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
Gastroesophageal reflux disease (GERD), a prevalent condition with multifactorial pathogenesis, involves esophageal motor dysmotility as a key contributing factor to its development. When suspected GERD patients have an inadequate response to proton-pump inhibitor (PPI) therapy and normal upper endoscopy results, high-resolution manometry (HRM) is utilized to rule out alternative diagnosis such as achalasia spectrum disorders, rumination, or supragastric belching. At present, HRM continues to provide supportive evidence for diagnosing GERD and determining the appropriate treatment. This review focuses on the existing understanding of the connection between esophageal motor findings and the pathogenesis of GERD, along with the significance of esophageal HRM in managing GERD patients. The International GERD Consensus Working Group introduced a three-step method, assessing the esophagogastric junction (EGJ), esophageal body motility, and contraction reserve with multiple rapid swallow (MRS) maneuvers. Crucial HRM abnormalities in GERD include frequent transient lower esophageal sphincter relaxations, disrupted EGJ, and esophageal body hypomotility. Emerging HRM metrics like EGJ-contractile integral and innovative provocative maneuver like straight leg raise have the potential to enhance our understanding of factors contributing to GERD, thereby increasing the value of HRM performed in patients who experience symptoms suspected of GERD.

Abstract
BACKGROUND Diagnosing gastroesophageal reflux disease (GERD) can be challenging given varying symptom presentations, and complex multifactorial pathophysiology. The gold standard for GERD diagnosis is esophageal acid exposure time (AET) measured by pH-metry. A variety of additional diagnostic tools are available. The goal of this consensus was to assess the individual merits of GERD diagnostic tools based on current evidence, and provide consensus recommendations following discussion and voting by experts. METHODS This consensus was developed by 15 experts from nine countries, based on a systematic search of the literature, using GRADE (grading of recommendations, assessment, development and evaluation) methodology to assess the quality and strength of the evidence, and provide recommendations regarding the diagnostic utility of different GERD diagnosis tools, using AET as the reference standard. KEY RESULTS A proton pump inhibitor (PPI) trial is appropriate for patients with heartburn and no alarm symptoms, but nor for patients with regurgitation, chest pain, or extraesophageal presentations. Severe erosive esophagitis and abnormal reflux monitoring off PPI are clearly indicative of GERD. Esophagram, esophageal biopsies, laryngoscopy, and pharyngeal pH monitoring are not recommended to diagnose GERD. Patients with PPI-refractory symptoms and normal endoscopy require reflux monitoring by pH or pH-impedance to confirm or exclude GERD, and identify treatment failure mechanisms. GERD confounders need to be considered in some patients, pH-impedance can identify supragrastric belching, impedance-manometry can diagnose rumination. CONCLUSIONS Erosive esophagitis on endoscopy and abnormal pH or pH-impedance monitoring are the most appropriate methods to establish a diagnosis of GERD. Other tools may add useful complementary information.

Abstract
The Lyon Consensus provides conclusive criteria for and against the diagnosis of gastro-oesophageal reflux disease (GERD), and adjunctive metrics that consolidate or refute GERD diagnosis when primary criteria are borderline or inconclusive. An international core and working group was assembled to evaluate research since publication of the original Lyon Consensus, and to vote on statements collaboratively developed to update criteria. The Lyon Consensus 2.0 provides a modern definition of actionable GERD, where evidence from oesophageal testing supports revising, escalating or personalising GERD management for the symptomatic patient. Symptoms that have a high versus low likelihood of relationship to reflux episodes are described. Unproven versus proven GERD define diagnostic strategies and testing options. Patients with no prior GERD evidence (unproven GERD) are studied using prolonged wireless pH monitoring or catheter-based pH or pH-monitoring off antisecretory medication, while patients with conclusive GERD evidence (proven GERD) and persisting symptoms are evaluated using pH-impedance monitoring while on optimised antisecretory therapy. The major changes from the original Lyon Consensus criteria include establishment of Los Angeles grade B oesophagitis as conclusive GERD evidence, description of metrics and thresholds to be used with prolonged wireless pH monitoring, and inclusion of parameters useful in diagnosis of refractory GERD when testing is performed on antisecretory therapy in proven GERD. Criteria that have not performed well in the diagnosis of actionable GERD have been retired. Personalisation of investigation and management to each patient's unique presentation will optimise GERD diagnosis and management.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is very prevalent in the general population, with a broad spectrum of clinical manifestations, requiring accurate diagnosis and treatment. AIM The aim of this expert review is to establish good clinical practice recommendations for the diagnosis and personalized treatment of GERD. METHODS The good clinical practice recommendations were produced by a group of experts in GERD, members of the Asociación Mexicana de Gastroenterología (AMG), after carrying out an extensive review of the published literature and discussing each recommendation at a face-to-face meeting. This document does not aim to be a clinical practice guideline with the methodology such a document requires. RESULTS Fifteen experts on GERD formulated 27 good clinical practice recommendations for recognizing the symptoms and complications of GERD, the rational use of diagnostic tests and medical treatment, the identification and management of refractory GERD, the overlap with functional disorders, endoscopic and surgical treatment, and GERD in the pregnant woman, older adult, and the obese patient. CONCLUSIONS An accurate diagnosis of GERD is currently possible, enabling the prescription of a personalized treatment in patients with this condition. The goal of the good clinical practice recommendations by the group of experts from the AMG presented in this document is to aid both the general practitioner and specialist in the process of accurate diagnosis and treatment, in the patient with GERD.

