Gastric evacuation of low, medium, and high viscosity meals was measured via a duodenal cannula and observed simultaneously by radiography. Computer analysis of the propagation of the gastric waves revealed increased velocity in the distal antrum but no simultaneous contractions of the terminal antrum and pyloric sphincter. Radiography showed, and measurements of the antral diameter confirmed, that the indentations of the gastric waves were significantly deeper with the low viscosity liquid meal compared with the medium and high viscosity meals. Thereby, retropulsion of the medium and high viscosity ingesta was produced. Results indicated that gastric evacuation was regulated predominantly by the depth of the peristaltic indentation, which depended on the viscosity of the gastric contents. Nothing indicated that the phasic contractions of the pyloric sphincter were of importance for the regulation of gastric emptying.<\/jats:p>","DOI":"10.1136\/gut.23.2.150","type":"journal-article","created":{"date-parts":[[2007,9,7]],"date-time":"2007-09-07T21:40:01Z","timestamp":1189201201000},"page":"150-156","source":"Crossref","is-referenced-by-count":82,"title":["Motor function of gastric antrum and pylorus for evacuation of low and high viscosity meals in dogs."],"prefix":"10.1136","volume":"23","author":[{"given":"J","family":"Pr\u00f6ve","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H J","family":"Ehrlein","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1982,2,1]]},"reference":[{"key":"ref_1","series-title":"Proceedings of the fifth international symposium on gastro-intestinal motility","first-page":"284","article-title":"Gastric motility and emptying in rabbits","author":"Ehrlein, H.J.","year":"1975","unstructured":"Ehrlein HJ.
