Figure 5. — Compensatory increase in antral motility in response to elevated integrated relaxation pressure. (A) An elevated esophagogastric junctional outflow resistance as measured by the integrated relaxation pressure (blue arrows) may interfere with retrograde venting and belching resulting in in increased intragastric pressure (orange arrows). (B) The stomach becomes distended and compensatory increase in antral motility (black arrows) is proposed to develop as a means of enhancing gastric emptying in these patients.
