Duodenojejunal Motility After Oral and Enteral Nutrition in Humans: A Comparative Study

Abstract

EN interrupts PIIIs, but, in most cases, PIIIs reappear before the end of EN. During the interruption of PIIIs, the organization of the contractions is qualitatively different from the fed pattern observed after oral feeding. For the same caloric value of the meal, the quantitative duodenojejunal motor response is not affected by the infusion rate, and the more important jejunal, rather than duodenal motor response found after an oral meal, is observed during EN. During EN, after the return of PIIIs, despite the persistence of a nutrient infusion into the duodenum, the small bowel motor patterns are not qualitatively or quantitatively different from those recorded in fasting subjects.