Moshiree B, Drossman D, Shaukat A. AGA Clinical Practice Update on Evaluation and Management of Belching, Abdominal Bloating, and Distention: Expert Review. Gastroenterology 2023; 165:791-800.e3. [PMID: 37452811 DOI: 10.1053/j.gastro.2023.04.039] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 03/22/2023] [Accepted: 04/17/2023] [Indexed: 07/18/2023]
Abstract
DESCRIPTION Belching, bloating, and abdominal distention are all highly prevalent gastrointestinal symptoms and account for some of the most common reasons for patient visits to outpatient gastroenterology practices. These symptoms are often debilitating, affecting patients' quality of life, and contributing to work absenteeism. Belching and bloating differ in their pathophysiology, diagnosis, and management, and there is limited evidence available for their various treatments. Therefore, the purpose of this American Gastroenterological Association (AGA) Clinical Practice Update is to provide best practice advice based on both controlled trials and observational data for clinicians covering clinical features, diagnostics, and management considerations that include dietary, gut-directed behavioral, and drug therapies. METHODS This Expert Review was commissioned and approved by the AGA Institute Clinical Practice Updates Committee and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership, and underwent internal peer review by the Clinical Practice Updates Committee and external peer review through standard procedures of Gastroenterology. These best practice advice statements were drawn from a review of the published literature based on clinical trials, the more robust observational studies, and from expert opinion. Because systematic reviews were not performed, these best practice advice statements do not carry formal ratings regarding the quality of evidence or strength of the presented considerations. Best Practice Advice Statements BEST PRACTICE ADVICE 1: Clinical history and physical examination findings and impedance pH monitoring can help to differentiate between gastric and supragastric belching. BEST PRACTICE ADVICE 2: Treatment options for supragastric belching may include brain-gut behavioral therapies, either separately or in combination, such as cognitive behavioral therapy, diaphragmatic breathing, speech therapy, and central neuromodulators. BEST PRACTICE ADVICE 3: Rome IV criteria should be used to diagnose primary abdominal bloating and distention. BEST PRACTICE ADVICE 4: Carbohydrate enzyme deficiencies may be ruled out with dietary restriction and/or breath testing. In a small subset of at-risk patients, small bowel aspiration and glucose- or lactulose-based hydrogen breath testing may be used to evaluate for small intestinal bacterial overgrowth. BEST PRACTICE ADVICE 5: Serologic testing may rule out celiac disease in patients with bloating and, if serologies are positive, a small bowel biopsy should be done to confirm the diagnosis. A gastroenterology dietitian should be part of the multidisciplinary approach to care for patients with celiac disease and nonceliac gluten sensitivity. BEST PRACTICE ADVICE 6: Abdominal imaging and upper endoscopy should be ordered in patients with alarm features, recent worsening symptoms, or an abnormal physical examination only. BEST PRACTICE ADVICE 7: Gastric emptying studies should not be ordered routinely for bloating and distention, but may be considered if nausea and vomiting are present. Whole gut motility and radiopaque transit studies should not be ordered unless other additional and treatment-refractory lower gastrointestinal symptoms exist to warrant testing for neuromyopathic disorders. BEST PRACTICE ADVICE 8: In patients with abdominal bloating and distention thought to be related to constipation or difficult evacuation, anorectal physiology testing is suggested to rule out a pelvic floor disorder. BEST PRACTICE ADVICE 9: When dietary modifications are needed (eg, low-fermentable oligosaccharides, disaccharides, monosaccharides and polyols diet), a gastroenterology dietitian should preferably monitor treatment. BEST PRACTICE ADVICE 10: Probiotics should not be used to treat abdominal bloating and distention. BEST PRACTICE ADVICE 11: Biofeedback therapy may be effective for bloating and distention when a pelvic floor disorder is identified. BEST PRACTICE ADVICE 12: Central neuromodulators (eg, antidepressants) are used to treat bloating and abdominal distention by reducing visceral hypersensitivity, raising sensation threshold, and improving psychological comorbidities. BEST PRACTICE ADVICE 13: Medications used to treat constipation should be considered for treating bloating if constipation symptoms are present. BEST PRACTICE ADVICE 14: Psychological therapies, such as hypnotherapy, cognitive behavioral therapy, and other brain-gut behavior therapies may be used to treat patients with bloating and distention. BEST PRACTICE 15: Diaphragmatic breathing and central neuromodulators are used to treat abdominophrenic dyssynergia.

Abstract
BACKGROUND Supragastric belching (SGB) is a phenomenon where air is rapidly sucked from the pharynx into the esophagus and immediately expelled through abdominal straining. It is considered a behavior disorder and is increasingly recognized not only in patients with excessive belching, but also in those with reflux-like symptoms. Increased prevalence of esophageal hypomotility and increased acid exposure were previously reported in small cohorts of SGB patients. We aimed to clarify the impact of SGB on motility, reflux, and acid exposure in a large cohort of SGB patients. METHODS In a single-center database study, we searched for patients with pathological SGB. MII-pH and Manometry tracings were manually re-evaluated in all patients. Demographic, clinical, motility, reflux, and SGB-related data were gathered. KEY RESULTS Three hundred and forty-eight patients were included. Heartburn, belching, and regurgitation were the most common symptoms. Ineffective esophageal motility (IEM) was found in 27% of patients. SGB related to 47% of all reflux and to 53.6% of acid reflux events, and accounted for 27.3% of acid exposure time (AET). In those with severe SGB, 62% of acid reflux events and 46% of AET were SGB-related. CONCLUSIONS & INFERENCES Supragastric belching is common, associated with higher incidence of IEM and is responsible for almost a third of esophageal acid burden. The impact of SGB is proportional to its severity. Diagnosis of SGB should be sought in patients with excessive belching and in patients with refractory reflux symptoms. Recognizing SGB and treating patients with behavioral therapy may alleviate acid exposure and improve quality of life.

Abstract
Belching is defined as an audible escape of air from the esophagus or the stomach into the pharynx. It becomes pathologic if it is excessive and becomes bothersome. According to Rome IV diagnostic criteria, there is a belching disorder when one experiences bothersome belching (severe enough to impact on usual activities) more than 3 days a week. Esophageal impedance can differentiate between gastric and supragastric belching. The aim of this review was to provide data on pathogenesis and diagnosis of supragastric belching and study its relationship with gastroesophageal reflux disease and psychological factors. Treatment options for supragastric belching are also presented.

Abstract
BACKGROUND Behavioral therapy (BT) has been proven effective in the treatment of supragastric belching (SGB) in open studies. The aim was to compare BT to follow-up without intervention in patients with SGB in a randomized study. METHODS Forty-two patients were randomized to receive 5 sessions of BT, comprising diaphragmatic breathing exercises, or to follow-up without intervention. Patients were evaluated at 6 months, at which point the control group was also offered BT and evaluated after another 6 months. The frequency and intensity of belching and mental well-being were evaluated with a visual analog scale (VAS). Depression, anxiety, and health-related quality of life (HRQoL) were evaluated with four questionnaires: BDI, BAI, 15D, and RAND-36. KEY RESULTS The frequency and intensity of SGB were significantly lower in the therapy group (n = 19) than in the control group (n = 18) at the 6-month control (p < 0.001). When all patients (n = 36) were evaluated 6 months after BT, in addition to relief in the frequency and intensity of belching (p < 0.001), mental well-being had also improved (p < 0.05). Of all 36 patients, 27(75%) responded to BT. Depression scores were lower after therapy (p < 0.05). Only minor changes occurred in anxiety and HRQoL. CONCLUSIONS AND INFERENCES Behavioral therapy is superior to follow-up without intervention in patients with SGB in reducing belching and depression; it also improves mental well-being but has only a modest effect on anxiety and HRQoL.

Abstract
PURPOSE Belching is a common condition that frequently overlaps with other functional gastrointestinal disorders. While not associated with any increase in mortality, it is associated with impaired health-related quality of life. Management is challenging, as there are no pharmacologic therapies specifically targeted towards this disorder. This review covers pathogenesis, prevalence, and treatments for this condition, with specific emphasis on the evolving role of behavioral treatments in management. KEY FINDINGS The diagnosis of gastric and supragastric belching can usually be made clinically, without the need for invasive testing. If necessary, multichannel intraluminal impedance and pH testing can provide a more definitive diagnosis and can also be used to estimate the frequency of gastric and supragastric belching episodes, which each have a distinct appearance on impedance tracing. Belching disorders are commonly associated with gastroesophageal reflux disease and functional disorders of the gastrointestinal tract. Supragastric belching is also associated with behavioral disorders like anxiety and obsessive-compulsive disorder. Speech therapy, cognitive-behavioral therapy, and diaphragmatic breathing are all interventions that have recently shown promise in the management of this challenging disorder.

Abstract
Achalasia is the prototypical obstructive motor disorder diagnosed using HRM, but non-achalasia motor disorders are often identified in symptomatic patients. The clinical relevance of these disorders are assessed using ancillary HRM maneuvers (multiple rapid swallows, rapid drink challenge, solid swallows) that augment the standard supine HRM evaluation by challenging peristaltic function. Finding obstructive motor physiology in non-achalasia motor disorders may raise the option of invasive management akin to achalasia. Certain non-achalasia disorders, particularly hypermotility disorders, may manifest as epiphenomena seen with esophageal hypersensitivity. Symptomatic management is offered for superimposed reflux disease, psychological disorders, functional esophageal disorders, and behavioral disorders.

Clinical usefulness of esophageal high resolution manometry and adjunctive tests: An update. Dig Liver Dis 2021; 53:1373-1380.

