Altered pancreatic function after proximal gastric vagotomy in man.

The secretion of bicarbonate into the duodenum in response to stepwise increasing doses of secretin (0.078, 0.23, 0.7, and 2.1 U/kg-hr) was investigated in 11 duodenal ulcer patients before and about 1 1/2 years after proximal gastric vagotomy. After the vagotomy the mean output of bicarbonate in response to the two lowest doses of secretin increased from 2.2 to 3.7 mmoles per 30 min im response to 0.078 U/kg-hr and from 6.6 to 9.8 mmoles per 30 min in response to 0.23 U/kg-hr. On the other hand, the output of bicarbonate in response to the highest dose of secretin decreased from 20.3 mmoles per 30 min before to 16.5 mmoles per 30 min after the vagotomy. The dose of secretin required for half-maximal stimulation decreased from 0.7 to 0.3 U/kg-hr. The calculated maximal bicarbonate response decreased from 27.8 to 17.7 mmoles per 30 min. Thus, increased sensitivity of the bicarbonate-producing cells to low doses of secretin and decreased bicarbonate secretory capacity of the pancreas after proximal gastric vagotomy were found.[1]
