Comparison of the effect of conventional highly selective vagotomy and anterior gastric wall stapling with posterior truncal vagotomy on the gastric emptying rate for solid meals in beagle dogs.

Anterior gastric wall stapling combined with posterior truncal vagotomy has been used as a new and adequate gastric acid output-reducing procedure. Severing the posterior vagal trunk as well as stapling the anterior gastric wall could impair gastric emptying. In this study, the gastric emptying rate for solid food, using a radionuclide technique, has been evaluated in 2 series of canine experiments. Compared to the results after conventional highly selective vagotomy, a temporary delay in the gastric emptying rate could be found after this new procedure, however, completely normalizing 1 year later.
