Abstract
Belching is the act of expelling air from the stomach or esophagus into the pharynx. Although the process is regarded as physiological, excessive belching might be associated with a significant burden for affected patients in the sense of a belching disorder. Diagnosis of a belching disorder is often challenging, and its differentiation from other conditions such as rumination syndrome, singultus, or aerophagia can be difficult. Treatment of these disorders also represents a challenge for otorhinolaryngologists. Hence, the aim of this review is to provide an interdisciplinary overview of these clinical syndromes and provide practical guidance for their diagnosis and treatment.

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
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.

Abstract
BACKGROUND Rumination syndrome is a functional gastroduodenal disorder characterised by effortless regurgitation of recently ingested food. Emerging evidence reports duodenal eosinophilic inflammation in a subset, suggesting a shared pathophysiology with functional dyspepsia (FD). AIM To assess the clinical features of rumination syndrome and FD in a community-based study. METHODS We mailed a survey assessing gastrointestinal symptoms, diet and psychological symptoms to 9835 residents of Olmsted County, MN, USA in 2017-2018; diagnostic codes were obtained from linked clinical records. The two disorders were assessed as mutually exclusive in 'pure' forms with a separate overlap group, all compared to a control group not meeting criteria for either. Prevalence of associations, and univariate and independent associations with predictors were assessed by logistic regression. RESULTS Prevalence of rumination syndrome and FD were 5.8% and 7.1%, respectively; the overlap was 3.83-times more likely than expected by chance. Independent predictors for rumination (odds ratio (OR), 95% confidence interval (CI)) were female gender (1.79, 1.21-2.63), smoking (1.89, 1.28-2.78), gluten-free diet (1.58, 1.14-2.19), allergic rhinitis (1.45, 1.01-2.08) and depression (1.10, 1.05-1.16). FD was independently associated with female gender, depression, non-coeliac wheat sensitivity, migraine, irritable bowel syndrome and somatic symptoms. A similar reported efficacy (≥54%) of low fat or dairy-free diets was found with both disorders (P = 0.53 and P = 1.00, respectively). The strongest independent associations with overlapping FD and rumination syndrome were a history of rheumatoid arthritis (3.93, 1.28-12.06) and asthma (3.02, 1.44-6.34). CONCLUSION Rumination syndrome overlaps with FD with a shared risk factor profile, suggesting a common pathophysiology.

Abstract
Rumination syndrome is a functional disorder characterized by the involuntary regurgitation of recently swallowed food from the stomach into the mouth, from where it can be re-chewed or expelled. Clinically, it is characterized by repeated episodes of effortless food regurgitation. The most usual complaint is frequent vomiting. The physical mechanism that generates regurgitation events is dependent on an involuntary process that alters abdominal and thoracic pressures accompanied by a permissive oesophageal-gastric junction. The diagnosis of rumination syndrome is clinical, highlighting the importance of performing an exhaustive anamnesis on the characteristics of the symptoms. Complementary tests are used to corroborate the diagnosis or rule out organic pathology. Treatment is focused on behavioural therapies as the first line, reserving pharmacological and surgical therapies for refractory cases.

Abstract
PURPOSE OF REVIEW Rumination syndrome is a gastrointestinal disorder characterized by effortless regurgitation of recently ingested food. The disorder is rare, but likely under-recognized and leads to impaired quality of life among those affected. This review discusses recent studies which examined the pathophysiology, diagnoses and therapy of rumination syndrome. RECENT FINDINGS The pathogenesis of rumination syndrome remains incompletely understood. Therapeutic options, which appear effective, include behavioral therapy with diaphragmatic breathing and pharmacotherapy with baclofen. A randomized trial of behavioral therapy, biofeedback therapy led to a 74% + /- 6% reduction in rumination activity (from 29 + /- 6 before to 7 + /- 2 daily events after intervention) vs. 1% + /- 14% during sham (from 21 + /- 2 before to 21 + /- 4 daily events after intervention) (P = .001). A recent randomized trial of baclofen at a dose of 10 mg three times daily led to symptomatic improvement in 63% of patients with rumination syndrome. SUMMARY This review summarizes a clinical approach to diagnosing and treating rumination syndrome. Behavioral therapy consisting of diaphragmatic breathing, with or without biofeedback, remains the most effective treatment strategy for patients with rumination syndrome.

