term bile and pancreatic juice diversion. In contrast to what was observed with short-term bile and pancreatic juice diversion, there was a length-dependent increase in pancreatic secretion during long-term bile and pancreatic juice diversion. The jejunal-bypass rat model can facilitate the investigation of the intestinal mechanisms mediating feedback regulation of pancreatic exocrine secretion.
