ABSTRACT
La esofagitis eosinofílica (EoE) es una enfermedad causada por una respuesta inmune frente a antígenos alimentarios en contacto con la mucosa esofágica; por su parte, la enfermedad de Von Willebrand (EVW) es el trastorno hemorrágico hereditario más común en los seres humanos. La característica central de todos los tipos de EVW, es la presencia de cantidades reducidas o de formas anormales del factor de Von Willebrand (FVW) en el torrente sanguíneo. Debido a que no se han reportado casos previos de EVW tipo 2A asociada a EoE, se describe este caso clínico con el objetivo principal de dar a conocer el hallazgo casual de estas dos patologías, la seguridad de la evaluación por endoscopia de vías digestivas altas y el pronóstico de posibles complicaciones
Eosinophilic esophagitis (EoE) is a disease caused by an immune response against food antigens in contact with the esophageal mucosa; alternatively, Von Willebrand disease (VWD) is the most common inherited bleeding disorder in humans. The central characteristic of all types of VWD is the presence of reduced amounts or abnormal forms of VWF in the bloodstream. Since no previous cases of VWD type 2A associated to EoE have been reported, this clinical case is described with the main objective to present the coincidental finding of these two pathologies, the safety of the evaluation by upper gastrointestinal endoscopy, and the prognosis of possible complications

Zenker's diverticulum develops in the hypopharynx, usually between the cricopharyngeus muscle and the inferior pharyngeal constrictor muscle, at the level of the C5 and C6 vertebrae. It often manifests clinically with dysphagia, persistent reflux, and halitosis. Its reference diagnosis is through barium video swallowing observed by fluoroscopy. Management is surgical with a cervical or transoral approach, the latter having a better safety profile

Resumen Objetivo: Describir resultados de la cirugía de sustitución esofágica con tubo gástrico invertido, vía ascenso retroesternal en dos hospitales pediátricos durante el período marzo 2015 a marzo 2018. Materiales y Método: Un estudio observacional, transversal, con recolección de datos retrospectivo, donde se incluyeron todos los expedientes de pacientes que presentaban patología del esófago por causa adquirida o congénita que fueron operados de sustitución esofágica con tubo gástrico invertido en dos hospitales pediátricos durante 3 años. Resultados: Encontramos 29 niños sometidos a sustitución esofágica, de los cuales 27 cumplieron criterios de inclusión. La edad comprendida entre 2 y 17 años. El 63% corresponde al sexo femenino. La causa más frecuente de sustitución esofágica es por estenosis esofágica por ingesta caustica (92,59%). El 70% presentó algún tipo de complicación luego de la cirugía. La fístula esofagocutánea es la complicación principal con 33,33%. La permanencia en la unidad de cuidados intensivos es menor de 24 horas en un 74% de los niños. Se inicia la vía oral en casi la mitad de casos entre los 10-12 días de posquirúrgico, la estancia hospitalaria es en promedio 18,5 días. La mortalidad es 3,7%. Conclusión: La sustitución esofágica por tubo gástrico invertido vía ascenso retroesternal, es una técnica comparable en resultados a la interposición de colón. Para los autores, el estómago es un órgano ideal para realizar la reconstrucción esofágica, y sus complicaciones son manejables.
Aim: To describe the results of esophageal replacement surgery with an inverted gastric tube via retrosternal ascent in two pediatric hospitals during the period March 2015 to March 2018. Materials and Method: an observational, cross-sectional study with retrospective data collection that included all the records of patients with esophageal discontinuity due to acquired or congenital causes who underwent esophageal replacement surgery with an inverted gastric tube in two pediatric hospitals for 3 years. Results: We found 29 children undergoing esophageal replacement, of which 27 met inclusion criteria. The age between 2 to 17 years. 63% corresponds to the female sex. The most frequent cause of esophageal replacement is esophageal stricture due to caustic ingestion (92.59%). 70% presented some type of complication after surgery. The esophagocutaneous fistula is the main complication with 33.33%. The stay in the intensive care unit is less than 24 hours in 74% of children. The oral route is started in almost half of cases between 10-12 days after surgery; the hospital stay is on average 18.5 days. Mortality is 3.70%. Conclusión: The esophageal substitution by inverted gastric tube via retrosternal ascent is a technique comparable in results to the interposition of the colon. For the authors, the stomach is an ideal organ to perform esophageal reconstruction, and its complications are manageable.

