ABSTRACT

Objetivos: classificar pacientes chagásicos com a forma digestiva da doença associando com variáveis demográficas, clínicas e de utilização de serviços de saúde, além de analisar as possibilidades de atuação da Atenção Primária à Saúde (APS) no manejo e acompanhamento dos casos. Casuística e métodos: estudo transversal com base em dados secundários provenientes de prontuários. Foram utilizadas as classificações do megaesôfago e do megacólon propostas por Rezende (1982) e Silva (2013), respectivamente. Resultados: Foram analisados 156 prontuários, sendo 94 (60,2%) relativos a megaesôfagos, 29 (18,6%) a megacólons e 29 (18,6%) a ambas as formas clínicas. O maior número de internações (p=0,02; OR=3,71) e de dias internados (p<0,01; OR=3,30) foi associado aos pacientes classificados nos grupos III e IV de megaesôfago. Em relação ao sexo masculino (p=0,02), o maior número de internações (p<0,0001) e de dias internados (p<0,0001) foi associado aos pacientes classificados no grau III de megacólon. Conclusões: Concluiu-se que a APS possui papel importante na diminuição da sobrecarga dos serviços de média e alta complexidade com o acompanhamento dos casos estáveis e menos graves e que a melhoria da qualidade de vida dos pacientes chagásicos é um efeito direto que pode ser esperado do protagonismo da APS neste cuidado.


Objectives: To classify chagasic patients with the digestive form of the disease, associating with demographic, clinical, and use of health services variables, in addition to analyzing the possibilities of Primary Health Care (PHC) acting in the management and follow-up of cases. Casuistry and Methods: A cross-sectional study based on secondary data from medical records was conducted. We used the classification of megaesophagus and megacolon proposed by Rezende (1982) and Silva (2013), respectively. Results: 156 medical records were analyzed: 94 (60.2%) related to megaesophagus, 29 (18.6%) to megacolon, and 29 (18.6%) with both clinical forms. The highest number of hospitalizations (p=0.02; OR=3.71) and days hospitalized (p<0.01; OR=3.30) were associated with patients classified in groups III and IV with megaesophagus. Male gender (p=0.02), more hospitalizations (p=0.0001), and more days in the hospital (p=0.0001) were all linked to patients classified as having gradeIII megacolon. Conclusions: We concluded that PHC has an important role in reducing the burden of medium and high-complexity services with the monitoring of stable and less severe cases. It also demonstrated the direct effect of PHC protagonism on the improvement of chagasic patients' quality of life.

ABSTRACT

Pseudoacalasia se manifesta de forma semelhante à acalasia do esfíncter esofágico inferior (EEI). Corresponde a 2,4 a 4% dos casos que simulam acalasia 1 . Estima-se que cerca de 50% dos casos de pseudoacalasia correspondam a malignidade primária do esôfago e da junção gastroesofágica e 18% a malignidades secundárias como doença metastática 1,2 . Etiologias benignas também estão descritas. No presente trabalho apresentamos um caso de pseudoacalasia com ênfase nos aspectos radiológicos. Revisamos também aspectos clínicos e radiológicos que podem auxiliar no diagnóstico diferencial entre acalasia e pseudoacalasia. (AU)


Pseudoachalasia is a condition that mimics idiopathic achalasia of the lower esophageal sphincter. It accounts for 2.4 to 4% of patients presenting with achalasia-like symptoms. It is estimated that about 50% of cases of pseudoachalasia correspond to primary malignancies of the esophagus and the esophagogastric junction and 18% to secondary malignancies such as metastases 1,2 . Benign causes are also described. In this report we emphasize radiological findings of a case of pseudoachalasia. We also review clinical and radiological aspects that might be auxiliary in the differential diagnosis between achalasia and pseudoachalasia. (AU)

ABSTRACT

Resumen El megaesófago se presenta entre el 5 % y el 20 % de pacientes con acalasia, un trastorno motor esofágico primario reconocido hace más de 300 años, a considerarse en todo paciente con disfagia no explicada por un proceso obstructivo o inflamatorio luego de un estudio endoscópico detallado. Se presenta el caso de un paciente con disfagia progresiva, en quien se documentó megaesófago como complicación de una acalasia de largo tiempo de evolución, no tratada. Se descartó la enfermedad de Chagas mediante enzimoinmunoensayo (ELISA) e inmunofluorescencia indirecta (IFI), tal como recomiendan las guías actuales. Ante la baja frecuencia de esta entidad en nuestro medio y las implicaciones terapéuticas que tiene para los pacientes con acalasia, se realizó una revisión narrativa en la literatura sobre su diagnóstico y alternativas de manejo.


