A 15-year-old man presented with an acute history of facial swelling following a bout of forceful eructation after eating. Subcutaneous emphysema was noted on examination of his left face and neck. He was initially managed with intravenous antibiotics for suspected facial infection. A chest radiograph performed on day 3 of admission identified subcutaneous emphysema of the upper thorax and neck. CT with oral contrast confirmed extensive subcutaneous emphysema of neck, thorax and upper abdomen, with associated pneumomediastinum. The site of air leak was not identified. He subsequently underwent upper gastrointestinal endoscopy and this was normal. Despite the delay in diagnosis, he remained haemodynamically stable, and repeated radiography showed improvement reflecting the benign course of this condition as described in existing literature. There are no previous published reports of spontaneous pneumomediastinum following eructation; therefore, high clinical suspicion should be maintained in this presentation.

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.

The hand-held laser methane detector (LMD) technique has been suggested as an alternative method for measuring methane (CH4) emissions from enteric fermentation of ruminants in the field. This study aimed to establish a standard procedure for using LMD to assess CH4 production in cattle and evaluate the efficacy of the protocol to detect differences in CH4 emissions from cattle fed with diets of different forage-to-concentrate (FC) ratios. Experiment 1 was conducted with four Hanwoo steers (584 ± 57.4 kg body weight [BW]) individually housed in metabolic cages. The LMD was installed on a tripod aimed at the animal's nostril, and the CH4 concentration in the exhaled gas was measured for 6 min every hour for 2 consecutive days. For the data processing, the CH4 concentration peaks were identified by the automatic multi-scale peak detection algorithm. The peaks were then separated into those from respiration and eructation by fitting combinations of two of the four distribution functions (normal, log-normal, gamma, and Weibull) using the mixdist R package. In addition, the most appropriate time and number of consecutive measurements to represent the daily average CH4 concentration were determined. In experiment 2, 30 Hanwoo growing steers (343 ± 24.6 kg BW), blocked by BW, were randomly divided into three groups. Three different diets were provided to each group: high FC ratio (35:65) with low-energy concentrate (HFC-LEC), high FC ratio with high-energy concentrate (HFC-HEC), and low FC ratio (25:75) with high-energy concentrate (LFC-HEC). After 10 d of feeding the diets, the CH4 concentrations for all steers were measured and analyzed in duplicate according to the protocol established in experiment 1. In experiment 1, the mean correlation coefficient between the CH4 concentration from respiration and eructation was highest when a combination of two normal distributions was assumed (r = 0.79). The most appropriate measurement times were as follows: 2 h and 1 h before, and 1 h and 2 h after morning feeding. Compared with LFC-HEC, HFC-LEC showed 49% and 57% higher CH4 concentrations in exhaled gas from respiration and eructation (P0.01). In conclusion, the LMD method can be applied to evaluate differences in CH4 emissions in cattle using the protocol established in this study.The hand-held laser methane detector (LMD) technique has been suggested as a potential method for measuring methane (CH4) emissions from enteric fermentation of ruminants in the field. This study aimed to establish a standard procedure for using LMD to assess CH4 production in cattle and evaluate the efficacy of the protocol to detect differences in CH4 emissions from cattle fed with diets of different forage-to-concentrate (FC) ratios which is known to affect CH4 emissions.

The CH4 concentrations for all steers were measured in duplicate according to the protocol established in experiment 1. HFC-LEC showed 49% and 57% higher CH4 concentrations in exhaled gas from respiration and eructation, respectively (P0.01), than LFC-HEC. In conclusion, the LMD method can be applied to evaluate differences in CH4 emissions in cattle using the protocol established in this study.

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.

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.

