Background/Aims: Our aim was to study the effect of the viscosity of enteral nutrient solutions on upper gut motility and gut hormone secretion. Methodology: We used 5 beagle dogs equipped with strain gauge force transducers to measure upper gastrointestinal motility. Upper gut motility and gut hormone secretion were compared across 6 experimental conditions; control (oral solid meal), liquid-120, liquid-5 (liquid enteral nutrients administered for 120 and 5min, respectively), low, middle, and high viscosity conditions. Results: The magnitude of receptive relaxation was decreased in the liquid-120 compared to control, but this decrease was reversed with the increase of viscosity. The duration of the postprandial contractions in the proximal jejunum was decreased in the liquid-5 compared to the control, but this decrease was reversed in the middle and high viscosity conditions (p<0.05). Rapid increase in plasma concentrations of gastric inhibitory polypeptide observed in the liquid-5 compared to the control was reversed in the low, middle, and high viscosity conditions. Conclusions: Although patterns of upper gut motility and gut hormone secretion after liquid enteral nutrients were considerably altered compared to those after solid meal ingestion, increasing the viscosity of liquid enteral nutrients reversed those altered patterns.
