Intrinsic emptying pattern of the human stomach

Abstract

Twenty-three subjects were given a total of 336 meals of 750 ml saline that was recovered at 5, 10, and 20 min to determine the intrinsic gastric emptying pattern. Minimal slowing of gastric emptying by duodenal receptors resulted from 120 mM NaCl. Analysis of the residuals from the within-subject regressions for every subject's remaining volume vs. time showed that the exponential model of gastric emptying most appropriately described the data when the volume instilled at time 0 was included.
