Introducción: La manometría de alta resolución es la prueba de referencia para el estudio de los trastornos motores esofágicos. Objetivo: Determinar la factibilidad de la manometría de alta resolución para el estudio de las características de los trastornos motores esofágicos. Métodos: Se realizó una investigación descriptiva, transversal, en el Centro Nacional de Cirugía de Mínimo Acceso, entre septiembre de 2018 y diciembre de 2019, en 56 pacientes cubanos con diagnóstico de trastorno motor esofágico por manometría de alta resolución, con edades entre 18 y 80 años, que dieron su consentimiento para participar en el estudio. Se excluyeron pacientes con acalasia esofágica y los trastornos menores de la peristalsis. Las variables incluidas fueron: edad, sexo, diagnósticos manométricos y sus características, síntomas, tipos de unión esofagogástrica, diagnósticos imagenológicos o endoscópicos. Para el análisis de los resultados se empleó el porcentaje, medidas de tendencia central y ji cuadrado de Pearson de homogeneidad, con un nivel de significación p 8804; 0,05 y 95 por ciento de confiabilidad. Resultados: Predominó la contractilidad ausente (39,28 por ciento), el sexo femenino (58,9 por ciento) y la disfagia (66,07 por ciento). A la obstrucción al flujo de la unión esofagogástrica correspondió la media de presión de reposo del esfínter esofágico inferior más alta (43,28 mmHg) y la media de la presión de relación integrada por encima de 15 mmHg (38,88 mmHg). El esófago hipercontráctil presentó media de contractilidad distal integrada elevada (5564,25 mmHg/s/cm). Se comprobó la existencia de contracciones rápidas en el espasmo esofágico distal (media de 21,4 cm/ s). Conclusiones: La manometría de alta resolución es factible de ser empleada para el diagnóstico de los trastornos motores esofágicos(AU)

Introduction: High-resolution manometry is the gold standard for the study of esophageal motor disorders. Objective: A descriptive, cross-sectional research was carried out in el Centro Nacional de Cirugía de Mínimo Acceso, between September 2018 and December 2019, in 56 patients, diagnosed with esophageal motor disorder by high-resolution manometry, aged between 18 and 20 years, who gave their consent to participate in the study. Esophageal achalasia and minor peristalsis disorders were excluded. The variables included were: age, sex, manometric diagnoses and their characteristics, symptoms, types of esophagogastric junction, imaging or endoscopic diagnoses. For the analysis of the results, the percentage, measures of central tendency and Pearson's chi square of homogeneity were used, with a level of statistical significance 8804; 0.05 and 95 percent reliability. Development: Absent contractility (39,28 percent), female sex (58,9 percent) and dysphagia (66,07 percent) predominated. The obstruction to the flow of the esophagogastric junction corresponded to the highest mean resting pressure of the lower esophageal sphincter (43,28 mmHg) and the mean integrated pressure ratio above 15 mmHg (38,88 mmHg). The hypercontractile esophagus presented mean high integrated distal contractility (5564,25 mmHg/s/cm). Rapid contractions were found in distal esophageal spasm (mean 21,4 cm/s). Conclusions: High resolution manometry was feasible to be used for the diagnosis of major esophageal motor disorders(AU)

Distúrbios funcionais esofágicos na avaliação pré-operatória de cirurgia bariátrica / Esophageal functional disorders in the pre-operatory evaluation of bariatric surgery

ABSTRACT BACKGROUND: Obesity is an independent risk factor for esophageal symptoms, gastroesophageal reflux disease (GERD), and motor abnormalities. When contemplating bariatric surgery, patients with obesity type III undergo esophagogastroduodenoscopy (EGD) and also esophageal manometry (EMN), and prolonged pHmetry (PHM) as part of their pre-operative evaluation. OBJECTIVE: Description of endoscopy, manometry and pHmetry findings in patients with obesity type III preparing for bariatric surgery, and correlation of these findings with the presence of typical GERD symptoms. METHODS: Retrospective study in which clinical symptoms of GERD were assessed, focusing on the presence of heartburn and regurgitation. All patients underwent EMN, PHM and most of them EGD. RESULTS: 114 patients (93 females-81%), average age 36 years old, average BMI of 45.3, were studied. Typical GERD symptoms were referred by 43 (38%) patients while 71 (62%) were asymptomatic. Eighty two patients (72% of total) underwent EGD and 36 (42%) evidenced esophageal abnormalities. Among the abnormal findings, hiatal hernia was seen in 36%, erosive esophagitis (EE) in 36%, and HH+EE in 28%. An abnormal EMN was recorded in 51/114 patients (45%). The main abnormality was a hypotensive lower esophageal sphincter (LES) in 32%, followed by ineffective esophageal motility in 25%, nutcracker esophagus in 19%, IEM + hypotensive LES in 10%, intra-thoracic LES (6%), hypertensive LES (4%), aperistalsis (2%) and achalasia (2%). Among the 43 symptomatic patients, 23 (53%) had abnormal EMN and 31/71 asymptomatic cases (44%) also presented this finding (P=0.30). PHM showed abnormal reflux in 60/114 patients (53%), with a predominance of bi-positional reflux (42%), followed by supine reflux (33%) and upright reflux (25%). Abnormal PHM was found in 26/43 symptomatic cases (60%) and also among 34/71 asymptomatic cases (48%) (P=0.19). CONCLUSION: Manometric abnormalities were common in obesity type III patients, the most frequent being hypotensive LES, followed by IEM. Most patients were asymptomatic. There was no correlation between the finding of motor abnormalities and the presence of symptoms. More than half the patients had abnormal reflux at PHM. We found no significant correlation between abnormal reflux and the presence of symptoms.

