The rumination syndrome in adults. A characteristic manometric pattern
Annals of Internal Medicine
|October 1, 1986
Summary
Rumination syndrome involves chewing regurgitated food. Esophageal and gastrointestinal motility studies revealed a characteristic pressure spike-wave pattern in patients with this condition.
Area of Science:
- Gastroenterology
- Digestive System Disorders
- Clinical Medicine
Background:
- Rumination syndrome is characterized by regurgitation and re-chewing of gastric contents.
- It often presents as long-standing postprandial vomiting in adults.
- Differential diagnosis is crucial for effective management.
Purpose of the Study:
- To investigate the clinical and manometric characteristics of rumination syndrome.
- To support the diagnosis of rumination syndrome with objective motility studies.
- To explore potential contributing factors, including psychological disturbances.
Main Methods:
- Case series of 12 patients diagnosed with rumination syndrome.
- Esophageal and gastrointestinal motility studies (manometry) were performed.
- Psychological assessment using the Minnesota Multiphasic Personality Inventory (MMPI).
Main Results:
- A characteristic pressure spike-wave pattern was observed during regurgitation in all patients.
- This pattern showed increased frequency and amplitude postprandially.
- Patients exhibited normal underlying gastrointestinal motility with a slight decrease in antral motility.
- Significant personality disturbances were noted in nine patients, with elevated scores for hypochondriasis and depression.
Conclusions:
- The manometric pressure spike-wave pattern is a characteristic finding supporting the diagnosis of rumination syndrome.
- Rumination syndrome should be considered in adult patients presenting with chronic postprandial vomiting.
- Psychological factors may play a role in the development or manifestation of rumination syndrome.

01:26Respiratory Volumes and Capacities I
Assessing the respiratory rate and rhythm for a complete minute is crucial for evaluating the breathing pattern. Even a minor increase in the patient's average respiratory rate, by as little as three to five breaths per minute, is an early and vital indicator of respiratory distress. Patients with a respiratory rate exceeding twenty-four breaths per minute require close monitoring to determine the physiological alterations. This careful observation is essential for prompt recognition and...
01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

01:30Alterations in Respiration II
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...

01:27Physical Assessment of the Respiratory Tract II: Inspection
Physical assessment of the respiratory tract through inspection is a crucial step in understanding the patient's respiratory health. It provides insights into the functioning of the respiratory system, the musculoskeletal structure, and even the patient's nutritional status. This comprehensive approach involves observing several vital aspects: chest configuration, breathing patterns, respiratory rates, skin color, and use of accessory muscles.
