Area of Science:

  • Gastroenterology
  • Functional Gastrointestinal Disorders

Background:

  • Rumination syndrome is a functional gastrointestinal disorder.
  • Characterized by effortless postprandial regurgitation of ingested food.
  • Estimated prevalence is 2% in the general adult population.

Purpose of the Study:

  • To describe the key mechanisms, clinical characteristics, diagnosis, and management of rumination syndrome.

Main Methods:

  • Clinical diagnosis based on established criteria.
  • High-resolution esophageal manometry with impedance monitoring as an adjunct.
  • Assessment of psychiatric comorbidity.

Main Results:

  • Key mechanism involves unperceived postprandial abdominal wall contraction leading to retrograde flow.
  • Clinical characteristics include early postprandial regurgitation of food-like material.
  • Management involves patient education, diaphragmatic breathing, and addressing psychiatric issues.

Conclusions:

  • Rumination syndrome is a distinct functional gastrointestinal disorder.
  • Diagnosis is primarily clinical, supported by manometry.
  • Management focuses on behavioral interventions and addressing comorbidities, with medication as a second-line option.