RESUMO CONTEXTO: A obesidade é fator de risco independente para sintomas esofagianos, doença do refluxo gastroesofágico (DRGE) e alterações motoras. Pacientes com obesidade tipo III, candidatos à cirurgia bariátrica foram submetidos a endoscopia digestiva alta (EDA) e também realizaram esofagomanometria (EMN) e pHmetria prolongada (PHM) como parte da avaliação pré-operatória. OBJETIVO: Em um grupo de pacientes com obesidade tipo III em pré-operatório de cirurgia bariátrica, descrever os achados endoscópicos, manométricos e pHmétricos, correlacionando-os com a presença de sintomas típicos de DRGE. MÉTODOS: Estudo retrospectivo, de pacientes com obesidade tipo III, candidatos a cirurgia bariátrica. A avaliação clínica focalizou a presença de sintomas típicos de DRGE (pirose/regurgitação); todos foram submetidos a EMN, PHM e a maior parte à EDA, realizada previamente. RESULTADOS: Foram incluídos 114 pacientes, 93 (81%) do sexo feminino, média de idade de 36 anos e IMC médio de 45,3. Sintomas típicos de refluxo foram referidos por 43 (38%) pacientes e 71 (62%) eram assintomáticos. EDA foi realizada por 82 (72%) pacientes, havendo anormalidades esofagianas em 36 (42%). Entre os anormais, havia hérnia hiatal (HH) em 36%, esofagite erosiva (EE) em 36% e HH + EE em 28%. A EMN foi anormal em 51/114 (45%). Entre os anormais, predominou o esfíncter esofagiano inferior (EEI) hipotenso em 32%, seguido por motilidade esofagiana ineficaz (MEI) em 25%, esôfago em quebra-nozes (19%), EEI hipotenso + MEI (10%), EEI intra-torácico (6%), EEI hipertenso (4%), aperistalse (2%) e acalasia (2%). Dentre os 43 sintomáticos, 23 (53%) apresentavam EMN anormal, sendo que em 31 dos 71 (44%) assintomáticos a EMN também era anormal (P=0,30). A PHM revelou refluxo anormal em 60 (53%) pacientes. Predominou o refluxo anormal biposicional (42%) seguido do refluxo supino (33%) e refluxo ereto (25%). Dentre os 43 pacientes sintomáticos, 26 (60%) apresentavam PHM anormal, sendo que em 34 dos 71 assintomáticos a PHM também era anormal (48%) - P=0,19. CONCLUSÃO: Alterações manométricas foram comuns em obesidade tipo III, sendo as mais frequentes o EEI hipotenso, seguida de motilidade ineficaz. A maioria dos pacientes era assintomática. Mais da metade dos pacientes apresentou refluxo anormal à PHM. Não houve diferença significativa entre o achado de refluxo anormal e a presença de sintomas. Não houve relação entre o achado de alterações motoras e a presença de sintomas.

La manometría de alta resolución en los trastornos motores del esófago Introducción en Cuba / High-resolution manometry for diagnosis of esophageal motor disorders. Introduction in Cuba

RESUMEN: Introducción: La manometría esofágica de alta resolución se considera a nivel internacional como un método óptimo para el diagnóstico de los trastornos motores del esófago, de alta especificidad y sensibilidad. Dada la reciente introducción de la técnica en Cuba, se necesita demostrar su utilidad en nuestro país, donde no existe grado de conocimiento previo sobre cuáles son los parámetros de normalidad, así como los diagnósticos de alta resolución más frecuentes. Objetivo: Determinar la utilidad de la manometría esofágica de alta resolución como estudio diagnóstico para los trastornos motores del esófago en Cuba. Métodos: Se diseñó una investigación aplicada, de desarrollo, realizada en el Centro Nacional de Cirugía de Mínimo Acceso, en La Habana, entre junio de 2017 y junio de 2019, en pacientes a los que se les realizó una manometría esofágica. El universo de pacientes fue 611, a quienes se les registraron las variables en estudio. Resultados: De las 611 manometrías esofágicas, 356 correspondían a mujeres (58,3 por ciento) y 255 a hombres (42,7 por ciento), con un promedio de edad de 47, 44 años respectivamente. La motilidad inefectiva fue el trastorno motor más frecuente (32,73 por ciento). En los pacientes con Enfermedad por Reflujo Gastroesofágico, el principal daño de la barrera antirreflujo fue la presencia de relajaciones transitorias del esfínter esofágico inferior. Predominó la Acalasia tipo II (5,23 por ciento). En estos pacientes se registraron valores de Presión de relajación integrada (IRP) por encima de 21. Conclusiones: Se establecieron valores aplicables a pacientes cubanos, que permiten establecer el diagnóstico por alta resolución(AU)

