Abnormal Duodenal Loop: Influence on Basal and Food-stimulated Motility Pattern

Abstract

Basal and food-stimulated motility patterns were studied in seven patients with distal duodenal anomalies (DDA) and in seven controls. A discordant pressure pattern and a significantly higher frequency of pressure waves was observed in DDA both in the basal state and after food intake in comparison to controls. It is concluded that the shape of the duodenal loop can influence basal and food-stimulated motility patterns in the duodenum, and thereby probably also the transport mechanism through the duodenal loop.
