Résumé
Introduction: achalasia is an esophageal motility disorder, characterized by irregular peristalsis and inadequate relaxation of the lower esophageal sphincter, typically manifests with dysphagia as its primary symptom. The advent of high-resolution manometry (HRM) has transformed our comprehension of achalasia. It has delineated three distinct subtypes based on variations in pressurization and contractions, contributing significantly to the understanding of this condition. This study aimed to describe and compare clinically and manometrically the patients suffering from the different subtypes of achalasia. Methods: it is a retrospective single-center study including all patients with achalasia diagnosed by high-resolution manometry (HRM) between April 2018 and January 2023. The diagnosis was retained based on the latest Chicago 3.0 classification. Results: out of 103 patients, 25.2% (n=26) had type I achalasia, 66.9% (n=69) type II, and 7.8% (n=8) type III. Patients with type I and II achalasia were younger than patients with type III achalasia (mean age 43.2 years vs. 55.6 years, P=0.0053). A female predominance was found in type I achalasia and a male predominance in type III. The most frequent symptoms were: dysphagia (found in all our patients). At HRM, all our patients had a pathological IRP with a mean of 26.95 mmHg for the 3 types of achalasia. Resting IBS pressures were higher in patients with type III achalasia compared to types I and II (35.28 mmHg vs 32.7 mmHg and 31.04 mmHg, P=0.40). Conclusion: achalasia is one of the most studied esophageal motility disorders. Tools such as HRM have permitted us not only to identify achalasia early but also to define different subtypes, which can have therapeutic implications.

ABSTRACT BACKGROUND: Videolaparoscopic esophagocardiomyotomy with fundoplication has been a widely used technique for the treatment of achalasia. This study analyzes the safety and effectiveness of the technique in the treatment of non-advanced achalasia (megaesophagus) in a Brazilian federal university public hospital. AIMS: To evaluate the short- and long-term results of videolaparoscopic treatment of non-advanced megaesophagus in a public university hospital in Brazil, employing the esophagocardiomyotomy technique with fundoplication. METHODS: The medical records of 44 patients who underwent surgical treatment for non-advanced achalasia at the Clinical Hospital of Federal University of Uberlândia (UFU-MG), Minas Gerais, from January 2001 to July 2021 were analyzed. The following data were evaluated: gender, age, etiology, radiological classification of Rezende-Alves and Ferreira-Santos, immediate and late complications (mean follow-up of 31.4 months), need or not for conversion to open access, postoperative reflux, performance or not of endoscopic esophageal dilation in the preoperative period, postoperative mortality, frequency of pre and postoperative symptoms (persistent dysphagia, regurgitation, heartburn, vomiting, odynophagia, and weight loss), surgery time, hospital stay, duration of dysphagia, pre and postoperative weight, and Eckardt score. RESULTS: Among the analyzed patients, 23 (52.3%) were male, and 21 (47.7%) were female, with a mean age of 50.8 years. No early complications were recorded and there were 27.2% cases of late gastroesophageal reflux. Postoperative weight gain was 81.8% and the success rate of surgery according to the Eckardt score was 84.1%. CONCLUSIONS: Esophagocardiomyotomy with fundoplication is an effective and safe technique for the treatment of non-advanced achalasia.
RESUMO RACIONAL: A esofagocardiomiotomia com fundoplicatura videolaparoscópica é uma técnica amplamente utilizada para o tratamento da acalasia. Este estudo avalia se esta técnica é segura e efetiva para o tratamento da acalasia não avançada (megaesôfago) em hospital público federal universitário. OBJETIVOS: Avaliar em um hospital universitário público no Brasil os resultados imediatos e tardios do tratamento videolaparoscópico do megaesôfago não avançado pela técnica de esofagocardiomiotomia com fundoplicatura. MÉTODOS: Foram analisados retrospectivamente os prontuários de 44 pacientes submetidos ao tratamento da acalasia não avançada no Hospital de Clínicas da Universidade Federal de Uberlândia (UFU-MG) no período de janeiro de 2001 até julho de 2021. Avaliou-se: sexo, idade, etiologia, classificação radiológica de Rezende-Alves e Ferreira-Santos, complicações imediatas e tardias (seguimento médio de 31,4 meses), necessidade ou não de conversão para via aberta, refluxo pós-operatório, realização ou não de dilatação endoscópica do esôfago no pré-operatório, mortalidade pós-operatória, frequência dos sintomas no pré e pós-operatório (disfagia persistente, regurgitação, pirose, vômitos, odinofagia e emagrecimento), tempos de cirurgia, internação hospitalar, disfagia, peso pré e pós-operatório e escore de Eckardt. RESULTADOS: Entre os pacientes analisados, 23 (52,3%) eram do sexo masculino e 21 (47,7%) eram do sexo feminino, com média de idade de 50,8 anos. Não foram registradas complicações precoces e houve 27,2% de casos de refluxo gastroesofágico. O ganho de peso no pós-operatório foi de 81,8% e a taxa de sucesso da cirurgia segundo o escore de Eckardt foi de 84,1%. CONCLUSÕES: A esofagocardiomiotomia com válvula antirrefluxo por videolaparoscopia é uma técnica eficaz e segura para o tratamento da acalasia não avançada.
