摘要

在发生单纯性小肠阻塞后,用机电记录装置长期准备的小马的整个胃肠道中可见特征性的运动模式。胃有液体的明显膨胀导致胃收缩活动丧失,电图混乱。当胃减压时,这些变化立即逆转。在梗阻近端的空肠中,观察到独特的“绞痛运动复合体”,其收缩时间更长,排列在特征的活动脉冲中。左背结肠持续活跃,小结肠保持活跃。继发于小肠梗阻的异常运动模式可能在小肠和大肠疾病的病因学中起作用。

Observations on the colic motor complex in a pony with a small intestinal obstruction.

Characteristic motility patterns were seen throughout the gastrointestinal tract in a pony prepared chronically with electromechanical recording devices after developing a simple obstruction of the small intestine. Gross distension of the stomach with fluid produced loss of gastric contractile activity and a chaotic electrogram. These changes were reversed instantaneously when the stomach was decompressed. In the jejunum, proximal to the obstruction, the unique 'colic motor complex' was observed with contractions of longer duration arranged in characteristic pulses of activity. The left dorsal colon showed continuous hyperactivity and the small colon remained active. Abnormal motility patterns occurring secondary to a small intestinal obstruction could play a role in the aetiology of small and large intestinal disorders.