Abstract A report of two cases of esophageal intramural pseudodiverticulosis, a very unusual disease, with other 240 cases reported in the entire world literature since 1960. Its etiology and pathogenesis are still not fully understood. However, it is believed that hypertrophy of the submucosal glands, with chronic inflammation, fibrosis, and consequent esophageal stenosis, causes dysphagia, which is the primary manifestation of esophageal intramural pseudodiverticulosis. The main diagnostic methods include the radiological examination of the esophagus with barium contrast (esophagogram) and esophagogastroduodenoscopy (EGD). Both reported cases were treated with endoscopic dilation, exemplifying the safety and efficacy of this therapeutic option for treating dysphagia in these individuals.
Resumen Reporte de dos casos de pseudodiverticulosis esofágica intramural, una enfermedad muy inusual, con otros 240 casos reportados en toda la literatura mundial desde 1960. Su etiología y patogenia aún no se conocen completamente; sin embargo, se cree que existe una hipertrofia de las glándulas submucosas, con inflamación crónica, fibrosis y consecuente estenosis esofágica, lo que provoca disfagia, que es la principal manifestación de la pseudodiverticulosis esofágica intramural. El examen radiológico del esófago con contraste de bario (esofagograma) y la endoscopia digestiva alta (EDA) son los principales métodos de diagnóstico. Ambos casos reportados se trataron con dilatación endoscópica, lo que ejemplifica la seguridad y eficacia de dicha opción terapéutica para el tratamiento de la disfagia en estos individuos.

Abstract This study aimed to analyze the role of period, geographic and socio demographic factors in cancer-related mortality by prostate, breast, cervix, colon, lung and esophagus cancer in Brazilians capitals (2000-2015). Ecological study using data of Brazilian Mortality Information. Multilevel Poisson models were used to estimate the adjusted risk of cancer mortality. Mortality rate levels were higher in males for colon, lung and esophageal cancers. Mortality rates were highest in the older. Our results showed an increased risk of colon cancer mortality in both sexes from 2000 to 2015, which was also evidenced for breast and lung cancers in women. In both genders, the highest mortality risk for lung and esophageal cancers was observed in Southern capitals. Midwestern, Southern and Southeastern capitals showed the highest mortality risk for colon cancer both for males and females. Colon cancer mortality rate increased for both genders, while breast and lung cancers mortality increased only for women. The North region showed the lowest mortality rate for breast, cervical, colon and esophageal cancers. The Midwest and Northeast regions showed the highest mortality rates for prostate cancer.
Resumo Este estudo teve como objetivo analisar o papel de fatores temporais, geográficos e sociodemográficos na mortalidade por câncer de próstata, mama, colo do útero, cólon, pulmão e esôfago nas capitais brasileiras (2000-2015). Estudo ecológico utilizando informações brasileiras de mortalidade. Modelos de Poisson multinível foram usados para estimar o risco ajustado de mortalidade por câncer. Os níveis de mortalidade foram maiores em homens para câncer de cólon, pulmão e esôfago. As taxas de mortalidade foram mais altas nos idosos. Nossos resultados mostraram risco aumentado de mortalidade por câncer de cólon em ambos os sexos de 2000 a 2015, o que também foi evidenciado para câncer de mama e de pulmão em mulheres. Em ambos os sexos, o maior risco de mortalidade para câncer de pulmão e esôfago foi observado nas capitais do Sul. As capitais do Centro-Oeste, Sul e Sudeste apresentaram o maior risco de mortalidade por câncer de cólon tanto para homens quanto para mulheres. A taxa de mortalidade por câncer de cólon aumentou para ambos os sexos, enquanto a mortalidade por câncer de mama e de pulmão aumentou apenas para as mulheres. A região Norte apresentou a menor taxa de mortalidade por câncer de mama, colo do útero, cólon e esôfago. As regiões Centro-Oeste e Nordeste apresentaram as maiores taxas de mortalidade por câncer de próstata.

