Eructo, un síntoma que debemos tomar en serio / Belching, a symptom to be taken seriously

El eructo es un síntoma frecuente en Pediatría que socialmente está mal considerado y puede tener consecuencias negativas en la calidad de vida del paciente. No obstante, no son muchas las publicaciones pediátricas al respecto. Según su origen, se pueden clasificar como eructos supragástricos o gástricos, con una fisiología distinta y que pueden ser síntomas de patologías subyacentes tanto físicas como psicológicas. Se revisa la fisiología del eructo y el diagnóstico diferencial a propósito de dos casos diagnosticados de eructos supragástricos.Caso clínico 1: varón de 14 años con cuadro de 15 días de eructos hasta 20-30 por minuto, sensación de imputación esofágica y dolor abdominal. El dolor mejora con omeprazol, pero los eructos persisten; se realiza endoscopia y tránsito esofágico superior que resultan normales. Mejora tras logopedia e inicio de técnicas de relajación.Caso clínico 2: varón de 10 años con cuadro de 19 días de eructos de más de 15 por minuto, sin otros síntomas digestivos, pero con sintomatología ansiosa. Mejoría tras tratamiento psicológico.Ambos tipos de eructo presentan una fisiología distinta, de manera que en el eructo supragástrico el aire no proviene del estómago. El esfínter esofágico inferior permanece cerrado. Los dos tipos son distinguibles mediante pH-impedanciometría. Conclusión: una cuidadosa anamnesis puede establecer el diagnóstico de sospecha del origen del eructo antes de recurrir a pruebas complementarias y permite orientar el tratamiento más adecuado para cada paciente.

Belching is a frequent symptom in paediatrics that is negatively perceived in our society and can have a negative impact on the quality of life of patients. However, there is a dearth of data on the subject for the paediatric population. Depending on the origin, belching can be classified as supragastric or gastric, has a different physiology and may be a manifestation of underlying physical or psychological disorders. We review the physiology of belching and the differential diagnosis of 2 cases of supragastric belching.Clinical case 1: male patient aged 14 years presenting with belching of 15 days’ duration at a rate of 20 to 30 burps per minute, sensation of oesophageal impaction and abdominal pain. The pain improved with omeprazole but the belching persisted, the findings of endoscopy and upper oesophageal transit were normal. The patient improved with speech therapy and initiation of relaxation techniques.Clinical case 2: male patient aged 10 years-old male presenting with belching of 19 days’ duration at a rate of more than 15 burps per minute, with no other digestive symptoms but with anxiety symptoms. The patient improved with psychological treatment.The underlying physiology of belching was different in each patient, as in supragastric belching the air does not come from the stomach and the lower oesophageal sphincter remains closed. These 2 types can be differentiated by pH-impedance. Conclusion: A careful anamnesis can establish the suspected diagnosis of the origin of the belching before resorting to diagnostic tests, and can guide the most appropriate treatment for each patient.

Eructation Treated with Single-Session CBT: A Case Illustration.

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.

Management of supragastric belching with cognitive behavioural therapy: factors determining success and follow-up outcomes at 6-12 months post-therapy.

BACKGROUND: Supragastric belching (SGB) has a significant behavioural component. We recently used cognitive behavioural therapy (CBT) to treat SGB. We demonstrated that CBT significantly reduces symptoms and improves quality of life in 50% of patients who had completed treatment. AIMS: To investigate factors associated with successful CBT for SGB and to assess symptoms 6-12 months after completion of CBT METHODS: Records of 39 patients who had completed the CBT protocol were analysed. Per cent pre- to post-treatment change in symptoms was assessed using a visual analogue scale (VAS) score. We evaluated the association between 'pre-treatment' factors and 'during-treatment' factors, and symptomatic outcomes. Symptoms were also assessed 6-12 months after treatment. RESULTS: From 'pre-treatment factors', a lower number of SGBs (P < .01) and lower hypervigilance score (P < .04) were significantly associated with a better outcome. From 'during-treatment factors' a higher CBT 'proficiency score' ([a] acceptance of the explanation that SGB is a behavioural phenomenon [b] detection of a warning signal before belching [c] adherence to the exercises treatment) was associated with a better outcome (P = .001). Multiple regression analysis found that number of SGBs, hypervigilance score and CBT proficiency score were independently associated with outcome (P < .01, P = .01, P < .01). VAS score before CBT (267 ± 79) decreased to 151 ± 88 soon after CBT (P < .001), and the effect persisted at 6-12 months follow-up (153 ± 82). CONCLUSIONS: Lower number of SGBs, lower hypervigilance score and higher proficiency during CBT were associated with better CBT outcome. CBT positive effect lasted for at least 6-12 months post-treatment.