Abstract
High resolution manometry (HRM), developed from conventional manometry, is the gold standard for assessment of esophageal motor function worldwide. The Chicago Classification, now in its fourth iteration, is the modern standard for HRM categorization of esophageal motility disorders. The HRM protocol has expanded from the original 10 supine swallow standard, to include upright swallows, and provocative maneuvers such as multiple rapid swallows, rapid drink challenge and standardized test meal. Impedance has been incorporated into HRM for visualization of bolus clearance. Futhermore, barium radiography and functional lumen imaging probe complement HRM when evidence of esophagogastric junction obstruction is inconclusive. The biggest impact of HRM is in the improved diagnosis and subtyping of achalasia spectrum disorders, with implications on management. Spastic disorders and absent contractility are better characterized. Within the reflux spectrum, HRM provides definition of morphology and tone of the esophagogastric junction, and assesses integrity of esophageal body peristalsis, which have pathophysiologic implications for reflux and its clearance. HRM provides characterization of behavioral disorders such as supragastric belching and rumination syndrome, which can mimic reflux disease. Thus, HRM has revolutionized the evaluation of esophageal motor function, and has expanded the utility of esophageal manometry in clinical practice.

Abstract
Background/Aims Belching is the act of expelling gas from the stomach or esophagus noisily through the oral cavity. Although it is a physiological phenomenon, belching may also be a symptom of upper gastrointestinal diseases such as reflux esophagitis and functional dyspepsia (FD). A detailed epidemiology of belching has not yet been reported. The aim of this study is to examine the prevalence and clinical characteristics of clinically significant belching (CSB) in adults. Methods We analyzed 1998 subjects who visited the hospital for annual health checkups. Belching was evaluated by a simple question “Do you burp a lot?” and scored as 0 (never), 1 (occasionally), 2 (sometimes), 3 (often), or 4 (always). Subjects with CSB were defined as having scores ≥ 3. We also collected the clinical parameters, endoscopic findings, and data according to the Athens Insomnia Scale, Rome IV questionnaire, and Hospital Anxiety and Depression Scale (HADS). Results Of the 1998 subjects, 121 (6.1%) had CSB. Subjects with CSB had FD more commonly than reflux esophagitis, but presence of heartburn was high (10.7% vs 3.1%). In addition, the HADS and Athens Insomnia Scale scores in subjects with CSB were significantly higher than those in subjects without CSB. Presence of heartburn (OR, 2.07; 95% CI, 1.05-4.09), presence of FD (OR, 2.12; 95% CI, 1.33-3.36), anxiety/depression (OR, 2.29; 95% CI 1.51-3.45), and sleep disturbances (OR, 1.73; 95% CI, 1.14-2.61) were significantly associated with CSB. Conclusion The detailed epidemiology of belching in the general adult population was clarified.

Abstract
BACKGROUND Supragastric belching (SGB) and rumination are behavioral disorders associated with proton pump inhibitor (PPI) non-response and can be diagnosed using multichannel intraluminal impedance-pH (MII-pH) and post-prandial high-resolution impedance manometry (PPHRIM). This pilot study compared diagnostic yield and inter-rater agreement for SGB and rumination using MII-pH and PPHRIM. METHODS Three esophageal physiologists performed blinded interpretations of MII-pH and PPHRIM in 22 PPI non-responders. Raters selected from 4 diagnostic impressions (normal, GERD, behavioral disorders, GERD+behavioral disorders) without clinical context. Primary outcomes were diagnostic impressions compared against clinical gold standard impression, between raters, and between test modalities. Following a 28-month wash-out period, raters re-interpreted MII-pH with clinical context and under consensus definition of diagnostic criteria. KEY RESULTS Compared to gold standard, rater accuracy for presence of behavioral disorders ranged from 45 to 77% on MII-pH and 45-59% on PPHRIM. On MII-pH, inter-rater agreement was fair for diagnosis (ĸ0.32, p < 0.01) and suboptimal for presence of behavioral disorders (ĸ0.13, p = 0.14). On PPHRIM, inter-rater agreement was suboptimal for both diagnosis (ĸ0.03, p = 0.34) and presence of a behavioral disorder (ĸ-0.22, p = 0.96). Inter-rater agreement improved in post hoc MII-pH interpretations. Rumination was more frequently identified on PPHRIM (23, 35%) compared to MII-pH (7, 11%). CONCLUSIONS AND INFERENCES Diagnostic accuracy and inter-rater agreement are higher for MII-pH than PPHRIM, and behavioral disorders are more frequently identified on PPHRIM. Identifying behavioral disorders on MII-pH and PPHRIM has implications for clinical evaluation of PPI non-response; clinical context is essential for accurate study interpretation. Further work is needed to standardize definitions and interpretations.

Abstract
BACKGROUND Aerophagia is a functional gastrointestinal disorder characterized by repeated air swallowing leading to chronic abdominal distension. Symptoms can be long lasting, lead to frustration, and distress. This study describes prevalence, related factors, and symptomatology of aerophagia, together with its relationship with emotional stress. MATERIALS AND METHODS Cross-sectional study. Adolescents aged 10 to 17 years from selected state schools by convenient sampling from Jakarta, Indonesia, were recruited. Rome III self-administered questionnaire was used to compile data on gastrointestinal symptoms. Data on sociodemographic characteristics, intestinal and extraintestinal symptoms, and stressful life events were collected using a separate questionnaire. RESULTS A total of 1796 questionnaires were included in the analysis [males 732 (40.8%), mean age 13.58 (SD 0.992) years]. There were 81 (4.5%) subjects diagnosed with aerophagia. When the criterion of belching was removed from the diagnosis of aerophagia, the prevalence drops to only 2 (0.1%). subjects. Bivariate analysis showed that sociodemographic factors have no correlation with aerophagia. In subjects with aerophagia, among the intestinal-related and extraintestinal symptoms, only loss of appetite was significantly more common in the aerophagia population (33.3%) when compared with controls (22.8%). Death of a close family member [adjusted odds ratio (OR), 2.78; 95% confidence interval (CI), 1.46-5.31; P=0.002], divorce or separation of parents (adjusted OR, 2.54; 95% CI, 1.38-4.66; P=0.003), and divorce followed by separate individual remarriage of parents (adjusted OR, 2.01; 95% CI, 1.01-3.98; P=0.046) were found to be significantly associated with aerophagia by multivariate analysis. CONCLUSIONS The prevalence of aerophagia was found in 4.5% of Indonesian school-aged children according to Rome III criteria, but the prevalence was found only 0.1% if the belching is removed from the criteria. Besides the main symptoms, only loss of appetite was significantly more common in aerophagia among intestinal-related and extraintestinal symptoms. Family-related stress showed a significant correlation with aerophagia.

Autophagy inhibition facilitates wound closure partially dependent on the YAP/IL-33 signaling in a mouse model of skin wound healing. FASEB J 2021; 35:e21920.