Abstract
BACKGROUND Rumination syndrome (RS) is characterized by recurrent effortless postprandial regurgitation of recently ingested food from the stomach to the oral cavity and has been associated with quality of life impairment and malnutrition. There is a general lack of consensus on the most appropriate treatment options for RS.
AIM To summarize the literature on treatment options for RS.
METHODS We conducted a systematic review according to PRISMA guidelines. We searched Medline (1946 to February 2019), EMBASE (1947 to February 2019), PsycINFO (1806 to February 2019) and Cochrane central register of controlled trials for articles discussing treatment options for adult patients (> 18 years) with RS. All relevant articles were accessed in full text. We extracted data on study designs, patient profiles, duration of symptoms, follow up periods, date, diagnostic criteria, interventions and outcomes. Risk of bias assessment was carried out independently by 3 reviewers via Cochrane Risk of Bias tool and Newcastle Ottawa Scale for randomized controlled trials and Cohort studies respectively.
RESULTS Twelve articles were identified. A total of 254 patients were included in the analysis, with a mean age of 36.1 (range 18-89). 185 patients (72.8%) were females. 5 studies looked into behavioral therapies, primarily diaphragmatic breathing (DB) 2 studies looked at baclofen, 1 fundoplication and 1 supportive lifestyle changes. 3 studies looked at a combination of therapies involving pharmacological, behavioral and psychotherapies.
CONCLUSION Although evidence for treatment options is still limited, the strongest evidence point towards the use of DB and Baclofen, and both should be considered depending on their availabilities.

Abstract
Rumination syndrome (RS) is characterized by the repeated regurgitation of material during or soon after eating with the subsequent rechewing, reswallowing, or spitting out of the regurgitated material. Rumination syndrome is classified as both a "Functional Gastroduodenal Disorder" (by the Rome Foundation's Functional Gastrointestinal Disorders: Disorders of Gut-Brain Interaction, 4th edition) and a "Feeding and Eating Disorder" (by the Diagnostic and Statistical Manual of Mental Disorders, 5th edition). Rumination syndrome is a disorder that is often inaccurately diagnosed or missed, resulting in patients experiencing protracted symptoms and not receiving treatment for long periods. There is a lack of clear consensus for RS diagnosis, mechanisms that maintain RS, and treatment. Guided by existing research and our clinical expertise, we synthesize available evidence and provide recommendations for clinical use. We present a case example and critically summarize the literature to date to (i) increase clinicians' understanding of heterogeneous clinical presentations, (ii) suggest assessment strategies to facilitate accurate diagnosis, and (iii) provide a schematic for intervention options. Overall, we recommend clinicians recognize the heterogeneous features of RS when considering diagnosis, assess for RS symptoms by clinical history, and treat RS with targeted diaphragmatic breathing while using other methods as augmented intervention or alternative treatment.

Abstract
BACKGROUND & AIMS Recognition of rumination and supragastric belching is often delayed as symptoms may be mistakenly attributed to gastroesophageal reflux disease. However, distinct from gastroesophageal reflux disease, rumination and supragastric belching are more responsive to behavioral interventions than to acid-suppressive and antireflux therapies. Postprandial high-resolution impedance manometry (PP-HRIM) is an efficient method to identify rumination and belches. We investigated the distribution of postprandial profiles determined by PP-HRIM, and identified patient features associated with postprandial profiles among patients with nonresponse to proton pump inhibitors (PPIs). METHODS We performed a retrospective analysis of PP-HRIM studies performed on 94 adults (mean age, 50.6 y; 62% female) evaluated for PPI nonresponsiveness at an esophageal referral center, from January 2010 through May 2016. Following a standard esophageal manometry protocol, patients ingested a solid refluxogenic test meal (identified by patients as one that induces symptoms) with postprandial monitoring up to 90 minutes (median, 50 min). Patients were assigned to 1 of 4 postprandial profiles: normal; reflux only (>6 transient lower esophageal sphincter relaxations (TLESRs)/h); supragastric belch (>2 supragastric belches/h), with or without TLESR; or rumination (≥1 rumination episode/h) with or without TLESR and supragastric belching. The primary outcome was postprandial profile. RESULTS Of the study participants, 24% had a normal postprandial profile, 14% had a reflux-only profile, 42% had a supragastric belch profile, and 20% had a rumination profile. In multinomial regression analysis, the rumination group most frequently presented with regurgitation, the supragastric belch and rumination groups were younger in age, and the reflux-only group had a lower esophagogastric junction contractile integral. The number of weakly acidic reflux events measured by impedance-pH monitoring in patients receiving PPI therapy was significantly associated with frequency of rumination episodes and supragastric belches. CONCLUSIONS In a retrospective analysis of 94 nonresponders to PPI therapy evaluated by PP-HRIM, we detected an abnormal postprandial pattern in 76% of cases: 42% of these were characterized as supragastric belching, 20% as rumination, and 14% as reflux only. Age, esophagogastric junction contractility, impedance-pH profiles, and symptom presentation differed significantly among groups. PP-HRIM can be used in the clinic to evaluate mechanisms of PPI nonresponse.