Belching After Biliary Pancreatitis and Laparoscopic Cholecystectomy.

INTRODUCTION: Belching is often reported symptom. It is rarely an isolated disorder and mainly occurs within various gastroduodenal diseases. AIM: The aim is to show the great breadth of clinical symptoms of postcholecystectomy syndrome which should have a multidisciplinary therapeutic approach taking into account all aspects of patient's life. CASE REPORT: We report a case of excessive belching within postcholecystectomy syndrome which disturbs the general psycho-physical condition of the patient, with symptoms of depression and anxiety, and social isolation, which significantly reduces the quality of his life.

[Rumination in a young woman]. / Nuoren naisen ruminaatio eli märehtiminen.

Rumination refers to bringing up undigested or partially digested food mass from the stomach into the mouth to be rechewed and ingested. This manner of digestion is characteristic of e.g. cattle, but exceptional and likely to cause symptoms for humans. This rare malfunction can be traced on the basis of accurate patient history and confirmed at a test meal by manometry and impedance measurement. Regurgitation may in some patients be triggered by gastroesophageal reflux or air suction into the esophagus caused by an unconscious movement of the pancreas. After the condition has been recognized, behavioral therapy should be primarily considered.

Role of a health psychologist in the management of functional esophageal complaints.

Upper gastrointestinal complaints are common among patients in a gastrointestinal clinic. Outside of typical gastroesophageal reflux disease symptoms that are treated with medication, the symptom presentations of esophageal patients, particularly those with functional conditions, are often difficult to treat and account for high health-care utilization. This manuscript describes the role of a health psychologist in the treatment of esophageal disorders using behavioral medicine interventions. Observations over the course of a 1-year period indicate that the sample presents with a relatively low level of psychological distress but reports negative effects of their symptoms on health-related quality of life. Five case examples of commonly treated disorders (globus, non-cardiac chest pain, functional dysphagia, rumination syndrome, supragastric belching) are described to highlight how behavioral treatment can improve patients' symptoms, decrease health-care utilization, and improve overall quality of life in a timely and relatively simple manner. Successful treatment outcomes are associated with a collaborative working alliance between patient, health psychologist, and gastroenterologist. Results indicate the benefit of referring appropriate esophageal patients to a health psychologist with specialization in gastroenterology.

Gas-related symptoms after antireflux surgery.

BACKGROUND: Gas-related symptoms such as bloating, flatulence, and impaired ability to belch are frequent after antireflux surgery, but it is not known how these symptoms affect patient satisfaction with the procedure or what determines the severity of these complaints. We aimed to assess the impact of gas-related symptoms on patient-perceived success of surgery and to determine whether the severity of gas-related complaints after antireflux surgery is associated with objectively measured abnormalities. METHODS: Fifty-two patients were studied at a median of 27 months after antireflux surgery. The influence of gas-related symptoms on their quality of life and satisfaction with surgical outcome was assessed. The rates of air swallows and gastric and supragastric belches before and after surgery were assessed using impedance measurements. RESULTS: Bloating and flatulence were associated with a decreased quality of life and less satisfaction with surgical outcome. Notably, 9 % of the patients would not opt for surgery again due to gas-related symptoms. Antireflux surgery decreased the total number of gastric belches but did not affect the number of air swallows. The severity of gas-related symptoms was not associated with an increased number of preoperative air swallows and/or belches or a larger postoperative decrease in the number of gastric belches. CONCLUSION: Gas-related symptoms are associated with less satisfaction with surgical outcome. The severity of gas-related symptoms is not determined by the number of preoperative air swallows or a more severe impairment of the ability to belch after surgery. Preoperative predictors of postoperative gas-related symptoms therefore could not be identified.

[Symptomatic features and psychosocial factors in patients with belching disorders].

