[Animal experiments of emptying and reflux response to terminolateral gastroduodenostomy]

The reflux and emptying mechanisms of the terminolateral gastroduodenostomy after two-thirds gastrectomy was examined in dogs. Intraluminal pressure in the gastric remnant and proximal duodenum as well as cineradiographic examinations showed that the anastomosis behaves like the intact stomach. The duodenal segment which regulates gastric emptying prevents reflux into the gastric remnant by means of rising pressure.
