Abstract

The effect of diverting bile from the duodenum in four dogs with cholecystojejunostomy was studied using a double-marker perfusion technique. After the diversion procedure, a liquid meal increased acid secretion from 0.8 mmol H+/min to 1.48 mmol H+/min (P<0.05, paired t test); there was an associated rise in serum levels of gastrin 120 min after feeding (P<0.001, paired t test). Pancreatic secretion of trypsin decreased from 3.91 IU/min to 2.66 IU/min after bile diversion (P<0.01, paired t test), and the level of CCK was significantly lower 60 min after feeding (P<0.05, paired t test). There was no significant change in the rate of gastric emptying after bile diversion, but the pH of duodenal contents was lower in the later stages of digestion. These changes may explain the reported increase of peptic ulcer after diverting bile from the duodenum, and the procedure should not be considered unless the consequences of acid hypersecretion and pancreatic inhibition have been anticipated.