Abstract Megaesophagus occurs in between 5% and 20% of patients with achalasia. It is a primary esophageal motor disorder that has been known for more than 300 years. It should be considered in all patients with dysphagia that is not explained by an obstructive or inflammatory process after a detailed endoscopic study. The following is the case of a patient with progressive dysphagia, in whom megaesophagus was documented as a complication of untreated, long-standing achalasia. Chagas disease was ruled out by enzyme immunoassay (ELISA) and indirect immunofluorescence (IF), as recommended by current guidelines. Given the low frequency of this entity in our environment and the therapeutic implications for patients with achalasia, a narrative literature review was carried out to describe its diagnosis and treatment alternatives.

ABSTRACT

The brachiocephalic trunk and the left subclavian artery originate from the aortic arch, and both supply blood to the head, neck, and thoracic limbs. Anatomical variations, such as an aberrant right subclavian artery, are congenital conditions rarely observed in dogs, Thus, the objective of the present report was to describe a case of aberrant right subclavian artery in a 9-year-old Dalmatian. However, this anomaly was a finding in which the patient was asymptomatic during its 9 years of life and only at this age did he exhibit signs including sialorrhea, vomiting, hyporexia, and noisy deglutition. Blood count, biochemical profile, and thoracic radiography led to a diagnosis of megaesophagus and aspiration pneumonia. Despite the recommended treatment, the patient did not respond well; as such, the owner elected to euthanize the animal. On necropsy, the right subclavian artery originated directly from the aortic arch, followed a route from left to right dorsally to the esophagus, and then formed an impression of the vascular path over the muscular wall of the esophagus. The esophagus, in turn, exhibited a flaccid wall and dilation in the caudal portion to the vascular path made by the ectopic position of the right subclavian artery.(AU)


O tronco braquiocefálico e a artéria subclávia esquerda emergem do arco aórtico e são responsáveis por fazerem o suprimento sanguíneo para cabeça, pescoço e membros torácicos. Variações anatômicas, como a ectopia da artéria subclávia direita, são alterações congênitas raramente encontradas em cães, cujas alterações do sistema digestivo acontecem em pacientes recém-desmamados e não em adultos. Assim, o objetivo deste relato é descrever um caso de ectopia da artéria subclávia direita em uma cadela, Dálmata, de nove anos de idade. No entanto, essa anomalia foi um achado do qual o paciente foi assintomático durante os nove anos de vida e somente com essa idade apresentou sinais como sialorreia, vômito, hiporexia e deglutição ruidosa. O hemograma e os perfis bioquímicos, associados à radiografia torácica, levaram a um diagnóstico de megaesôfago e pneumonia aspirativa. Mesmo seguindo o tratamento recomendado, houve piora clínica do quadro e o animal foi submetido à eutanásia. À macroscopia, a artéria subclávia direita originava-se direto do arco aórtico, fazia um percurso da esquerda para a direita dorsalmente ao esôfago e, então, formava uma impressão do trajeto vascular sobre a parede muscular do esôfago. O esôfago, por sua vez, apresentava parede flácida e dilatação na porção caudal ao trajeto vascular feito pela posição ectópica da artéria subclávia direita.(AU)

ABSTRACT

ABSTRACT BACKGROUND: Achalasia is a neurodegenerative motility esophageal disorder characterized by failure of lower esophageal sphincter relaxation. The conventional treatment option for achalasia has been laparoscopic Heller myotomy (LHM). However, in 2010, Inoue et al. described peroral endoscopic myotomy (POEM), a minimally invasive procedure, as an alternative therapy. To date, some studies with small sample sizes have aimed to compare outcomes of LHM vs POEM. OBJECTIVE: Thus, the aim of this study is to perform a systematic review and meta-analysis to better evaluate the efficacy and safety of these two techniques. METHODS: Individualized search strategies were developed from inception through April 2019 in accordance with PRISMA guidelines. Variables analyzed included operative time, overall adverse events rate, post-procedure gastroesophageal reflux disease (GERD), hospitalization length, post-procedure pain score, and Eckardt Score reduction. RESULTS: Twelve cohort trials were selected, consisting of 893 patients (359 in POEM group and 534 in LHM.) No randomized clinical trials were available. There was no difference in operative time (MD= -10,26, 95% CI (-5,6 to 8,2), P<0.001) or Post-Operative Gastroesophageal Reflux (RD: -0.00, 95%CI: (-0.09, 0.09), I2: 0%). There was decreased length of hospital stay for POEM (MD: -0.6, 95% CI (-1.11, -0.09), P=0.02), and an increased mean reduction in Eckardt score in POEM patients (MD = -0.257, 95% CI: (-0.512 to -0.002), P=0.048), with similar rates of adverse events. CONCLUSION: POEM demonstrated similar results compared to laparoscopic Heller myotomy with regards to improvement of dysphagia, post-procedure reflux, and surgical time, with the benefit of shorter length of hospital stay. Therefore, POEM can be considered an option for patients with achalasia.