Résumé
ABSTRACT BACKGROUND: Advanced megaesophagus predisposes to risks of malnutrition infections and cancer, in addition to having a significant impact on quality of life. There is currently no consensus in the literature regarding the best surgical option for advanced megaesophagus, although there is a predilection for esophagectomy, despite this surgery being associated with significant morbidity and mortality. Other surgical procedures, such as esophageal mucosectomy and Heller cardiomyotomy, have been proposed with good results. AIMS: To conduct a systematic review and meta-analysis of the literature on the surgical treatment of advanced megaesophagus. METHODS: Databases used included PubMed, Latin American and Caribbean Health Sciences Literature (Lilacs), Embase and Medical Literature Analysis and Retrieval System Online (MedLine), as well as reference research. Two reviewers selected the articles independently. RESULTS: A total of 14 articles were chosen, which included 1,862 patients. The studies were divided into two groups: laparoscopic cardiomyotomy with fundoplication (213 patients) and major surgeries (1,649 patients). The studies yielded mostly good or excellent results regarding late outcomes in both groups. However, there was significant morbidity associated with the major surgeries group. CONCLUSIONS: Laparoscopic Heller myotomy can be performed on patients with advanced megaesophagus, with lower rates of complications and mortality compared to major surgeries, with reservations regarding late outcomes results.
RESUMO RACIONAL: O megaesôfago avançado predispõe riscos clínicos de desnutrição, infecções e neoplasias, além de impacto significativo na qualidade de vida. Não há um consenso atual na literatura ante a melhor opção de seu tratamento cirúrgico, embora haja predileção pela esofagectomia, cirurgia de significativa morbimortalidade associada. Outras modalidades cirúrgicas têm sido propostas, com bons resultados, como a mucosectomia esofágica e a cardiomiotomia laparoscópica à Heller. OBJETIVOS: Realizar uma revisão sistemática com metanálise da literatura acerca do tratamento cirúrgico do megaesôfago avançado. MÉTODOS: As bases de dados utilizadas foram PubMed, Lilacs, Embase e MedLine, além de pesquisas de referências relacionadas. Os artigos foram selecionados por dois revisores independentemente. RESULTADOS: Foram selecionados 14 artigos, que incluem 1.862 pacientes. Os estudos foram divididos em dois grupos: cardiomiotomia laparoscópica com fundoplicatura (213 pacientes) e cirurgias de grande porte (1.649 pacientes). Os estudos analisados evidenciam que ambos os grupos apresentaram resultados semelhantes quanto ao desfecho tardio, considerado majoritariamente bom ou excelente, no entanto, houve significativa morbimortalidade associada ao grupo de cirurgias maiores. CONCLUSÕES: A cardiomiotomia laparoscópica com fundoplicatura pode ser realizada no megaesôfago avançado, com taxas de complicações e mortalidade reduzidas frente às cirurgias de grande porte, porém, com ressalvas quanto ao desfecho tardio a longo prazo.
Résumé
ABSTRACT Background: Chagas disease causes digestive anatomic and functional changes, including the loss of the myenteric plexus and abnormal esophageal radiologic and manometric findings. Objective: To evaluate the association of abnormal esophageal radiologic findings, cardiac changes, distal esophageal contractions, and complaints of dysphagia and constipation in upper (UES) and lower (LES) esophageal sphincter basal pressure in Chagas disease patients. Methods: The study evaluated 99 patients with Chagas disease and 40 asymptomatic normal volunteers. The patients had normal esophageal radiologic examination (n=61) or esophageal retention without an increase in esophageal diameter (n=38). UES and LES pressure was measured with the rapid pull-through method in a 4-channel water-perfused round catheter. Before manometry, the patients were asked about dysphagia and constipation and submitted to electrocardiography and chest radiography. Results: The amplitude of esophageal distal contraction decreased from controls to chagasic patients with esophageal retention. The proportion of failed and simultaneous contractions increased in patients with abnormal radiologic examination (P<0.01). There were no significant differences in UES and LES pressure between the groups. UES pressure was similar between Chagas disease patients with cardiomegaly (n=27, 126.5±62.7 mmHg) and those without it (n=72, 144.2±51.6 mmHg, P=0.26). Patients with constipation had lower LES pressure (n=23, 34.7±20.3 mmHg) than those without it (n=76, 42.9±20.5 mmHg, P<0.03). Conclusion: Chagas disease patients with absent or mild esophageal radiologic involvement had no significant changes in UES and LES basal pressure. Constipation complaints are associated with decreased LES basal pressure.
RESUMO Contexto: Doença de Chagas compromete principalmente o coração e o aparelho digestivo. No esôfago ocorre destruição do plexo mientérico, com alterações radiológicas e manométricas semelhantes às da acalásia idiopática. Objetivo: Avaliar a influência do comprometimento radiológico do esôfago, alterações cardíacas, contrações esofágicas distais e queixas de disfagia e constipação na pressão dos esfíncteres superior (EES) e inferior (EEI) do esôfago. Métodos: Foram avaliados 99 pacientes com exame sorológico positivo para doença de Chagas, com exame radiológico do esofâgo normal (n=61) ou retenção esofágica sem dilatação (n=38), e 40 voluntários normais. A pressão do esfíncter superior e inferior foi medida em triplicata pelo método da retirada rápida do cateter com perfusão de água, em quatro direções dos esfíncteres. Os pacientes foram questionados sobre disfagia e constipação, e foram realizados eletrocardiograma e radiografia de tórax. Resultados: A amplitude da contração distal foi de maior valor dos controles para pacientes com retenção esofágica; a proporção de contrações falhas e simultâneas aumentou em pacientes com exame radiológico anormal (P=0,01). Não houve diferença entre os grupos nas pressões do EES e do EEI. Pacientes com cardiomegalia apresentaram pressão do EES similar (n=27, 126,5±62,7 mmHg) a pacientes sem cardiomegalia (n=72, 144,2 ±51,6 mmHg, P=0,26). Pacientes com constipação apresentaram menor pressão do EEI (n=23, 34,7±20,3 mmHg) do que pacientes sem constipação (n=76, 42,9±20,5 mmHg, P<0,03). Conclusão: Os pacientes com doença de Chagas avaliados não apresentaram alteração significativa na pressão basal do EES e do EEI. Houve associação da queixa de constipação com diminuição da pressão basal do EIE.

