Abstract

The purpose of this study was to examine the existence of a lag phase of gastric emptying of solid meals. We studied solid phase gastric emptying in 26 normal subject using continuous data aquisition for 30 minutes. Each ingested a 300 g meal containing $^{99m}Tc-labeled$ scrambled egg (solid 150g, milk 150 ml). Lag phase was determined by 1) inspection of the gastric emptying curve 2) time to a 2% decrease in stomach activity 3) the time of visual appearance of duodenal activity on computer image We concluded that solid meal lag phase exist.
