Esophageal manometry in systemic sclerosis: findings and association with clinical manifestations

SUMMARY INTRODUCTION Systemic sclerosis (SSC) is an autoimmune disorder that affects several organs of unknown etiology, characterized by vascular damage and fibrosis of the skin and organs. Among the organs involved are the esophagus and the lung. OBJECTIVES To relate the profile of changes in esophageal electromanometry (EM), the profile of skin involvement, interstitial pneumopathy (ILD), and esophageal symptoms in SSC patients. METHODS This is an observational, cross-sectional study carried out at the SSC outpatient clinic of the Hospital de Clínicas of the Federal University of Uberlândia. After approval by the Ethics Committee and signed the terms of consent, 50 patients were initially enrolled, from 04/12/2014 to 06/25/2015. They were submitted to the usual investigations according to the clinical picture. The statistical analysis was descriptive in percentage, means, and standard deviation. The Chi-square test was used to evaluate the relationship between EM, high-resolution tomography, and esophageal symptoms. RESULTS 91.9% of the patients had some manometric alterations. 37.8% had involvement of the esophageal body and lower esophageal sphincter. 37.8% had ILD. 24.3% presented the diffuse form of SSC. No association was found between manometric changes and clinical manifestations (cutaneous, pulmonary, and gastrointestinal symptoms). CONCLUSION The present study confirms that esophageal motility alterations detected by EM are frequent in SSC patients, but may not be related to cutaneous extension involvement, the presence of ILD, or the gastrointestinal complaints of patients.

RESUMO INTRODUÇÃO A esclerose sistêmica (ES) é uma doença autoimune que afeta vários órgãos de etiologia desconhecida, caracterizada por dano vascular e fibrose da pele e órgãos. Entre os órgãos envolvidos estão o esôfago e o pulmão. OBJETIVOS Relacionar o perfil das alterações na eletromanometria (ME), o perfil de acometimento da pele, a pneumopatia intersticial (PI) e os sintomas esofágicos em pacientes com ES. MÉTODO Trata-se de um estudo observacional, transversal, realizado no ambulatório de SSC do Hospital das Clínicas da Universidade Federal de Uberlândia. Após aprovação pelo Comitê de Ética e assinatura dos termos de consentimento, 50 pacientes foram inicialmente convidados, de 04/12/2014 a 25/06/2015. Eles foram submetidos às investigações usuais de acordo com o quadro clínico. A análise estatística foi descritiva em porcentagem, média e desvio padrão. O teste Qui-quadrado foi utilizado para avaliar a relação entre ME, tomografia de alta resolução e sintomas esofágicos. RESULTADOS 91,9% dos pacientes apresentaram alterações manométricas. 37,8% tinham envolvimento do corpo esofágico e do esfíncter esofágico inferior. 37,8% tinham IP. 24,3% apresentaram a forma difusa da ES. Não há associação entre alterações manométricas e manifestações clínicas (sintomas cutâneos, pulmonares e gastrointestinais). CONCLUSÃO O presente estudo confirma que as alterações da motilidade esofágica detectadas pela EM são frequentes em pacientes com SSC, mas podem não estar relacionadas ao envolvimento cutâneo, à de DPI ou às queixas gastrointestinais dos pacientes.

O papel do gradiente pressórico transdiafragmático na fisiopatologia da doença do refluxo gastroesofágico / The role of the transdiaphragmatic pressure gradient in the pathophysiology of gastroesophageal reflux disease

ABSTRACT Gastroesophageal reflux disease (GERD) is the most common disease of the upper gastrointestinal tract in the Western world. GERD pathophysiology is multifactorial. Different mechanisms may contribute to GERD including an increase in the transdiaphragmatic pressure gradient (TPG). The pathophysiology of GERD linked to TPG is not entirely understood. This review shows that TPG is an important contributor to GERD even when an intact esophagogastric barrier is present in the setting of obesity and pulmonary diseases.

RESUMO A doença do refluxo gastroesofágico (DRGE) é a enfermidade mais comum do trato digestivo alto no mundo ocidental. A fisiopatologia da DRGE é multifatorial. Diferentes mecanismos podem contribuir para um aumento do gradiente pressórico transdiafragmático (GPT). A fisiopatologia da DRGE associada ao GPT não é totalmente compreendida. Esta revisão enfoca que o GPT é um importante contribuinte para DRGE mesmo na presença de uma barreira gastroesofágica intacta como na obesidade e doenças pulmonares crônicas.

