Abstract
No change was observed in fasting Heidenhain pouch (HP) acid secretion and fasting serum gastrin concentration following parietal cell vagotomy (PCV) in six dogs whereas significant increase in food-stimulated pouch secretion and serum gastrin concentration was observed. The increase in pouch secretion after PCV took place mainly in the first 2 h after meal. The maximum serum gastrin concentration was reached at 15 min after feeding before as well as after PCV. Maximum in HP secretion was reached later, at 120 min before and at 90 min after surgery. Gastric emptying studies, using a food-barium meal, showed a slight decrease in the emptying rate after PCV in two dogs, while it was unchanged in the others. Cineradiography showed an unaffected antral motility in all dogs after PCV.