Introducción: el pénfigo vulgar comprende un grupo de enfermedades heterogéneas autoinmunes ampollosas de la piel y las mucosas. La afectación esofágica en el pénfigo vulgar es rara, con una prevalencia incierta que requiere un abordaje diagnóstico y terapéutico detallado. Caso clínico: mujer de 37 años, con antecedentes de tratamiento con inhibidores de la Cox-2 debido a hernia discal. Se envió a Gastroenterología por pérdida de peso de aprox. 5kg en un mes. La paciente tuvo presencia de disfagia, odinofagia y dolor retroesternal con pobre tolerancia a la vía oral. Se hizo endoscopía que reportó esofagitis disecante superficial y gastropatía eritematosa de antro; el duodeno estaba en estado normal. Los hallazgos se correlacionaron con el diagnóstico de pénfigo vulgar con afectación exclusiva a esófago. En la valoración no se identificaron lesiones en piel, cavidad oral u otras mucosas. Se hizo nueva endoscopía como control y se encontró inmunofluorescencia de biopsia esofágica reactiva a IgG 2. Se dio manejo inicial con glucocorticoides, antiinflamatorios e inmunosupresores. Conclusiones: la importancia del estudio del pénfigo radica no solo en la alta morbimortalidad asociada, sino en lo raro y complejo de su detección, pues los pacientes suelen tardar varios meses en tener un diagnóstico certero y aún más en conseguir las metas terapéuticas. Es prioritaria la difusión del estudio del pénfigo entre los profesionales de lasalud involucrados en su detección.
Background: Pemphigus vulgaris comprises a group of heterogeneous blistering autoimmune diseases of the skin and mucosa. Esophageal involvement within pemphigus vulgaris is rare with an uncertain prevalence that requires a detailed diagnostic and a therapeutic approach. Clinical case: 37-year-old female, with a history of treatment with Cox-2 inhibitors due to herniated disc. She is sent to the Gastroenterology Service for weight loss of approximately 5 kilos in a month, with the presence of dysphagia, odynophagia and retrosternal pain with poor toleranceto the oral route. Endoscopy was performed, which reported esophagitis dissecans superficialis (EDS), erythematous gastropathy of the antrum and normal duodenum. Findings were correlated with the diagnosis ofpemphigus vulgaris with exclusive involvement of the esophagus. The evaluation did not identify lesions on the skin, oral cavity or other mucous membranes. A new endoscopy was performed as a control and it was found immunofluorescence of the esophageal biopsy reactive to IgG 2. Initial management was given with glucocorticoids, anti-inflammatories and immunosuppressants. Conclusions: The importance of the study ofpemphigus lies not only in the high associated morbidity and mortality, but also in its intrinsic rarity and the complexity of its detection, given that patients usually take several months to have an accurate diagnosis and even more time to achieve therapeutic goals. It is a priority the dissemination of the study of pemphigus among health professionals involved in its detection.

Abstract Accidental fish bone ingestion is a common complaint at emergency departments. The majority of cases have a benign course. However, serious complications such as esophagus perforation, cervical vessel injury and cervical abscess can occur in 7.4% of cases. Mortality rates can be as high as 50% when mediastinitis occurs. We report a case of an esophageal perforation caused by a fish bone with a lesion to the right common carotid artery after 20 days of evolution. Surgical exploration occurred with corrections of the lesion in the right common carotid and esophagus. Early identification of this kind of injury is paramount to prevent potentially fatal complications.