ABSTRACT Introduction: High-resolution esophageal manometry is considered internationally as an optimal method for diagnosis of esophageal motor disorders. Given the recent introduction of the technique in Cuba, it is necessary to demonstrate its usefulness in our country where there is no prior knowledge about the most frequent parameters of normality and high resolution diagnoses. Objective: To determine the usefulness of high-resolution esophageal manometry as a method for the diagnosis of esophageal motor disorders in Cuba. Material and methods: An applied developmental research was designed and carried out at the National Center for Minimal Access Surgery in Havana between June 2017 and June 2019. The study included patients in whom esophageal manometry was performed. The universe consisted of 611 patients and the variables used in the study were recorded. Results: Of the 611 patients who underwent esophageal manometry, 356 were women (58.26 percent) and 255 were men (42.73 percent), with an average age of 47 and 44 years, respectively. Ineffective motility was the most frequent motor disorder (32,73 percent). In patients with Gastroesophageal Reflux Disease, the main damage of the antireflux barrier was the presence of transient lower esophageal sphincter relaxations. Type II achalasia predominated (5,23 percent). In these patients, integrated relaxation pressure (IRP) values above 21 were recorded. Conclusions: Values applicable to Cuban patients that allow to establish a high-resolution diagnosis were established(AU)

Study of etiology and esophageal motility characteristics of esophagogastric junction outlet obstruction patients / 北京大学学报(医学版)

OBJECTIVE@#To analyze the causes of the esophagogastric junction outlet obstruction (EGJOO) patients, to discuss the differences of the clinical manifestation and esophageal motility characteristics between the anatomic EGJOO (A-EGJOO) and functional EGJOO (F-EGJOO) subgroups, and to search the diagnostic values of the specific metrics for differentiating the subgroups of EGJOO patients.@*METHODS@#For the current retrospective study, all the patients who underwent the esophageal high resonance manometry test were retrospectively analyzed from Jan 2012 to Oct 2018 in Peking University Third Hospital. The EGJOO patients were enrolled in the following research. The clinical characteristics, such as symptoms and causes of the patients were studied. Then the patients were divided into two subgroups as A-EGJOO subgroup and F-EGJOO subgroup. The clinical symptoms and the main manometry metrics were compared between these two subgroups. The significant different metrics between the two groups were selected to draw receiver operating characteristic (ROC) curves and the diagnostic values were analyzed in differentiating the A-EGJOO and F-EGJOO subgroups.@*RESULTS@#The most common symptom of EGJOO was chest pain or chest discomfort (30.63%), then the dysphagia (29.73%), and acid regurgitation/heartburn (27.03%). Non-erosive reflux disease (36.04%) was the most popular cause for EGJOO, then the reflux esophagitis (17.12%). Besides the intra-EGJOO and extra-EGJOO lesions, the connective tissue disease (6.31%) and central nervous diseases (2.70%) were found to be the etiology of EGJOO. The causes of the rest 19 EGJOO were unknown. A-EGJOO patients presented significantly higher intra bolus pressure (IBP) than that of F-EGJOO [6.80 (5.20, 9.20) mmHg vs. 5.10 (3.10, 7.60) mmHg, P=0.016]. The area under curve of IBP was 0.637. When IBP≥5.15 mmHg, the sensitivity was 78.60% and specificity 50.70% to differentiate A- or F-EGJOO.@*CONCLUSION@#Chest pain or chest discomfort was the most common symptom in EGJOO patients. Besides the intraluminal structural disorders, the extra-luminal causes were found in EGJOO patients. A-EGJOO presented higher IBP than that of F-EGJOO patients. The cutoff value of IBP to differentiate A-EGJOO from EGJOO was 5.15 mmHg with sensitivity 78.06% and specificity 50.70%. However for the low area under curve, the diagnostic value of IBP was limited.

¿El reflujo gastroesofágico y la aspiración de contenido gástrico están implicados en la etiopatogenia y la progresión de la fibrosis pulmonar idiopática? / Does gastroesophageal reflux and gastric content aspiration have some role in the pathogenesis and progression of Idiopathic Pulmonary Fibrosis?

Resumen El reflujo gastroesofágico (RGE) y la aspiración oculta de contenido digestivo están probablemente implicados en la etiopatogenia y progresión de la fibrosis pulmonar idiopática (FPI). Los mecanismos patogénicos involucrados son la disminución de la distensibilidad pulmonar y el consiguiente aumento de la presión negativa intratorácica durante la inspiración, así como la disminución de los mecanismos de control de la motilidad esofágica o del tono del esfínter esofágico inferior. La prevalencia de RGE y anomalías de la motilidad esofágica están aumentadas en los pacientes con FPI comparado con la población general. Entre los pacientes con FPI, el 67-76% demostraron exposición anormal al contenido ácido en el esófago. Sin embargo, no hubo relación entre la gravedad del RGE y la gravedad de la FPI. Los estudios que han examinado el tratamiento antirreflujo en esta población han sido escasos. Incluso, algunos datos sugieren que el tratamiento antiácido puede ser perjudicial en algunos pacientes con esta condición. Después de analizar toda la evidencia relevante encontrada hasta la fecha, concluimos que no se puede establecer una relación causal entre el RGE, la aspiración del contenido gástrico y la patogénesis de la FPI. Además, existe escasa evidencia clínica que haya examinado el tratamiento antirreflujo en pacientes con fibrosis pulmonar idiopática.