RESUMO CONTEXTO: A acalasia é um distúrbio esofágico da motilidade neurodegenerativa caracterizado por falha no relaxamento do esfíncter esofágico inferior (EEI). A opção de tratamento convencional para acalasia tem sido a miotomia laparoscópica de Heller (LHM). No entanto, em 2010, Inoue et al. descreveram a miotomia endoscópica peroral (POEM), um procedimento minimamente invasivo, como uma terapia alternativa. Até o momento, poucos estudos com amostras pequenas tiveram como objetivo comparar os resultados do LHM versus POEM. OBJETIVO: Assim, o objetivo deste estudo é realizar uma revisão sistemática e metanálise para melhor avaliar a eficácia e segurança dessas duas técnicas. MÉTODOS: Estratégias de busca individualizadas foram desenvolvidas desde o início até abril de 2019, de acordo com as diretrizes do PRISMA. As variáveis analisadas incluíram tempo operatório, taxa global de eventos adversos, doença de refluxo gastroesofágico (DRGE) pós-procedimento, tempo de internação, escore de dor pós-procedimento e redução do escore de Eckardt. RESULTADOS: Doze estudos de coorte foram selecionados, consistindo em 893 pacientes (359 no grupo POEM e 524 no LHM). Nenhum ensaio clínico randomizado estava disponível. Não houve diferença no tempo operatório (MD = -10,26, IC 95% (-5,6 a 8,2), P<0,001) ou refluxo gastroesofágico pós-operatório (RD: -0,00, 95% IC: (-0,09, 0,09), I2: 0%). Houve diminuição do tempo de permanência hospitalar para POEM (MD: -0,6, 95% CI (-1,11, -0,09), P=0,02) e um aumento da redução média no escore de Eckardt em pacientes POEM (MD= -0,257, IC95%: (-0,512 a -0,002), P=0,048), com taxas similares de eventos adversos. CONCLUSÃO: O POEM demonstrou resultados semelhantes aos da miotomia a Heller por videolaparoscopia, com melhora da disfagia, do refluxo pós-procedimento e tempo cirúrgico, com o benefício de menor tempo de internação hospitalar. Portanto, o POEM pode ser considerado uma opção para pacientes com acalasia.

ABSTRACT

ABSTRACT Objective: to analyze the surgical treatment of patients with recurrent megaesophagus followed at the esophageal-stomach-duodenal outpatient clinic of the Hospital de Clínicas - UNICAMP. Methods: a retrospective study, from 2011 to 2017, with 26 patients with Chagas or idiopathic megaesophagus, surgically treated, and who recurred with dysphagia. Clinical, endoscopic and radiographic aspects were assessed and correlated with the performed surgical procedures. Results: 50% had dysphagia for liquids, 69% regurgitation, 65.3% heartburn, 69.2% weight loss and 69.2% had Chagas disease. In addition, 38.4% had megaesophagus stage 1 and 2 and 61.5% stage 3 and 4. Regarding the reoperations, 53% of them underwent Heller-Pinotti surgery by laparoscopy, Serra-Dória in 30.7% and esophageal mucosectomy in 7.9%. In 72% of the reoperations there were no postoperative complications, and 80% of the patients had a good outcome, with reduction or elimination of dysphagia. Among the reoperated patients undergoing the laparoscopic Heller-Pinotti technique, three reported little improvement of dysphagia in the postoperative period and among those who underwent Serra-Dória surgery, 100% had no dysphagia. It was observed that, when the time between the first procedure and the reoperation was longer, the better the surgical result was, with statistical significant decreased dysphagia (p=0.0013, p<0.05). Conclusions: there was a preference to perform laparoscopic re-miotomy and, as a second option, Serra-Dória surgery, for patients with recurrent megaesophagus. Esophagectomy or esophageal mucosectomy were reserved for more severe patients.


RESUMO Objetivo: analisar o tratamento cirúrgico dos pacientes com megaesôfago recidivado acompanhados no ambulatório de cirurgia de esôfago-estômago-duodeno do Hospital de Clínicas da UNICAMP. Métodos: estudo restrospectivo no período de 2011 a 2017, com 26 pacientes portadores de megaesôfago chagásico ou idiopático, tratados cirurgicamente e que evoluíram com recidiva da disfagia. Foram avaliados aspectos clínicos, endoscópicos e radiográficos, sendo correlacionados com os procedimentos cirúrgicos realizados. Resultados: 50% apresentava disfagia para líquidos, 69% regurgitação, 65,3% pirose, 69,2% perda de peso e 69,2% era chagásico. Além disso, 38,4% apresentavam megaesôfago estágio 1 e 2 e 61,5% estágio 3 e 4. Quanto às reoperações, em 53% foi realizada a cirurgia de Heller-Pinotti videolaparoscópica, seguida de Serra-Dória em 30,7% e mucosectomia esofágica em 7,9%. Em 72% das reoperações não houve complicações pós-operatórias e 80% tiveram evolução satisfatória com redução ou ausência da disfagia. Dentre os pacientes reoperados pela técnica de Heller-Pinotti videolaparoscópica, três referiram pouca melhora da disfagia no pós-operatório. Dentre os pacientes submetidos à cirurgia de Serra-Dória, 100% tiveram evolução satisfatória da disfagia. Foi observado nos pacientes com o tempo entre a primeira cirurgia e a reoperação mais longo, um melhor resultado cirúrgico com diminuição da disfagia, com relevância estatística (p=0,0013, p<0,05). Conclusão: houve preferência nas reoperações de megaesôfago pela realização de re-miotomia por videolaparoscopia e, como segunda opção, a cirurgia de Serra-Dória. A esofagectomia ou mucosectomia esofágica foram reservadas para os casos mais avançados.

