蠕动波

吻合处胃壁僵直，蠕动波消失。

Anastomosis gastric wall was stiff , and peristaltic wave disappeared .

钡剂通过迟缓7例，有逆蠕动波7例，1例自然状态下不排空。

Case appeared barium pass through slowly , 7 case had antiperistalsis wave ;

蠕动波振幅无明显改变（P>0.05）。

While amplitude of phasic contraction in pancreatitis group did not significantly change ( P > ( 0.05 )) .

直肠缩短，肠壁的蠕动波将肠腔内的粪质推入肛管，肛门部有内括约肌及外括约肌，用以阻留或排出粪便。

The rectum shortens , pushing the feces into the anal canal , where internal and external sphincters allow them to be passed or retained .

结果贲门失弛缓症组食管体部均为同步蠕动波，914%（32/35）为低幅同步收缩波；

Results The motor pattern of esophageal body of achalasia was aperistalsis , with 91.4 % ( 32 / 35 ) with low amplitude contraction wave .

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 , onset peristaltic wave velocity in upper esophageal body became slower , peristaltic contraction reduced , and abnormal contraction increased ;

肝硬化门脉高压症合并食管静脉曲张破裂出血，硬化剂注射治疗后食管运动功能减弱，蠕动波数目减少，并诱发同时性收缩及双相收缩等异常收缩，食管酸清除率下降。

Sclerotherapy for esophageal varices can have impact on esophageal motility , reduce the number of peristaltic waves , induce simultaneous contractions and biphasic contractions , and decrease acid clearence .

结果X线钡餐检查发现术后两组患者及犬的胃和十二指肠形态正常，胃蠕动波清晰可见。

Results It was found by barium meal examinations that the shape of the stomach and duodenum was normal and gastric peristalsis was clearly visible in all the animals and patients of two postoperative groups .

记录的波形作频谱分析，报告胃运动的频率与强度，并判断胃蠕动波的移行方向与速度。

The waveform recorded can be analyzed by power spectrum analysis , and the equipment can get data of the frequency and intensity of stomach motility , and estimates the migrating direction and speed of stomach peristalsis .

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。

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 .
