在胃肠病学中,关于胃复杂的运动了解得很少。原因之一是缺乏简单的方法测定胃的运动功能,更重要的可能是究竟运动功能的哪一方面与临床表现有关尚很不肯定。近10年来对胃运动、胃排空生理的认识有相当的进展,讨论这些知识及其临床意义是适时的。正常胃的排空正常进食后,由于胃底及上部胃体的松弛,食物容受于胃内,此松弛作用系由吞咽动作及近端胃的扩张所激发,主要通过迷走神经,特别
In gastroenterology, little is known about gastric intricacies. One of the reasons is the lack of an easy way to measure gastric motor function, and more importantly, to what extent the motor function is related to the clinical manifestations is still not sure. In the past 10 years, considerable progress has been made in the understanding of gastric motility and gastric emptying physiology. It is timely to discuss these knowledge and its clinical significance. Normal gastric emptying Normal eating, due to the relaxation of the stomach fundus and upper body of the stomach, the food content in the stomach, the relaxation of the swallowing action by the proximal stomach and the expansion of the excited, mainly through the vagus nerve, especially
