Manometric study of a ruminator.

R P Reynolds, D A Lloyd

Journal of Clinical Gastroenterology

|April 1, 1986

Summary

This summary is machine-generated.

Rumination regurgitation is triggered by a Mueller maneuver, a forced inspiration against a closed glottis. This study found no intrinsic motility abnormalities in this classic ruminator.

Area of Science:

Gastroenterology
Physiology

Background:

Rumination disorder presents with controversial pathophysiology.
Understanding the mechanisms of voluntary regurgitation is crucial.

Observation:

A classic ruminator underwent esophageal, gastric, and small bowel motility studies during voluntary regurgitation.
Regurgitation involved simultaneous positive pressure in the stomach and negative pressure in the esophagus.
Brief lower esophageal sphincter relaxation and deep inspiratory efforts were noted.

Findings:

No intrinsic abnormalities in esophageal, gastric, or small bowel motility were detected.
Regurgitation correlated with a Mueller maneuver (forced inspiration against a closed glottis).

Implications:

Related Experiment Videos

The findings suggest a specific trigger for regurgitation in ruminators.
This provides insight into the pathophysiology of rumination disorder.
Further research can explore therapeutic strategies targeting this mechanism.
