Gastric emptying was evaluated in a series of unanesthetized dogs in the intact state, following Finney pyloroplasty, and with the addition of vagotomy. Sodium chromate labeled test meals of glucose, trisodium citrate, and trisodium citrate-fat were used. Finney pyioroplasty resulted in a trend for delayed emptying of fat from the stomach. The trisodium citrate test meal increased the levels of gastric secretion after pyloroplasty. Association of our previous motility data based on pyioroplasty studies with the current gastric-emptying evaluations indicate that too large a stoma between the antrum and duodenum is an impediment to normal gastric emptying of fatty meals.