Background Supragastric belching (SGB) may play a role in the pathophysiology of proton pump inhibitors (PPIs)-refractoriness in gastroesophageal reflux disease (GERD). SGB may be present in up to 40% of reflux symptoms in PPI-refractory GERD. Most reports on SGB have come from Western countries, and little is known about the prevalence and relevance of SGB in Asian refractory GERD patients. This study aimed at comparing the role of SGB in GERD patients in Japan and the UK. Methods We re-analyzed impedance-pH monitoring tracings from patients who were referred to tertiary centers in Japan and the UK due to PPI-refractory reflux symptoms. The prevalence of excessive SGB and the impact of SGB on reflux symptoms were compared between the two countries. Results Impedance-pH tracings from124 Japanese and 83 British patients were re-analyzed. Japanese patients were significantly younger and had smaller body mass index than the British (P P = 0.006). Logistic regression analysis showed that the geographical/cultural difference was the only factor associated with the different prevalence of SGB (odds ratio; 2.91, 95% CI 1.09–7.73, P = 0.032). SGB were related to typical reflux symptoms very rarely in Japan [0% (0–4.9)] compared to the UK [35% (0–54.1)] (P = 0.071). Conclusions The prevalence of SGB and their impact on reflux symptoms is significantly lower in Japan compared to the UK. The difference is not related to reflux parameters but might come from ethnic/cultural factors to be further characterized.

Background Functional dyspepsia (FD), belching disorders (BD) and functional heartburn (FH) are the three most common upper functional gastrointestinal disorders (FGID) in IBS patients. FD is known to exert deleterious effects on health-related quality of life (HRQoL) and the psychological status of IBS patients; however, the impact of overlapping BD and FH on anxiety, depression and HRQoL of IBS patients remains unknown. This cross-sectional study was conducted to investigate the impact of overlapping FD, BD and FH on anxiety, depression and HRQoL in patients with IBS. Methods This study enrolled 319 consecutive outpatients with IBS from 2 tertiary hospitals in Beijing and Shijiazhuang of China. IBS, FD, BD and FH were diagnosed using the Rome III Criteria. Hospital Anxiety and Depression Scale and a 36-item Short-Form Health Survey (SF-36) were used to assess the psychological distress and HRQoL of patients respectively. Results Among the 319 patients with IBS, the IBS subtypes were diarrhoea (67%), constipation (16%), unsubtyped (12%) and mixed (5%). These IBS patients were further classified into IBS + FD, IBS + BD/FH (BD and/or FH), IBS + FD + BD/FH, or IBS only according to the patients’ overlapping upper GI symptoms. IBS+FD patients reported higher levels of anxiety than IBS+BD/FH and elevated depression scores than IBS only patients (P Conclusions Among the diarrhoea-prevalent IBS patients, those with concomitant FD experienced more psychological distress and demonstrated poorer physical HRQoL. Overlapping FD + BD/FH is a significant predictor of worse mental and physical HRQoL for IBS patients. The impact of concomitant BD and FH on the psychological status and HRQoL of IBS patients was limited. These findings implied that the overlapping upper FGIDs in IBS might be treated distinctively when developing comprehensive management strategies for IBS treatment.

BACKGROUND/AIMS Irritable bowel syndrome (IBS) is an important health problem that presents serious social burdens and high costs. Our study investigated the efficacy of synbiotic (Bifidobacterium lactis B94 with inulin), probiotic (B. lactis B94), and prebiotic (inulin) treatment for IBS in a pediatric age group. MATERIAL AND METHODS This study was randomized, double-blind, controlled, and prospective in design and included 71 children between the ages of 4 and 16 years who were diagnosed with IBS according to the Rome III criteria. The first group received synbiotic treatment [5×109 colony forming units (CFU) of B. lactis B94 and 900 mg inulin]; the second group received probiotic treatment (5×109 CFU B. lactis B94), and the third group received prebiotic treatment (900 mg inulin) twice daily for 4 weeks. RESULTS Probiotic treatment improved belching-abdominal fullness (p

Chronic gastrointestinal disorders are disruptive to patients physically and psychologically, and benefit from multidisciplinary care, including targeted psychological interventions. This case study details a case of a 42-year-old Caucasian female with idiopathic eructation, who was identified as having psychological contributors to her 3-year history of GI symptoms. Following extensive medical testing, she was diagnosed with excessive, likely supragastric belching and referred for psychological care. She noted initial reticence to psychological approaches but was offered psychoeducation and CBT interventions targeting eructation disorder and anxiety. Although the patient paused treatment after only a single session of psychological contact (including assessment and brief intervention), her GI symptoms effectively resolved with application of anxiolytic breathing, psychoeducation, and other cognitive behavioral techniques, suggesting rapid efficacy of CBT interventions, when diligently applied.

