In two minipigs chronic pancreatic and duodenal fistulas, which allowed the diversion and the intestinal replacement of pancreatic secretion, were prepared. In a third minipig a chronic biliary fistula was also prepared so the bile secretion could be fed back into the intestine through a duodenal catheter. In these animals a chronic gastric fistula was made so gastric secretion could also be collected. Diversion-replacement of pure pancreatic juice and of bile were carried out in the fasting state. This study confirms the presence of a feedback regulatory mechanism in exocrine pancreatic secretion in the pig. Moreover, it suggests that bile can interfere with this phenomenon.

Abstract
In two minipigs chronic pancreatic and duodenal fistulas, which allowed the diversion and the intestinal replacement of pancreatic secretion, were prepared. In a third minipig a chronic biliary fistula was also prepared so the bile secretion could be fed back into the intestine through a duodenal catheter. In these animals a chronic gastric fistula was made so gastric secretion could also be collected. Diversion-replacement of pure pancreatic juice and of bile were carried out in the fasting state. This study confirms the presence of a feedback regulatory mechanism in exocrine pancreatic secretion in the pig. Moreover, it suggests that bile can interfere with this phenomenon.
