Core Tip
Core tip: Intra-gastric infusion of short-chain triglycerides, such as triacetin, has been shown to delay gastric emptying in conscious dogs, but the influence on upper gastrointestinal motility is unknown. The current study examined time-dependent changes in motility following intra-gastric triacetin administration at various doses in conscious dogs and evaluated the effects of a fasted vs fed state. Compared to infusion of water (vehicle) alone, the 1.0% and 2.0% triacetin doses induced a significant increase in the proximal stomach receptive volume, a temporary inhibition of gastric antral contractions, and an increase in the duodenal contractions in fasted dogs.
