[Stomach movement following selective gastric vagotomy: correlation of roentgen contrast studies and electromyography in the conscious dog].
Electrical gastric activity in the alert dog was continuously registered by bipolar steel electrodes simultaneously with contrast x-ray studies. Delayed gastric emptying in the postoperative period following selective gastric vagotomy and pyloroplasty can be attributed to specific changes of electrical activity: 1. Electrical potential units become irregular in amplitude and frequency; 2. electrical activity of antrum is no longer synchronized with the corpus; 3. appearance of high frequency, atypical electrical activity in the antrum is associated with gastric motor inactivity; 4. peristalsis and emptying are linked to the de novo appearance of action-potential bursts.