ABSTRACT Gastroesophageal reflux (GERD) and hidden aspiration of gastric contents are probably involved in the pathogenesis and progression of idiopathic pulmonary fibrosis (IPF). The pathological mechanisms involved are decreased pulmonary distensibility and consequent increase of intrathoracic negative pressure during inspiration, as well as decreased control mechanisms of esophageal motility or lower esophageal sphincter. The prevalence of GERD and oesophageal dysmotility was higher in patients with IPF as compared with general population. Among patients with IPF, 67-76% demonstrated abnormal oesophageal acid exposure. However, no relationship was demonstrated between severity of GERD and severity of IPF. Data are scant on outcomes of antireflux treatment in patients with IPF. Actually, some data suggests that antacid treatment may be deleterious in some IPF patients. After analyzing all the relevant evidence found to date, a causal relationship between GERD, gastric content aspiration and IPF pathogenesis cannot be established. There is scant evidence examining antireflux treatment in idiopathic pulmonary fibrosis patients.

Timpanismo em bovinos, secundário à obstrução esofágica por citrus limon (limão siciliano) / Bloat in cattle secondary to esophageal obstruction by citrus limon (sicilian lemon)

Timpanismo ruminal consiste na distensão acentuada do rúmen e retículo, devido a incapacidade do animal em expulsar gases produzidos durante o processo fisiológico da fermentação. O timpanismo pode ser ocasionado de forma primária, por formação de espuma estável, ou secundária, devido a anormalidades funcionais e/ou físicas que interferem na eructação. Nesse trabalho, são descritos os aspectos epidemiológicos, clínicos e anatomopatológicos da ocorrência de timpanismo secundário em bovinos, decorrente da obstrução esofágica aguda por limões sicilianos. Cinco bovinos, de um lote de 210, foram afetados. Os bovinos eram suplementados com resíduo de tangerina (Citrus reticulata) no cocho e na última carga desse subproduto, havia limões sicilianos inteiros misturados ao resíduo. Os cinco animais afetados eram da raça Aberdeen Angus e tinham entre 12-24 meses de idade. Todos apresentaram sinais clínicos caracterizados principalmente por mucosas cianóticas, grave timpanismo, desconforto abdominal, acentuada dispneia e taquicardia, atonia ruminal, desidratação, decúbito e morte. O curso clínico variou entre 24 a 48 horas. Na necropsia, os cinco bovinos apresentavam grave obstrução esofágica por limões nas porções: cranial (logo após a laringe [1/5]), porção medial (entrada do tórax [1/5]) e final (próximo ao cárdia [3/5]). Nas áreas de oclusão, observou-se extensa necrose e ulceração da mucosa esofágica. O conteúdo ruminal dos bovinos estava seco e misturado com limões inteiros. No esôfago de dois animais havia linha de timpanismo. As lesões histológicas eram visualizadas principalmente no esôfago, na região da obstrução, onde se evidenciaram alterações degenerativas, necróticas e ulcerativas acentuadas no revestimento epitelial.

Ruminal bloat (acute timpany) in ruminants is a marked rumen-reticular distension which results from more gas being produced during the physiologic process of fermentation than is eliminated by eructation. This condition may present itself as either primary timpany due to the formation of stable foam or secondary timpany resulting from functional and/or physical disturbances compromising eructation. This paper describes the epidemiological, clinical, and anatomopathological aspects of acute timpany in cattle secondary to esophageal obstruction by sicilian lemons. Five out of a herd of 210 cattle were affected. Cattle were supplemented with tangerine (Citrus reticulata) residues in a trough. In the last batch of this feed there were whole sicilian lemons mixed with the tangerine residue. The five affected cattle were 12-24 month-old Aberdeen-Angus. All of the five presented clinical signs characterized mainly by cyanotic mucous membranes, severe timpany, abdominal discomfort, marked dyspnea and tachycardia, ruminal atony, dehydration, recumbence and death. Clinical course lasted from 24 to 48 hours. Necropsy findings in the five affected cattle were similar and included complete esophageal obstruction by lemons in the cranial esophagus (immediately cranial to the larynx [1/5]) medial esophagus (at the thoracic inlet [1/5]) and caudal esophagus (close to the cardia [3/5]). At the occluded sites the esophageal mucosa was necrotic and ulcerated. Ruminal content was dried and admixed with whole lemons. In the esophagus o two affected bovine a bloat line was observed. Histological lesions were observed mainly in the esophagus at the sites of obstruction and consisted of marked degenerative, necrotic and ulcerative changes in the esophageal mucosal epithelium.

Jackhammer Esophagus Treated by a Peroral Endoscopic Myotomy / 대한소화기학회지

A 49-year-old woman visited our hospital with dysphagia and chest pain. In another hospital, she was diagnosed as reflux esophagitis. Although she had taken proton pump inhibitor and prokinetics drugs for a long time, she was not relieved of any symptoms. On the basis of high resolution manometry and endoscopic ultrasonography findings, Jackhammer esophagus was diagnosed. In this patient, peroral endoscopic myotomy (POEM) was performed for long myotomy of thickened circular muscle. During the procedure, there were no significant complications and she was discharged uneventfully. Symptoms were completely improved during three months after POEM. Here, we report on a case of Jackhammer esophagus treated by POEM.