ABSTRACT

ABSTRACT Background: High-resolution manometry is more costly but clinically superior to conventional manometry. Water-perfused systems may decrease costs, but it is unclear if they are as reliable as solid-state systems, and reference values are interchangeable. Aim: To validate normal values for a new water-perfusion high-resolution manometry system. Methods: Normative values for a 24-sensors water perfused high-resolution manometry system were validated by studying 225 individuals who underwent high resolution manometry for clinical complaints. Patients were divided in four groups: group 1 - gastroesophageal reflux disease; group 2 - achalasia; group 3 - systemic diseases with possible esophageal manifestation; and group 4 - dysphagia. Results: In group 1, a hypotonic lower esophageal sphincter was found in 49% of individuals with positive 24 h pH monitoring, and in 28% in pH-negative individuals. In groups 2 and 3, aperistalsis was found in all individuals. In group 4, only one patient (14%) had normal high-resolution manometry. Conclusions: The normal values determined for this low-cost water-perfused HRM system with unique peristaltic pump and helicoidal sensor distribution are discriminatory of most abnormalities of esophageal motility seen in clinical practice.


RESUMO Racional: A manometria de alta resolução é mais custosa, porém clinicamente superior à manometria convencional. Sistemas por perfusão de água podem ter custo diminuído, mas não é certo se são tão eficazes quanto aos sistemas de estado sólido e se os valores de referência são intercambiáveis. Objetivo: Este estudo visa validar valores de normalidade para um novo sistema por perfusão de água. Método: Valores de normalidade para um sistema de manometria de alta resolução de 24 sensores por perfusão de água foram validados estudando 225 indivíduos submetidos à manometria de alta resolução por queixas clínicas. Pacientes foram divididos em quatro grupos: grupo 1 - doença do refluxo gastroesofágico; grupo 2 - acalasia; grupo 3 - doenças sistêmicas com possível doenças sistêmicas com comprometimento esofágico; e grupo 4 - pacientes com disfagia. Resultado: No grupo 1, esfíncter esofagiano inferior hipotônico foi encontrado em 49% dos indivíduos com pHmetria positiva e 28% daqueles com pHmetria negativa. Nos grupos 2 e 3, aperistalse foi encontrada em todos indivíduos. No grupo 4, somente um paciente (14%) tinha manometria normal. Conclusão: Os valores de normalidade definidos para este sistema de manometria de alta resolução por perfusão de água são discriminatórios da maioria das anormalidades da motilidade esofágica vistas na prática clínica.

ABSTRACT

O megaesôfago chagásico é uma alteração do trato gastrointestinal caracterizada pela destruição ou ausência de plexos nervosos intramurais do esôfago. Alterações nutricionais e da saúde pulmonar são descritas como consequentes a esse diagnóstico. Objetivo: descrever os achados das fases oral e faríngea da deglutição em indivíduos portadores de Megaesôfago Chagásico Metodologia: participaram desta pesquisa 26 voluntários com diagnóstico confirmado de doença de Chagas. Todos realizaram avaliação videofluoroscópica da deglutição, ao deglutir sólido, líquido, semilíquido e pastoso. Resultados: observou-se prevalência do sexo feminino (73,1%), e os graus I e II de classificação do megaesôfago foram os mais encontrados. A ausência de unidades dentárias posteriores esteve presente em mais de 90% na população e o tipo de mastigação anterior foi observado em 40,7% da amostra. Durante o exame videofluoroscópico , a presença de resíduo oral, faríngeo e em região de transição faringoesofágica foi mais encontrado na consistência semilíquida, além de um tempo de trânsito oral total aumentado para o sólido. Conclusão: escape posterior, resíduos orais, faríngeos e na transição faringoesofágica na consistência semi-líquida foram os achados mais encontrados no grupo estudado.


Chagasic Megaesophagus is an alteration of the gastrointestinal tract, characterized by the destruction or absence of intramural nerve plexuses of the esophagus. Nutritional and pulmonary health changes are described as a consequence of this diagnosis. Objective: to describe the findings of the oral and pharyngeal stages of swallowing in individuals with Chagasic Megaesophagus. Methodology: twenty ­ six volunteers with confirmed diagnosis of Chagas' disease participated in this research. All performed videofluoroscopic swallowing evaluation when swallowing solid, liquid, semi-liquid and pasty food. Results: there was a prevalence of females (73.1%), and megaesophagus grades I and II were found most often. The absence of posterior dental units was present in more than 90% in the population and the anterior chewing type was observed in 40.7% of the sample. During videofluoroscopic examination, the presence of oral, pharyngeal and pharyngoesophageal transition region residues was found more in semi-liquid consistency in addition to having an increased total oral transit time for the solid ones. Conclusion: the presence of posterior escape, oral, pharyngeal and pharyngoesophageal transition residues in semi-liquid consistency was found.

