Abstract
BACKGROUND Belching disorders and rumination syndrome (RS) are disorders of gut-brain interaction (DGBIs) in Rome IV. Belching disorders are composed of excessive gastric belching (GB) and supragastric belching (SGB). Excessive GB is related to physiological phenomenon whereas excessive SGB and RS are behavioral disorders. SUMMARY A recent large internet survey found that prevalence of belching disorders and RS were 1% and 2.8%, respectively. It has been recognized that not a few patients with two behavioral disorders, excessive SGB and RS, could be misdiagnosed as proton pump inhibitors (PPI)-refractory gastroesophageal reflux disease (GERD). In patients with reflux symptoms, distinguishing these conditions is essential because they need psychological treatment (i.e., cognitive behavioral therapy (CBT) rather than acid suppressants. Clinicians should take a medical history meticulously first to identify possible excessive SGB and/or RS. High-resolution impedance manometry and/or 24-h impedance-pH monitoring can offer an objective diagnosis of the disorders. Several therapeutic options are available for excessive SGB and RS. The first-line therapy should be CBT using diaphragmatic breathing that can stop the behaviors involving complex muscle contraction (e.g., abdominal straining) to generate SGB or rumination. Overlap with eating disorders and/or other DGBIs such as functional dyspepsia can make management of the behavioral disorders challenging since such coexisting conditions often require additional treatments. KEY MESSAGES Excessive SGB and RS are not unusual conditions. It is important to raise awareness of the behavioral disorders for appropriate management.

Abstract
PURPOSE OF REVIEW Rumination syndrome (RS) is a functional gastroduodenal disorder characterized by repeated effortless regurgitation or vomiting of recently ingested food without retching. RS generally has been considered a rare entity. However, it has been increasingly recognized that many RS patients are likely to be underdiagnosed. This review discusses how to recognize and manage RS patients in clinical practice. RECENT FINDINGS A recent epidemiological study that included over 50,000 individuals found that the prevalence of RS around the world is 3.1%. In patients with proton pump inhibitor (PPI)-refractory reflux symptoms, postprandial high-resolution manometry combined with impedance (HRM/Z) reveals that RS accounts for up to 20% of those cases. HRM/Z can be a gold standard for objective RS diagnosis. In addition, off-PPI 24-h impedance pH monitoring can suggest the possibility of RS when it reveals frequent postprandial, non-acid reflux with a high symptom index. Modulated cognitive behavioral therapy (CBT) targeting secondary psychological maintaining mechanisms almost eliminates regurgitation. SUMMARY The prevalence of RS is higher than generally thought. For patients suspected of RS, HRM/Z is useful to distinguish RS from gastroesophageal reflux disease. CBT can be a highly effective therapeutic option.

Abstract
With the advent of high-resolution esophageal manometry, it is recognized that the antireflux barrier receives a contribution from both the lower esophageal sphincter (intrinsic sphincter) and the muscle of the crural diaphragm (extrinsic sphincter). Further, an increased intra-abdominal pressure is a major force responsible for an adaptive response of a competent sphincter or the disruption of the esophagogastric junction resulting in gastroesophageal reflux, especially in the presence of a hiatal hernia. This review describes how the pressure dynamics in the lower esophageal sphincter were discovered and measured over time and how this has influenced the development of antireflux surgery.

Abstract
BACKGROUND & AIMS Rumination syndrome is a Disorder of Gut-Brain Interaction (DGBI) of unknown etiology. We aimed to assess its global prevalence and potential associations with other medical conditions. METHODS Data were collected via the Internet in 26 countries. Subjects were evenly distributed by country, sex, and age groups and were invited for a "health survey" using the Rome IV diagnostic questionnaire and a supplementary questionnaire addressing factors potentially associated with DGBI. RESULTS In all, 54,127 subjects completed the survey (51% male; mean age, 44.3 years). The overall prevalence of rumination syndrome was 3.1% (95% confidence interval [CI], 3.0-3.3%). It was highest in Brazil (5.5% CI, 4.5-6.5) and lowest in Singapore (1.7% CI, 1.1-2.2). The mean age of people with rumination syndrome was 44.5 years (standard deviation, 15.6) and it was more common in females (54.5% vs 45.5%). Factors independently associated with rumination syndrome were depression (odds ratio [OR], 1.46), anxiety (OR, 1.8), body mass index (OR, 1.04), and female sex (OR, 1.19). Subjects with multiple DGBI were at increased risk of having rumination syndrome, with the highest risk in subjects with 4 gastrointestinal regions with DGBI (OR, 15.9 compared with none). Quality of life (QoL) was lower in subjects with rumination syndrome compared with the rest of the cohort (PROMIS-10 score: physical QoL mean 12.9 vs 14.5; mental QoL mean 12.0 vs 13.6). CONCLUSIONS The prevalence of rumination syndrome is higher than reported in most previous population studies and is likely underdiagnosed in clinical practice. Awareness of rumination syndrome should be raised among clinicians to improve care for these patients.
