The function of the antro-duodenal segment depends on the spatial and temporal sequence of contractions. This process can be defined as antroduodenal coordination. There is no constantly increased pressure in the antro-duodenal transition zone. During the interdigestive phase a coordination of gastral and duodenal motility, gastric acid secretion and bile-flow into the duodenum can be demonstrated. During phase II of the interdigestive phase a pressure gradient, proximal and distal, is observed in the gastroduodenal transition zone with peak values in the pyloric and duodenal bulb area. Cisapride and metoclopramide stimulate antral and duodenal motility, cisapride causes a significant increase in gastroduodenal coordination.
胃十二指肠段的功能取决于收缩的空间和时间顺序。这一过程可被定义为胃十二指肠协调。胃十二指肠过渡区不存在持续升高的压力。在消化间期，可证明胃和十二指肠运动、胃酸分泌以及胆汁流入十二指肠之间存在协调。在消化间期的第二阶段，在胃十二指肠过渡区观察到近端和远端的压力梯度，在幽门和十二指肠球部区域出现峰值。西沙必利和甲氧氯普胺可刺激胃窦和十二指肠的运动，西沙必利可显著增强胃十二指肠的协调性。