Upper esophageal sphincter (UES) function has been extensively studied in the context of swallowing and antegrade bolus transit, but relatively little attention has been paid to its retrograde function to facilitate belching. Indeed, prior to 2019, there were only three case reports in the world literature of individuals with a physiologically demonstrated inability to belch due to failure of the UES to relax after gas venting from the stomach and ensuing low-pressure esophageal distention. In this minireview, that disorder is termed retrograde UES dysfunction (R-UESD). The associated symptom complex includes some combination of chest pain, gurgling noises in the chest, bloating, nausea, hiccups, and flatulence. The obscurity of R-UESD has recently been challenged by two large series published in the ENT literature of circumstantially demonstrated R-UESD that was resolved by botulinum toxin (BT) injection to the cricopharyngeus. The field has now further advanced with the publication in this issue of the Journal by Oude Nijhuis et al. of 8 cases of R-UESD demonstrated by high-resolution impedance manometry (HRIM) with a provocative challenge of carbonated water. These individuals were also treated with BT and at 3-month follow-up had both an encouraging symptomatic response and HRIM demonstrated resolution of R-UESD.

Background The relationship between bothersome symptoms and gastric pressure or CO2 injection volumes in drug-resistant functional dyspepsia (FD) patients remains unknown; therefore, this relationship was examined in drug-resistant FD and non-FD patients. Methods Thirty drug-resistant FD patients and 30 non-FD patients were recruited. Gastric pressure was assessed using an external pressure transducer, and the CO2 injection volume was measured using an endoscopic CO2-supplied device and flow meter. The following variables were examined: gastric pressure at baseline and gastric pressure and the CO2 injection volume when patients initially felt abdominal tension and bothersome symptoms following the CO2 injection. The relationship between belching and bothersome symptoms was also investigated. Results No significant differences were observed in basal gastric pressure between the groups. Initial and bothersome symptoms in the upper abdomen in drug-resistant FD patients developed at a significantly lower gastric pressure and significantly smaller CO2 injection volume than in non-FD patients. The frequency of belching was significantly lower in the drug-resistant FD group than in the non-FD group. Conclusion Bothersome symptoms in drug-resistant FD patients develop at a lower gastric pressure and smaller CO2 injection volume than in non-FD patients. These patients also had difficulties with belching.

Background and aims: Gastric bypass surgery effectively treats obesity; however, its association with belching, which occurs in other bariatric surgeries, remains unclear. Hence, we aimed to evaluate belching occurrence after gastric bypass surgery. Methods: We enrolled 12 healthy volunteers and 17 patients (12 and 5 underwent Roux-en-Y gastric bypass and mini-gastric bypass surgeries 24 (18–54) months prior, respectively). Gastrointestinal symptoms were assessed. Gastroscopy was performed, followed by the 24-hour pH-impedance analysis. Results: Age and sex were not statistically different between the two groups (P > 0.05). Patients had a significantly higher mean DeMeester score than the healthy controls (9.11 ± 19.40 vs. 6.04 ± 5.60, P = 0.048), but the pathologic acid reflux (DeMeester score > 14) rate was similar in both groups (11.8% vs. 8.3%). Regarding the impedance, symptom-association probability was positive in 11.8% of patients. The patients also had higher alkaline reflux rates (6% vs. 0%); additionally, 50% of them experienced belching based on the questionnaire, and 25% had esophagitis based on gastroscopy. Furthermore, patients had a significantly higher number of gas reflux (123.24 ± 80 vs. 37.2 ± 21.5, P = 0.001) and supragastric/ gastric belches (182 ± 64/228 ± 66.69 vs. 25.08 ± 15.20/12.17 ± 17.65, P = 0.001). Supragastric belching was more frequent than gastric belching in the controls, whereas gastric belching was more frequent in the patients. Conclusion: Belching increases after gastric bypass surgery in a long-term period. Gastric belching was more frequent than supragastric belching in these patients.