Tratamento endovascular da Sindrome de Quebra-nozes (Nutcracker) / Endovascular treatment of Nutcracker syndrome

A Síndrome do Quebra-nozes se refere a um conjunto de sinais secundários à compressão da veia renal esquerda, mais comumente entre a artéria mesentérica superior e a aorta, levando ao comprometimento do fluxo para a veia cava. O diagnóstico desta síndrome frequentemente é difícil e, por esta razão, o diagnóstico é demorado, em muitos casos. É relatado, nesta publicação, o caso de uma mulher de 51 anos, tratada com sucesso pela embolização da veia ovariana associada ao implante de stent autoexpansível na veia renal esquerda. São discutidos os aspectos técnicos e as dificuldades do procedimento.

Nutcracker syndrome refers to signs and symptoms secondary to compression of the left renal vein, most commonly between the superior mesenteric artery and the aorta, leading to impaired outflow to the vena cava. Diagnosis of this syndrome is often difficult and as result is late in most cases. We report on the case of a 51-year-old woman successfully treated with embolization of the ovarian vein and insertion of a self expandable stent in the left renal vein. Technical details and pitfalls are discussed.

Motilidade esofágica, sintomas, resultado alimentar e perda de peso após derivação gástrica em Y-de-Roux / Esophageal motility, symptoms, food intake and weight loss after Roux-en-Y gastric bypass

RACIONAL: Achados anormais de manometria podem ser encontrados na população obesa. É controverso se a manometria deveria ser usada para escolher a técnica cirúrgica e se a função esofágica poderia prever os sintomas pós-operatórios. OBJETIVO: Correlacionar a motilidade do esôfago com sintomas pós-operatórios, resultado alimentar e perda de peso após a derivação gástrica em Y de Roux. MÉTODO: Cento e catorze pacientes submetidos à derivação foram estudados prospectivamente. Eles não apresentavam sintomas de refluxo gastroesofágico ou doenças que pudessem interferir com a função motora do esôfago. Um ano após a operação foram entrevistados sobre os sintomas e hábitos alimentares. RESULTADOS: A perda do excesso de peso foi de 66,2%. Sessenta pacientes (52,6%) tiveram manometria anormal; quarenta e nove (43%) alterações manométricas no esfíncter inferior do esôfago no pré-operatório; pressão elevada em 18 pacientes (16%) e baixa em 31 (27%). A síndrome de dumping foi encontrada em 27 (23,6%) pacientes e 21 (18,4%) queixaram-se de regurgitação. Resultado alimentar excelente, bom, moderado e pobre esteve presente em 32 (28%), 31 (27,2%), 39 (34,2%), 12 (11,6%) pacientes, respectivamente. A pressão do esfíncter inferior e amplitude de contração do esôfago não se correlacionam com perda do excesso de peso, cuja média foi significativamente maior para os pacientes com hipertensão na amplitude de contração. Regurgitação foi mais frequente em pacientes com hipotonia do esfíncter. Não houve correlação entre dumping e pressão do esfíncter inferior; entre amplitude de contração e dumping ou regurgitação; entre os resultados alimentares e pressão do esfíncter ou amplitude de contração do esôfago. CONCLUSÃO: A manometria esofágica antes da derivação é de importância clínica limitada.

BACKGROUND: Abnormal manometry findings can be found in the obese population. It is controversial if the manometry should be used to choose the adequate operation or if the motility status could predict symptomatic outcomes. AIM: To correlate the esophageal motility with postoperative symptoms, alimentary outcome and weight loss after Roux-en-Y gastric bypass. METHODS: One hundred and fourteen patients were submitted to the operation and were prospectively studied. They had no GERD symptoms or diseases that might interfere with esophageal motor function. One year after surgery patients were interviewed regarding current symptoms and eating habits. RESULTS: Excess weight loss was 66.2 %. Sixty (52.6%) patients had an abnormal manometry. Hypertensive lower esophageal sphincter was found in 18 (16%) patients and hypotonic sphincter in 31 (27%). Dumping syndrome was mentioned by 27 (23.6%) patients and 21 (18.4%) complained of regurgitation. Excellent, good, moderate and poor alimentary outcome was present in 32 (28%), 31 (27.2%), 39 (34.2%), 12 (11.6%) patients, respectively. Sphincter pressure and esophageal amplitude did not correlate with excess weight loss. Its average was significantly higher for patients with hypertensive esophageal amplitude. Regurgitation was more frequent in patients with a hypotensive sphincter. There is no correlation between dumping and sphincter pressure status; between dumping or regurgitation and esophageal amplitude; between alimentary outcomes and sphincter pressure status or esophageal amplitude. CONCLUSION: Esophageal manometry before Roux-en-Y gastric bypass is of limited clinical significance.

What is the rea impairment on esophageal motilty in patients with gastroesophhageal reflux disease?