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 ...

Doença do refluxo gastroesofágico / Gastroesophageal reflux disease

A doença do refluxo gastroesofágico (DRGE) é uma afecção crônica frequente na prática médica, interferindo negativamente na qualidade de vida dos pacientes. Apresenta um amplo espectro de sintomas, classificados como típicos e atípicos, sendo a pirose a principal manifestação. O tratamento inclui medidas comportamentais farmacológicas e eventualmente cirúrgicas

Gastroesophageal reflux disease (GERD) is a common chronic condition that affects negatively the patient's quality of life. Patients with GERD can exhibit a wide variety of symptoms, both typical and atypical. Heartburn is the main clinical presentation. Treatment consists of supportive and pharmacological measures; surgery may eventually be required

Reflujo gastroesofágico en pediatría / Gastro esophageal reflux disease in pediatrics

Gastro Esophageal Reflux (GER) is the passage of gastric content to the esophagus with or without vomitus or regurgitation. GER is a physiological process that occurs in 50 percent of newborns, spontaneously resolving at 12 to 14 months of age. When this retrograde gastric content reaches the esophagus and produces uncomfortable symptoms or complications, a disease is produced, named Gastro Esophageal Reflux Disease or GERD. Reflux episodes occur due to transient relaxation of the inferior esophagic sphincter, triggered by distension of the gastric fundus. Nursing children show higher frequency of episodes of relaxation due to a higher frequency of feeding than older children do. Most frequent symptoms include frequent regurgitation, with out without vomit, weight loss or poor weight gain, irritability, pyrosis, hematemesis, dysphagia, odinophagia, sibillances, stridor, cough, dysphonia, among others. These are very inespecific symptoms. Studies for GERD include 24 H pHmeasurement, which permits the study of associatrion between one of these symptoms and reflux, as well as the study of those patients with poor response to medical treatment. Unfortunately, it does not detect non-acid reflux. Multichannel intraluminal pH impedance measurement is a relatively new exam that measures the movement of fluids, gas or solids by a change in electric impedance through the esophagus. It allows to detect small volumes, type of content, acid and non acid and correlated with symptoms of GERD. Other useful exams include endoscopy with biopsy of the esophagus for diagnosis of esophagitis, esophageal mannometry for specific cases and gastroesophagic scintigram for pulmonary aspiration. Treatment include change in lifestyle (feeding, position, habits), pharmacological treatment and surgery. Medical treatment includes antacids, PPIs, most frequently omeprazole, H2 blockers such as ranitidine have a lower rate of healing of esophagitis than omeprazole, and appears to show tachyph...

El reflujo gastroesofagico (RGE) es el paso del contenido gástrico hacia el esófago con o sin vómitos o regurgitación. El RGE es un proceso normal fisiológico que ocurre en el 50 por ciento de los lactantes, resolviéndose espontáneamente a los 12 a 14 meses de edad. Cuando este contenido retrógrado gástrico alcanza al esófago y produce síntomas molestos o complicaciones se produce la enfermedad por RGE o ERGE. Los episodios de reflujo se producen principalmente por relajaciones transitorias del esfínter esofágico inferior (LES) gatillado por distensión del fondo gástrico. Los lactantes presentan mayor numero de episodios de relajación del LES debido a que se alimentan con más frecuencia que los niños mayores. Los síntomas más frecuentes asociados con reflujo patológico son regurgitaciones frecuentes con o sin vómitos, pérdida de peso o pobre ganancia de peso, irritabilidad, pirosis, hematemesis, disfagia, odinofagia, sibilancias, estridor, tos, disfonía entre otros, estos síntomas son poco específicos en lactantes y niños menores. Los exámenes para el estudio de ERGE son la pH metría de 24 hrs que permite estudiar la asociación entre un síntoma y el reflujo, también es útil para estudiar aquellos pacientes con mala respuesta al tratamiento médico, sin embargo, tiene el inconveniente que no detecta episodios de reflujo no ácidos. La pH-Impedanciometria Intraluminal multicanal (pH IIM) es un examen relativamente nuevo mide los movimientos de fluidos, gas o sólidos a través de cambios en la impe-dancia eléctrica a lo largo del esófago; permite distinguir pequeños volúmenes refluidos y el tipo de contenido, detecta reflujo acido y no acido y correlaciona síntomas con ERGE. Otros exámenes útiles son la endoscopia con biopsia de esófago para estudio de esofagitis. La Manometría esofágica tiene sus indicaciones específicas y la Cintigrafía gastroesofágica que es otro examen que se utiliza principalmente para estudiar aspiración pulmonar. El tratamiento incluye cambi...

