These lesions would be better evaluated if systematic biopsies were performed in our patients

Development and thoughts of digestive endoscopy in children / 中国当代儿科杂志

After nearly 40 years of development, digestive endoscopy in children has been widely applied, and it has helped to expand the spectrum of pediatric digestive system diseases and greatly improve the diagnosis and treatment of pediatric digestive system diseases. Pediatric digestive endoscopy has become a subject. However, there are some problems such as the unbalanced development of pediatric digestive endoscopy across China, the lack of homogeneity in diagnosis and treatment system, the tendency of adult-oriented diagnosis and treatment techniques, and the localization of training quality, which affect the standardized and healthy development of pediatric digestive endoscopy. The diagnosis and treatment with digestive endoscopy in children should adhere to both pediatric characteristics and technological innovation to propose the concept of comfort, emphasize the importance of standardization (including the space and process for endoscopic diagnosis and treatment, perioperative evaluation, training mode, and access qualification), standardize the minimally invasive techniques, and develop artificial intelligence. It is of great importance to formulate related consensus statements and guidelines on the basis of medical safety and the features of the growth and development of children, so as to achieve the high-quality development of pediatric digestive endoscopy, effectively improve the diagnosis and treatment levels of pediatric digestive endoscopy, and bring benefits to more pediatric patients.

Acercamiento a la terapia antiplaquetaria en el contexto de la endoscopia digestiva / Approach to antiplatelet therapy in the context of digestive endoscopy

Introducción: El empleo de agentes antiagregantes plaquetarios se ve cada día más extendido en la población mundial. La decisión en relación al manejo endoscópico de este tratamiento debe estar basada en el tipo de indicación médica que justifica el uso de estos medicamentos. Se realizó una revisión de los artículos publicados en las bases de datos Pubmed, Scielo, Medline y Cochrane, relacionados con el tema. Objetivo: Profundizar en los conocimientos relacionados con la terapia antiplaquetaria periendoscópica digestiva. Desarrollo: Los antiagregantes plaquetarios son clave en el tratamiento y prevención de eventos trombóticos vasculares, cardíacos o cerebrales. Se han establecido las indicaciones de los antitrombóticos, también se ha evaluado el riesgo tromboembólico al suspender el tratamiento. El riesgo tromboembólico puede ser bajo o alto, por lo que se debe evaluar el riesgo - beneficio de suspender la terapia en este contexto. Todos los procedimientos endoscópicos presentan un riesgo de hemorragia, se considera el bajo riesgo de sangrado por debajo del 1 y alto riesgo por encima del 1 por ciento. La decisión acerca de la antiagregación en el periodo perioperatorio/ periprocedimiento, no solo depende del balance entre el riesgo trombótico y hemorrágico, sino también del tipo y la indicación del tratamiento antiplaquetario. Conclusiones: La antiagregación plaquetaria en pacientes que serán sometidos a procederes gastrointestinales intervencionistas se observa cada vez con mayor frecuencia. Esto hace necesario el conocimiento acerca de la valoración del riesgo de fenómenos trombóticos al interrumpir estos fármacos, junto con la determinación del riesgo potencial de sangrado según el procedimiento endoscópico realizado(AU)

Introduction: The use of platelet antiaggregant agents is increasingly widespread in the world population. The decision regarding the endoscopic management of this treatment should be based on the type of medical indication that justifies the use of these medications. A review of the articles published in the Pubmed, Scielo, Medline and Cochrane databases related to the subject was made. Objective: To deepen the knowledge related to periendoscopic digestive antiplatelet therapy. Development: Platelet antiaggregant are key in the treatment and prevention of vascular, cardiac or cerebral thrombotic events. Just as the indications of antithrombotic agents have been established, the thromboembolic risk has also been evaluated when treatment is suspended. The thromboembolic risk may be low or high, so the risk-benefit of discontinuing therapy in this context should be evaluated. All endoscopic procedures present a risk of bleeding considering the low risk of bleeding below 1 percent and high risk above 1 percent. The decision about anti-aggregation in the perioperative / periprocedural period depends not only on the balance between thrombotic and hemorrhagic risks, but also on the type and indication of antiplatelet therapy. Conclusions: Platelet anti-aggregation in patients who will undergo interventional gastrointestinal procedures is observed more and more frequently. This makes knowledge about the risk assessment of thrombotic phenomena necessary when interrupting these drugs, together with the determination of the potential risk of bleeding according to the endoscopic procedure performed(AU)

Endoscopic diagnosis and treatment of gastrointestinal neuroendocrine neoplasms / 中华胃肠外科杂志

The incidence of neuroendocrine neoplasms (NEN) is increasing globally, and gastrointestinal NEN (GI-NEN) is the most common type of NEN. Diagnosis and treatment of GI-NEN are quite different, according to tumor's location, size, background, cell origin, and pathogenesis. Digestive endoscopy has unique advantages in detecting of GI-NEN. However, endoscopist should not perform endoscopic resection arbitrarily, due to the high heterogeneity and complexity of GI-NEN. We need to establish the concept about comprehensive assessment for GI-NEN, including medical history and physical signs, serology, imaging, radionuclide and end·oscopic examination, to make an individualized treatment after rigorous multidisciplinary discussion.