Context Impairment of esophageal motility is a common finding in patients with gastroesophageal reflux disease (GERD) as reduced lower esophageal sphincter (LES) basal pressure. A very low LES pressure might facilitate the occurrence of more gastroesophageal reflux whereas abnormal esophageal peristalsis may contribute to impaired esophageal clearance after reflux. Objective Evaluate the esophageal motor function of the lower esophageal sphincter and esophageal body in the various forms of gastroesophageal reflux disease. Methods The manometrics records of 268 patients, who had evaluation of the esophageal motility as part of the diagnostic gastroesophageal reflux disease were split into four groups, as follows: 33 patients who had no esophagitis; 92 patients who had erosive esophagitis; 101 patients who had short Barrett's esophagus and 42 patients who had long Barrett's esophagus. Results The group who had long Barrett's esophagus showed smaller mean LES pressure and higher percentage of marked LES hypotonia; in the distal segment of the esophageal body the this group showed higher percentage of marked hypocontractility of the distal segment (<30 mm Hg); this same group showed higher percentage of esophageal motility disorders. Conclusions The most intense esophageal motility disorders and lower pressure of lower esophageal sphincter were noted in the group with long Barrett's esophagus. Those with reflux esophagitis and short Barrett's esophagus had esophageal motility impairment, intermediate among patients with esophagitis and long Barrett's esophagus. Patients with typical symptoms of gastroesophageal reflux but without esophagitis by endoscopy study showed no impairment of esophageal motility. .

Contexto Alteração no peristaltismo esofágico assim como diminuição do tônus basal do esfíncter inferior do esôfago são um achado comum em pacientes com doença do refluxo gastroesofágico. A presença de hipotonia acentuada do esfíncter inferior do esôfago pode facilitar a ocorrência de refluxo gastroesofágico mais intenso e a presença de alteração no peristaltismo esofágico pode contribuir para uma deficiente depuração esofágica. Objetivo Avaliar a função motora do esfíncter inferior do esôfago e do corpo esofágico nas várias formas da doença do refluxo gastroesofágico. Métodos Avaliaram-se os prontuários de 268 pacientes, que realizaram manometria esofágica como parte da investigação diagnóstica da doença do refluxo gastroesofágico. Os pacientes foram distribuidos em quatro grupos: 33 pacientes que não tinham esofagite, 92 pacientes que tinham esofagite erosiva; 101 pacientes que tinham esôfago de Barrett curto e 42 pacientes que tinham esôfago de Barrett longo (grupo EBL). Resultados O grupo dos que tinham EBL, apresentou menor média de pressão do esfíncter inferior do esôfago e maior percentual de hipotonia acentuada do esfíncter inferior do esôfago; no segmento distal do corpo do esôfago, este grupo apresentou maior percentual de hipocontratilidade acentuada (< 30 mm Hg). O grupo dos que tinham EBL apresentou maior porcentagem de distúrbios da motilidade esofágica. Conclusões As alterações mais intensas na motilidade esofágica e no esfíncter inferior do esôfago foram observadas no grupo com EBL. Aqueles com esofagite de refluxo e esôfago de Barrett curto ...

Clinico-pathological Profile of Oesophageal Dysphagia.

Introduction: Dysphagia can cause significant morbidity and mortality, especially in the elderly and the paediatric population. The study was undertaken to determine the clinico-pathological profile of the patients diagnosed with oesophageal dysphagia in a rural tertiary care hospital of India. Methods: This cross sectional, descriptive study was carried out in the ENT Department of Rural Medical College and Pravara Rural Hospital, Loni, Maharashtra. Patients attending the ENT Out Patient Department during 2009 and later diagnosed as cases of oesophageal dysphagia formed the statistical sample. Results: Out of 61 patients, 37 were male and 24 female. Majority of the patients belonged to age group 41-50 years (24.6%), were farmer by occupation (31.1%) and belonged to middle socioeconomic status (34.4%). Pain (throat, retrosternal or epigastric) was the most common (70.5%) presenting complaint. For 39.3% study subjects, the presenting complaint was 3 to 6 months old. Barium swallow study revealed a positive finding in 74.1% (n=40/54) patients, with carcinoma of oesophagus (27.8%) as the most common aetiology, followed by motility disorders and benign strictures. Oesophagoscopy detected lesions in 49 (90.74%) cases and like barium swallow, it also detected carcinoma oesophagus as the most common cause of oesophageal dysphagia. Reflux oesophagitis was the most common form of the oesophagitis and the microbiological examination and culture of samples of 14 patients diagnosed with any form of oesophagitis showed Candida albicans in 21.4%. Conclusion: Dysphagia is a common presenting complaint in the ENT clinic. There is a male preponderance with incidence of malignancy rising with age. Barium swallow may be used as the first line of investigation; however, oesophagoscopy gives a better diagnosis.

Prevalência da doença do refluxo gastroesofágico em pacientes com fibrose pulmonar idiopática / Prevalence of gastroesophageal reflux disease in patients with idiopathic pulmonary fibrosis