ABSTRACT

Antecedentes: desde la introducción de la funduplicatura laparoscópica en 1991 para tratar la enfermedad por reflujo gastroesofágico, se han desarrollado diferentes procedimientos mininvasivos hasta llegar en la actualidad a las esofagectomías totalmente toracoscópicas y laparoscópicas. Objetivo: analizar los eventos adversos durante la esofagectomía mininvasiva en posición prona durante la curva de aprendizaje. Material y métodos: en el período comprendido entre noviembre de 2011 y junio de 2017 fueron intervenidos quirúrgicamente en el Hospital Interzonal General de Agudos San Martín (HIGA) y el Instituto de Diagnóstico de La Plata 36 pacientes mediante esofagectomía mininvasiva (EMI) en posición prona (PP). Resultados: durante el tiempo abdominal se produjo una lesión de vasos coronarios. En el tiempo torácico se registraron dos lesiones pulmonares, una lesión del cayado de vena ácigos y una sección del conducto torácico; además hubo un caso de daño al nervio recurrente y una lesión del bronquio fuente izquierdo durante la linfadenectomía. Al analizar el total de las complicaciones se observó que la mayoría de ellas se presentaron en los primeros 20 casos, mientras que en los 16 siguientes solo se registró una lesión pulmonar (p=0,10). Conclusión: como conclusión podemos decir que la EMI en PP, como ya es sabido, es un procedimiento factible y seguro pero ‒dada su complejidad‒ puede provocar lesiones intraoperatorias graves. Aunque los resultados de nuestra serie no arrojaron diferencias de significancia estadística, la cantidad de eventos adversos durante las operaciones realizadas por el mismo equipo disminuyó sensiblemente en la medida en que se adquirió el entrenamiento suficiente.


Background: Since the initial description of laparoscopic fundoplication in 1991 for the treatment of gastroesophageal reflux disease, different minimally invasive procedures have been developed until nowadays, when esophagectomy is performed using combined thoracoscopy and laparoscopy. Objective: The aim of our study is to analyze the adverse events of minimally invasive esophagectomy in prone position during the learning curve. Material and methods: Between November 2011 and June 2017, 36 patients underwent minimally invasive esophagectomy in prone position in the Hospital Interzonal General de Agudos (HIGA) San Martín and the Instituto de Diagnóstico de La Plata. Results: During the abdominal stage one patient presented coronary vessel injury. The complications occurring in the thoracic stage included lung injury (n =2), azygos arch injury (n = 1), thoracic duct dissection (n = 1), laryngeal recurrent nerve lesion (n = 1) and main stem bronchus injury (n = 1) during lymph node resection. Most of these complications occurred in the first 20 patients, while in the remaining 16 cases only lung injury occurred (p = 0.10) Conclusion: Minimally invasive esophagectomy in prone position is a feasible and safe procedure that can cause serious intraoperative complications due to its complexity. Although the results of our series did not show statistically significant differences, the number of adverse events during surgeries performed by the same team showed an important reduction associated with better training.

Análisis estadístico: Porcentajes para variables cualitativas, media ± desviación estándar o mediana y rango según corresponda para las cuantitativas, para la comparación de los resultados del cuestionario se emplearon pruebas de hipótesis de comparación de medias, con nivel de significación estadística α= 0,05. Resultados: Fueron incluidos en el estudio 101 pacientes. Las edades oscilaban entre 18 y 78 años con una media de 47 años. El tiempo medio de evolución de los síntomas fue de 62 meses, con una media de 3,3 en la escala de disfagia y una presión de reposo del esfínter esofágico inferior (mmHg) 38,7 ± 16,8, se obtuvo un GIQLI inicial de 85,3 ± 20,4 que aumentó al año a 131,6 ± 10,5 Conclusiones: La miotomía de Heller con fundoplicatura de Dor, mejora la calidad de vida de los pacientes con acalasia esofágica con una evolución clínica excelente(AU)


ABSTRACT Introduction: Laparoscopic Heller myotomy is now considered the treatment of choice for the relief of dysphagia. It has been shown that thanks to it a low incidence of gastroesophageal reflux and evident improvement in the quality of life is achieved. Objective: To evaluate the quality of life and clinical evolution of patients after Heller myotomy plus Dor fundoplication. Method: Prospective, longitudinal, descriptive, observational study carried out by applying the Gastrointestinal Quality of Life Index (GIQLI) questionnaire to patients operated on for esophageal achalasia, from January 2010 to December 2017, at the National Center for Minimum Access Surgery. The questionnaire was applied preoperatively and one year after surgery. Statistical analysis: Percentages for qualitative variables, mean and standard deviation, or median and range, as appropriate for quantitative variables. For the comparison of the results of the questionnaire, we used tests of hypothesis of comparison of means, with statistical significance level of 0.05. Results: The ages ranged between 18 and 78 years, with an average of 47 years. The mean time of evolution of symptoms was 62 months, with an average of 3.3 on the dysphagia scale and a resting pressure of the lower esophageal sphincter (mmHg) 38.7±16.8. An initial gastrointestinal quality of life index of 85.3±20.4 was obtained, which increased to 131.6±10.5 per year. Conclusions: Heller myotomy plus Dor fundoplication improves the quality of life of patients with esophageal achalasia and guarantees an excellent clinical evolution(AU)

