Abstract

Gastric emptying of five liquid meals which differ in their physicochemical properties have been measured in control dogs and dogs that have received a Heinecke-Mikulicz pyloroplasty alone, proximal gastric vagotomy without drainage, selective gastric vagotomy and pyloroplasty and truncal vagotomy and pyloroplasty. The first two phases of emptying have been computed by the method of least squares to obtain a logarithmic-linear pattern and are expressed as relative rates: The initial post-ingestion process is characterized by beta or the average relative rate of emptying in the first ten minutes, the basic or exponential rate as beta and the change in rate from the initial to basic pattern as deltabeta. Each measure of gastric emptying was statistically analyzed to determine specific differences in rates between the operations studied. We confirmed the earlier claims that pyloroplasty alone does not change the emptying rate of liquid meals. Each measure or phase of emptying varies consistently across the operations from meal to meal tested. Initial emptying after all three vagotomies is significantly faster than control with progressive rate increases as proximal gastric vagotomy is compared with selective gastric vagotomy with ...Continue Reading