Abstract
OBJECTIVES Both rumination syndrome and supra-gastric belching (SGB) have limited treatment options. We demonstrated (open-label) that baclofen reduces pressure flow events in these patients. We aimed to study the effect of baclofen in a placebo-controlled, double-blind, cross-over study in patients with clinically suspected rumination and/or SGB. METHODS Twenty tertiary-care patients (mean age 42 years (range 18-61), 13f) with clinically suspected rumination and/or SGB were randomized to receive baclofen (10 mg, t.i.d) or placebo for 2 weeks with cross-over to the alternative intervention after a 1 week wash-out period. At the end of each treatment period, patients underwent a solid-state high-resolution impedance manometry measurement, during which they registered symptoms. Patients received a solid meal and recordings continued for 1 h. They scored overall treatment evaluation (OTE) on a -3 to +3 scale. RESULTS Both the number of regurgitation event markers and rumination episodes were significantly decreased after baclofen (6 (0-19) vs. 4 (0-14), P=0.04; 13 (8-22) vs. 8 (3-11), P=0.004). The number of SGB episodes was similar in both groups. Lower esophageal sphincter (LES) pressure was significantly higher and the number of transient LES relaxations was significantly lower after baclofen (17.8 (12.7-22.7) vs. 13.1 (7.2-16.9) mm Hg, P=0.0002; 4(1-8) vs. 7(3-12), P=0.17). The number of reflux events decreased in the baclofen condition (4 (1-9) vs. 3 (0-6), P=0.03). Straining episodes were similar in both arms, but the rumination/straining ratio was significantly lower in the baclofen arm (0.06 (0-0.32) vs. 0.33 (0-0.51), P=0.0012). OTE was superior after baclofen compared to placebo (P=0.03). CONCLUSIONS Baclofen is an effective treatment option for patients with rumination syndrome, probably through its effect on LES pressure.

Abstract
Rumination syndrome is one of the functional gastroduodenal disorders. Effortless and repetitive regurgitation of recently ingested food from the stomach to the oral cavity followed by rechewing and reswallowing or spitting are the characteristic clinical features. This disorder is believed to be uncommon, but many patients with this disorder are overlooked by their physicians. Rumination might be caused by a reversal of the gastric contents through the esophagogastric junction, which is initiated by an increase in intragastric pressure. The characteristic symptoms are sufficient for the diagnosis of rumination syndrome. Postprandial high resolution esophageal impedance manometry can detect gastric pressurization exceeding 30 mmHg associated with the return of ingested material into the proximal esophagus, which is a pathognomonic finding of rumination syndrome. An extensive explanation of the condition and the underlying mechanism is the first step of the treatment of rumination syndrome. Behavioral therapy through diaphragmatic breathing is the mainstay of treatment. Further studies on the long term effects of biofeedback therapy as well as a proper strategy for refractory rumination syndrome are needed.

Abstract
BACKGROUND Rumination syndrome is a functional gastrointestinal disorder characterized by effortless and repetitive regurgitation of recently ingested food from the stomach to the oral cavity followed by either re-swallowing or spitting. 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 "vomiting" or "reflux" and the diagnosis can therefore be missed. Objective testing is available with high resolution manometry or gastroduodenal manometry. Increase in intra-gastric 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. PURPOSE The purpose of this review was to critically appraise recent key developments in the pathophysiology, diagnosis and therapy for rumination syndrome. A literature search using OVID (Wolters Kluwer Health, New York, NY, USA) to examine the MEDLINE database its inception until May 2016 was performed using the search terms "rumination syndrome," "biofeedback therapy," and "regurgitation." References lists and personal libraries of the authors were used to identify supplemental information. Articles published in English were reviewed in full text. English abstracts were reviewed for all other languages. Priority was given to evidence obtained from randomized controlled trials when possible.

Abstract
Rumination is a normal and common phenomenon among ruminant animals; but in humans, it is always regarded as symptom indicative of abnormal function of the upper gastrointestinal tract, and understanding of the mechanisms explaining this event are still evolving. Learning-based theories, organic factors such as gastroesophageal reflux disease and psychological disturbances (eg, depression, anxiety) and the role of life stresses have been postulated as potential mechanisms of rumination. In this review, we take the approach that rumination syndrome is a distinct and discrete functional gastroduodenal disorder. We review current concepts of the pathophysiology of this entity and diagnostic approaches, then detail the treatment paradigms that have been pursued in rumination syndrome in adults. Patients with rumination syndrome have a very distinct set of symptoms. It was focused on the immediate postprandial period, but recently, there is an awareness of an expanding spectrum of the clinical presentation. This includes the concept of "conditioned vomiting" occurring in the setting of delayed gastric emptying (gastroparesis). Physicians' awareness of rumination syndrome is essential in the diagnosis and management of this disorder. Stress and psychological aspects in rumination syndrome are invariably in the background and have to be addressed. The crucial steps in the treatment strategy for rumination syndrome rely on reassurance, education and a physiologic explanation to the patient and family that this is not a "disease," followed by behavioral and relaxation programs and addressing stress factors.