Analysis of the influencing factors of recurrence of non-variceal upper gastrointestinal bleeding after endoscopic treatment / 国际生物医学工程杂志

Objective:To analyze the factors affecting the recurrence of patients with non-varices upper gastrointestinal bleeding (NVUGIB) after receiving digestive endoscopy.Methods:The clinical data of 120 patients with NVUGIB who received digestive endoscopy were retrospectively analyzed. The patients were divided into recurrence group and non-recurrence group according to their recurrence status, and the risk factors affecting recurrence were analyzed.Results:The results of univariate analysis showed that there was no significant difference in age, gender and body mass index between the relapsed group and the non-relapsed group (all P>0.05), and there was significant difference in Forrest grade, hemoglobin concentration, platelet count, peptic ulcer, shock, improper diet, premature getting out of bed, constipation and subsequent proton pump inhibitors (all P<0.05). The results of multivariate logistic regression analysis showed that the Forrest grade(Ⅰa), hemoglobin level (<100 g/L), platelet count (<100×10 9/L), peptic ulcer, shock, improper diet, premature getting out of bed, constipation and subsequent proton pump inhibitorsare the risk factors of recurrence in patients with NVUGIB (all P<0.05). Conclusions:Clinically, targeted preventive measures should be taken based on the risk factors that affect the recurrence of patients with NVUGIB after digestive endoscopic treatment.

Posible sangrado del intestino delgado. ¿Es la videocápsula endoscópica la mejor opción? / Is the videocapsule endoscopy the best option for diagnosis of possible bleeding from the small intestine?

Resumen En pacientes sin una causa clara de sangrado gastrointestinal luego de una endoscopia digestiva alta y baja, la causa se encontrará en el intestino delgado hasta en el 77 % de los casos. Ante el excelente rendimiento diagnóstico de la videocápsula endoscópica (VCE) para el estudio de este segmento del tracto gastrointestinal, surge la duda de si debería ser el método diagnóstico inicial de este grupo de pacientes con posible sangrado del intestino delgado (PSID) o si la realización de una nueva endoscopia alta y baja o algún método alternativo de estudio del intestino delgado debería serlo. En esta revisión se evalúa y evidencia el rendimiento diagnóstico superior y la mayor seguridad de la VCE como abordaje inicial de pacientes con PSID en relación con otros métodos. Sin embargo, se pone en tela de juicio la mejor costo-efectividad de este abordaje en nuestro medio, que en otros ha sido claramente demostrada.

Abstract When neither upper nor lower gastrointestinal endoscopy can find a clear cause of gastrointestinal bleeding, it will eventually be found in the small intestine in up to 77% of cases. Given the excellent diagnostic performance of video capsule endoscopy for studying this segment of the gastrointestinal tract, the question of whether it should become the initial diagnostic method for patients with possible bleeding from the small intestine arises. The alternatives are to perform additional upper and lower endoscopic procedures or to use some alternative method of studying the small intestine. This review documents and evaluates the superior diagnostic performance and greater safety of videocapsule endoscopy as the initial approach for possible bleeding from the small intestine and compares it with other methods. However, the cost-effectiveness of this approach, clearly demonstrated elsewhere, is questioned in our setting.

Introducción: la COVID-19 es la enfermedad causada por la infección del nuevo coronavirus SARS-CoV-2 descubierta a finales del año 2019 en China y que ha provocado millones de enfermos en todo el mundo. Objetivo: describir las características del trabajo durante la pandemia de COVID-19 en endoscopia digestiva. Material y métodos: se realizó una revisión bibliográfica utilizando bases de datos, guías y buscadores. Se utilizó información de sitios nacionales e internacionales. Se analizó la calidad y validez de los artículos seleccionados. Desarrollo: la transmisión del SARS-CoV-2 se ha determinado por varias vías, la más aceptada es la respiratoria mediante la generación de aereosoles, los cuales son producidos también a través de los procederes endoscópicos. Por tal razón se han establecido diferentes guías y protocolos asistenciales para la realización de endoscopias seguras para los pacientes y personal de endoscopia. Conclusiones: Frente a la pandemia del COVID-19 la estrategia más importante es la prevención que pone a prueba los sistemas de salud del mundo y en práctica formas ajustadas de atención médica para evitar la propagación de la enfermedad en pacientes y personal sanitario(AU)