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.

Correlation between Clinical Symptoms and Radiologic Findings before and after Pneumatic Balloon Dilatation for Achalasia / 대한소화기학회지

BACKGROUND/AIMS: We investigated the risk factors for short-term recurrence and analyzed the correlation between subjective clinical symtoms and objective radiological findings in patients with achalasia undergoing pneumatic balloon dilatation. METHODS: Twenty patients who were treated by pneumatic balloon dilatation were enrolled. We compared prospectively various indices before and after the treatment as follows: 1) Eckardt symptom score and dysphagia grade, 2) The ratio of the maximal width in mid-esophageal lumen to the minimal width in distal esophagus around lower esophageal sphincter, and 3) the percentage of maximum activity retained in the esophagus at 30 seconds and T in esophageal scan two days after the treatment. RESULTS: 1) Clinical indices and radiologic indices significantly improved after pneumatic dilatation. 2) There was no significant correlation between the clinical indices and the radiologic indices before and after the treatment. 3) The difference percentage of clinical indices did not show significant correlation with the difference percentage of the radiologic indices. 4) Compared to the group above 20% in the difference percentage of 30 second residual fraction, the one below 20% had a four-fold risk in short-term recurrence. CONCLUSIONS: Clinical symptoms and radiologic indices significantly improve after pneumatic dilatation but have no significant correlation to each other. The group below 20% in the difference percentage of 30 second residual fraction has a high risk of recurrence and may need careful examination and early repeated pneumatic dilation.

Resultados inmediatos y tardíos de la miotomía de Heller laparoscópica en pacientes con acalasia esofágica / Laparoscopic Heller myotomy for esophageal achalasia

Background: Achalasia is characterized by an incomplete relaxation of the lower esophageal sphincter. The best treatment is surgical and the laparoscopic approach may have good results. Aim: To assess the results of laparoscopic Heller myotomy among patients with achalasia. Material and methods: Prospective study of patients subjected to a laparoscopic Heller myotomy between 1995 and 2004. Clinical features, early and late operative results were assessed. Results: Twenty seven patients aged 12 to 74 years (12 females) were operated. All had disphagia lasting for a mean of 32 months. Mean lower esophageal sphincter pressure ranged from 18 to 85 mmHg. Eight patients received other treatments prior to surgery but symptoms persisted or reappeared. The preoperative clinical score was 7. No patient died and no procedure had to be converted to open surgery. In a follow up of 21 to 131 months, all patients are satisfied with the surgical results and the postoperative clinical score is 1. Only one patient with a mega esophagus maintained a clinical score of six. Conclusions: In this series of patients, laparoscopic Heller myotomy was an effective and safe treatment for esophageal achalasia.

Esophageal motility disorders in diabetics with and without neuropathy

To detect the presence of esophageal motor disorders in diabetic patients, and to establish whether there is any difference between patients with and without neuropathy. Fifty-six diabetic patients admitted at Department of Medicine at Ziauddin Medical University Hospital, Karachi were selected to observe if manometeric findings were different in diabetic patients with and without diabetic neuropathy. Poor glycemic control was observed amongst patients with diabetic neuropathy as compared to those without neuropathy. Double peaked peristalsis and failure of peristalsis was more common in patients with diabetic neuropathy as compared to those without neuropathy. High amplitude and broader wave peristalsis and hypertensive lower esophageal sphincter was found in patients without neuropathy. Aperistalsis and multiple peaked waves were equally prevalent in patients with and without neuropathy. Poor glycemic control was found in patients with diabetic neuropathy, double peaked and failed peristalsis was the most common manometric abnormality among them