Abstract
BACKGROUND & AIMS Rumination syndrome is characterized by effortless recurrent regurgitation of recently ingested food into the mouth, with consequent expulsion or re-chewing and swallowing. We investigated whether rumination is under volitional control and can be reversed by behavioral treatment. METHODS We performed a prospective study of 28 patients who fulfilled the Rome criteria for rumination and had no organic disorders on the basis of a thorough evaluation. The diagnosis of rumination was confirmed by intestinal manometry (abdominal compression associated with regurgitation). Patients were trained to modulate abdominothoracic muscle activity under visual control of electromyographic recordings. Recordings were made after challenge meals, before training (baseline), and during 3 treatment sessions. Outcome was measured by questionnaires administered daily for 10 days before training, immediately after training, and at 1, 3, and 6 months after training. RESULTS By the end of the 3 sessions, patients had effectively learned to reduce intercostal activity (by 50% ± 2%; P < .001 vs basal) and anterior wall muscle activity (by 30% ± 6%; P < .001 vs basal). Patients reported 27 ± 1 regurgitation episodes/day at baseline and 8 ± 2 episodes/day immediately after treatment. Regurgitation episodes decreased further to 4 ± 1 episodes at 6 months after training. CONCLUSIONS Rumination is produced by an unperceived somatic response to food ingestion that disrupts abdominal accommodation and can be effectively corrected by biofeedback-guided control of abdominothoracic muscular activity.

Abstract
Rumination syndrome is a behavioral disorder resulting in effortless regurgitation of undigested food within minutes of meal intake that is subsequently either re-swallowed or ejected. It is commonly misdiagnosed, patients often undergo extensive testing and multiple therapies, many of which are directed at suspected gastroparesis. A 25-year-old Caucasian female initially presented to our care 1 year ago with a 4-year history of nausea and vomiting occurring in the immediate postprandial period, specifically within 15 minutes from oral intake. She had an extensive history of multiple diagnostic, therapeutic and surgical procedures over the previous 4 years which included cholecystectomy, botulin toxin injection into the pyloric sphincter, pyloroplasty, placement of a gastric stimulator and jejunal feeding tube with no sustained results. On a previous admission we determined the functional status of the stomach by obtaining full thickness gastric biopsies during a diagnostic laparoscopy. This revealed an adequate population number of cells of Cajal and myenteric neurons as well as normal stomach muscle. After 1 year of attempting “breathing relaxation techniques”, while being nutritionally maintained by nocturnal jejunostomy feedings, the patient presented again to our care with refractory nausea and vomiting and unable to work or function. Her weight was 90 lbs. She underwent a subtotal gastrectomy (80%) with Roux-en-Y reconstruction and continuation of jejunostomy feeding. The refractory nausea and vomiting significantly improved over the 4 weeks after discharge and breathing exercises were continued. On subsequent follow-up visits over a 6-month course, the refractory nausea and vomiting had resolved by more than 85% with and improvement in her BMI and quality of life.The recommended treatment of rumination syndrome is focused on breathing exercises and relaxation techniques to “distract” while eating. We believe our case is the first reported where a subtotal gastrectomy has been used to help overcome refractory rumination along with the usual therapy. This surgery is a “last resort” consideration to improve quality of life, returning the patient to employment and functional social status.

Abstract
Rumination syndrome is the non-purposeful regurgitation of recently ingested food from the stomach to the mouth, where it is either expelled or reswallowed. Adolescent rumination syndrome (ARS) is a rare condition of which many physicians are unaware. Patients often are misdiagnosed or undergo costly testing, and as a result, diagnosis and treatment are often delayed. While ARS is not life-threatening, it does have medical and emotional effects on the patient and the patient's family. Diagnosis of ARS is based upon the Rome III diagnostic criteria. Antroduodenal manometry, while not required for a diagnosis, can be helpful to confirm the diagnosis. The pathogenesis of this disorder is complex and not well understood. However, because of its behavioral component, treatment of ARS requires a multidisciplinary approach that includes both medical management of symptoms and implementation of strategies that address behavioral, psychological, and general quality-of-life components of the disorder.

Abstract
Adolescent Rumination Syndrome (ARS) is a relatively uncommon disorder, defined by the involuntary regurgitation of recently ingested food from the stomach to the mouth, where it is either expelled or re-swallowed. Although the disorder itself is not life-threatening, it typically has a significant medical and psychosocial impact on the patient and family. There continues to be limited awareness about the clinical presentation, diagnosis, and treatment of ARS among clinicians. As such, adolescents presenting with symptoms of ARS often are misdiagnosed and typically undergo avoidable, extensive, invasive, and costly testing. This article seeks to increase awareness and knowledge about ARS, and to provide the clinician with practical guidelines regarding the pathogenesis, assessment, diagnosis, and treatment of ARS.

Abstract
PURPOSE To highlight new knowledge and technologies that support the transfer of skills generally acquired by speech language pathologists (SLPs) in academic training programs and clinical practice to involvement in the evaluation and management of individuals with disorders such as paradoxical vocal fold movement (PVFM), chronic cough, manifestations of extra-esophageal reflux (EER), esophageal dysphagia and rumination disorder. RECENT FINDINGS A range of studies published in the previous year provide data to support SLP involvement in the management of some disorders, including PVFM, chronic cough, and some manifestations of EER, both as providers and as clinical resources for other health professionals. However, little research is available that describes the role of SLPs in management of esophageal dysphagia or rumination disorder. SUMMARY Recent research supports the expanded role of the SLP in the interdisciplinary management of PVFM, chronic cough, manifestations of EER, esophageal dysphagia, and rumination. SLP and other health professionals involved in the care of these patients must find a balance between the practical challenges of treating individuals with increasingly complex medical issues and staying abreast of the latest developments in the diagnosis and treatment of these disorders.

