食管运动异常如贲门失弛缓症、弥漫性食管痉挛及有关运动失调疾病引起的功能性咽下困难的病员存在着非推进性或同步收缩,本实验设计目的在于研究吞咽引起的或缺乏共同腔自发的同步收缩发病机理。 材料与方法:20例非心源性胸痛,食管运动正常、激发试验阴性的病人为对照。50名功能性咽下困难病员按主要的测压异常分为3组:A组26例,所有吞咽引起的收缩在食管远侧10cm(平滑肌段)都是同步的, Esophageal motility disorders such as achalasia, diffuse esophageal spasm and dysphagia caused by functional dysphagia in patients with non-propulsive or systolic contraction, the purpose of this experiment is to study the swallow induced or lack of common cavity spontaneous Synchronous shrinkage pathogenesis. Materials and Methods: Twenty patients with non-cardiac chest pain, normal esophageal motility, and negative provocation test were used as controls. Fifty functional dysphagia patients were divided into 3 groups according to the main manometry abnormalities: group A, 26 cases, all swallow induced contraction was 10 cm distal to the esophagus (smooth muscle segment) were synchronized,