OBJECTIVE: To explore the symptomatic features and psychosocial factors in patients with belching disorders. METHODS: At Peking Union Medical College Hospital Outpatient Clinic from September 2010 to January 2011, 21 consecutive patients with repetitive belching were profiled by symptom questionnaires, including general demographics, spectrum of symptoms, disease course, predisposing factors, previous treatment, psychosocial factors, mental status and personality traits, etc. Pearson's correlation analysis and exact probability were used. RESULTS: Among them, 20 patients fulfilled the Rome III criteria of belching disorders. There were 5 males and 15 females with an age range of (49 ± 10) years. Among them, the belching patterns were daily (n = 18), meal-related (n = 16), spontaneous (n = 15), controllable (n = 16) and symptomatic overlapping (n = 17). The most common symptoms were functional dyspepsia (FD) (n = 13) and gastroesophageal reflux disease (GERD) (n = 11). Sixteen patients experienced mental stimulation/negative events and 13 patients were related to family tension, work stress and overwork. There were 12 patients with anxiety and/or depression and 8 with neurotic personality. The number of overlapping symptoms was related to anxiety states (r = 0.47, t = 2.14, P < 0.05). But the severity of belching was unrelated to with or without depression and anxiety state (P = 0.096). CONCLUSIONS: There are a variety of clinical manifestations in patients with belching disorders. Belching disorders is often related to emotional change and environmental stress and accompanied by abnormal mental and personality characteristics. Belching may be an abnormal behavior reaction to gastrointestinal discomfort symptoms. The psychological and social factors probably play an important role in the pathogenesis of belching disorders.

Eructophilia in bulimia nervosa: a clinical feature.

This report offers the first detailed description of repetitive eructation (belching) in a patient with bulimia nervosa. The case was a man in his 30's with bulimia nervosa characterized by daily bingeing and purging behavior. Detailed assessment revealed repetitive eructation which was construed as a learned behavior precipitated and maintained by aerophagia (air swallowing) secondary to regular binge-eating. Eructation was associated with a strong sense of "relief" that shared a common phenomenology with other purging behaviors. Repetitive eructation was addressed as part of outpatient treatment using a cognitive-therapy approach. Eructation became less frequent during outpatient treatment but the patient disengaged after six sessions. We define a new term "eructophilia" where repetitive eructation takes on an ego-syntonic, self-contained, and autonomous quality which serves as a reinforcing stimulus in itself. Issues of phenomenology and motivating factors are further discussed.

Symptoms associated with dietary fiber supplementation over time in individuals with fecal incontinence.

BACKGROUND: Knowledge about adverse symptoms over time from fiber supplementation is lacking. PURPOSE: The aim of this study was to compare the severity of adverse gastrointestinal (GI) symptoms during supplementation with dietary fiber or placebo over time in adults with fecal incontinence. A secondary aim was to determine the relationship between symptom severity and emotional upset and their association with study attrition and reducing fiber dose. METHODS: Participants (N = 189; 77% female; 92% White; age, M = 58 years, SD = 14 years) with fecal incontinence were randomly assigned to a placebo or a supplement of 16 g total dietary fiber per day from 1 of 3 sources: gum arabic, psyllium, or carboxymethylcellulose. They reported GI symptoms daily during baseline (14 days), incremental fiber dosing (6 days), and 2 segments of steady full fiber dose (32 days total). RESULTS: Severity of symptoms in all groups was minimal. Adjusting for study segment and day, a greater feeling of fullness in the psyllium group was the only symptom that differed from symptoms in the placebo group. The odds of having greater severity of flatus, belching, fullness, and bloating were 1.2-2.0 times greater in the steady dose segment compared with baseline. There was a positive association between symptom severity and emotional upset. Participants with a greater feeling of fullness or bloating or higher scores for total symptom severity or emotional upset were more likely to withdraw from the study sooner or reduce fiber dose. CONCLUSIONS: Persons with fecal incontinence experience a variety of GI symptoms over time. Symptom severity and emotional upset appear to influence fiber tolerance and study attrition. Supplements seemed well tolerated.

Impaired health-related quality of life in patients with excessive supragastric belching.