Abstract
Autophagy is a self-phagocytic and highly evolutionarily conserved intracellular lysosomal catabolic system, which plays a vital role in a variety of trauma models, including skin wound healing (SWH). However, the roles and potential mechanisms of autophagy in SWH are still controversial. We firstly investigated the role of autophagy in SWH-induced wound closure rate, inflammatory response, and histopathology, utilizing an inhibitor of autophagy 3-methyladenine (3-MA) and its agonist rapamycin (RAP). As expected, we found 3-MA treatment remarkably increased the wound closure rate, combated inflammation response, and mitigated histopathological changes, while RAP delivery aggravated SWH-induced pathological damage. To further exploit the underlying mechanism of autophagy regulating inflammation, the specific inhibitors of yes-associated protein (YAP), Verteporfin, and Anti-IL-33 were applied. Herein, treating with 3-MA markedly suppressed the expression of tumor necrosis factor-α (TNF-α), IL-1β, and IL-6, promoted that of IL-10, IL-33, and ST2, while RAP administration reverted SWH-induced the up-regulation of these inflammatory cytokines mentioned above. Importantly, Verteporfin administration not only down-regulated the expression levels of YAP, TNF-α, and IL-6 but also up-regulated that of IL-33 and IL-10. Unexpectedly, 3-MA or RAP retreatment did not have any impact on the changes in IL-33 among these inflammatory indicators. Furthermore, elevated expression of IL-33 promoted wound closure and alleviated the pathological damage, whereas, its antagonist Anti-IL-33 treatment overtly reversed the above-mentioned effects of IL-33. Moreover, 3-MA in combination with anti-IL-33 treatment reversed the role of 3-MA alone in mitigated pathological changes, but they failed to revert the effect of anti-IL-33 alone on worsening pathological damage. In sum, emerging data support the novel contribution of the YAP/IL-33 pathway in autophagy inhibition against SWH-induced pathological damage, and highlight that the autophagy/YAP/IL-33 signal axis is expected to become a new therapeutic target for SWH.

Characteristics of symptomatic belching in patients with belching disorder and patients who exhibit gastroesophageal reflux disease with belching. J Neurogastroenterol Motil 2021; 27:231-239. [PMID: 33424014 PMCID: PMC8026376 DOI: 10.5056/jnm20114] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Revised: 08/02/2020] [Accepted: 08/16/2020] [Indexed: 12/19/2022] Open
Abstract
Background/Aims Belching disorder (BD) is clinically distinct from gastroesophageal reflux disease (GERD) with belching. Supragastric belching (SGB) is closely associated with reflux episodes. This study investigates belch characteristics in association with reflux, compared between patients with BD and those who had GERD with belching. Methods Impedance pH monitoring data from 10 patients with BD and 10 patients with GERD who exhibited belching were retrospectively analyzed. Belches were considered "isolated" or "reflux-related" and acidic/non-acidic. Belch characteristics were compared between patients with BD and those with GERD. Results Symptomatic belches were more frequent in patients with BD than in patients with GERD (median, 160.5 vs 56.0, P < 0.05). SGB was the most common type in both groups; common subtypes comprised "isolated" in patients with BD and "isolated during the reflux period" in patients with GERD. Reflux-related SGB was more common in patients with GERD than in BD (78.3% vs 45.2%, P < 0.005). Both "preceding belching" including the reflux period and acidic SGB were more common in patients with GERD than in BD (31.8% vs 8.6% and 38.1% vs 8.9%, both P < 0.05). Supragastric belch number positively correlated with all reflux episodes in patients with GERD (adjusted R2 = 0.572, P = 0.007). Conclusions BD is characterized by more belching, compared to GERD. SGB is more frequently associated with reflux in GERD than in BD; acidity may be related to GERD. In BD, SGB is typically non-acidic and unrelated to reflux. Distinct SGB characteristics may reflect different pathogenic mechanisms of reflux and associated symptoms.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most commonly encountered digestive diseases in the world, with the prevalence continuing to increase. Many patients are successfully treated with lifestyle modifications and proton pump inhibitor therapy, but a subset of patients require more aggressive intervention for control of their symptoms. Surgical treatment with fundoplication is a viable option for patients with GERD, as it attempts to improve the integrity of the lower esophageal sphincter (LES). While surgery can be as effective as medical treatment, it can also be associated with side effects such as dysphagia, bloating, and abdominal pain. Therefore, a thorough pre-operative assessment is crucial to select appropriate surgical candidates. Newer technologies are becoming increasingly available to help clinicians identify patients with true LES dysfunction, such as pH-impedance studies and high-resolution manometry (HRM). Pre-operative evaluation should be aimed at confirming the diagnosis of GERD, ruling out any major motility disorders, and selecting appropriate surgical candidates. HRM and pH testing are key tests to consider for patients with GERD like symptoms, and the addition of provocative measures such as straight leg raises and multiple rapid swallows to HRM protocol can assess the presence of underlying hiatal hernias and to test a patient’s peristaltic reserve prior to surgery.

Abstract
Up to 40% of patients with symptoms suspicious of gastroesophageal reflux disease (GERD) do not respond completely to proton pump inhibitor (PPI) therapy. The term "refractory GERD" has been used loosely in the literature. A distinction should be made between refractory symptoms (ie, symptoms may or may not be GERD-related), refractory GERD symptoms (ie, persisting symptoms in patients with proven GERD, regardless of relationship to ongoing reflux), and refractory GERD (ie, objective evidence of GERD despite adequate medical management). The present ESNM/ANMS consensus paper proposes use the term "refractory GERD symptoms" only in patients with persisting symptoms and previously proven GERD by either endoscopy or esophageal pH monitoring. Even in this context, symptoms may or may not be reflux related. Objective evaluation, including endoscopy and esophageal physiologic testing, is requisite to provide insights into mechanisms of symptom generation and evidence of true refractory GERD. Some patients may have true ongoing refractory acid or weakly acidic reflux despite PPIs, while others have no evidence of ongoing reflux, and yet others have functional esophageal disorders (overlapping with proven GERD confirmed off therapy). In this context, attention should also be paid to supragastric belching and rumination syndrome, which may be important contributors to refractory symptoms.

Abstract
BACKGROUND & AIMS Reflux hypersensitivity (RH), a functional esophageal disorder, is detected in 14%-20% of patients who present with typical esophageal symptoms. As many as 40% of patients with RH do not respond to treatment with pain modulators or proton pump inhibitors (PPIs); behavior disorders might contribute to lack of treatment efficacy. We aimed to assess the prevalence of behavioral disorders and their effects on typical reflux symptoms in patients with RH. METHODS We performed a retrospective study of 542 patients with PPI-refractory esophageal symptoms (heartburn, regurgitation, or chest pain) or with symptoms that responded to PPI therapy, evaluated for anti-reflux surgery from January 2016 through August 2019 at a single center in London, United Kingdom. We collected data on symptoms, motility, and impedance-pH monitoring and assigned patients to categories of RH (n = 116), functional heartburn (n = 126), or non-erosive reflux disease (n = 300). RESULTS Of the 116 patients with a diagnosis of RH, 59 had only hypersensitivity, whereas 57 patients (49.2%) had either excessive supragastric belching (SGB, 39.7%), based on 24-hour impedance-pH monitoring, or rumination (9.5%), based on postprandial manometry combined with impedance. The prevalence of SGB and rumination in patients with RH was significantly higher than in patients with functional heartburn (22%; P < .001). Patients with RH and rumination were significantly younger (P = .005) and had the largest number of non-acid reflux episodes (P = .023). In patients with RH with SGB, SGB episodes were associated with 40.6% of marked reflux symptoms (heartburn, regurgitation, or chest pain), based on impedance-pH monitoring. In patients with RH and rumination, 40% of reflux-related symptoms (mostly regurgitation) were due to possible rumination episodes. CONCLUSIONS Almost half of patients with a diagnosis of RH have behavior disorders, including excessive SGB or rumination. Episodes of SGB or rumination are associated with typical reflux symptoms. Segregation of patients with diagnosis of RH into those with vs without behavioral disorders might have important therapeutic implications.

