Persistent Postprandial Regurgitation vs Rumination in Patients With Refractory Gastroesophageal Reflux Disease Symptoms: Identification of a Distinct Rumination Pattern Using Ambulatory Impedance-pH Monitoring

Abstract

Postprandial rumination is very common in refractory GERD with persistent regurgitation. A simple MII-pH score detects rumination in these patients with high sensitivity and specificity.
