Gastric reflux measurements during duodenal infusion with saline, acid and fat.
Duodeno-gastric reflux measured in 18 patients without gastrointestinal complaints showed a wide variation of regurgitation rates. Duodeno-gastric reflux was significantly diminished during duodenal acidification. The effect was more intense and lasted longer after olive oil infused intraduodenally, leading practically to a closed pylorus.
