Rumination is thought to occur due to a reversal of the esophagogastric pressure gradient. This is achieved by a coordinated abdominothoracic maneuver consisting of a thoracic suction, crural diaphragm relaxation and an increase in intragastric pressure. Careful history is important in the diagnosis of rumination syndrome; patients often report \u201cvomiting\u201d or \u201creflux\u201d and the diagnosis can therefore be missed. Objective testing is available with high resolution manometry or gastroduodenal manometry. Increase in intra\u2010gastric pressure followed by regurgitation is the most important characteristic to distinguish rumination from other disorders such as gastroesophageal reflux. The mainstay of the treatment of rumination syndrome is behavioral therapy via diaphragmatic breathing in addition to patient education and reassurance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Purpose<\/jats:title><jats:p>The purpose of this review was to critically appraise recent key developments in the pathophysiology, diagnosis and therapy for rumination syndrome.