OBJETIVO: Determinar a prevalência da doença do refluxo gastroesofágico (DRGE) e sua apresentação clínica, além do perfil funcional do esôfago em pacientes com fibrose pulmonar idiopática (FPI). MÉTODOS: Foram avaliados prospectivamente 28 pacientes com FPI. Os pacientes foram submetidos à esofagomanometria estacionária, pHmetria de 24 h e testes de função pulmonar, assim como responderam a questionários sobre sintomas e qualidade de vida em DRGE. RESULTADOS: A prevalência de DRGE foi de 35,7 por cento. Os pacientes foram divididos em dois grupos: grupo DRGE+ (pHmetria anormal; n = 10), e grupo DRGE- (pHmetria normal; n = 18). No grupo DRGE+, 77,7 por cento dos pacientes apresentavam pelo menos um sintoma típico de DRGE. Nesse grupo de pacientes, 8 (80 por cento) apresentaram refluxo em posição supina, e 5 (50 por cento) apresentaram refluxo exclusivamente nessa posição. Nos grupos DRGE+ e DRGE-, respectivamente, 5 (50,0 por cento) e 7 (38,8 por cento) dos pacientes apresentaram hipotonia do esfíncter esofágico inferior, assim como 7 (70,0 por cento) e 10 (55,5 por cento) apresentaram hipomotilidade esofágica. Não houve diferenças significativas entre os grupos quanto a características demográficas, função pulmonar, apresentação clínica ou achados manométricos. CONCLUSÕES: A prevalência de DRGE nos pacientes com

OBJECTIVE: To determine the prevalence of gastroesophageal reflux disease (GERD) and to evaluate its clinical presentation, as well as the esophageal function profile in patients with idiopathic pulmonary fibrosis (IPF). METHODS: In this prospective study, 28 consecutive patients with IPF underwent stationary esophageal manometry, 24-h esophageal pH-metry and pulmonary function tests. All patients also completed a symptom and quality of life in GERD questionnaire. RESULTS: In the study sample, the prevalence of GERD was 35.7 percent. The patients were then divided into two groups: GERD+ (abnormal pH-metry; n = 10) and GERD- (normal pH-metry; n = 18). In the GERD+ group, 77.7 percent of the patients presented at least one typical GERD symptom. The pH-metry results showed that 8 (80 percent) of the GERD+ group patients had abnormal supine reflux, and that the reflux was exclusively in the supine position in 5 (50 percent). In the GERD+ and GERD- groups, respectively, 5 (50.0 percent) and 7 (38.8 percent) of the patients presented a hypotensive lower esophageal sphincter, 7 (70.0 percent) and 10 (55.5 percent), respectively, presenting lower esophageal dysmotility. There were no significant differences between the groups regarding demographic characteristics, pulmonary function, clinical presentation or manometric findings. CONCLUSIONS: The prevalence of GERD in the patients with IPF was high. However, the clinical and functional characteristics did not differ between the patients with GERD and those without.

[Multiple esophageal diverticules in a case of nutcracker esophagus]

Multiple esophageal diverticula is a rare entity that may be seen in the course of esophageal motor disorders. Herein, I reported a 45 year-old man presented with intermittent chest pain and dysphagia since 20 years ago that exaggerated during the last six months. Barium swallow and upper GI endoscopy revealed multiple diverticula along the esophagus and his esophageal manometry showed high amplitude contractions [>180 mmHg] in distal part of the esophagus that confirmed the diagnosis of nutcracker esophagus

Esofagomanometria e pHmetria esofágica de 24 h em uma ampla amostra de pacientes com manifestações respiratórias / Esophageal manometry and 24-h esophageal pH-metry in a large sample of patients with respiratory symptoms

OBJETIVO: Determinar a prevalência da doença do refluxo gastroesofágico (DRGE) e avaliar o perfil motor esofágico de portadores de manifestações respiratórias encaminhados para avaliação funcional esofágica em um serviço de referência em motilidade digestiva. MÉTODOS: Foram analisados os resultados de esofagomanometria e de pHmetria esofágica de 24 h. O critério de inclusão foi a presença de sintomas respiratórios, acompanhados ou não de sintomas digestivos. RESULTADOS: Dos 1.170 pacientes incluídos no estudo, 602 (51,5 por cento) relataram manifestações digestivas associadas às respiratórias (grupo MRD) e 568 (48,5 por cento), apenas respiratórias (grupo MR). A asma foi diagnosticada em 142 indivíduos no grupo MR (subgrupo MR-A) e em 201 no grupo MRD (subgrupo MRD-A). Dentre os 346 casos de dismotilidade do corpo esofágico, a hipomotilidade esteve presente em 175 (14,3 por cento e 15,6 por cento, respectivamente, no grupos MRD e MR) e hipotonia do esfíncter esofágico inferior (EEI) em 411 (40.3 por cento e 30,2 por cento nos mesmos grupos, respectivamente). A hipotonia se correlacionou com DRGE. A exposição do esôfago distal ao ácido foi marcadamente anormal no período de decúbito. A prevalência de DRGE na amostra total, nos subgrupos MR-A/MRD-A e somente no subgrupo MR-A foi de 39,8 por cento, 44,0 por cento e 35,2 por cento, respectivamente. CONCLUSÕES: A hipotonia do EEI foi a alteração manométrica preponderante, correlacionando-se com DRGE. Embora a DRGE foi mais evidente no grupo MRD, aproximadamente um terço dos pacientes do grupo MR apresentou DRGE (DRGE silencioso). Os achados sugerem a DRGE como possível causa extrapulmonar de sintomas respiratórios crônicos não responsivos à terapêutica convencional.

