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.

A Case of Aerophagia Diagnosed by Multichannel Intraluminal Impedance Monitoring.

Aerophagia is a disorder caused by abnormal accumulation of air in the gastrointestinal tract as a result of repetitive and frequent inflow of air through the mouth. For the diagnosis of this condition, it is difficult to objectively measure the air swallowing. However, multichannel intraluminal impedance monitoring facilitates the differential diagnosis between normal air swallowing and pathologic aerophagia, and can aid in the determination of the frequency and amount of air swallowed. In this report, in addition to a literature review, we describe a case of 36-year-old man with abdominal distension who was diagnosed with aerophagia using esophageal impedance monitoring and was treated with clonazepam.

Aerofagia patológica: uma causa rara de distensão abdominal crônica / Pathologic aerophagia: a rare cause of chronic abdominal distension

Objetivo:Descrever o caso de uma adolescente com aerofagia patológica, uma doença rara causada pela deglutição excessiva e inapropriada de ar, e revisar o tratamento e os diagnósticos diferenciais.Descrição do caso:Menina de 11 anos portadora de retardo mental e cegueira, apresentava problemas comportamentais associados a retardo do desenvolvimento, foi consultada por distensão abdominal persistente por oito meses. Sua história pregressa incluía uma fundoplicatura à Nissen. Tomografia e radiografias abdominais mostravam distensão difusa do trato digestivo por ar, incluindo cólon e delgado. Doença de Hirschsprung foi excluída. A distensão persistiu mesmo após o controle da constipação e era mínima de manhã e máxima à noite. Ruídos audíveis e repetitivos de deglutição de ar foram observados e auscultados. A criança foi tratada farmacologicamente com o diagnóstico de aerofagia patológica associado a distúrbio obsessivo compulsivo, sem sucesso. A paciente foi submetida a gastrostomia descompressiva endoscopia e manteve nutrição oral.Comentários:A aerofagia patológica é uma doença rara e autolimitada em crianças, mas pode ser um problema grave e persistente naquelas com problemas neuropsiquiátricos, nas quais pode causar complicações sérias. Os tratamentos comportamentais e farmacológicos têm pouco sucesso nesse grupo. Casos graves podem precisar de tratamento cirúrgico, principalmente gastrostomia descompressiva.

Objective:To describe an adolescent with pathologic aerophagia, a rare condition caused by excessive and inappropriate swallowing of air and to review its treatment and differential diagnoses.Case description:An 11-year-old mentally impaired blind girl presenting serious behavior problems and severe developmental delay with abdominal distension from the last 8 months. Her past history included a Nissen fundoplication. Abdominal CT and abdominal radiographs showed diffuse gas distension of the small bowel and colon. Hirschsprung's disease was excluded. The distention was minimal at the moment the child awoke and maximal at evening, and persisted after control of constipation. Audible repetitive and frequent movements of air swallowing were observed. The diagnosis of pathologic aerophagia associated to obsessive-compulsive disorder and developmental delay was made, but pharmacological treatment was unsuccessful. The patient was submitted to an endoscopic gastrostomy, permanently opened and elevated relative to the stomach. The distention was resolved, while maintaining oral nutrition.Comments:Pathologic aerophagia is a rare self-limiting condition in normal children exposed to high levels of stress and may be a persisting problem in children with psychiatric or neurologic disease. In this last group, the disease may cause serious complications. Pharmacological and behavioral treatments are ill-defined. Severe cases may demand surgical strategies, mainly decompressive gastrostomy.

EFFECT OF GUM CHEWING ON AIR SWALLOWING, SALIVA SWALLOWING AND BELCHING / Efeito da goma de mascar na deglutição de ar, deglutição de saliva e na eructação

BackgroundEructation is a physiologic event which allows gastric venting of swallowed air and most of the time is not perceived as a symptom. This is called gastric belching. Supragastric belching occurs when swallowed air does not reach the stomach and returns by mouth a short time after swallowing. This situation may cause discomfort, life limitations and problems in daily life.ObjectiveOur objective in this investigation was to evaluate if gum chewing increases the frequency of gastric and/or supragastric belches.MethodsEsophageal transit of liquid and gas was evaluated by impedance measurement in 16 patients with complaint of troublesome belching and in 15 controls. The Rome III criteria were used in the diagnosis of troublesome belching. The esophageal transit of liquid and gas was measured at 5 cm, 10 cm, 15 cm and 20 cm from the lower esophageal sphincter. The subjects were evaluated for 1 hour which was divided into three 20-minute periods: (1) while sitting for a 20-minute base period; (2) after the ingestion of yogurt (200 mL, 190 kcal), in which the subjects were evaluated while chewing or not chewing gum; (3) final 20-minute period in which the subjects then inverted the task of chewing or not chewing gum. In gastric belch, the air flowed from the stomach through the esophagus in oral direction and in supragastric belch the air entered the esophagus rapidly from proximal and was expulsed almost immediately in oral direction. Air swallows were characterized by an increase of at least 50% of basal impedance and saliva swallow by a decrease of at least 50% of basal impedance, that progress from proximal to distal esophagus.ResultsIn base period, air swallowing was more frequent in patients than in controls and saliva swallowing was more frequent in controls than in patients. There was no difference between the medians of controls and patients in the number of gastric belches and supragastric belches. In six patients, supragastric belches were seen at least once during the 20-minute base period. None of the controls had supragastric belches. In the control group, the ingestion of yogurt caused no significant alteration in the number of air swallows, saliva swallows, gastric belches and supragastric belches. In the patient group, there was an increase in the number of air swallows. If the subjects were chewing gum during this 20-minute period, there was an increase in the number of saliva swallows in both groups, without alterations of the number of air swallow, gastric belches and supragastric belches. There was no alteration in the number of the saliva swallows, air swallows, gastric belches and supragastric belches in both groups for subjects who did not chew gum in the 20-40 minute period after yogurt ingestion. When the subjects were chewing the gum, there was an increase in saliva swallows in the control and patients groups and in air swallows in the patients group.ConclusionGum chewing causes an increase in saliva swallowing in both patients with excessive belching and in controls, and an increase in air swallowing in patients with excessive belching 20 minutes after yogurt ingestion. Gum chewing did not increase or decrease the frequency of gastric or supragastric belches.