Introducción: la acalasia es una entidad poco frecuente en pediatría. Es un desorden de la motilidad esofágica de tipo neurovegetativo, idiopático; aunque también puede ser secundario a infecciones, neoplasias y enfermedades autoinmunes. Se caracteriza por síntomas como disfagia, regurgitaciones, dolor y descenso ponderal. En adultos la manometría de alta resolución es el gold standard. En niños las dificultades técnicas complejizan su realización. En la actualidad la asociación de la impedanciometría intraesofágica con la manometría es el método diagnóstico más eficaz. El objetivo del tratamiento es mejorar el vaciamiento esofágico mediante la disminución del tono del esfínter esofágico inferior por métodos farmacológicos, endoscópicos o quirúrgicos. Actualmente la miotomía de Heller es de elección. Caso clínico: escolar de 6 años, previamente sano, ingresado por regurgitaciones, dolor abdominal y adelgazamiento. Estudio radiográfico con bario con hallazgos compatibles con acalasia esofágica. Se descartaron causas secundarias. El tratamiento definitivo fue la miotomía de Heller con funduplicatura anterior de Dorr, presentando buena evolución clínica. Discusión: si bien la disfagia es el síntoma clave y en general guía el diagnóstico, es importante estar alertas a las formas clínicas atípicas con presentaciones inespecíficas, como en el caso clínico presentado, esto permite establecer un diagnóstico oportuno, evitando el impacto nutricional y psicosocial del niño y su familia.
Introduction: achalasia is a rare entity in pe-diatrics. It is an idiopathic neurovegetative esophageal motility disorder; although it can also be secondary to infections, neoplasias and autoimmune diseases. It is characterized by symptoms such as dysphagia, regurgitation, pain, and weight loss. In adults, high-resolution manometry is the gold standard. In children, technical difficulties complicate its realization. Currently, the association of intraesophageal impedance measurement with manometry is the most effective diagnostic method. The goal of treatment is to improve esophageal emptying by reducing the tone of the lower esophageal sphincter by pharmacological, en-doscopic, or surgical methods. Heller's myotomy is currently the treatment of choice. Clinical case: a 6-year-old schoolboy, previous-ly healthy, admitted for regurgitation, abdomi-nal pain, and weight loss. Barium radiographic study with findings compatible with esopha-geal achalasia. Secondary causes were ruled out. The definitive treatment was Heller's myotomy with Dorr's anterior fundoplication, presenting good clinical evolution. Discussion: although dysphagia is the key symptom and in general it leads the diagnosis, it is important to be aware of atypical clinical forms with non-specific presentations as in the clinical case presented, which allows timely diagnosis, preventing the nutritional and psychosocial impact of the child and his family.
Introdução: a acalasia é uma entidade rara em pediatria. É um distúrbio neurovegetativo da motilidade esofágica idiopática; embora também possa ser secundária a infecções, neoplasias e doenças autoimunes. É caracterizada por sintomas como disfagia, regurgitação, dor e perda de peso. Em adultos, a manometria de alta resolução é o padrão ouro. Nas crianças, as dificuldades técnicas tornam a sua implementação mais complexa. Atualmente, a associação da impedanciometria intraesofágica com a manometria é o método diagnóstico mais eficaz. O objetivo do tratamento é melhorar o esvaziamento esofágico, reduzindo o tônus do esfíncter esofágico inferior por métodos farmacológicos, endoscópicos ou cirúrgicos. Atualmente a miotomia de Heller é de escolha. Caso clínico: escolar de 6 anos, previamente hígido, internado por regurgitação, dor abdominal e emagrecimento. Estudo radiográfico com bário com achados compatíveis com acalasia esofágica. As causas secundárias foram descartadas. O tratamento definitivo foi miotomia de Heller com fundoplicatura anterior de Dorr, com boa evolução clínica. Discussão: embora a disfagia seja o sintoma chave e geralmente oriente o diagnóstico, é importante estar atento às formas clínicas atípicas e com apresentações inespecíficas, como no caso clínico apresentado, isso permite estabelecer um diagnóstico oportuno, evitando o impacto nutricional e psicossocial da criança e de sua família.

La disfagia alta es un síntoma frecuente de consulta al otorrinolaringólogo o gastroenteròlogo. Los diagnósticos diferenciales son trastornos de la deglución por daño neurològico, anillos esofágicos superiores, globus faríngeo, neoplasia, disfagia lusoria y trastornos motores inespecífico y otras más raras aún. Hay escasa literatura actualizada en pacientes adultos. El diagnóstico se basa en el estudio radiológico baritado, endoscopia y complementariamente con manometría. Las opciones de tratamiento son motivo de discusión, dada la poca evidencia disponible. En este artículo se presentan los resultados observados en una cohorte de 10 pacientes con diagnóstico confirmado de acalasia del cricofaríngeo sometidos a dilatación endoscópica (7 pacientes) o miotomía quirúrgica por cervicotomía (3 pacientes). Se evaluó evolución de la disfagia, complicaciones post procedimiento y resultados a largo plazo. No hubo complicaciones mayores, la disfagia mejoro en ambos grupos, en el grupo de dilatación se complementó el tratamiento con dilataciones periódicas en 2 pacientes. No hubo diferencias significativas en los 2 grupos estudiados. Conclusión: ambas opciones terapéuticas presentan buenos resultados en el tratamiento de estos pacientes.
Dysphagia at cervical level is a frequent symptom causing visit to otolaryngologist or gastroenterologist. The differential diagnoses are swallowing disorders due to neurological damage, upper esophageal rings, pharyngeal globus, neoplasia, non-specific motor disorders and other even rarer ones. There is little updated literature in adult patients. The diagnosis is based on the barium radiological study, endoscopy and complementary manometry. Treatment options are a matter of discussion, given the little evidence available. This paper presents the results observed in a cohort of 10 patients with a confirmed diagnosis of cricopharyngeal achalasia who underwent endoscopic dilation (7 patients) or surgical myotomy by cervicotomy (3 patients). The evolution of dysphagia, post-procedure complications and long-term results were evaluated. There were no major complications, dysphagia improved in both groups, in the dilation group the treatment was supplemented with periodic dilations in 2 patients. There were no significant differences in the 2 groups studied. Conclusion: both therapeutic options present good results in the treatment of these patients.