Introducción: la heterotopia de mucosa gástrica del esófago proximal (HMGEP) es una entidad clínica poco entendida y probablemente subdiagnosticada, que consiste en la presencia de islas de mucosa gástrica ectópica en el esófago proximal. Caso clínico: presentamos el caso de un neonato que presenta de manera temprana estridor y distrés respiratorio secundario a mucosa redundante en la región poscricoidea, que prolapsa sobre la supraglotis y ocluye la luz de la vía aérea. El estudio histopatológico reporta HMGEP. Se realiza una terapia ablativa con láser, con lo cual la paciente se recupera paulatinamente. Metodología: se llevó a cabo una amplia búsqueda de la literatura de HMGEP en las bases de datos PubMed, SciELO, Mendeley y Elsevier, en idioma inglés y español, desde 1980 a 2021 y se incluyeron 18 artículos en total. Discusión: la HMGEP suele ser una entidad asintomática que en ocasiones genera síntomas faringolaríngeos, y de manera infrecuente puede asociarse con complicaciones como estenosis, úlceras, perforación esofágica e incluso obstrucción de la vía aérea como en el presente caso. Conclusiones: además de las diversas alteraciones en la vía aérea que pueden generar estridor y dificultad respiratoria en niños, debemos descartar causas gastroesofágicas subyacentes asociadas con estas manifestaciones, como la HMGEP.logos y expertos en radioterapia permite obtener buenos resultados quirúrgicos y clínicos en la inmensa mayoría de casos.
Introduction: Gastric mucosal heterotopia of the proximal esophagus (HMGEP) is a poorly understood and probably underdiagnosed clinical entity that consists of the presence of islands of ectopic gastric mucosa in the proximal esophagus. Clinical Case: In this article, we present the case of a newborn who started with early stridor and respiratory distress secondary to redundant mucosa in the postcricoid region that prolapsed over the supraglottis, occluding the airway lumen. The histopathological study reports HMGEP. Ablative laser therapy is performed with which the patient gradually recovers. Methodology: An extensive search of the HMGEP literature was conducted in PubMed, SciELO, Mendeley, and Elsevier data base; in English and Spanish, from 1980 to 2021, including a total of 18 articles. Discussion: HMGEP is usually an asymptomatic entity that sometimes causes pharyngolaryngeal symptoms and, infrequently, can be associated with complications such as stenosis, ulcers, esophageal perforation, and even airway obstruction, as in the present case. Conclusions: In addition to the various alterations in the airway that can generate stridor and respiratory distress in children, we must rule out underlying gastroesophageal causes associated with these manifestations, such as HMGEP.

Introducción. El divertículo de Zenker es una evaginación sacular ciega que puede presentarse a nivel faringoesofágico. No se conoce exactamente su incidencia en la edad pediátrica, constituyendo una patología muy infrecuente. La sintomatología es inespecífica, lo que dificulta el diagnóstico precoz y determina un mayor riesgo de complicaciones asociadas. Caso clínico. Paciente preescolar femenina con cuadro recurrente de emesis con deshidratación, posteriormente asociado a disfagia, a quien se le diagnosticó un divertículo de Zenker. Se realizó tratamiento quirúrgico con hallazgo intraoperatorio de dilatación esofágica, un área de estenosis secundaria al hallazgo incidental de un cuerpo extraño y divertículo de Zenker en la región lateral del esófago dilatado. Discusión. Esta patología es extremadamente rara, pero se debe tener en cuenta dentro de los diagnósticos diferenciales en pacientes con sintomatología faringo-esofágica. Conclusión. Se presenta una preescolar sin antecedente de procedimientos esofágicos o malformaciones congénitas asociadas con diagnóstico de un divertículo de Zenker y dilatación esofágica por un cuerpo extraño, tratada quirúrgicamente de forma exitosa.
Introduction. Zenker's diverticulum is a blind saccular evagination that can present at the pharyngoesophageal level. Its incidence in pediatric age is not exactly known, constituting a very infrequent pathology. The symptoms are nonspecific, which makes early diagnosis difficult and determines a higher risk of associated complications.Clinical case. Female preschool patient with recurrent dehydration due to emesis, later associated with dysphagia, who was diagnosed with Zenker's diverticulum. Surgical treatment was performed with intraoperative finding of esophageal dilation, an area of stenosis secondary to the incidental finding of a foreign body, and a Zenker's diverticulum in the lateral region of the dilated esophagus. Discussion. This pathology is extremely rare, but it should be taken into account within the differential diagnoses in patients with pharyngo-esophageal symptoms. Conclusion: We present a preschool female patient with no history of esophageal procedures or congenital malformations associated with a diagnosis of Zenker's diverticulum and esophageal dilation due to a foreign body, successfully treated surgically.