ContextoEructação é um evento fisiológico que permite a eliminação de gás presente no estômago, geralmente não percebida como sintoma, situação identificada como eructação gástrica. Eructação supragástrica ocorre quando o ar deglutido não vai ao estômago, mas retorna do esôfago imediatamente após ser deglutido; situação que causa desconforto e limitações ao paciente.ObjetivoO objetivo desta investigação foi avaliar se goma de mascar aumenta a frequência de eructação gástrica e/ou supragástrica.MétodosO trânsito de líquido e gás foi avaliado por impedância in 16 pacientes com queixas de eructação excessiva e 15 controles. O diagnóstico de eructação excessiva foi feito tendo em consideração os critérios descritos no Roma III. O trânsito pelo esôfago foi medido por sensores de impedância localizados a 5 cm, 10 cm, 15 cm e 20 cm do esfíncter inferior do esôfago. Os indivíduos foram avaliados sentados em uma cadeira durante um período basal de 20 minutos, outro período de 20 minutos após a ingestão de iogurte (200 mL, 190 kcal), mastigando ou não goma de mascar, e em outro período por mais 20 minutos no qual invertiam o fato de mastigarem ou não goma de mascar. Na eructação gástrica o ar vinha do estômago em direção proximal, e na eructação supragástrica o ar entrou no esôfago e foi imediatamente eliminado em direção proximal. A deglutição de ar foi caracterizada pelo aumento em pelo menos 50% do valor da impedância e a deglutição de saliva pela diminuição em pelo menos 50% do valor da impedância, que progredia da parte proximal do esôfago para a parte distal.ResultadosNo período basal a deglutição de ar foi mais frequente nos pacientes do que nos controles, e a deglutição de saliva mais frequente nos controles do que nos pacientes. Não houve diferenças na mediana entre os resultados de controles e pacientes no número de eructações gástricas e supragástricas. Em seis pacientes ocorreram eructações supragástricas, o que não aconteceu em nenhum controle. Entre os controles a ingestão de iogurte não alterou a frequência de deglutição de ar, deglutição de saliva, eructações gástricas e eructações supragástricas. No grupo de pacientes houve aumento da deglutição de ar. Mastigar a goma durante este período causou aumento da deglutição de saliva, nos dois grupos, sem alterações na frequência de deglutição de ar, eructação gástrica e eructação supragástrica. No período entre 20 e 40 minutos após a ingestão do iogurte, se a pessoa não mascava a goma, não havia mudança na frequência de deglutição de saliva, deglutição de ar, eructações gástricas e eructações supragástricas. Quando a pessoa mascava a goma, houve aumento da deglutição de saliva nos dois grupos e de deglutição de ar no grupo de pacientes.ConclusãoGoma de mascar causa aumento da deglutição de saliva em pacientes com eructações excessivas e controles, e aumento da deglutição de ar em pacientes 20 minutos após a ingestão de iogurte. Goma de mascar não aumenta ou diminui a frequência de eructação gástrica ou eructação supragástrica.

Clonazepam treatment of pathologic aerophagia in children with mental retardation.

PURPOSE: Pathologic aerophagia (PA) may lead to bowel perforation or volvulus in mentally retarded patients. The authors investigated the effects of clonazepam on the management of PA in children with severe to profound mental retardation (MR). METHODS: This study was undertaken as a retrospective case analysis of 21 PA patients with MR who were followed for over 12 months and diagnosed as having PA. Patients were assigned to two management groups, that is, to a clonazepam randomized open-labeled, treatment group or a reassurance group. The following were recorded and analyzed; age, response, remission rate to clonazepam treatment, and the side effect of clonazepam. It was defined positive response (response+) as being symptom-free for a whole week within 1 month of commencing treatment and remission(+) as being symptom-free for a whole month within 6 months of treatment. RESULTS: The average age of the 21 PA children with MR was 10 years and 13 patients were female. Symptom duration before diagnosis of PA was 7 months. Clinical features of the clonazepam-trial group (n=11) and the reassurance group (n=10) were non-significantly different. Response(+) was achieved by 2 patients (18.2%) in the clonazepam-trial group and by no patient in the reassurance group. Remission(+) was achieved by 6 patients (54.5%) in the clonazepam-trial group and by one patient (10%) in the reassurance group (p=0.040). CONCLUSION: When PA children with MR with severe bowel distention are considered for surgical treatment to prevent acute abdomen, a trial of clonazepam could be recommended.