Résumé
Introducción. La acalasia es un trastorno motor del esófago caracterizado por la ausencia de peristalsis y la alteración en la relajación del esfínter esofágico inferior. La cardiomiotomía laparoscópica de Heller más funduplicatura parcial es el tratamiento estándar. La mejoría sintomática ha sido bien documentada, pero no hay suficiente información objetiva respecto a los cambios fisiológicos y radiográficos luego del procedimiento. Métodos. Estudio de cohorte bidireccional de pacientes llevados a cardiomiotomía laparoscópica de Heller, entre los años 2018 y 2021, en el Hospital Universitario San Vicente Fundación de Medellín, Colombia. Se describen variables demográficas y clínicas. Se realizaron puntaje sintomático de Eckardt, manometría esofágica y radiografía de esófago en el pre y postoperatorio. Se hizo comparación de síntomas, presión basal del esfínter esofágico inferior, presión de relajación integrada y diámetro del esófago antes y después de la intervención. Resultados. Se incluyeron 24 pacientes. El 63 % fueron mujeres y la edad promedio fue de 44 años. Los valores promedio preoperatorios vs postoperatorios fueron: puntaje de Eckardt 10,6 vs 1,4 puntos (p<0,001), presión basal de 41,4 vs 18,1 mmHg (p=0,004) y presión de relajación integrada de 28,6 vs 12,5 mmHg (p=0,001). El diámetro del esófago no presentó cambios. No hubo correlación de síntomas con los cambios de presión del esfínter esofágico inferior. El tiempo de seguimiento fue de 20 meses. Conclusiones. La cardiomiotomía de Heller es un procedimiento altamente efectivo para el tratamiento definitivo de la acalasia, logrando una mejoría subjetiva y objetiva basada en síntomas y en parámetros de manometría, respectivamente
Introduction. Achalasia is a motor disorder of the esophagus characterized by the absence of peristalsis and impaired relaxation of the lower esophageal sphincter. Laparoscopic Heller Ìs cardiomyotomy plus partial fundoplication is the standard treatment. Symptomatic improvement has been well documented, but there is insufficient objective information regarding physiologic and radiographic changes after the procedure. Methods. Bidirectional cohort study of patients underwent laparoscopic Heller Ìs cardiomyotomy between 2018 and 2021 at the San Vicente Fundación University Hospital in Medellín, Colombia. Demographic and clinical variables are described. Eckardt symptom score, esophageal manometry, and esophageal radiography were performed pre and postoperatively. A comparison of symptoms, baseline lower esophageal sphincter pressure, integrated relaxation pressure, and esophageal diameter before and after intervention were performed.Results. 24 patients were included. 63% were women and the average age was 44 years. The preoperative vs. postoperative mean values were: Eckardt score 10.6 vs. 1.4 points (p<0.001), basal pressure of 41.4 vs. 18.1 mmHg (p=0.004) and integrated relaxation pressure of 28.6 vs. 12.5 mmHg (p=0.001). The diameter of the esophagus did not present changes. There was no correlation of symptoms with lower esophageal sphincter pressure changes. The follow-up time was 20 months. Conclusions. Heller cardiomyotomy is a highly effective procedure for the definitive treatment of achalasia, achieving subjective and objective improvements, based on symptoms and manometry parameters, respectively

ABSTRACT Objective: This study aimed to evaluate the prevalence of some epidemiologically important comorbidities in patients with Chagas megaoesophagus in relation to the population without megaoesophagus, and whether this condition would be a protective or a risk factor for the conditions analysed. Methods: This observational descriptive study collected data from the medical records of patients with a previous diagnosis of megaoesophagus (timing: from 2005 to 2020). The patients were divided by age into a general (all ages) and an older group (aged 60 years or more). Associations were searched for four main areas/systems/involvements: cardiovascular, respiratory, endocrine and neurological. Results: The general group included 546 patients and the older group included 248 patients. As for the prevalence of comorbidities in the general group, the three most prevalent diseases were hypertension, with 44.3% (CI95%: 40.21-48.51%); dyslipidaemia, with 17.8% (CI95%: 14.79-21.19%); and heart failure, with 15.2% (CI95%: 12.43-18.45%). Similar to that in the general group, the most prevalent comorbidities in the group of older patients were hypertension, dyslipidaemia, and heart failure. Conclusion: Systemic arterial hypertension, dyslipidaemia, and heart failure were the most prevalent comorbidities in this population. The lower prevalence of diabetes mellitus and Alzheimer's disease suggests the association of enteric nervous system denervation and requires further investigation.
RESUMO Objetivo: Este estudo teve como objetivo avaliar a prevalência de algumas comorbidades epidemiologicamente importantes em pacientes com megaesôfago chagásico em relação à população sem o megaesôfago e se essa condição seria um fator protetor ou de risco para as condições analisadas. Métodos: Este estudo descritivo observacional coletou dados de prontuários de pacientes com diagnóstico prévio de megaesôfago (período: de 2005 a 2020). Os pacientes foram divididos por idade em um grupo geral (todas as idades) e um grupo idoso (60 anos ou mais). Foram pesquisadas associações para quatro áreas/sistemas/envolvimentos principais: cardiovascular, respiratório, endócrino e neurológico. Resultados: O grupo geral incluiu 546 pacientes e o grupo idosos incluiu 248 pacientes. Quanto à prevalência de comorbidades no grupo geral, as três doenças mais prevalentes foram hipertensão, com 44,3% (IC95%: 40,21-48,51%); dislipidemia, com 17,8% (IC95%: 14,79-21,19%); e insuficiência cardíaca, com 15,2% (IC95%: 12,43-18,45%). Assim como no grupo geral, as comorbidades mais prevalentes no grupo de idosos foram hipertensão, dislipidemia e insuficiência cardíaca. Conclusão: Hipertensão arterial sistêmica, dislipidemia e insuficiência cardíaca foram as comorbidades mais prevalentes nessa população. A menor prevalência de diabetes mellitus e doença de Alzheimer sugere uma associação de denervação do sistema nervoso entérico e requer mais investigação.
