Abstract
Postprandial impedance-manometry monitoring improves diagnosis of rumination because it allows distinction between rumination and postprandial belching and regurgitation. During rumination, oesophageal liquid retrograde flow is first driven by an early small rise in intragastric pressure preceding the peak pressure observed during straining.