Abstract
BACKGROUND Rumination syndrome (RS) is a functional gastrointestinal disorder (FGD) increasingly recognized in children and adolescents. The epidemiology of this condition in school aged children is poorly understood. The main objective of this study was to assess the prevalence of rumination and other related associations in a cohort of Sri Lankan children. METHODS Children aged 10-16 years were randomly selected from 8 schools in 4 provinces in Sri Lanka. RS was diagnosed using Rome III criteria. Data was collected using a self administered questionnaire distributed in an examination setting. It was translated into Sinhala, the native language and pretested before distribution. RESULTS A total of 2163 children were included in the study (55% boys, mean age 13.4 years, SD 1.8 years). Prevalence of RS was 5.1% (n = 110); boys 5.1% and girls 5.0%. When symptoms were analyzed, 73.6% reported re-swallowing of regurgitated food, while the rest spat it out. In 94.5% regurgitation occurred during the first hour after the meal. Only 8.2% had daily symptoms while 62.7% had symptoms weekly. Abdominal pain, bloating and weight loss were the commonest symptoms associated with RS (19.1%, 17.3% and 11.8% respectively). No significant association was observed between exposure to stressful events and rumination (p > 0.05). Twenty (18.2%) with RS fulfilled Rome III criteria for at least one other FGD. School absenteeism was seen in 11.8% of affected children. CONCLUSION RS was reasonably common in this cohort of school-aged children and adolescents in Sri Lanka. However, symptoms were severe enough to affect schooling only in 12% of affected children. Around one fifth with RS had at least one other overlapping FGD.

Abstract
Rumination syndrome is known to exist in infants and mentally retarded adults since long time. In past few years, some reports appeared that showed its existence in adult patients also. It is frequently confused with the intractable vomiting in adults and misdiagnosis leads to delay in appropriate management. We are here describing the case of a female patient with rumination syndrome where specific points in the history delineated the presence of this illness and helped in appropriate management. The patient became symptom free soon after the diagnosis was reached.

Abstract
BACKGROUND Rumination syndrome is a disorder of unknown etiology characterized by regurgitation of recently ingested food. We aimed to improve the diagnosis of rumination syndrome by classification of separate rumination symptoms using (1) an ambulatory manometry/impedance (AMIM) measurement and (2) a single-catheter high-resolution manometry/impedance (HRIM) measurement. METHODS A total of 96 symptoms during AMIM and 37 symptoms during HRIM were analyzed in five patients with clinically diagnosed rumination syndrome. KEY RESULTS AMIM identified rumination events in 85 out of 96 reported symptoms (symptom index (SI): 89%). Of these events, 63% were non-acidic and would have been missed by pH-metry. HRIM identified 32 out of 37 reported symptoms (SI: 86%). Upper esophageal sphincter (UES) relaxation was observed during all rumination events identified by HRIM and could be an additional criterion in the definition of rumination events. CONCLUSIONS Impedance measurement and high-resolution manometry contribute to a more detailed description of rumination events. Rumination events defined as gastric strain, common cavity phenomenon, retrograde esophageal fluid flow, and UES relaxation show a high SI when measured with AMIM or single-catheter HRIM.

Abstract
BACKGROUND Rumination syndrome is an uncommon condition characterised by the self-induced regurgitation from the stomach to the mouth of recently ingested meal that is chewed and reswallowed. Rumination is caused by a voluntary rise in intra-abdominal and intra-gastric pressure leading to the reflux of the gastric content into the oesophagus. However, the precise mechanisms preventing reflux at the gastro-oesophageal junction during the rise in intra-gastric pressure remains unknown. METHODS In 5 patients, rumination episodes were monitored using combined multiple intra-luminal impedance monitoring, high resolution manometry, and video-fluoroscopic recording. RESULTS We showed that the gastro-oesophageal junction moved from the abdominal cavity into the thorax creating a "pseudo-hernia". This occurred at a range of 1.4 ± 0.3 s before the rise in intra-oesophageal pressure and the gastro-oesophageal reflux. CONCLUSION This displacement of the gastro-oesophageal junction into thorax, rather than a lower oesophageal sphincter opening, explains the mechanism of voluntary regurgitations occurring during rumination syndrome.

Abstract
BACKGROUND Rumination syndrome is a condition that occurs when people constantly regurgitate and expel or reswallow food soon after they eat. The most severe cases of rumination syndrome can be debilitating, requiring total parenteral nutrition or enteral tube feedings. We report our experience with the treatment of children with severe rumination syndrome. PATIENTS AND METHODS Five patients with severe rumination syndrome received a novel inpatient interdisciplinary approach, which involved pediatric psychology, pediatric gastroenterology, clinical nutrition, child life, therapeutic recreation, and massage therapy. RESULTS Inpatient hospitalization lasted between 9 and 13 days. The treatment was successful in all 5 of the patients. They left with complete caloric intake orally. CONCLUSIONS This treatment protocol could benefit pediatric gastroenterologists, pediatricians, and child psychologists in managing both standard and severe cases of rumination syndrome.