INTRODUCCIÓN: La acalasia es el trastorno motor primario más frecuente del esófago. Su incidencia reportada es baja, aún más en pacientes pediátricos. La miotomía de Heller laparoscópica corresponde al estándar actual de tratamiento. Durante los últimos años la miotomía endoscópica por vía oral (POEM) se ha posicionado como una alternativa terapéutica segura y tan efectiva como el Heller para la acalasia esofágica. OBJETIVO: Describir la técnica de POEM y reportar el primer caso pediátrico en nuestro país. CASO CLÍNICO: Paciente de 11 años, previamente sano, que se presentó con disfagia ilógica progresiva y baja de peso. El estudio concluyó una acalasia tipo II. Fue sometido a POEM y cursó un postoperatorio sin incidentes. A un año de la intervención se ha documentado resolución de la sintomatología, seguimiento endoscópico y manométrico sin complicaciones. CONCLUSIONES: El caso descrito corresponde al primer POEM en un paciente pediátrico en nuestro país. La acalasia esofágica es infrecuente en pediatría y el POEM ha demostrado éxito clínico y seguridad comparables a la miotomía de Heller laparoscópica en el corto y mediano plazo. El seguimiento a largo plazo permitirá determinar su rol definitivo en el tratamiento de pacientes pediátricos con acalasia esofágica.


INTRODUCTION: Achalasia is the most common primary motor disorder of the esophagus. Its reported incidence is low, even more in pediatric patients. Laparoscopic Heller myotomy is the current stan dard of treatment. During the last years, per-oral endoscopic myotomy (POEM) has been positioned as a safe and effective therapeutic alternative as the Heller procedure for esophageal achalasia. OBJECTIVE: To describe the POEM technique and report the first pediatric case in our country. CLINICAL CASE: 11-year-old patient, previously healthy, who presented with progressive dysphagia for solids and liquids and weight loss. The study concluded a type II achalasia. The patient underwent a POEM and had a postoperative course without incidents. One year after the intervention, symptomatic, endoscopic and manometric resolution have been documented. CONCLUSIONS: The described case is the first POEM in a pediatric patient in our country. Esophageal achalasia is uncommon in pediatrics and POEM has demonstrated clinical success and safety comparable to laparoscopic Heller myotomy in short and medium term. Long-term follow-up will determine its definitive role in the treatment of pediatric patients with esophageal achalasia.

ABSTRACT

La palabra 'acalasia' es un neologismo de origen griego, acuñado por el médico inglés Sir Edwin Cooper en 1913, y significa: sin calidad de relajación. La acalasia es una enfermedad que se manifiesta clínicamente por disfagia para sólidos y para líquidos, regurgitación esofágica, dolor retroesternal, tos, broncoaspiración, neumonía, acidez estomacal y pérdida de peso. Su fisiopatología corresponde a la ausencia de peristalsis esofágica e insuficiente relajación del esfínter esofágico inferior. Estas anormalidades motoras se deben a la pérdida de las neuronas mientéricas que coordinan la peristalsis esofágica y la relajación del esfínter esofágico inferior. Fue descrita por primera vez por Sir Thomas Willis en 1674. Aunque actualmente se considera idiopática, se han comenzado a considerar como posibles causas las alteraciones autoinmunitarias y la predisposición genética; además, las infecciones por virus herpes y por virus herpes zóster se han implicado como causas probables. Su incidencia anual oscila entre 0,3 y 1,63 por 100.000 personas en adultos, con una prevalencia anual de 10 en 100.000 habitantes. Afecta por igual a los dos sexos, y el grupo etario más afectado es el de 30 a 60 años. El diagnóstico se sospecha por los síntomas que presenta el paciente, de los cuales la disfagia es el más importante. Se confirma por medio de la endoscopia de las vías digestivas altas, el esofagograma y la manometría de alta resolución. El tratamiento sigue siendo paliativo y se puede orientar por el subtipo de acalasia, según la clasificación de Chicago. Los mejores resultados se obtienen mediante las técnicas de dilatación neumática, miotomía laparoscópica de Heller y, más recientemente, mediante la miotomía endoscópica peroral (Per-Oral Endoscopic Myotomy, POEM), descrita por Haruhiro Inoue en Japón en el año 2008. Aún faltan estudios prospectivos aleatorizados con seguimiento a largo plazo para determinar cuál es la mejor técnica. Se presenta una revisión actualizada del tema