Résumé
Introduction: Laparoscopic Heller myotomy (LHM) is widely recognized as the standard surgical treatment for esophageal achalasia. However, there is a lack of local data regarding the clinical characteristics of patients and the outcomes of this intervention. Methodology: This retrospective study analyzed patients who underwent LHM over an eight-year period. Demographic, operative, and postoperative variables were assessed. The Eckardt score was used to compare symptoms before and after the intervention. Continuous variables were presented as means. Results: Among the 39 patients assessed, 27 met the inclusion criteria. Of these, 51% were male, with an average age of 48 years. The average lower esophageal sphincter pressure was 36 mmHg. The mean operative time and bleeding were 133 minutes and 34 mL, respectively. The average length of the myotomy was 8.3 cm. Partial fundoplication was performed in all cases, and intraoperative endoscopy was conducted in 88% of the cases. Two intraoperative mucosal perforations occurred. The average length of hospital stay was 2.7 days. There was one medical complication but no mortality. Dysphagia significantly improved by 95%, and the mean Eckardt score decreased from 7.7 to 1.2 after surgery (p < 0.001). The average follow-up period was 24 months. Conclusion: LHM with partial fundoplication proves to be an effective and safe procedure for treating achalasia. It results in the resolution of dysphagia in 95% of cases and carries minimal morbidity. Therefore, LHM should be considered the definitive treatment of choice for achalasia.
Introducción: la miotomía de Heller laparoscópica (MHL) se considera el tratamiento quirúrgico estándar en acalasia esofágica. A nivel local se desconocen las características clínicas de los pacientes y los resultados de la intervención. Metodología: estudio retrospectivo que incluye pacientes llevados a MHL durante un periodo de 8 años. Se analizaron variables demográficas, operatorias y posoperatorias. Mediante el puntaje de Eckardt se compararon síntomas antes y después de la intervención. Las variables continuas se expresan en promedios. Resultados: 27 de 39 pacientes cumplieron los criterios de inclusión. El 51% fueron hombres y el promedio de edad fue de 48 años. La presión promedio del esfínter esofágico inferior fue de 36 mm Hg. El promedio de tiempo operatorio y sangrado fue de 133 minutos y 34 mL, respectivamente. La longitud promedio de la miotomía fue de 8,3 cm. Se adicionó funduplicatura parcial en todos los casos y en el 88% se realizó una endoscopia intraoperatoria. Se presentaron 2 perforaciones intraoperatorias de la mucosa. El promedio de estancia hospitalaria fue 2,7 días. Hubo una complicación médica y ninguna mortalidad. La disfagia mejoró en el 95% y el promedio del puntaje de Eckardt disminuyó de 7,7 a 1,2 luego de cirugía (p < 0,001). El seguimiento fue de 24 meses en promedio. Conclusión: la MHL con funduplicatura parcial es un procedimiento efectivo y seguro para el tratamiento de la acalasia. Se asocia a resolución de la disfagia en el 95% de los casos, su morbilidad es mínima y debe considerarse el tratamiento definitivo de elección.
Résumé
Introduction: Limited information is available regarding the clinical and manometric characteristics of different subtypes of achalasia. This study aims to describe these characteristics in patients treated at a prominent hospital in Colombia. Methods: This descriptive observational study included patients diagnosed with achalasia using high-resolution esophageal manometry at Hospital Universitario San Ignacio in Bogotá, Colombia, between 2016 and 2020. We documented the clinical manifestations, manometric findings, treatment approaches, and response to treatment based on the subtype of achalasia. Results: A total of 87 patients were enrolled, with a median age of 51 years, and 56.4% of them were female. The majority had type II achalasia (78.1%), followed by type I (16%) and type III (5.7%). All patients presented with dysphagia, 40.2% experienced chest pain, and 27.6% had gastroesophageal reflux. The clinical parameters, including integrated relaxation pressure value (IRP; median: 24 mmHg, interquartile range [IQR]: 19-33), upper esophageal sphincter pressure (UES; median: 63 mmHg, IQR: 46-98), and lower esophageal sphincter pressure (LES; median: 34 mm Hg, IQR: 26-45), were similar across the different subtypes. Esophageal clearance was incomplete in all patients. Among the 35 patients who received intervention, Heller's myotomy was the most commonly employed procedure (68.5%), followed by esophageal dilation (28.6%). All patients experienced symptomatic improvement, with a median pre-treatment Eckardt score of 5 (IQR: 5-6) and a post-treatment score of 1 (IQR: 1-2). Conclusions: Type II achalasia is the most prevalent subtype. The clinical and manometric findings, as well as treatment response, exhibit similarities among the different subtypes of achalasia. In Colombia, the outcomes of this condition align with those reported in other parts of the world.