BACKGROUND: Excessive supragastric belching, sometimes called aerophagia, is a rare behavioural disorder in which patients belch frequently, up to 20 times a minute. This is perceived by the patients as disturbing and interferes with social functioning and is likely to affect quality of life. METHODS: Twenty-one patients [11 male, aged 49 (28-78) years] with supragastric belching were asked to fill in questionnaires regarding the presence and severity of their symptoms, quality of life (short form-36) and the hospital anxiety and depression scale. RESULTS: The most frequently reported symptoms were belching, epigastric discomfort and fullness whereas heartburn, epigastric burning, retrosternal pain, early satiety, nausea and vomiting were hardly mentioned. Compared with normative values, patients showed a decreased health-related quality of life for the domains social functioning (64.3 ± 17.8), mental health (67.4 ± 16.5), vitality (47.6 ± 20.3), bodily pain (58.9 ± 21.7) and general health (44.8 ± 19.8) but not for physical functioning (75.5 ± 21.5) and physical (63.1 ± 40.0) and emotional role (81.0 ± 35.9). The hospital anxiety and depression scale for anxiety (3 iqr 2-4) and/or depression (2 iqr 1-4) were not elevated. CONCLUSION: In patients with excessive supragastric belching, health-related quality of life is significantly impaired, in particular because of impairment of social function and vitality. Furthermore, the symptom pattern observed in these patients does not resemble that of patients with gastro-oesophageal reflux disease or functional dyspepsia and anxiety disorders and depression are not prevalent in these patients.

Psychological factors affect the frequency of belching in patients with aerophagia.

BACKGROUND: In patients with aerophagia and excessive belching an organic cause is seldom found and a psychogenic cause is often suspected. AIM: To investigate the effects of attention and distraction on the frequency of belching in patients with aerophagia. METHODS: In 10 patients with aerophagia, combined esophageal manometry and impedance monitoring was performed for 2 h, consisting of four 30-minute recording periods. Period I: patient unaware that recording had commenced. Period II: patient informed of recording in progress. Period III: distraction by filling in questionnaires. Period IV: no distraction. RESULTS: A total of 1,258 belches was measured, 51 of which were the result of air that escaped from the stomach (gastric belches). A total of 1,207 belches (96%) were events during which air was expelled in the oral direction almost immediately after entering the esophagus from there (supragastric belches). Gastric belches were distributed equally over the first (1.5 [0.5-2.0]), second (1.5 [0.5-2.0]), third (1.0 [0-2.0]), and fourth (1.0 [0-2.0]) recording periods. In contrast, the incidence of supragastric belches increased significantly from 0 (0-32) in period I to 30 (18-60) in period II, after patients were told that recording was started. During period III (questionnaires) the incidence of supragastric belches decreased to 14 (4-30). In period IV the incidence of supragastric belches increased to 21 (10-49). CONCLUSIONS: When patients with excessive belching are unaware that they are being studied or when they are distracted, the incidence of belching is significantly reduced. These findings underline the importance of psychological factors and provide rationale for behavioral therapy.

Behavioral treatment of chronic belching due to aerophagia in a normal adult.

Aerophagia, or excessive air swallowing, is a potential cause of belching, flatulence, bloating, and abdominal pain and may contribute to a worsening of gastrointestinal (GI) disorders. A limited number of published reports of aerophagia treatment indicate that behavioral methods may be of benefit. A case report is presented describing the behavioral treatment of chronic belching due to aerophagia in an adult female. The collaborative application of single-participant design research helped identify open-mouth, diaphragmatic breathing and minimized swallowing as an effective intervention. Belching frequency was reduced from an average rate of 18 per 5-min interval during the baseline period to 3 per 5-min period after treatment. Results were maintained at an 18-month follow-up. Recommendations for the use of a brief treatment protocol with adults referred for chronic belching or other GI complaints attributed to aerophagia are discussed.

Repetitive eructation (belching) in children: is it pathological?

Eructation (belching) is a common symptom encountered in clinical practice. It has a similar mechanism as gastroesophageal reflux disease (GORD), which is transient lower oesophageal relaxation and is generally assumed to be a manifestation of GORD. Repetitive eructation can be distressing and its management can be difficult and challenging. This report highlights this problem in two adolescent children with a comprehensive review and discussion of its etio-pathogenesis.