Abstract
BACKGROUND Rumination syndrome, characterised by the effortless, often repetitive, regurgitation of recently ingested food into the mouth, was originally described in children and in the developmentally disabled. It is now well-recognised that rumination syndrome occurs in patients of all ages and cognitive abilities. AIM To review a scholarly review on our current understanding of the rumination syndrome. METHODS The review was conducted on the basis of a medline search to identify relevant publications pertaining to the pathophysiology, clinical diagnosis and management of rumination syndrome. RESULTS The Rome III consensus established diagnostic criteria for rumination syndrome in adults, children and infants. A typical history can be highly suggestive but oesophageal (high resolution) manometry/impedance with ingestion of a meal may help to distinguish rumination syndrome from other belching/regurgitation disorders. The pathophysiology is incompletely understood, but involves a rise in intra-gastric pressure, generated by a voluntary, but often unintentional, contraction of the abdominal wall musculature, at a time of low pressure in the lower oesophageal sphincter, causing retrograde movement of gastric contents into the oesophagus. To date, controlled trials in the treatment rumination syndrome are lacking. The mainstay of treatment for rumination syndrome is explanation and behavioural treatment which consists of habit reversal techniques that compete with the urge to regurgitate. Chewing gum, prokinetics, baclofen and even antireflux surgery have been proposed as adjunctive therapies, but high quality studies are generally lacking. CONCLUSIONS Rumination is an under-recognised condition with incompletely understood pathophysiology. Behavioural therapy seems effective, but controlled treatment trials are lacking.

Abstract
BACKGROUND Rumination is an eating disorder clinically suspected in the presence of chronic regurgitation of recently ingested food with subsequent re-mastication and swallowing. Oesophageal manometry is currently used to confirm the diagnosis, however, it is difficult to distinguish rumination from postprandial belching-regurgitation, being the manometric pattern identical in both situations. Oesophageal impedance allows recognition between liquid and gas gastro-oesophageal reflux. Our aims were (i) to improve diagnosis of rumination using combined impedance-manometry (ii) to assess the gastro-oesophageal pressure-flow pattern in rumination events. METHODS Sixteen patients with clinically suspected rumination underwent impedance-manometry monitoring for 1 h after a solid liquid meal. Manometry was first analysed blindly to the impedance pattern. All events marked by the patients and straining episodes were identified. After the manometric analysis, impedance tracings were unblinded and each straining episode was analysed for presence of liquid and/or gas oesophageal retrograde flow. Only rumination events were included for additional evaluation. KEY RESULTS Postprandial manometry showed a pattern compatible with rumination in 12/16 patients. In total, impedance-manometry confirmed the clinical diagnosis of rumination in eight of the 16 patients with clinical suspicion of rumination. In 102 clearly identified rumination events, the onset of gastric strain (manometry) occurred before the onset of oesophageal liquid retroflow (impedance) in 58% of cases or simultaneously in 37% of cases. In most cases (86%), oesophageal retrograde flow started after an initial increase in abdominal pressure but before the peak gastric strain pressure. CONCLUSIONS & INFERENCES 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.

Abstract
Tests of gastric neuromuscular function are used to evaluate patients with symptoms referable to the upper digestive tract. These symptoms can be associated with alterations in the rates of gastric emptying, impaired accommodation, heightened gastric sensation, or alterations in gastric myoelectrical function and contractility. Management of gastric neuromuscular disorders requires an understanding of pathophysiology and treatment options as well as the appropriate use and interpretation of diagnostic tests. These tests include measures of gastric emptying; contractility; electrical activity; regional gastric motility of the fundus, antrum, and pylorus; and tests of sensation and compliance. Tests are also being developed to improve our understanding of the afferent sensory pathways from the stomach to the central nervous system that mediate gastric sensation in health and gastric disorders. This article reviews tests of gastric function and provides a basic description of the tests, the methodologies behind them, descriptions of the physiology that they assess, and their clinical utility.

Abstract
Rumination in adults is considered to be the effortless regurgitation of recently ingested food into the mouth, followed by either rechewing and reswallowing or expulsion of the regurgitate. On the basis of the definition of rumination as a unique category of functional gastroduodenal disorders, according to the newly established Rome III classification, a review of the pathophysiology, diagnosis and treatment of the rumination syndrome in adults is presented after systematic and critical approach of all articles that could be retrieved through PubMed using the term "rumination".

Abstract
This article describes the case of a 19-year-old woman presenting with repetitive episodes of effortless vomiting, which started within 3 weeks of her naval boot camp training. She underwent a battery of costly investigations before the diagnosis of rumination syndrome could be made. One of the reasons for her delayed diagnosis is that many physicians are unaware of, or are reluctant to make the diagnosis of rumination syndrome. The purpose of this article is to make the general physician aware of the possibility of rumination syndrome in adolescents and adults of normal intelligence, even though it was initially considered only in infants and mentally retarded individuals. The key to diagnosis is a thorough patient history. Reassurance and behavioral therapy is the mainstay of treatment, with a reported success of >80%.