The word achalasia is a neologism of Greek origin, coined by the English physician Sir Edwin Cooper in 1913, and means no quality of relaxation. Achalasia is a disease clinically manifested by dysphagia with both solids and liquids, esophageal regurgitation, retrosternal pain, cough, bronchial aspiration, pneumonia, heartburn and weight loss. Physiopathologically it corresponds to the loss of esophageal peristalsis and to an insufficient relaxation of the lower esophageal sphincter (LES). These motor abnormalities are due to the loss of myenteric neurons that coordinate esophageal peristalsis and relaxation of the LES. First described by Sir Thomas Willis in 1674, and although it is currently considered idiopathic, it has begun to be considered as possible causes autoimmune components and genetic predisposition; viral infections by herpes and chickenpox zoster have also been implicated as probable causes. Its incidence ranges from 0.3 to 1.63 per 100,000 adults, with a prevalence of 10 in 100,000 inhabitants per year. It affects equally any gender, and the age group between 30 and 60 years is the most affected. The diagnosis is suspected based on the symptomatology, with dysphagia being the most important symptom. It is confirmed with the performance of endoscopy of the upper digestive tract, esophagogram and high resolution manometry. The treatment remains palliative, and may be guided by the subtype of achalasia, according to the Chicago classification. The best results are obtained by the techniques of pneumatic dilation, Heller's laparoscopic myotomy, and more recently by the POEM technique (per oral endoscopic myotomy), described in 2008 in Japan by Haruhiro Inoue. There is still a lack of prospective randomized studies with long-term follow-up that determine which is the best technique. An updated review of the subject is presented

ABSTRACT

ABSTRACT Background: Among the anastomoses of the gastrointestinal tract, those of the esophagus are of special interest due to several anatomical or even general peculiarities. Aim: Evaluate retrospectively the results comparing mechanical vs. manual suture at cervical esophagogastric anastomosis in megaesophagus treatment. Methods: Were included 92 patients diagnosed with advanced megaesophagus with clinical conditions to undergo the surgery. All underwent esophageal mucosectomy, performing anastomosis of the esophagus stump with the gastric tube at the cervical level. In order to make this anastomosis, the patients were divided into two groups: group A (n=53) with circular mechanical suture, lateral end; group B (n=39) with manual suture in two sides, lateral end. In the postoperative period, an early evaluation was performed, analyzing local and systemic complications and late (average 5.6 y) analyzing deglutition. Results: Early evaluation: a) dehiscence of esophagogastric anastomosis n=5 (9.4%) in group A vs. n=9 (23.0%) in group B (p=0.0418); b) stenosis of esophagogastric anastomosis n=8 (15.1%) in group A vs. n=15 (38.4%) in group B (p=0.0105.); c) pulmonary infection n=5 (9.4%) in group A vs. n=3 (7.6%) in group B (p=1.0000.); d) pleural effusion n=5 (9.4%) in group A vs. n=6 (15.4%) in group B (p<0.518). Late evaluation showed that 86.4-96% of the patients presented the criteria 4 and 5 from SAEED, expressing effective swallowing mechanisms without showing significant differences among the groups. Conclusion: Cervical esophagogastric anastomosis by means of mechanical suture is more proper than the manual with lower incidence of local complications and, in the long-term evaluation, regular deglutition was acquired in both suture techniques in equal quality.


RESUMO Racional: Das anastomoses do trato gastrointestinal, as do esôfago têm especial interesse devido às varias peculiaridades anatômicas e mesmo sistêmicas. Objetivo: Avaliar retrospectivamente os resultados comparando a sutura mecânica e manual na anastomose esofagogástrica cervical no tratamento do megaesôfago. Métodos: Foram estudados 92 pacientes com diagnóstico de megaesôfago avançado com condições clínicas de serem submetidos à operação. Todos foram submetidos à mucosectomia esofágica, sendo realizada anastomose do coto esofágico com o tubo gástrico no nível cervical. Para a realização desta anastomose, foram divididos em dois grupos: grupo A (n=53) com sutura mecânica circular terminolateral; grupo B (n=39) com sutura manual em dois planos terminolateral. No período pós-operatório foi realizada avaliação precoce, com análise das complicações locais e sistêmicas, e tardia (média 5,6 anos) com análise da deglutição. Resultados: Avaliação precoce: a) deiscência da anastomose esofagogástrica, n=5 (9,4%) no grupo A vs. n=9 (23,0%) no grupo B (p=0.0418); b) estenose da anastomose esofagogástrica n=8 (15,1%) no grupo A vs. n=15 (38,4%) no grupo B (p=0.0105); c) infecção pulmonar n=5 (9,4%) no grupo A vs. n=3 (7,6%) no grupo B (p=1.000); d) derrame pleural n=5 (9,4%) no grupo A vs. n=6 (15,4%) no grupo B (p<0.518). A avaliação tardia demonstrou que 86,4 a 96,0% dos pacientes apresentaram critérios 4 e 5 de SAEED, demonstrando deglutição efetiva e sem diferença significante entre os grupos. Conclusão: A anastomose esofagogástrica pela sutura mecânica é mais adequada que a manual com pequena incidência de complicações locais e, na avaliação em longo prazo, a deglutição demonstrou ser adequada em ambos os grupos e com qualidade semelhante.