Introducción: existe información limitada sobre las características clínicas y manométricas de los diferentes subtipos de acalasia. Este estudio describe dichas características en pacientes manejados en un hospital de referencia en Colombia. Método: estudio descriptivo observacional que incluye a pacientes con diagnóstico de acalasia por manometría esofágica de alta resolución manejados en el Hospital Universitario San Ignacio de Bogotá, Colombia, entre 2016 y 2020. Se describen las manifestaciones clínicas, hallazgos manométricos, tratamiento utilizado y respuesta al mismo según el subtipo de acalasia. Resultados: se incluyeron a 87 pacientes (mediana de edad: 51 años, 56,4% mujeres). La mayoría de tipo II (78,1%), seguido por tipo I (16%) y tipo III (5,7%). Todos presentaron disfagia, 40,2% dolor torácico y 27,6% reflujo gastroesofágico. La clínica y los valores del integral de presión de relajación (IRP; mediana: 24 mm Hg, rango intercuartílico [RIC]: 19-33), presión del esfínter esofágico superior (EES; mediana: 63 mm Hg, RIC: 46-98) y presión del esfínter esofágico inferior (EEI; mediana: 34 mm Hg, RIC: 26-45) fueron similares en los diferentes subtipos. El aclaramiento esofágico fue incompleto en todos los pacientes. Entre 35 pacientes que recibieron manejo intervencionista, la miotomía de Heller fue la intervención más utilizada (68,5%), seguido por la dilatación esofágica (28,6%). La totalidad de estos pacientes presentó una mejoría sintomática con la mediana de Eckardt pretratamiento de 5 (RIC: 5-6) y postratamiento de 1 (RIC: 1-2). Conclusiones: la acalasia tipo II es la más común. La clínica y los hallazgos manométricos y respuesta a tratamiento son similares entre los subtipos de acalasia. En Colombia, esta entidad se comporta de forma similar a lo reportado en otras partes del mundo.

Objective:To evaluate the efficacy and safety of peroral endoscopic myotomy (POEM) in achalasia of cardia (AC) patients with the long course.Methods:A total of 159 AC patients who received POEM from January 2015 to March 2022 in the First Affiliated Hospital of Soochow University were divided into the long course group (≥10 years) and the non-long course group (<10 years). The baseline information, POEM procedure and postoperative recurrence were compared and the differences between the recurrent patients and non-recurrent patients in the long course group were explored.Results:The age (57.09±14.30 years VS 42.08±15.68 years, t=5.569, P<0.001), the rate of treatment history [28.9% (13/45) VS 9.6% (11/114), χ2=9.319, P=0.020], the proportion of Henderson grade Ⅲ esophagus [17.8% (8/45) VS 6.1% (7/114), χ2=7.020, P=0.030] in the long course group were significantly higher than those in the non-long course group. The recurrence rate in the long course group was significantly higher than that in the non-long course group [33.3% (15/45) VS 14.9% (17/114), χ2=6.811, P=0.009]. In the long course group, the age (62.50 ± 16.94 years VS 53.77 ± 12.95 years, t=-2.121, P=0.040), and the rate of treatment history [53.3% (8/15) VS 16.7% (5/30), χ2=6.544, P=0.016] in the recurrent patients were higher than those in the non-recurrent patients. Conclusion:POEM is safe and effective for long-course AC patients. In patients with the long course, the aged patients with previous treatment are more likely to relapse.
Résumé
In order to evaluate the efficacy of peroral endoscopic myotomy (POEM) for achalasia, data of 63 patients with achalasia who were treated with POEM in China-Japan Union Hospital of Jilin University from 2017 to 2021 were collected. Postoperative Eckardt score, high-resolution manometry and upper gastrointestinal radiography were compared with preoperative data. The mean age of the 63 patients was 49.0 years, and there were 31 famales. The preoperative Eckardt score was 9 (3), and the postoperative Eckardt score was 2 (2), with significant difference ( V=1 953, P<0.001). The lower esophageal sphincter pressure decreased significantly after operation compared with that before operation [9.90 (3.35) mmHg VS 26.80(13.85)mmHg, V=2 016, P<0.001]. Fifty-three patients (84.1%) had satisfactory curative effects. The incidence of adverse events was 3.2% (2/63). POEM is safe, effective and minimally invasive for the treatment of achalasia.

Objective:To explore the therapeutic effect of peroral endoscopic myotomy (POEM) for primary achalasia (AC) in patients aged over 60 years.Methods:Data of 146 patients aged ≥60 years (the elderly group) and 146 patients aged 18-59 years (the adult group) who received POEM from November 2010 to September 2019 at the Digestive Endoscopy Center of PLA General Hospital were retrospectively analyzed. Baseline data, surgery data, surgery-related complications and surgery-related efficacy were compared.Results:There was no significant difference in gender, Ling classification, HRM classification or previous treatment between the two groups ( P>0.05). All 292 patients successfully underwent POEM surgery. The clinical success (Eckardt score ≤3) rates in the elderly group and the adult group were 96.33% (105/109) and 96.77% (90/93), respectively with no significant difference between the two groups ( χ2=0.030, P>0.05). There was no significant difference in the length of myotomy between the two groups (7.09±2.49 cm VS 7.12±2.24 cm, t=0.472, P>0.05). Complications occurred in 26 cases (17.81%) in the elderly group and 21 cases (14.38%) in the adult group with no significant difference between the two groups ( χ2=0.634, P>0.05). There was no significant difference in the postoperative hospital stay (12.61±9.69 days VS 11.00±4.43 days, t=1.825, P>0.05) or the incidence of gastroesophageal reflux [43.33% (13/30) VS 51.52% (17/33), χ2=0.422, P>0.05] between the elderly group and the adult group. Conclusion:The efficacy of POEM for AC patients over 60 years old is equivalent to that of adult patients, and the incidence of complications is similar. POEM is safe and effective for AC patients over 60 years old.

