[Effect of various reconstructions of biliary tract upon secretion of gastric acid and gastrointestinal hormones in dogs]. 1983

M Imamura

Experimental studies were carried out to investigate the effect of various biliary tract reconstructions upon the secretion of gastric acid and gastrointestinal hormones. Jejunal interposition cholecystoduodenostomy with a short jejunal segment (Group-I), jejunal interposition cholecystoduodenostomy with a long jejunal segment (Group-II), and Roux-en-Y cholecystojejunostomy (Group-III) were constructed in seventeen Heidenhain pouch dogs. Peptic ulcer was only observed in 2 out of 7 dogs of Group-III. Although food-stimulated gastric acid output did not differ significantly in all the groups, the amount of gastric acid reached a peak much later and remained elevated in Group-III compared with that in other groups. The changes in plasma gastrin, gastric inhibitory polypeptide and total glucagon are regarded to be affected by the length of the jejunum excluded from the stream of chyme and the direct contact of the jejunum with bile. It is concluded that the pattern of acid secretion is more important than its volume for the mechanism of peptic ulceration in Roux-en-Y cholecystojejunostomy.