ABSTRACT

Abstract INTRODUCTION The diagnosis and classification of megaesophagus can be challenging in patients with Chagas disease. The present study aimed to evaluate the agreement between upper endoscopies and esophagographies for the diagnosis and classification of megaesophagus in Chagas disease. METHODS: A cross-sectional study of 50 patients with Chagas disease with upper digestive symptoms was undertaken. Esophagography and upper endoscopy exams were performed to compare diagnoses. Statistical analysis included sensitivity and specificity used to evaluate the diagnostic accuracy of upper endoscopies, and measures of agreement: linearly weighted Kappa (κw) and Cohen`s classical Kappa (κ) coefficients with 95% confidence intervals (95% CI). RESULTS: Twenty-three patients (46%) were diagnosed with megaesophagus by esophagography. The upper endoscopy sensitivity and specificity for megaesophagus diagnosis were 100% and 33.3%, respectively. Regarding megaesophagus classifications, there was a substantial agreement between the two exams (κw = 0.622; 95% CI: 0.498 to 0.746). Within megaesophagus groups, agreement for group I was slight (κ = 0.096; 95% CI: 0.000 to 0.403); for group II, substantial (κ = 0.703; 95% CI: 0.456 to 0.950); and for groups III and IV, inconclusive (κ = 0.457; 95% CI: 0.000 to 0.967; κ = 0.540; 95% CI: 0.035 to 1.000, respectively). CONCLUSIONS Upper endoscopy has a high sensitivity, but a low specificity to diagnose megaesophagus. Agreement between the two exams varies depending on the megaesophagus grade. Thus, upper endoscopy can be used in the diagnostic workup of a possible Chagas disease megaesophagus, but all identified cases should undergo esophagography.

ABSTRACT

BACKGROUND/AIMS: The influence of external factors such as opioids and alcohol has been extensively investigated for various segments of the gastrointestinal tract. However, the association between their use and the development of esophagogastric junction outflow obstruction disorders (EGJOODs) is unknown. Therefore, the aim of this study is to analyze prevalence and clinical relevance of opioids and alcohol intake in patients with EGJOODs. METHODS: In this single-center, retrospective study, we reviewed clinical and pharmacological data of 375 consecutive patients who had undergone high resolution impedance manometry for EGJOODs. EGJOODs were classified according to the Chicago classification version 3.0 and to recently published normal values for test meals. Demographics, manometric data, and symptoms were compared between different groups using Pearson's chi-squared test, Fisher's exact test, and multivariate analysis. A P < 0.05 was considered significant. RESULTS: EGJOOD was found in 30.7% (115/375) of all analyzed patients. The prevalence of opioids (14.8% vs 4.2%, P = 0.026) was significantly higher in patients with EGJOODs compared to patients without EGJOODs. Additionally, excessive alcohol consumption (12.2% vs 3.5%, P = 0.011) was associated with EGJOODs. Excessive alcohol consumption was especially frequent in the non-achalasia esophagogastric junction outflow obstruction subgroup (16.2%) and opioid use in the achalasia type III subgroup (20.0%). CONCLUSIONS: We found a significant association between EGJOODs and opioid as well as excessive alcohol consumption. This underlines the importance of detailed history taking regarding medication and ethanol consumption in patients with dysphagia. Further prospective studies on mechanisms undelaying esophagogastric junction dysfunction due to opioids or alcohol are warranted.

ABSTRACT

The Chicago classification (CC) defines an esophagogastric junction outflow obstruction (EGJOO) as the presence of several instances of intact or weak peristalsis, elevated median integrated relaxation pressure above 15 mmHg, and a discrepancy from the criteria of achalasia. The revised CC addresses the potential etiology of EGJOO, including the early forms of achalasia, mechanical obstruction, esophageal wall stiffness, or manifestation of hiatal hernia. A 58-year-old woman visited the Presbyterian Medical Center with swallowing difficulty. The patient underwent a high resolution manometry (HRM) examination and was diagnosed with EGJOO. Chest CT was performed to exclude a mechanical obstruction as a cause, and CT revealed a subepithelial tumor (SET) at the upper part of the esophagogastric junction. Therefore, laparoscopic surgery was performed and eccentric muscular hypertrophy of the distal esophagus was observed. Longitudinal myotomy and Dor fundoplication were also performed. The histology findings of the surgical specimens were consistent with achalasia. This paper reports a case of early achalasia that was finally diagnosed by the histology findings, but was initially diagnosed as EGJOO using HRM and misdiagnosed as SET in the image study.
