消化性溃疡(Peptic Ulcer,PU)是胃、十二指肠粘膜的损害因子和保护因子失衡的结果,其发病机理较复杂。由于胃肠运动研究的深入,人们已对PU的胃肠动力改变产生很大的兴趣。本文复习文献,重点是PU是否存在运动异常,运动改变在溃疡病发生中的作用以及研究PU运动异常的病理的意义。一、胃十二指肠的运动生理和研究方法空腹时,胃十二指肠的运动呈周期性,其生理基础为胃肠肌电。胃肌电起博点位于胃体上部大弯侧,肠肌电起博点位于幽门下1cm处。胃肠肌电自胃向下传递,可达到回肠。空腹时胃肠肌电的慢波加上动作电位,可产生机械性收缩,称为消化间期的运动复合波(Interdigestive motor complex, IDMC)。IDMC分为四期,Ⅰ期为静止期,
Peptic ulcer (PU) is a result of imbalance between protective and damaging factors in gastric and duodenal mucosa. Its pathogenesis is complicated. Due to the study of gastrointestinal motility, there has been great interest in the gastrointestinal motility of PU. This article reviews the literature, focusing on whether there is abnormal PU movement, exercise changes in the role of ulcer disease and study the significance of PU pathological abnormalities. First, the stomach and duodenum, exercise physiology and research methods fasting, gastroduodenal movement was periodic, and its physiological basis for gastrointestinal myoelectrical. Gastric electromyography Pok Bo points located in the upper part of the stomach curvature side, intestinal myoelectricity Bo point located in the pylorus 1cm Department. Gastrointestinal electromyogram down from the stomach, can reach the ileum. Fasting gastrointestinal EMG slow wave plus action potential, can produce mechanical contraction, called the interdigestive motor complex (Interdigestive motor complex, IDMC). IDMC is divided into four phases, stage I is quiescent,