Increased SGB is currently more often recognized not only in patients with belching as a main symptom, but also in patients with reflux like symptoms that are refractory to PPI treatment or patients with reflux hypersensitivity. Detection of increased SGB during analysis of impedance-pHmetry can help to better understand the pathophysiology of symptoms in individual patients and to provide more focused and specific treatment. At the moment, the most efficient treatments for increased SGB are CBT and Speech therapies, pharmacological treatment being less effective and prone to mild secondary effects. In this issue of Neurogastroenterology and Motility, Punkinnen et al demonstrate, in controlled clinical trial, that behavioral therapy was superior to follow-up without intervention in patients with SGB. We present a critical review of the different treatment modalities currently available for patients with pathological SGB.

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.

Introduction: Although inability to belch has previously been linked to dysfunction of the upper esophageal sphincter (UES), its underlying pathogenesis remains unclear. Our aim was to study mechanisms underlying inability to belch and the effect of UES botulinum toxin (botox) injections in these patients. Methods: We prospectively enrolled consecutive patients with symptoms of inability to belch. Patients underwent stationary high-resolution impedance manometry (HRIM) with belch provocation and ambulatory 24-h pH-impedance monitoring before and 3 months after UES botox injection. Results: Eight patients (four males, age 18–37 years) were included. Complete and normal UES relaxation occurred in response to deglutition in all patients. A median number of 33(15–64) gastroesophageal gas reflux episodes were observed. Despite the subsequent increase in esophageal pressure (from −4.0 [−7.7–4.2] to 8 [3.3–16.1] mmHg; p

The timing of sodium bicarbonate (NaHCO3) supplementation has been suggested to be most optimal when coincided with a personal time that bicarbonate (HCO3–) or pH peaks in the blood following ingestion. However, the ergogenic mechanisms supporting this ingestion strategy are strongly contested. It is therefore plausible that NaHCO3 may be ergogenic by causing beneficial shifts in the strong ion difference (SID), though the time course of this blood acid base balance variable is yet to be investigated. Twelve highly trained, adolescent swimmers (age: 15.9 ± 1.0 years, body mass: 65.3 ± 9.6 kg) consumed their typical pre-competition nutrition 1–3 hours before ingesting 0.3 g∙kg BM-1 NaHCO3 in gelatine capsules. Capillary blood samples were then taken during seated rest on nine occasions (0, 60, 75, 90, 105, 120, 135, 150, 165 min post-ingestion) to identify the time course changes in HCO3–, pH, and the SID. No significant differences were found in the time to peak of each blood measure (HCO3–: 130 ± 35 min, pH: 120 ± 38 min, SID: 98 ± 37 min; p = 0.08); however, a large effect size was calculated between time to peak HCO3– and the SID (g = 0.88). Considering that a difference between time to peak blood HCO3– and the SID was identified in adolescents, future research should compare the ergogenic effects of these two individualized NaHCO3 ingestion strategies compared to a traditional, standardized approach.