Abstract
BACKGROUND Gas-related abdominal symptoms are common in patients with functional gut disorders, but the responses to cope with the large volumes of gas that enter daily into the stomach have not been studied in detail. Our aim was to evaluate transit and tolerance of gastric gas in patients with functional gastrointestinal disorders. METHODS In eight healthy volunteers and 24 patients with functional gut disorders (eight functional dyspepsia, eight belching disorder, and eight functional bloating) 1500 ml of a gas mixture were infused into the stomach at 25 ml/min. Belching, rectal gas evacuation, and abdominal perception were continuously recorded for 90 minutes. KEY RESULTS Healthy subjects expelled the infused gas per rectum (1614 ± 73 ml), with a small rise in epigastric perception (score increment 1.0 ± 0.4) and virtually no belching (1 ± 1 belches). Patients with functional dyspepsia had a hypersensitive response to gastric gas, with a significant rise in epigastric perception (score increment 2.5 ± 0.6; P = .045), a transient delay in rectal gas evacuation and similar belching as healthy controls. Patients with belching disorders responded to gastric gas with continuous belches (33 ± 13 belches; P = .002), low epigastric perception, and a small reduction in rectal gas evacuation. Patients with functional bloating exhibited a slow transit response, with reduced rectal gas evacuation (1017 ± 145 ml; P = .002) and abdominal symptoms (score increment 2.5 ± 0.7), but without compensatory belching. CONCLUSIONS AND INFERENCES Different pathophysiological mechanisms underlay specific adaptive responses to gastric gas in patients with different functional gut disorders. Therapeutic interventions for gas-related abdominal symptoms should be addressed towards these specific pathophysiological disturbances.

Abstract
The most recent iteration of the classifications for functional esophageal disorders, Rome IV, proposed relevant modifications of the previous definitions for Rome III. They specifically considered increased esophageal acid exposure as the marker of gastroesophageal reflux disease (GERD), including the remaining part of non-erosive reflux disease patients with normal acid in the group with functional alterations, considering both reflux hypersensitivity and functional heartburn. However, recent pathophysiological and therapeutic data suggest the need for a return to including reflux hypersensitivity in the GERD spectrum. Indeed, physiologic alterations in esophageal mucosal integrity and chemical clearance, the presence of microscopic esophagitis, and strict symptom-reflux association support the concept that reflux hypersensitivity pertains to GERD. Surgical anti-reflux therapy has resulted in positive outcomes, even in the long term, in patients with reflux hypersensitivity and not in those with functional heartburn. Moreover, clinical trials using neuromodulators have been scarce and provided conflicting results. As a result, the real progress of the Rome IV classifications is in dispute. This article aims to summarize the most recent knowledge of non-erosive reflux disease and reflux hypersensitivity to discuss the utility of Rome IV criteria in the identification and management of functional esophageal disorders.

Abstract
OBJECTIVE To examine the psychometric properties of the nine-item Antepartum Gastrointestinal Symptom Assessment (AP-GI-SA) instrument. DESIGN Single-group prospective design. SETTING Urban prenatal clinic serving a diverse population. PARTICIPANTS Convenience sample of 45 pregnant women. METHODS Participants completed the AP-GI-SA before a scheduled prenatal care appointment. We used Bayesian structural equation modeling to evaluate the construct validity of the scale and assessed known-groups validity. We assessed reliability through maximal reliability coefficient estimate and measured internal consistency with Cronbach's alpha coefficient. RESULTS Participants completed the instrument in 2 minutes or less. Construct validity was supported by confirmatory factor analysis (posterior predictive p value = 0.49, gamma-hat = 0.970, and root mean square error of approximation = 0.065), which indicated that the single-factor model is a plausible data-generative model for GI symptoms. The maximal reliability coefficient of 0.75 and Cronbach's alpha coefficient of 0.67 supported reliability. Average AP-GI-SA scores were the highest for women in the third trimester. Of all nine GI symptoms, heartburn in the third trimester received the highest score. CONCLUSION Our findings provide preliminary support for the validity and reliability of the AP-GI-SA. The instrument may be used as a measure in intervention studies where GI symptoms of pregnancy are an outcome. The AP-GI-SA could also be useful in clinical settings to quickly evaluate GI symptoms.

Abstract
Belching is a physiological event that allows venting of swallowed gastric air. Excessive belching is a common presentation to gastroenterology clinics and could be isolated complains or associated with other gastrointestinal problems. PURPOSE OF THIS REVIEW: It is to describe the presentation, diagnosis, and treatment of belching disorders RECENT FINDINGS: These demonstrate that learned abnormal behaviors in response to unpleasant feeling in the abdomen are the driving causes for excessive belching and addressing these behaviors by speech pathology and cognitive behavior therapy considered as the keystone in its management SUMMARY: The gold standard in the diagnosis of belching is impedance monitoring by which belching is classified into supragastric belching and gastric belching.

Abstract
Background FD (functional dyspepsia) is a common functional gastrointestinal disorder, which lacks effective and safe treatment. Chinese herbal medicine (CHM) has been applied in FD treatment for thousands of years with satisfactory clinical outcomes. Zhishi is a classical traditional Chinese medicine used to treat FD. Weikang pian (WKP) is made of flavonoids extracted from zhishi which could effectively alleviate the symptoms of FD. This research aimed to assess the efficacy and safety of WKP in FD treatment. Methods This was a randomized, double-blinded and placebo-controlled clinical trial. The patients were diagnosed as FD according to RomeIII criteria. Then, FD patients were selected and assigned randomly to either WKP or placebo group. The subjects randomly received WKP or placebo for 4 weeks with 4 tablets each time, 3 times daily. The single dyspepsia symptom (SDS) scale and the gastric emptying function were measured before and after the treatment. Moreover, the safety of the trial and patient compliance were evaluated. Results A total of 60 FD patients were eventually enrolled in the trial, among them 45 patients in the WKP group and 15 patients in the placebo group. The primary outcome was the SDS scale, including assessments of postprandial distension, early satiety, epigastric burning, and pain. The secondary outcome was the gastric emptying function. Compared with the placebo group, the symptoms of FD in the WKP group were relieved after 4 weeks of treatment (P < 0.05). Some minor changes appeared in the four groups, but there were no significant differences in gastric emptying parameters of GER (2-hour gastric emptying rate) and GET/2 (gastric semiempty time) (P > 0.05). Severe adverse events were absent. The compliance to treatment was 94%–96%, and there was no significant difference between the groups. Conclusion WKP can relieve FD symptoms to some extent. This trial is registered with Chinese Clinical Trial Registry (ChiCTR): CTR 20132482.

Abstract
PURPOSE OF REVIEW Here, we discuss how esophageal motor testing plays important roles in patients with suspected gastroesophageal reflux disease (GERD). In addition to guiding appropriate placement of catheters for ambulatory reflux monitoring, esophageal high-resolution manometry (HRM) rules out confounding diagnoses, such as achalasia spectrum disorders, that can present with symptoms similar to that of GERD, but are managed very differently. RECENT FINDINGS HRM performed with impedance in the post-prandial setting (PP-HRIM) can assess for rumination syndrome or supragastric belching, which should be directed towards behavioral interventions. The recent GERD Classification of Motor Function recommends a hierarchical approach, focusing on (1) the esophagogastric junction (EGJ), (2) the esophageal body, and (3) esophageal contraction reserve, which can be assessed with provocative maneuvers at HRM, such as multiple rapid swallows (MRS). This approach can inform the appropriate tailoring of antireflux surgery. Novel esophageal motility metrics, such as the EGJ-contractile integral from HRM, or post-reflux swallow-induced peristaltic wave indices from 24-h pH-impedance monitoring, may also assist with GERD diagnosis. Assessment of esophageal motor function can contribute in a significant manner to the care of patients with suspected GERD, particularly when esophageal symptoms do not improve with antisecretory therapy, and/or when surgical or endoscopic antireflux therapies are under consideration.