Abstract
BACKGROUND AND AIM This prospective study was conducted to characterize the clinical features of adult rumination syndrome, in the absence of psychiatric illness, by applying newly modified clinical criteria, and to elucidate factors influencing outcomes after treatment. METHODS Twenty-one adult patients diagnosed with rumination syndrome at a tertiary referral center over a 2-year period were enrolled in the study. All patients received supportive psychotherapy and medical treatment. Changes in symptom parameters were analyzed using a pretreatment and a post-treatment questionnaire. Patients were classified into three groups according to symptomatic outcome: improved group, sustained group and aggravated group. RESULTS The duration of treatment was longer in the improved group than in the sustained or aggravated groups (P = 0.018). Esophageal manometry testing demonstrated non-transmitted contractions of the esophageal body in 10 patients (47.6%) and low amplitude contractions in eight patients (38.1%). Mean lower esophageal sphincter (LES) pressure was 9.8 +/- 2.6 mmHg. Baseline LES pressure in the improved group was higher than in the other groups (P = 0.001). Ambulatory 24-h esophageal pH monitoring showed pathological acid reflux in six patients (28.6%). All pathological acid reflux occurred in post-rumination periods. Scintigraphic testing of gastric emptying revealed that the mean retention rate at 120 min was 34.2 +/- 2.5% of initial contents, and delayed emptying was noted in three patients (14.3%). CONCLUSIONS Rumination syndrome is often accompanied by heterogeneous conditions such as postprandial gastroesophageal reflux, various abnormalities in esophageal manometric tests and delayed gastric emptying. Medical treatment and supportive psychotherapy can be effective in otherwise normal adult patients, especially in patients who comply with long durations of treatment and who demonstrate higher baseline LES pressures.

Abstract
Aerophagia and rumination syndrome are functional upper gastrointestinal disorders that are becoming increasingly recognized in otherwise-healthy children and adults. Aerophagia is primarily characterized by troublesome repetitive belching and abdominal symptoms that result from air sucking and swallowing. Rumination syndrome is primarily characterized by regurgitation occurring shortly after meal intake. Physiologic studies suggest that both disorders are a result of habitual behavior with associated esophageal and gastric physiologic deviations. However, the underlying etiology of these disorders remains unclear. Studies examining optimal treatments are lacking. However, therapeutic approaches utilizing biofeedback may be helpful in alleviating symptoms for patients with these conditions.

Abstract
OBJECTIVES To characterize the clinical features, results of diagnostic testing, and treatment outcomes for children and adolescents with rumination syndrome. METHODS Review of the medical records for all 147 patients ages 5 to 20 diagnosed with rumination syndrome at our institution between 1975 and 2000. Data are presented as mean +/- the standard error of the mean. RESULTS Sixty-eight percent were female. Age at diagnosis was 15.0 +/- 0.3 years. Symptom duration before diagnosis was 2.2 +/- 0.3 years, 73% missed school/work, and 46% had been hospitalized because of symptoms. Before diagnosis, 16 (11%) underwent surgery for evaluation or management of symptoms. Twenty-four (16%) had psychiatric disorders; 3.4% had anorexia or bulimia nervosa. All patients described postprandial regurgitation after almost every meal (2.7 +/- 0.1 meals per day). Weight loss was described by 42.2% (median: 7 kg). Additional symptoms included: abdominal pain, 38%; constipation, 21%; nausea, 17%; and diarrhea, 8%. Structural studies were normal. Gastric emptying of solids at 4 hours was delayed in 26 of 56 patients. Esophageal pH testing in 24 patients showed reflux/regurgitation in 54%. Gastroduodenal manometry in 65 patients showed characteristic rumination-waves in 40%. Outcome data (at median follow-up 10 months) were available for 54 patients. Symptoms resolved in 16 (30%) and improved in 30 (56%). CONCLUSIONS Recognition of the clinical features of rumination syndrome in children and adolescents is essential; the diagnosis is often delayed and associated with morbidity. Extensive diagnostic testing is unnecessary. Early behavioral therapy is advocated, and patient outcomes are generally favorable.

Abstract
Anorexia nervosa is a complex psychiatric disorder with significant morbidity and mortality. It is important for gastroenterologists to be aware of the physiological effects and potential complications of anorexia nervosa, as they are frequently involved in treating patients with this disorder. We review the classic, GI, and neuroendocrinological features of anorexia nervosa. We also discuss gender differences and treatment options in anorexia nervosa. Further studies of GI physiology and pharmacology are needed to determine whether any disturbances may be amenable to therapeutic intervention. Future treatments directed at improving GI sensorimotor function and neurohormonal abnormalities in patients with anorexia nervosa may impact their nutritional rehabilitation and may have important health economic implications as patients avoid hospitalization and are restored to full activities in society. The current team approach, which incorporates psychiatrists, psychologists, nutritionists, pediatricians, internists, and gastroenterologists in the treatment of patients with anorexia nervosa, will continue to be essential.