Excessive belching is frequently reported in adult patients with gastro-oesophageal reflux disease (GORD) and dyspepsia. Although postprandial gastric belching (GB) is considered a physiological mechanism for gastric venting, supra-gastric belching (SGB) is considered a distinct behavioural disorder. We aimed to define the prevalence of different types of belching and its association with reflux disease in paediatric patients.We retrospectively analysed reflux monitoring studies from 287 patients (median age: 7.0 years; interquartile range 3.0-11.3 years) with a suspicion of GORD. Based on oesophageal acid exposure time (AET) patients were divided in 3 groups: (a) physiological AET, (b) borderline AET and (c) pathological AET. MII-pH studies were manually edited and reflux disease parameters were measured together with quantification of GB and SGB.Two hundred one children (70.0%) had physiological AET (median: 0.8; interquartile range 0.3-1.6), 52 (18.1%) had borderline AET (median: 4.2; interquartile range 3.4-5.3) and 34 (11.9%) had pathologic AET (median: 10.7; interquartile range 9.1-14.2). Gastric belching was observed in all studies. Gastric belching related reflux was more frequently observed in patients with borderline and pathological AET (p0.001). This was more common in older children. SGB were observed in only 7 (2.4%) children (age range: 8-17years) in our population and all patients had Physiological AET. Only 3 (1%) patients had pathological number of SGB (13/24 h).Gastric belching related reflux is observed in children with increased AET. SGB is very rare in the paediatric population.

Background Aerophagia is a common functional gastrointestinal disorder among children. The disease leads to symptoms related to air in the intestine leading to burping, abdominal distension, and excessive flatus. We aimed to perform a systematic review and a meta-analysis to assess the epidemiology of aerophagia in children. Methods We conducted a thorough electronic databases (MEDLINE, EMBASE, PsycINFO and Web of Science) search for all epidemiological surveys conducted in children on aerophagia. All selected studies were assessed for their scientific quality and the extracted data were pooled to create a pooled prevalence of aerophagia. Results The initial search identified 76 titles. After screening and in depth reviewing, 19 studies representing data from 21 countries with 40129 children and adolescents were included in the meta-analysis. All studies have used standard Rome definitions to diagnose aerophagia. The pooled prevalence of aerophagia was 3.66% (95% Confidence interval 2.44–5.12). There was significant heterogeneity between studies [I2 98.06% with 95% Confidence interval 97.70–98.37). There was no gender difference in prevalence of aerophagia in children. The pooled prevalence of aerophagia was highest in Asia (5.13%) compared to other geographical regions. Conclusion In this systematic review and meta-analysis, we found aerophagia has a significant prevalence across the world.

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.

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

Case series This is retrospective case series involving 72 patients who presented with symptoms associated with inability to burp. The following symptoms was described by almost all the patients; retrosternal pain after eating or drinking, bloating feeling in the stomach, gurgling noise in the throat, excessive flatulence. These symptoms are worse with fizzy/carbonated drinks and beer. A full clinical history and examination plus endoscopic and in some cases barium a swallow radiological investigation was done. Procedure The surgery was performed under a general anaesthesia for all cases. Suspension pharyngoscopy in supine position using a Weerda diverticuloscope to identify the cricopharyngeal bar muscle. High dose of botulinum toxin A (botox) 100 iu was injected into the cricopharynxgeus muscle under a general anaesthesia. Results A total of 72 patients were diagnosed and undergone surgery between November 2016 and December 2020. There were 50 male and 22 female patients. Their average age was 30 (range 18–68 years old). All patients were able to burp again within first 4 weeks of the injection. This persisted even after the Botox worn off beyond the 3 months in 96% of cases. The average follow-up was 24 months post injection with longest follow-up 48 months (range 1–48 months). Conclusion The author reported a new condition of inability to burp due to failure of the cricopharyngeal sphincter to relax spontaneously and outcome of treatment using botulinum toxin A injection into the cricopharyngeus muscle. It is expected that the paralysing action of botulinum toxin injection last approximately 3 months. However, this group of patients seem to be cured even after the effect of the botox is worn off. The author therefore postulated that there might me some neural dysfunction that inhibits the brain to send signals to the cricopharyngeal sphincter to initiate burping. Once burping is re-established with the help of botox injection, spontaneous burping seems to occur and sustained even after the botox is worn off.