Abstract
BACKGROUND To cope with the daily increments of gastric gas, the stomach can propel gas to the small bowel or trigger the belching reflex. Our aim was to evaluate transit of free gastric gas in healthy humans, and its relationship with abdominal symptoms. METHODS In 24 healthy volunteers a gas mixture was infused into the stomach at 0 mL/min (sham infusion), 25 mL/min, 50 mL/min, and 100 mL/min (n = 6 each) up to 1500 mL. Belching, rectal gas evacuation, and abdominal perception were continuously recorded for 90 min. KEY RESULTS Sham infusion was associated to low rectal gas evacuation (187 ± 94 mL after 90 min), and belching (0 ± 0). In contrast, gastric gas infusion increased rectal gas evacuation (1198 ± 176 mL; P = .025) and belching (4 ± 1 belches; P = .0520) without differences between the infusion rates tested. Overall, there was a negative correlation between rectal gas evacuation and belching (r = -.72; P < .0001): 6 subjects had frequent belching (14 ± 2 belches) and minor rectal gas evacuation (330 ± 112 mL), whereas 12 subjects had virtually no belches (1 ± 1 belches) and greater rectal gas evacuation (1630 ± 147 mL; P < .001 vs belchers for both). Gas infusion induced lower abdominal symptoms in belchers (score increment 0.7 ± 0.3) than in rectal gas evacuators (score increment 1.7 ± 0.5; P = .033). CONCLUSIONS AND INFERENCES An excellent balance between belching and distal gastric empting allows the stomach to adapt to great variations in gas intake. In general, most gastric gas is emptied to distal intestinal segments, but in some circumstances gastric gas induces belching, a mechanism that may improve gas tolerance.

ARQUIVOS DE GASTROENTEROLOGIA 2018; 55Suppl 1:76-84.

Abstract
BACKGROUND Prolonged monitoring increased our knowledge on gastroesophageal reflux (GER), and the disease became known as gastroesophageal reflux disease (GERD). Prolonged reflux monitoring permits the diagnosis of GERD when endoscopic findings are not enough to characterize it. OBJECTIVE The objective of this paper is to review the current knowledge on impedance-pH monitoring, taking into account the published literature and the authors experience with 1,200 exams. METHODS The different types of prolonged reflux monitoring, namely: conventional pHmetry, catheter-free pHmetry and impedance-pHmetry will be briefly described. The new possibilities of evaluation with impedance-pHmetry are emphasized, namely: the study of symptomatic patients in use of proton pump inhibitors (PPIs); evaluation of patients with symptoms suggestive of GERD although with normal endoscopy and normal pHmetry, diagnostic elucidation of patients with atypical symptoms or supra-esophageal symptoms, mainly chronic cough, study of patients complaining of belch, differentiating gastric and supra-gastric belching, and the proper work-up before anti-reflux surgery. RESULTS When impedance was associated to pH monitoring, an impressive technological evolution became apparent, when compared to pH monitoring alone. The main advantages of impedance-pHmetry are: the ability to detect all types of reflux: acid, non-acid, liquid, gaseous. In addition, other important measurements can be made: the ability of the esophagus in transporting the bolus, the measurement of basal mucosal impedance and the evaluation of primary peristalsis post reflux. CONCLUSION Impedance-pHmetry is a promising method, with great advantages over conventional pHmetry. The choice between these two types of monitoring should be very judicious. The authors suggest the importance of careful evaluation of each reflux episode by the physician responsible for the examination, necessary for the correct interpretation of the tracings.

Abstract
PURPOSE OF REVIEW Ambulatory reflux monitoring is typically performed when esophageal symptoms do not respond to usual antireflux medications, or prior to invasive antireflux therapy. Although pH-based metrics have been the standard in defining esophageal reflux burden, novel impedance parameters have been introduced in recent years that can either be extracted from pH-impedance monitoring or obtained directly from esophageal mucosa. This review evaluates the clinical role of esophageal pH-impedance monitoring in clinical practice in the present day. RECENT FINDINGS Elevated acid exposure time in the distal esophagus remains the primary metric that predicts symptom improvement from antireflux therapy. Although conventional impedance-based metrics (numbers of reflux episodes, reflux-symptom association) provide complementary evidence, novel impedance-based metrics show promise in documenting reflux-induced damage to esophageal mucosal integrity, and in potentially predicting treatment outcome. The postreflux swallow-induced peristaltic wave measures integrity of primary peristalsis triggered by a reflux episode. Baseline impedance values reflect histopathological damage to mucosal integrity, and improve following successful antireflux therapy. Mucosal impedance assessed at endoscopy is a new diagnostic tool that is currently being evaluated in multinational research studies. SUMMARY Esophageal pH-impedance monitoring has potential to augment confidence in a reflux diagnosis beyond that provided by pH-monitoring alone.

Diaphragmatic Breathing Reduces Belching and Proton Pump Inhibitor Refractory Gastroesophageal Reflux Symptoms. Clin Gastroenterol Hepatol 2018; 16:407-416.e2.

Abstract
BACKGROUND & AIMS In patients with gastroesophageal reflux disease (GERD) and excessive belching, most belches are supragastric, and can induce reflux episodes and worsen GERD. Supragastric belching (SGB) might be reduced with diaphragmatic breathing exercises. We investigated whether diaphragmatic breathing therapy is effective in reducing belching and proton pump inhibitor (PPI)-refractory gastroesophageal reflux symptoms. METHODS We performed a prospective study of 36 consecutive patients with GERD refractory to PPI therapy and a belching visual analogue scale (VAS) score of 6 or more, seen at a gastroenterology clinic at a tertiary hospital in Singapore from April 2015 through October 2016. Patients underwent high-resolution manometry and 24-hour pH-impedance studies while they were off PPIs. Fifteen patients were placed on a standardized diaphragmatic breathing exercise protocol (treatment group) and completed questionnaires at baseline, after diaphragmatic breathing therapy, and 4 months after the therapy ended. Twenty-one patients were placed on a waitlist (control subjects), completed the same questionnaires with an additional questionnaire after their waitlist period, and eventually received diaphragmatic breathing therapy. The primary outcome was reduction in belching VAS by 50% or more after treatment. Secondary outcomes included GERD symptoms (evaluated using the reflux disease questionnaire) and quality of life (QoL) scores, determined from the Reflux-Qual Short Form and EuroQoL-VAS. RESULTS Nine of the 15 patients in the treatment group (60%) and none of the 21 control subjects achieved the primary outcome (P < .001). In the treatment group, the mean belching VAS score decreased from 7.1 ± 1.5 at baseline to 3.5 ± 2.0 after diaphragmatic breathing therapy; in the control group, the mean VAS score was 7.6 ± 1.1 at baseline and 7.4 ± 1.3 after the waitlist period. Eighty percent of patients in the treatment group significantly reduced belching frequency compared with 19% in control subjects (P = .001). Treatment significantly reduced symptoms of GERD (the mean reflux disease questionnaire score decreased by 12.2 in the treatment group and 3.1 in the control group; P = .01). The treatment significantly increased QoL scores (the mean Reflux-Qual Short Form score increased by 15.4 in the treatment group and 5.2 in the control group; P = .04) and mean EuroQoL-VAS scores (15.7 increase in treatment group and 2.4 decrease in the control group). These changes were sustained at 4 months after treatment. In the end, 20 of the 36 patients who received diaphragmatic breathing therapy (55.6%), all with excessive SGB, achieved the primary outcome. CONCLUSIONS In a prospective study, we found a standardized protocol for diaphragmatic breathing to reduce belching and PPI-refractory gastroesophageal reflux symptoms, and increase QoL in patients with PPI-refractory GERD with belching-especially those with excessive SGB.