Introduction: COVID-19 is the disease caused by the infection of the new SARS-CoV-2 coronavirus which was discovered at the end of 2019 in China and has caused millions of patients worldwide. Objective: To describe the work characteristics related to digestive endoscopy during the COVID-19 pandemic. Material and methods: A bibliographic review was carried out using bibliographic databases, guides and search engines. Information from national and international sites was used. The quality and validity of the selected articles were analyzed. Development: The transmission of SARS-CoV-2 has been determined by several routes, the respiratory one being the most accepted in which there is a generation of aerosols that are also produced through endoscopic procedures. For this reason, different guidelines and care protocols have been established to perform safe endoscopies for patients and endoscopy personnel. Conclusions: In the face of the COVID-19 pandemic, prevention is the most important strategy, putting the world's health systems to the test and implementing adjusted forms of medical care to prevent the spread of the disease in patients and healthcare personnel(AU)

Esofagite eosinofílica numa consulta de alergia alimentar: caracterização e comparação entre idade pediátrica e idade adulta / Eosinophilic esophagitis at a food allergy appointment: characterization and comparison between pediatric and adult ages

Introdução: Esofagite eosinofílica (EoE) é uma doença inflamatória crônica do esôfago, mediada imunologicamente e caracterizada por sintomas relacionados com disfunção esofágica e infiltração da mucosa esofágica por eosinófilos (Eo). Os objetivos foram caracterizar os doentes com diagnóstico de EoE e analisar as diferenças entre doentes com diagnóstico em idade pediátrica (Cr, < 18 anos) e adulta (Ad, ≥ 18 anos). Métodos: Estudo observacional retrospetivo dos doentes seguidos no serviço de Imunoalergologia, no período de Fev/2009 a Jul/2017, com diagnóstico de EoE. Foram divididos em dois grupos, Cr e Ad, caracterizados de acordo com dados demográficos, história de atopia, sintomas, sensibilizações alimentares, IgE Total, eosinofilia, achados na endoscopia digestiva alta e biópsias. Avaliou-se a correlação entre sensibilização alimentar, clínica grave (ClinG), ou seja, idas ao serviço de urgência ou internamento por complicações de EoE ou histologia grave (HistG), biópsia com Eo > 50 e/ou microabcessos. Resultados: 74 pacientes (81% sexo masculino, média de idades 27±17 anos), 36 Cr e 38 Ad. Os sintomas mais frequentemente reportados foram, no grupo Cr disfagia (73%) e refluxo gastroesofágico (46%), enquanto no grupo Ad impactação (85%) e disfagia (56%). Foram referidos antecedentes de atopia em 96% das Cr, e 67% dos Ad. Em 77% das Cr e 69% dos Ad havia sensibilização alimentar. Os achados endoscópicos mais frequentes no grupo Cr foram estriação (65%) e placas brancas (50%), enquanto que no grupo Ad foram placas brancas (42%) e anéis esofágicos (35%). HistG (46%) associou-se a ClinG (35%), p = 0,001, nas Cr, mas o mesmo não foi objetivado no grupo Ad [ClinG (22%) e HistG (17%), p = 0,5]. Conclusão: Os nossos resultados estão de acordo com o descrito na literatura, observando-se um predomínio do sexo masculino e uma maior frequência de história de atopia e sensibilização alimentar no grupo Cr. As situações graves de impactação e estenose esofágica foram mais frequentes nos Ad, e objetivou-se uma associação de histologia grave com clínica grave, apenas nas Cr.

Background: Eosinophilic esophagitis (EoE) is an immunologically mediated chronic inflammatory disease of the esophagus characterized by symptoms related to esophageal dysfunction and eosinophilic infiltration in the esophageal mucosa. This study aimed to characterize patients with a diagnosis of EoE and analyze differences between patients with EoE diagnosed at pediatric age (Ch, <18 years) and at adult age (Ad, ≥18 years). Methods: This was a retrospective study of patients with a diagnosis of EoE who were followed in the immunoallergology department from February 2009 to July 2017. Patients were divided into Ch and Ad groups and characterized according to demographic data, history of atopy, symptoms, food sensitization, total IgE, eosinophils (Eo), upper digestive endoscopy (UDE) findings, and biopsy findings. Correlations were assessed between food sensitization, clinical severity (SClin; determined by number of ER visits or hospital admissions for EoE complications), and severe histology (SHist; defined as biopsy with Eo >50 and/or microabscesses). Results: 74 patients (81% male, mean age 27±17 years), 36 Ch and 38 Ad. The most commonly reported symptoms were dysphagia (73%) and gastroesophageal reflux (46%) in the Ch group, and impaction (85%) and dysphagia (56%) in the Ad group. History of atopy was reported in 96% of Ch vs 67% of Ad. Food sensitization was found in 77% of Ch vs 69% of Ad. The most common UDE findings were striation (65%) and white plaques (50%) in the Ch group, and white plaques (42%) and esophageal rings (35%) in the Ad group. SHist (46%) was associated with SClin (35%) in Ch (p=0.001), but not in Ad (SClin [22%] and SHist [17%], p=0.5). Conclusion: Our results are consistent with those reported in the literature, with a male predominance and a higher prevalence of atopy and food sensitization in Ch. Severe impaction and esophageal stenosis were more frequent in Ad, but an association between SHist and SClin was found only in Ch.
