Peristaltic Wave in the Antrum
Peristaltic Wave
The gastric motility is regulated by a gastric "pacemaker". Many gastrointestinal hormones influence the motility.
Peristaltic Wave
During endoscopy at least one peristaltic wave in the antrum is followed. If the motility of the wall is defect, this may indicate e.g. tumous infiltration. In these pictures, a normal peristaltic wave is seen.
Peristaltic Wave
Sometime the peristalsis does not "start" during endoscopy. Suctioning of all the air in the stomach, and then filling the stomach with air usually cause a peristaltic wave.