Objective:To discuss the clinical manifestations, diagnosis and treatment of a patient with Allgrove syndrome.Methods:Retrospective analysis of the clinical data of a patient with Allgrove syndrome admitted to Gansu Provincial People's Hospital on August 8, 2018, and review of relevant literature.Results:The patient, female, 20 years old, presented with dysphagia for 10 years and aggravated for 4 years. No tears since childhood. The upper digestive tract barium meal showed that lower esophageal stenosis, a "beak" shaped change. Esophageal manometry suggested multiple peristalsis failures. Laboratory tests showed low plasma cortisol and high ACTH. The clinical diagnosis was Allgrove syndrome. POME was performed to improve dysphagia, and hormone replacement therapy was given. The symptoms were improved after long-term follow-up.Conclusion:Allgrove syndrome is a multisystem disease. The possibility of Allgrove syndrome should be vigilant when suspicious symptoms appear. If necessary, gene detection is helpful for early diagnosis.Treatment, which focuses on the appropriate management of the manifested signs and symptoms, requires the mutual assistance of multiple disciplines.
Résumé
OBJECTIVES@#At present, there are many reports about the treatment of cricopharyngeal achalasia by injecting botulinum toxin type A (BTX-A) into cricopharyngeal muscle guided by ultrasound, electromyography or CT in China, but there is no report about injecting BTX-A into cricopharyngeal muscle guided by endoscope. This study aims to evaluate the efficacy of endoscopic BTX-A injection combined with balloon dilatation in the treatment of cricopharyngeal achalasia after brainstem stroke, and to provide a better method for the treatment of dysphagia after brainstem stroke.@*METHODS@#From June to December 2022, 30 patients with cricopharyngeal achalasia due to brainstem stroke were selected from the Department of Rehabilitation Medicine, the First Hospital of Changsha. They were randomly assigned into a control group and a combined group, 15 patients in each group. Patients in both groups were treated with routine rehabilitation therapy, while patients in the control group were treated with balloon dilatation, and patients in the combined group were treated with balloon dilatation and BTX-A injection. Before treatment and after 2 weeks of treatment, the patients were examined by video fluoroscopic swallowing study, Penetration-aspiration Scale (PAS), Dysphagia Outcome Severity Scale (DOSS), and Functional Oral Intake Scale (FOIS) were used to assess the swallowing function.@*RESULTS@#In the combined group, 1 patient withdrew from the treatment because of personal reasons. Two weeks after treatment, the scores of DOSS, PAS, and FOIS in both groups were better than those before treatment (all P<0.01), and the combined group was better than the control group (all P<0.001). The effective rate was 85.7% in the combined group and 66.7% in the control group, with no significant difference between the 2 groups (P>0.05).@*CONCLUSIONS@#BTX-A injection combined with balloon dilatation is more effective than balloon dilatation alone in improving swallowing function and is worthy of clinical application.

ABSTRACT BACKGROUND: Achalasia is an esophageal motility disorder, with clinical presentation of dysphagia and regurgitation. This is a chronic condition with no cure. Current treatment options aim to reduce lower esophageal sphincter tone by pharmacological, endoscopic or surgical means, with the aim of improving patients' symptoms. Peroral endoscopic myotomy (POEM) is an alternative endoscopic surgery to Heller cardiomyotomy, in which the procedure is performed orally, by endoscopy, offering efficacy comparable to surgical myotomy, with relative ease and minimal invasion, without external incisions. AIMS: To study the safety of POEM by analyzing its results, adverse events and perioperative complications and the main ways to overcome them, in addition to evaluating the effectiveness of the procedure and the short-term postoperative quality of life. METHODS: A qualitative and quantitative, observational and cross-sectional study that analyzed patients who underwent the POEM in a reference center, from December 2016 to December 2022, maintaining the technical standard of pre-, peri- and postoperative protocol. RESULTS: A total of 94 patients were included in the study, and only three had postoperative complications. The average early postoperative Eckardt score was 0.93 and the late 1.40, with a mean improvement of 7.1 in early results and 6.63 in late results (p<0.05). CONCLUSIONS: POEM can be reproduced with an excellent safety profile, significant relief of symptoms and improvement in esophageal emptying, and in quality of life.
RESUMO RACIONAL: A acalasia é uma desordem da motilidade esofágica, com apresentação clínica de disfagia e regurgitação, uma condição crônica sem cura. As opções de tratamentos atuais visam reduzir o tônus do esfíncter esofagiano inferior (EEI) por meios farmacológicos, endoscópicos ou cirúrgicos, com o objetivo de aliviar os sintomas dos pacientes. A miotomia endoscópica peroral, sigla do inglês (POEM) é uma cirurgia endoscópica alternativa à cardiomiotomia a Heller (CH), em que a miotomia é realizada por via oral, por endoscopia, oferecendo eficácia comparável a miotomia cirúrgica, com relativa facilidade e mínima invasão, sem incisões externas. OBJETIVOS: Analisar a segurança do POEM analisando seus resultados, eventos adversos, complicações perioperatórias e suas principais formas de contorná-los, além de avaliar a eficácia do procedimento e a qualidade de vida pós-operatória, em curto prazo. MÉTODOS: Estudo qualitativo e quantitativo, observacional e transversal avaliando pacientes que realizaram o POEM em um centro de referência, entre dezembro de 2016 até dezembro de 2022, mantendo padrão técnico de preparo pré, peri e pós-operatório. RESULTADOS: Foram incluídos no estudo 94 pacientes e apenas 3 apresentaram complicações pós-operátorias. O escore de Eckardt médio precoce pós-operatório foi de 0,93 e o tardio de 1,40, com melhora média de 7,1 em resultados precoces e de 6,63 em resultados tardios (p<0,05). CONCLUSÕES: O POEM pode ser reproduzido com excelente perfil de segurança, alívio significativo dos sintomas e melhora do esvaziamento do esôfago, oferecendo melhora na qualidade de vida.