Abstract
Rumination is an unusual gastrointestinal symptom that is characterized by the repetitive regurgitation of gastric contents into the oropharynx. The regurgitation occurs very soon after a meal and tends to persist for 1 to 2 hours. Rumination is defined by the setting in which it occurs. It is seen in three distinct populations: infants; individuals with psychiatric and neurologic disorders, particularly developmental disabilities; and adults who do not have overt psychiatric or neurologic disorders. The hallmark of rumination, which separates it from other disorders of the upper gastrointestinal tract (such as gastroesophageal reflux disease or cyclic vomiting syndrome), is the fact that in patients with rumination, the gastric contents appear in the oropharynx without retching or nausea. Rather, the patient makes a conscious decision on how to handle the regurgitated material after it presents into the oropharynx. The regurgitated meal usually consists of undigested or partially digested food. The regurgitation is effortless or at most is preceded by a sensation of belching immediately prior to the regurgitation itself. The management of patients with rumination needs to be accomplished in a highly individualized manner. Children with infant rumination syndrome often have symptoms related to significant defects in bonding with their mother. Thus, problems of mother-child bonding in pediatric patients with rumination syndrome should be identified and appropriately addressed. The management of adult patients with developmental disabilities or neurologic impairments who ruminate focuses mainly on behavioral modalities, including adversive conditioning and contingency management. The healthy adult who ruminates and has no evidence of neurologic or developmental disability is best seen as someone with a habit. Management in these patients is directed towards adjunctive therapies (ie, the use of proton pump inhibitors or H(2 )receptor antagonists to decrease acid injury to the esophagus) as well as identifying situations and emotions that trigger the patient's symptoms. Randomized controlled trials of various treatment modalities need to be undertaken; likewise, the evaluation strategy needed to best diagnose rumination is yet to be well defined. At this time, the challenge for gastroenterologists is to understand the nature of rumination, to identify individuals at high risk, and to use the management strategies most associated with good outcomes in patients with rumination in various clinical settings.

Abstract
Chronic vomiting disorders with diverse causes are seen in children of all ages and present diagnostic and therapeutic challenges to pediatric gastroenterologists. Most patients are diagnosed by history, physical examination, and a basic work-up aimed at excluding obstructive and inflammatory causes. Intractable cases warrant further evaluation for clarification of the diagnosis. This review focuses on the pathophysiology of vomiting and four of the syndromes manifesting as chronic vomiting. It also includes a detailed exploration of the new tools available for evaluation of these syndromes.

Abstract
OBJECTIVES To evaluate the clinical presentation and to assess the usefulness of antroduodenal manometry (ADM) and the results of multidisciplinary team management in 12 neurologically normal adolescents (9 girls) with rumination. STUDY DESIGN All patients had extensive investigations that ruled out other causes of their chronic symptoms. We performed ADM in all patients. A multidisciplinary approach was used for the nutritional and behavioral rehabilitation of these patients. RESULTS The median age at presentation was 14 years (range, 9-19 years), and the average duration of symptoms was 17 months. All patients complained of postprandial, effortless regurgitation, and the majority had weight loss and abdominal pain. Results of fasting ADM were normal in all. The postprandial ADM showed brief, simultaneous pressure increases at all recording sites, associated with regurgitation in 8 patients. No emesis was observed in the other 4 children during the study. Treatment included nutritional support in combination with antidepressants and anxiolytics (n = 6), cognitive therapy with biofeedback or relaxation techniques (n = 7), and pain management (n = 2). Resolution or improvement of symptoms was seen in 10 of the 12 patients, and successful transition to oral feedings was achieved in all during the follow-up period, which ranged from 5 to 36 months. CONCLUSIONS Rumination is a distinct functional gastrointestinal disorder of otherwise healthy children and adolescents, which can be diagnosed on the basis of clinical features. The ADM shows a characteristic pattern and rules out motility disorders that are often confused with rumination. A multidisciplinary team approach is associated with satisfactory recovery in most patients.

Abstract
There is international agreement that dyspepsia refers to pain or discomfort centered in the upper abdomen. However, the term 'discomfort' has been variably defined. While other symptoms may often be simultaneously present, gastro-oesophageal reflux disease can usually be clearly distinguished by the presence of predominant heartburn. Dyspepsia is a frequent reason for consultation in primary care and in gastrointestinal practice. With the widespread availability and utilization of endoscopy, it has become evident that a structural (or organic) explanation is found in only a minority of patients presenting with dyspepsia. Operationally, functional dyspepsia is defined as persistent or recurrent dyspepsia for 3 or more months in the absence of a clinically identifiable structural disease causing the symptoms. It has been proposed, based on symptoms, that functional dyspepsia be subdivided into symptom subgroups to promote patient homogeneity. The initially proposed 'clustering' of symptoms into ulcer-like and dysmotility-like functional dyspepsia has proved a dismal failure because of the considerable overlap observed, the lack of stability over time and the failure to identify robust pathophysiological abnormalities or responses to therapy. A subcategorization based upon the most bothersome symptom is theoretically more attractive but needs to be prospectively and rigorously tested.