Clin Gastroenterol Hepatol 2018; 16:211-218.e1.

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
A detailed critique of objective measurements of gastroesophageal reflux disease (GERD) would improve management of patients suspecting of having reflux, leading to rational selection of treatment and better outcomes. Many diagnostic tests for GERD have been developed over the past decades. We analyze their development, positive- and negative-predictive values, and ability to predict response to treatment. These features are important for development of medical, surgical, and endoscopic therapies for GERD. We discuss the value of available diagnostic tests and review their role in management of patients with persistent reflux symptoms despite adequate medical or surgical treatment. This is becoming a significant health economic problem, due to the widespread use of proton pump inhibitors. GERD is believed to cause nonesophageal symptoms, such as those provoked by ear, nose, throat, or respiratory disorders. We analyze the value of GERD diagnostic tests in evaluation of these troublesome, nonesophageal symptoms.

Abstract
Excessive supragastric belching is rarely described in the anesthesia literature. Anesthesia planning of a 26-year-old patient with excessive supragastric belching, history of superior mesenteric artery syndrome (SMAS), and dental anxiety requires preoperative assessment. This case report outlines the anesthetic considerations and the management to facilitate comprehensive dentistry. Key anesthetic considerations include anxiolysis, aspiration risk reduction, total intravenous anesthesia (TIVA), and postoperative nausea and vomiting (PONV) prophylaxis.

Abstract
BACKGROUND An international group of experts evaluated and revised recommendations for ambulatory reflux monitoring for the diagnosis of gastro-esophageal reflux disease (GERD). METHODS Literature search was focused on indications and technical recommendations for GERD testing and phenotypes definitions. Statements were proposed and discussed during several structured meetings. KEY RESULTS Reflux testing should be performed after cessation of acid suppressive medication in patients with a low likelihood of GERD. In this setting, testing can be either catheter-based or wireless pH-monitoring or pH-impedance monitoring. In patients with a high probability of GERD (esophagitis grade C and D, histology proven Barrett's mucosa >1 cm, peptic stricture, previous positive pH monitoring) and persistent symptoms, pH-impedance monitoring should be performed on treatment. Recommendations are provided for data acquisition and analysis. Esophageal acid exposure is considered as pathological if acid exposure time (AET) is greater than 6% on pH testing. Number of reflux episodes and baseline impedance are exploratory metrics that may complement AET. Positive symptom reflux association is defined as symptom index (SI) >50% or symptom association probability (SAP) >95%. A positive symptom-reflux association in the absence of pathological AET defines hypersensitivity to reflux. CONCLUSIONS AND INFERENCES The consensus group determined that grade C or D esophagitis, peptic stricture, histology proven Barrett's mucosa >1 cm, and esophageal acid exposure greater >6% are sufficient to define pathological GERD. Further testing should be considered when none of these criteria are fulfilled.

Abstract
BACKGROUND Swallowed gas is an important source of abdominal gas, and aerophagia is often believed as a putative cause of gas-related abdominal symptoms. However, altered gas-swallow during meals has not been demonstrated. Our aim was to characterize the number of gas swallows during meals in patients complaining of excessive belching and gaseousness and a control group without abdominal symptoms during a 24-h period. METHODS A 24-h pH-impedance monitoring was performed in 10 patients with excessive belching, and 11 patients without digestive symptoms or reflux in the pH-impedance study. During the study, patients followed their daily routine and customary meals, without any specific limitation. In each patient the number and content of swallows and belches were analyzed. KEY RESULTS Total meal periods were similar in controls (75±26 min) and patients (79±21 min; P=.339), but the number of gaseous swallows was greater in patients (114±13 swallows) than controls (71±8 swallows; P=.007), due to a greater frequency of gaseous swallows during meals (15±2 swallows/10 min vs 10±1 swallows/10 min, respectively; P=.008). During the 24-h study period, 66±13 belches were recorded in patients, but only 13±3 belches in controls (P<.001), mainly gastric belches (80±4% and 92±2% of belches, patients, and controls, respectively) which showed a good correlation with the number of gaseous swallows performed during meals (r=.756; P=.011). CONCLUSION AND INFERENCES Gas is frequently swallowed during meals. Patients complaining of excessive belching have a different swallow pattern during meals, with an increased ingestion of gas that correlates with increased gastric belching events.

Abstract
A response in which a belch occurs without gastric involvement, i.e., the supragastric belch (SGB), has been characterized in humans. The aims of this study were to determine whether animals have an SGB and, if so, to determine its mechanisms. Studies were conducted in decerebrate cats (n = 30) with electromyographic electrodes on hyoid, pharyngeal, esophageal, and diaphragm muscles. The effects of distending different regions of the esophagus in different manners using a balloon were quantified to determine the most appropriate stimulus for activating the cat SGB. The effects of esophageal perfusion of lidocaine (n = 3), vagus nerve transection (n = 3), or esophageal acidification (n = 5) on activation of the SGB were determined. Rapid large distensions of the thoracic esophagus best activated responses similar to the human SGB, i.e., rapid inhalation followed by a belch. The rapid inhalation was associated with activation of hiatal fibers and the belch with activation of dome fibers of the diaphragm. The rapid inhalation response was independent of the belch response. Lidocaine perfusion of the esophagus blocked the belch response without blocking the rapid inhalation, HCl perfusion sensitized the esophagus to activation of both the rapid inhalation and the belch response, and vagotomy blocked both responses. We conclude that the cat has an SGB that is composed of two independent reflex responses, i.e., rapid inhalation and belch, that are mediated by the vagus nerves and tension/mucosal receptors of the esophagus and sensitized by esophageal acid exposure. We hypothesize that the SGB is a learned voluntarily activated reflex response.NEW & NOTEWORTHY Rapid strong distension of the thoracic esophagus activates rapid inhalation followed by a belch, which is the sequence of responses that compose the human supragastric belch (SGB). The rapid inhalation and belch phases of the cat SGB are activated by hiatal and dome fibers of the diaphragm, respectively, and are mediated by the vagus nerves and tension/mucosal receptors of the esophagus and sensitized by esophageal acid exposure. There are many similarities between the cat and human SGB.