RESUMEN: El pudú (Pudu puda), pertenece al orden Artiodactyla y a la familia Cervidae, corresponde al segundo cérvido más pequeño del mundo y es endémico de Chile y Argentina. Son herbívoros que se alimentan de hojas jóvenes y brotes de algunos árboles, arbustos, hierbas, frutos y flores. Esta especie está catalogada en estado Vulnerable, por lo que se prohíbe su caza y captura, esto debido a que su población ha disminuido sustancialmente a causa de la pérdida y fragmentación de la vegetación nativa, los incendios forestales, ataques de perros asilvestrados y caza furtiva. Existe escasa información científica anatómica de esta especie, y más aún referente a su morfología digestiva, por lo que se requieren estudios que aporten información específica de este cérvido. Se utilizaron dos cadáveres de pudú hembras adultas, los cuales fueron donados por el Servicio Agrícola y Ganadero (SAG) de Talca, Región del Maule, Chile. Dentro de los resultados, podemos indicar que la cavidad oral, glándulas salivares y esófago se asemejan a otros rumiantes domésticos, como también existen semejanzas con el venado de campo, sin embargo, existen diferencias como la forma y desarrollo de la glándula parótida; el conducto parotídeo pasa ventral al músculo masetero y se abre en una papila a nivel del tercer premolar superior; la glándula mandibular se divide en tres lobos; la glándula sublingual solo posee porción polistomática, las glándulas bucales dorsales poseen un menor tamaño que las bucales ventrales, la glándula bucal ventral es alargada y de forma compacta y se observa la presencia de una redondeada glándula bucal intermedia, poseen 11 crestas palatinas por lado en el paladar duro y además la papila incisiva se encuentra rodeando al pulvino dental. Esta información es relevante y corresponde a un aporte al conocimiento específico de esta especie, la cual es endémica, vulnerable y protegida.
SUMMARY: The pudu (Pudu puda), belongs to the Artiodactyla order and the Cervidae family, corresponding to the second smallest deer in the world and is endemic to Chile and Argentina. They are herbivores that feed on young leaves and shoots of certain trees, shrubs, herbs, fruits, and flowers. The status of is species is classified as Vulnerable; therefore, its hunting and capture is prohibited, this because its population has decreased substantially due to the loss and fragmentation of native vegetation, forest fires, attacks by feral dogs and poaching. There is little scientific anatomical information available on this species, and even more so regarding its digestive morphology, which is why studies are required to provide specific information on this deer. Two adult female pudu specimens were used, which were donated by the Agricultural and Livestock Service (SAG) of Talca, Maule Region, Chile. Among the results, we can indicate that the oral cavity, salivary glands and esophagus resemble other domestic ruminants; there are also similarities with the field deer, however, there are differences such as the shape and development of the parotid gland; the parotid duct passes ventral to the masseter muscle and opens into a papilla at the level of the upper third premolar; the mandibular gland is divided into three wolves; the sublingual gland only has a polystomatic portion, the dorsal buccal glands are smaller than the ventral buccal glands, the ventral buccal gland is elongated and compact and the presence of a rounded intermediate buccal gland is observed, it has 11 palatal ridges per side in the hard palate and also the incisive papilla is found surrounding the dental pulvino. This information is relevant and corresponds to a report on the specific knowledge of this species, which is endemic, vulnerable, and protected.