OBJECTIVE: To determine the prevalence of gastroesophageal reflux disease (GERD) and to evaluate the esophageal motor profile of patients with respiratory symptoms referred to a digestive motility referral center for esophageal function testing. METHODS: The results of esophageal manometry and 24-h esophageal pH-metry were analyzed.The inclusion criterion was presenting respiratory symptoms, with or without accompanying digestive symptoms. RESULTS: Of the 1,170 patients included in the study, 602 (51.5 percent) reported having digestive and respiratory symptoms (DRS group), and 568 (48.5 percent) reported having only respiratory symptoms (RS group). Asthma was diagnosed in 142 patients in the RS group (RS-A subgroup) and in 201 of those in the DRS group (DRS-A). Of the 346 cases of esophageal dysmotility, hypomotility was found in 175 (14.3 percent and 15.6 percent in the DRS and RS groups, respectively), and lower esophageal sphincter (LES) hypotonia was found in 411 (40.3 percent and 30.2 percent, respectively). Hypotonia correlated with GERD. Exposure of the distal esophagus to acid was markedly abnormal in the supine position. The prevalence of GERD in the sample as a whole, the RS-A/DRS-A subgroups and the RS-A subgroup alone was 39.8 percent, 44.0 percent and 35.2 percent, respectively CONCLUSIONS: Hypotonic LES was the most common abnormality and correlated with GERD. Although GERD was more evident in the DRS group, approximately one third of the patients in the RS group also presented GERD (silent GERD). The findings suggest that GERD can be an extrapulmonary cause of chronic respiratory symptoms unresponsive to conventional therapy.

Dolor torácico no cardiaco / Non-cardiac chest pain

El dolor torácico no - cardíaco es una condición relativamente frecuente, que se diagnostica después de una evaluación cardiológica dirigida a las coronarias ha resultado normal. El reflujo gastroesofágico ácido es la causa más frecuente del dolor torácico no cardíaco, y se interpreta como un aumento en la sensibilidad visceral con mucosa hipersensible a la irritación, y potenciada por el estrés. Menos frecuentes son los trastornos motores del esófago como el espasmo difuso del esófago que también se asocia al estrés emocional. Un enfoque terapéutico simple inicial puede ser la administración de inhibidores de la bomba de protones, por un periodo. Si no hay respuesta está indicado efectuar una manometría esofágica y monitoreo por 24 horas del pH intraesofágico. El tratamiento farmacológico está comandado por los hallazgos de estos tests.

Non-cardiac chest pain is a relatively common condition diagnosed following a normal cardiac and coronary evaluation. Abnormal gastro-esophageal acid reflux is the most common condition associated to non - cardiac chest pain. It has been related to visceral hypersensitivity of the esophageal mucosa. Esophageal motility disorders such as diffuse esophageal spasm also relates to stress are less common. An initial simple therapeutic approach is to indicate proton pump inhibitors for a few days. If there is no relief, esophageal manometry and a 24 hour monitoring intra-esophageal pH are indicated.

Esophageal motility disorders in patients with diabetes mellitus

The prevalence of gastrointestinal symptoms seems to be increased in diabetics compared with general population. The aim of this work is to study the esophageal motor abnormalities in diabetic patients to determine whether esophageal motility disorders are related to the symptoms and the clinical status of the patients. The study was conducted on 120 diabetic patients and 20 healthy control divided into-group I: 20 healthy controls, group II: 60 type I diabetic patients, group III: 60 type 2 diabetic patients. They were monitored by laboratory tests-Fundus examination-Abdominal sonography-upper esophagogastric endoscopy-esophageal manometry including lower esophageal sphincter study, esophageal body study, and upper esophageal sphincter study. The data was collected, statistically analyzed using computer program SPSS version nine. There was significant difference between type I and 2 diabetics compared to controls regarding decrease in lower esophageal resting pressure, decrease in peristalsis wave percent, and decrease in proximal, distal body peristaltic amplitude. None significant difference regarding lower esophageal sphincter relaxation percent, residual pressure, proximal body duration, distal body duration and upper esophageal sphincter resting pressure were detected. There was significant difference regarding decrease in peristaltic wave% non transmitted wave% and proximal body amplitude in type I diabetics compared to type 2. Diabetes per se is a significant risk factor for increased incidence of esophageal motility dysfunction in the form of decreased lower esophageal resting pressure, decreased body peristalsis, increased non-transmitted wave percent. Increased double-peak wave percent decreased proximal and distal body amplitude

Prevalencia de los diferentes trastornos motores primarios del esófago: Estudio prospectivo de 5.440 casos / Primary esophageal motor disturbances among patients with esophageal symptoms

Background: The esophagus can suffer several motor disturbances of striated or smooth muscle. Aim: To determine the presence of primary motor disturbances of the esophagus among a group of patients with esophageal symptoms. Material and methods: Prospective study of 5,440 patients consulting for heartburn, chest pain or dysphagia, with primary esophageal motor disturbances, studied between 1994 and 2004. AH were subjected to an esophageal manometry with eight perfused catheters connected to pressure transducers. Results: Nineteen percent of subjects had a normal esophageal manometry, 60 percent had unspecific motor disturbances usually associated to gastroesophageal reflux, 13 percent had a nutcracker esophagus, 5 percent had diffuse esophageal spasm, 2 percent had achalasia and 0,3 percent had an hypertensive sphincter. Conclusions: Primaryesophageal motor disturbances are common among patients with esophageal symptoms. A manometry should be performed to these patients.