Résumé
ABSTRACT BACKGROUND: Achalasia is an esophageal motility disorder, and myotomy is one of the most used treatment techniques. However, symptom persistence or recurrence occurs in 9 to 20% of cases. AIMS: This study aims to provide a practical approach for managing the recurrence or persistence of achalasia symptoms after myotomy. METHODS: A critical review was performed to gather evidence for a rational approach for managing the recurrence or persistence of achalasia symptoms after myotomy. RESULTS: To properly manage an achalasia patient with significant symptoms after myotomy, such as dysphagia, regurgitation, thoracic pain, and weight loss, it is necessary to classify symptoms, stratify severity, perform appropriate tests, and define a treatment strategy. A systematic differential diagnosis workup is essential to cover the main etiologies of symptoms recurrence or persistence after myotomy. Upper digestive endoscopy and dynamic digital radiography are the main tests that can be applied for investigation. The treatment options include endoscopic dilation, peroral endoscopic myotomy, redo surgery, and esophagectomy, and the decision should be based on the patient's individual characteristics. CONCLUSIONS: A good clinical evaluation and the use of proper tests jointly with a rational assessment, are essential for the management of symptoms recurrence or persistence after achalasia myotomy.
RESUMO RACIONAL: A acalasia é um distúrbio da motilidade esofágica e a miotomia é uma das técnicas de tratamento mais utilizadas. No entanto, a persistência ou recorrência dos sintomas ocorre em 9 a 20%. OBJETIVOS: Este estudo visa fornecer uma abordagem prática para o manejo da recorrência ou persistência dos sintomas de acalasia após miotomia. MÉTODOS: Foi realizada uma revisão crítica para reunir evidências para uma abordagem racional no manejo da recorrência ou persistência dos sintomas de acalasia após miotomia. RESULTADOS: Para o manejo adequado de um paciente com acalásia com sintomas significativos após miotomia, como disfagia, regurgitação, dor torácica e perda de peso, é necessário classificar os sintomas, estratificar a gravidade, realizar exames adequados e definir uma estratégia de tratamento. Uma investigação diagnóstica diferencial sistemática é essencial para cobrir as principais etiologias de recorrência ou persistência dos sintomas após a miotomia. A endoscopia digestiva alta e a radiografia digital dinâmica são os principais exames que podem ser aplicados para investigação. As opções de tratamento incluem dilatação endoscópica, POEM (miotomia endoscópica oral), remiotomia e esofagectomia, e a decisão deve ser baseada nas características individuais do paciente. CONCLUSÕES: Uma boa avaliação clínica e a utilização de exames adequados, juntamente com uma avaliação racional, são essenciais para o manejo da recorrência ou persistência dos sintomas após miotomia por acalasia.
Résumé
ABSTRACT Background: Advanced achalasia cardia (AC) represents the end stage in the natural history of AC. Role of per oral endoscopic myotomy (POEM) in this technically difficult subset is emerging. Methods: Retrospective review of the patients who had undergone POEM for advanced AC with sigmoid esophagus. We assessed the technical success, clinical success and adverse event rate. Pre and post POEM Eckardt score (ES), integrated relaxation pressure-4sec (IRP-4), lower oesophageal sphincter pressure (LESP) and height and width of barium column at 5 minutes were noted. Results: Of the 85 patients who underwent POEM for AC, 10 patients had advanced AC with sigmoid esophagus of which eight were sigmoid and two were advanced sigmoid. The clinical and technical success was 100% with significant reduction of ES, IRP-4, LESP and height and width of barium column at 5 minutes. One patient had a minor adverse event in the form of mucosal injury that was closed with hemoclips. At a median follow up of 17 months there was no recurrence. Conclusion: Our study demonstrates POEM to be a safe and effective modality of treatment in this technically difficult subset of AC with sigmoid morphology.
RESUMO Contexto: Acalasia cárdia avançada representa o estágio final na história natural do megaesôfago. Está emergindo o papel da miotomia endoscópica peroral (POEM) neste subconjunto tecnicamente difícil. Métodos: Foi realizada uma revisão retrospectiva dos pacientes submetidos a POEM para tratamento do megaesôfago avançado. Avaliamos o sucesso técnico, o sucesso clínico e a taxa de eventos adversos. O escore de Eckardt, pré e pós POEM, a pressão integral de relaxamento de 4 seg (IRP-4), a pressão do esfíncter inferior do esôfago e a altura e largura da coluna de bário em 5 minutos, foram anotadas. Resultados: Dos 85 pacientes submetidos a POEM para acalasia cárdia, 10 pacientes apresentaram acalasia cárdia avançado com esôfago com aspecto sigmoide, dos quais dois eram muito avançados. O sucesso clínico e técnico foi de 100% com redução significativa do escore de Eckardt, do IRP-4, da pressão do esfíncter inferior do esôfago e da altura e largura da coluna bário em 5 minutos. Um paciente teve um pequeno evento adverso na forma de lesão mucosa que foi fechada com hemoclipes. Em um seguimento mediano de 17 meses não houve recorrência. Conclusão: Nosso estudo demonstra que a POEM é uma modalidade segura e eficaz de tratamento neste subconjunto tecnicamente difícil de megaesôfago com morfologia sigmoide.
Résumé
Achalasia is caused by chronic degeneration of ganglionic cells in the myenteric plexus that leads to failure of relaxation of the lower esophageal sphincter (LES). This leads to aperistalsis of the digital esophagus and eventually led to dilation of the lower esophagus. We present the case of a 37-year-old man who initially presented with dysphagia for solid food and then slowly developed dysphagia for liquid over the past 6 months. He had significant weight loss, and his esophagogastroduodenoscopy (EGD) showed esophagitis and gastritis. The imaging of computed tomography (CT) with oral contrast showed dilation of the distal esophagus and mild circumferential thickening at the gastroesophageal junction. After the failure of response to BoTox-infiltration in the LES, the patient was taken for Heller抯 myotomy. He showed immediate improvement in dysphagia after surgical intervention. This case study includes findings from CT scan, X-ray, and EGD with biopsies in this patient. This paper also summarizes the therapeutic options of BoTox-injection and surgical myotomy.