RESUMEN: Tradicionalmente, la Histología se ha apoyado del análisis de preparaciones histológicas a través del microscopio para su enseñanza. En este sentido, uno de los principales obstáculos que enfrentan los estudiantes al analizar los tejidos, es extrapolar una imagen bidimensional a una estructura tridimensional (3D). La impresión 3D permite subsanar esta limitación, haciendo posible fabricar material docente, con las características requeridas con un alto grado de detalle y bajo costo. El objetivo de este trabajo fue diseñar y fabricar modelos impresos en 3D como complemento para las clases prácticas de Histología Médica. Se fabricaron modelos impresos en 3D de la ultraestructura de la barrera de filtración glomerular (BFG) en su estado normal y síndrome nefrótico. Además, se fabricó un modelo de la capa muscular del esófago humano dando énfasis a la disposición helicoidal de sus fibras musculares. Los modelos de epidermis permitieron identificar sus distintos estratos: estrato córneo, estrato granuloso, estrato espinoso, y estrato basal. Dentro los beneficios derivados de la impresión de modelos en 3D podemos destacar el bajo costo económico de su fabricación, alta reproducibilidad, bioseguridad, y potencial para favorecer el aprendizaje y la enseñanza de la Histología. No obstante, es necesario analizar la percepción y beneficio sobre el aprendizaje de los estudiantes derivados de la aplicación de los modelos mediante técnicas de evaluación cuantitativas y cualitativas.
SUMMARY: Traditionally, Histology has relied on the analysis of histological slides through the microscope for its teaching. In this sense, one of the main obstacles faced by students when analyzing tissues is to extrapolate a two-dimensional image to a three-dimensional (3D) structure. 3D printing makes it possible to overcome this limitation, making it possible to manufacture teaching material with the required characteristics with a high degree of detail and low cost. The objective of this work was to design and manufacture 3D printed models as a complement for the practical classes of Medical Histology. 3D printed models of the ultrastructure of the glomerular filtration barrier (GFB) in its normal state and nephrotic syndrome were fabricated. In addition, a model of the muscular layer of the human esophagus was fabricated emphasizing the helical arrangement of its muscle fibers. The epidermis models allowed the identification of its different layers: stratum corneum, stratum granulosum, stratum spinosum, and stratum basale. Among the benefits derived from 3D printing of models, we can highlight the low economic cost of manufacturing, biosafety and potential to favor the learning and teaching of Histology. However, it is necessary to analyze the perception and benefit on student learning derived from the application of the models by means of quantitative and qualitative evaluation techniques.

Resumen La hemorragia digestiva alta (HDA) es una emergencia médico-quirúrgica común que debe ser tratada precozmente por su alta morbimortalidad. Corresponde a sangrado del esófago, estómago o del duodeno proximal, y se divide en etiología no variceal y variceal. Dentro de las no variceales destaca la úlcera péptica como la más frecuente, siendo esta producida por un desbalance entre factores protectores y agresivos. Por otro lado, en las hemorragias variceales destacan las várices gastroduodenales, las cuales son consecuencia del aumento de la presión portal. La incidencia de la HDA a nivel mundial varía entre 37 a 172 casos por cada 100.000 habitantes por año y la mortalidad entre un 5 y un 14% según diferentes estudios. Lamentablemente, no existen cifras nacionales fidedignas de incidencia y prevalencia. El médico debe conocer bien la presentación clínica y la fisiopatología para ser asertivo en la sospecha, diagnóstico y manejo de esta patología. En cuanto al tratamiento, el enfrentamiento se divide en el manejo de urgencias y luego endoscópico, puesto que la resucitación temprana intensiva puede reducir la morbimortalidad en pacientes con HDA. A continuación se hará una revisión actualizada enfocada en los aspectos más relevantes del manejo de esta patología. Se obtuvieron los datos de Pubmed y Scielo, específicamente la búsqueda de artículos originales y de revisiones sistemáticas con las palabras "hemorragia digestiva alta", "úlcera péptica", "várices esofágicas" y otras relacionadas. Los criterios usados fueron artículos preferentemente menores a 5 años de publicación en revistas científicas de alto índice de impacto.
Upper gastrointestinal bleeding (UHD) is a common medical-surgical emergency that must be treated early due to its high morbidity and mortality. It corresponds to bleeding from the esophagus, stomach, or proximal duodenum, and is divided into non-variceal and variceal etiology. Among the non-variceal, the peptic ulcer stands out as the most frequent, being this produced by an imbalance between protective and aggressive factors. On the other hand, in variceal hemorrhages gastroduodenal varices stand out, are a consequence of increased portal pressure. The incidence of HDA worldwide varies between 37 to 172 cases per 100,000 inhabitants per year and mortality between 5 to 14% according to different studies. Unfortunately, there are no reliable national statistics of incidence and prevalence. The physician must have a good understanding of the clinical presentation and pathophysiology to be assertive in the suspicion, diagnosis, and management of this pathology. Regarding treatment, the confrontation is divided into emergency management and then endoscopic, because early intensive resuscitation can reduce morbidity and mortality in patients with UHD. This is an updated review which will be focused on the most relevant aspects of the management of this pathology. Data were obtained from Pubmed and Scielo, specifically searching for original articles and systematic reviews with the words "upper gastrointestinal bleeding", "peptic ulcer", "esophageal varices" and other related words. The criteria used were articles preferably less than 5 years old in scientific journals with a high impact index.

