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.
