title: Antral vagotomy in parietal cell vagotomized dogs with a Heineke-Mikulicz pyloroplasty. Effect upon gastric emptying and motility, serum gastrin concentration, and Heidenhain pouch acid secretion.
abstract: In 6 Heidenhain pouch (HP) dogs who previously had undergone parietal cell vagotomy (PCV) with a Heineke-Mikulicz pyloroplasty (Ppl), the antral nerves were cut. No significant changes in HP acid secretion or serum gastrin concentration occurred. In a similar previous study using HP dogs with a PCV and a gastroduodenostomy (GD), a significant rise in HP acid secretion without concomitant changes in serum gastrin concentration were observed after antral denervation. These findings indicate that the antral vagal nerves have no direct influence on HP acid secretion, but the rised HP acid secretion in the GD dogs after antral denervation may be related to the changed gastroduodenal emptying pattern which partly excludes the food acid stream from the acid inhibitory mechanism in the duodenal bulb.