[PMID: 28571727 DOI: 10.1016/j.jep.2017.05.026] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/29/2016] [Revised: 04/16/2017] [Accepted: 05/20/2017] [Indexed: 06/07/2023]
Abstract
ETHNOPHARMACOLOGICAL EVIDENCE Mentha pulegium L. leaves are used in the Iranian traditional medicine for the treatment of functional dyspepsia. AIM OF STUDY To study the efficacy and safety of M. pulegium in the treatment of functional dyspepsia patients fulfilling the Rome III criteria. MATERIALS AND METHODS The efficacy and safety of a standardized Mentha pulegium leaf extract (drug extract ratio: 15.9:1, extraction solvent: 70% v/v aqueous ethanol) (330mg three times daily taken for 2 months) as add-on to one famotidine 40mg tablet per day in the treatment of 50 functional dyspepsia patients were compared with those of a parallel placebo group (n =50). RESULTS The extract significantly decreased the total dyspepsia score measured by the Hong Kong dyspepsia index compared to the placebo and baseline (P=0.011 and P<0.001 respectively). The stomach pain, upper abdominal bloating, upper abdominal dull ache, belching and total dyspepsia scores were decreased from baseline in the extract group significantly compared to the placebo (P<0.001, P<0.001, P=0.003, P<0.001 and P<0.001 respectively). However, the decreases of other dyspepsia symptoms scores from baseline in the extract group were not significant compared to the placebo (P>0.05). The extract improved the quality of life measured by the SF-36 questionnaire significantly compared to the placebo and baseline (P=0.003 and P<0.001 respectively). Moreover, the extract lowered the rate of H. pylori infection determined by the urease test significantly compared to the placebo and baseline (P=0.001 and P<0.001 respectively). The extract did not significantly affect the complete blood count and liver and kidney function tests (P>0.05). The patients did not experience any adverse drug effect. CONCLUSIONS M. pulegium extract (genuine drug extract ratio: 19.4:1; extraction solvent: 70% v/v aqueous ethanol) 270mg three times daily taken for 2 months as adjunct to one famotidine 40mg tablet per day seems safe, improves dyspeptic symptoms and quality of life and eradicates H. pylori in functional dyspepsia patients.

Abstract
PURPOSE OF REVIEW Esophageal high-resolution manometry (HRM) is the current state-of-the-art diagnostic tool to evaluate esophageal motility patterns and, as such, is widely adopted in clinical practice. This article will review the interpretation of esophageal HRM in clinical practice. RECENT FINDINGS HRM uses a high-resolution catheter to transmit intraluminal pressure data that are subsequently converted into dynamic esophageal pressure topography (EPT) plots. Metric data from EPT plots are synthesized to yield an esophageal motility diagnosis according to the Chicago Classification, a formal analytic scheme for esophageal motility disorders, which is currently in version 3.0. The standard HRM protocol consists of a baseline phase and a series of 10 wet swallows in the supine or reclined position. In addition, data from swallows in the seated position and provocative HRM maneuvers provide useful information about motility properties. Combined high-resolution impedance technology is also clinically available and enables concurrent assessment of bolus transit and postprandial responses. Finally, there is ongoing interest to optimize the training and competency assessment for interpretation of HRM in clinical practice. SUMMARY Esophageal HRM is a valuable and sophisticated clinical tool to evaluate esophageal motility patterns. Emerging clinical applications of esophageal HRM include combined impedance technology, provocative maneuvers, and postprandial evaluation.

Abstract
Improving the quality of healthcare delivery is a cornerstone of modern medical care shared between all stakeholders. However, effectively improving quality requires both an understanding of the tenets of healthcare quality and how they relate to an individual disease process. This is especially important for common diseases, such as gastroesophageal reflux disease (GERD), where wide variations in practice exist. The high prevalence of GERD coupled with wide variation in clinical approach results in significant economic burden and poor quality of care. Thus, GERD serves as a useful framework to highlight the opportunities and current challenges of delivering high-quality care. In this article, we identify quality metrics in GERD and the areas in need of research to improve the quality of the management of GERD. Additionally, we suggest strategies for improvement as it relates to the proper diagnostic testing utilization and the decision-making process.

Impact of laparoscopic antireflux surgery on belching in pediatric GERD patients. Neurogastroenterol Motil 2016; 28:1525-32.

Abstract
BACKGROUND Laparoscopic antireflux surgery (LARS) is a well-established treatment option for children with proton pomp inhibitor (PPI)-resistant gastroesophageal reflux disease (GERD). Besides preventing reflux of gastric fluid and solid content, LARS may also impair the ability of the stomach to vent intragastric air (i.e. gastric belching) and induce gas-related complications, such as bloating and/or hyperflatulence. Furthermore, it was previously hypothesized that LARS induces a behavioral type of belching, not originating from the stomach, called supragastric belching. The aim of this study was to objectively evaluate the impact of LARS on gastric (GB) and supragastric belching (SGB) in children with GERD. METHODS We performed a prospective, Dutch multicenter cohort study including 25 patients (12 males, median age 6 (range 2-18) years) with PPI-resistant GERD who were scheduled for LARS. Twenty-four-hour multichannel intraluminal impedance pH monitoring (MII-pH monitoring) was performed before and 3 months after fundoplication. Impedance pH tracings were analyzed for reflux episodes and GBs and SGBs. KEY RESULTS LARS reduced acid exposure time from 8.5% (6.0-16.2%) to 0.8% (0.2-2.8%), p < 0.001. The number of GBs also significantly decreased after LARS (59 [43-77] VS 5 [2-12], p < 0.001). The number of air swallows remained unchanged after LARS. SGBs were infrequent before LARS with no change in the number of SGB observed after the procedure. Postoperative belching symptoms were associated with GBs, not with SGBs. CONCLUSION & INFERENCES LARS significantly reduces the number of GBs in children with GERD, whereas the number of air swallows remains unchanged. Postoperative symptomatic belching is associated with GBs, but not with SGBs. These findings suggest that LARS does not induce the occurrence of SGBs in children, but longer follow-up is required.

Abstract
The 21st century offers new advances in diagnostic procedures and protocols in the management of esophageal diseases. This review highlights the most recent advances in esophageal diagnostic technologies, including clinical applications of novel endoscopic devices, such as ultrathin endoscopy and confocal laser endomicroscopy for diagnosis and management of Barrett's esophagus; novel parameters and protocols in high-resolution esophageal manometry for the identification and better classification of motility abnormalities; innovative connections between esophageal motility disorder diagnosis and detection of gastroesophageal reflux disease (GERD); impedance-pH testing for detecting the various GERD phenotypes; performance of distensibility testing for better pathophysiological knowledge of the esophagus and other gastrointestinal abnormalities; and a modern view of positron emission tomography scanning in metastatic disease detection in the era of accountability as a model for examining other new technologies. We now have better tools than ever for the detection of esophageal diseases and disorders, and emerging data are helping to define how well these tools change management and provide value to clinicians. This review features novel insights from multidisciplinary perspectives, including both surgical and medical perspectives, into these new tools, and it offers guidance on the use of novel technologies in clinical practice and future directions for research.

Abstract
PURPOSE OF REVIEW Supragastric belching has recently gained recognition as a belching disorder of behavioral origin that can be accurately diagnosed on esophageal impedance monitoring. Its contribution to numerous other gastrointestinal disorders is beginning to be appreciated. Improved knowledge of its pathophysiology has enabled identification of therapeutic goals, some of which have been subject to formal study and demonstrated good outcomes. This review sets out to present and discuss new findings related to the improved understanding of the relationship between supragastric belching and other gastrointestinal disorders, as well as fresh concepts in terms of management. RECENT FINDINGS Supragastric belching is now shown to be associated with globus, as well as reflux symptoms in proton pump inhibitor nonresponders. Patients with supragastric belching experience higher frequency of belching events if they have concurrent esophageal hypomotility. Gum chewing and sleeve gastrectomy have no impact on supragastric belching. Pediatric studies suggest an overlap with aerophagia that is not observed in adults. Successful treatments trialed recently include psychoeducation and behavioral therapy delivered by a health psychologist with expertise in gastroenterology. SUMMARY With the foreseeable increase in recognition and diagnosis of pathological supragastric belching, there is a clear need to better understand its pathophysiology, especially in terms of its emerging importance in relation to other gastrointestinal disorders. Further study is justified to uncover additional therapeutic options for this benign but disabling condition.
