Summary

Gastroesophageal reflux disease (GERD) is a motility disorder where acid suppression offers only symptomatic relief. This review explores additional factors beyond acid reflux impacting GERD pathogenesis and treatment efficacy.

Esophageal function tests are not helpful in symptoms suspicious of extraesophageal reflux - a prospective study in 74 patients.

Zeitschrift fur Gastroenterologie·2016

Area of Science:

  • Gastroenterology
  • Esophageal Motility Disorders
  • Acid Reflux Disease

Context:

  • Gastroesophageal reflux disease (GERD) is primarily treated with acid suppression, yet recurrence rates exceed 90% upon discontinuation.
  • A significant therapeutic challenge arises in patients with therapy-resistant GERD, high proton pump inhibitor (PPI) dosage requirements, or significant volume reflux.

Purpose:

  • To analyze factors beyond acid suppression contributing to GERD pathogenesis and treatment interpretation.
  • To discuss the role of gastroesophageal motility, esophageal barrier function, duodenogastroesophageal reflux, and Helicobacter pylori infection.

Summary:

  • GERD's motility disorder nature suggests limitations of purely acid-reducing therapies.
  • Additional contributing factors include impaired esophageal motility, compromised barrier function, and bile reflux.
  • The study also examines challenges in assessing treatment success, including placebo effects and subjective symptom interpretation.

Impact:

  • Highlights the need for a multifactorial approach to GERD management beyond simple acid reduction.
  • Provides insights into understanding and addressing therapeutic resistance in GERD patients.
  • Emphasizes the complexity of GERD, involving motility, barrier function, and subjective patient experience.
