Anastomosis gastric wall was stiff, and peristaltic wave disappeared. 吻合处胃壁僵直,蠕动波消失。
From Child grade A to C, onset peristaltic wave velocity in upper esophageal body became slower, peristaltic contraction reduced, and abnormal contraction increased; 肝硬化组食管上段蠕动波起始点速度变慢,蠕动性收缩减少,异常收缩增加;
From Child grade A to C, peristaltic wave amplitude reduced in lower esophageal body, and velocity of onset peristaltic wave velocity became slower, peristaltic contraction reduced, and abnormal contraction increased. 肝硬化肝功能A~C级各组食管体部下段蠕动压力幅值依次降低,蠕动波起始点速度变慢,蠕动性收缩减少,异常收缩增加。
For Newtonian fluid, the peristaltic flow is determined only by wave amplitude and pressure difference. 鉴于牛顿流体,此时的流动只与波幅和压力差有关。