Resumen El dolor torácico es un motivo de consulta muy frecuente en el servicio de urgencias. El abordaje adecuado del paciente en el que se incluye el diligenciamiento de la historia clínica, el examen físico y la toma de paraclínicos iniciales son cruciales para determinar cuáles son los posibles diagnósticos diferenciales. A continuación, presentamos el caso de un paciente de 71 años que ingresa al servicio de urgencias por un dolor retroesternal intenso posterior al consumo de alimentos, en quien, ante la persistencia del dolor, biomarcadores cardíacos negativos y patología aórtica descartada, se realiza una endoscopia que evidencia un hematoma disecante del esófago. En general, el pronóstico es bueno, pero es de gran importancia una buena historia clínica para su sospecha.
Abstract Chest pain is a very common reason for consultation in the emergency department. An adequate approach to the patient, including medical history, physical examination and initial laboratory tests, is crucial for determining possible differential diagnoses. The following is the case of a 71-year-old patient that visited the emergency room due to severe retrosternal pain after food consumption. In view of the persistence of pain and negative cardiac biomarkers, and after ruling out aortic disease, the patient underwent an endoscopy that showed dissecting hematoma of the esophagus. The prognosis is generally favorable, but a thorough medical history is required to suspect it.

The Muscovy duck is a commercially important bird on the island of Marajó usually raised in a peculiar system that includes supplying fish viscera to the birds under semi-extensive farming conditions. This enables a risk of contamination and losses in the production of these birds, resulting from injuries caused by helminth infections, especially nematodes. The objective of this study was to evaluate the histopathological changes caused by nematodes of the genera: Eucoleus, Anisakis and Contracaecum. Thirty-three ducks with lesions in the esophagus and ventricle were analyzed. Histopathological exams showed a mild inflammatory infiltrate in the submucosa of the esophagus caused by the fixation of E. contortus and third stage larvae of Anisakis sp., and we recorded third stage larvae of Contracaecum sp. parasitizing the ventricle, this being the first record of this parasite in ducks in Brazil.(AU)
O pato doméstico é uma ave amplamente comercializada na Ilha de Marajó, com um peculiar manejo que inclui a oferta de vísceras de peixes aos animais em criações semiextensivas, propiciando, assim, risco de contaminação e perdas na produção dessas aves decorrentes de lesões oriundas de infecções por helmintos, especialmente os nematódeos. Nesse sentido, objetivou-se avaliar as alterações histopatológicas causadas por nematódeos dos gêneros: Eucoleus, Anisakis e Contracaecum. Foram analisados 33 patos, e três exemplares apresentaram lesões no esôfago e no ventrículo. Exames histopatológicos demonstraram discreto infiltrado inflamatório na submucosa do esôfago ocasionado pela fixação de E. contortus e larvas de terceiro estágio de Anisakis sp., bem como foram registradas larvas de terceiro estágio de Contracaecum sp. parasitando o ventrículo, sendo esse o primeiro registro desse parasito em patos no Brasil.(AU)

Resumen Mediante la distensión de un balón con líquido conductor, la sonda de imagen luminal funcional endoluminal (EndoFLIP) evalúa las propiedades biomecánicas como la distensibilidad, volumen, presión e inclusive diámetros de regiones esfinterianas como la unión gastroesofágica, píloro y ano. La mayor evidencia en la utilidad clínica de la EndoFLIP está en los trastornos de motilidad esofágica, principalmente para identificar acalasia cuando la manometría esofágica de alta resolución y otras imágenes no logran diagnosticarla e inclusive, mediante el programa de FLIP 2.0, caracteriza la acalasia en subtipos a partir de patrones de motilidad del esófago distal en respuesta a la distensión. Se ha demostrado recientemente que la EndoFLIP tiene un rol diagnóstico, pronóstico o terapéutico en otras patologías como la esofagitis eosinofílica, reflujo gastroesofágico, gastroparesia, durante la fundoplicatura y dilatación esofágica.
Abstract EndoFLIP evaluates biomechanical properties such as distensibility, volume, pressure, and even diameters of sphincter regions like the gastroesophageal junction, pylorus, and anus, by distending a balloon with a conductive medium. The best evidence of the clinical utility of EndoFLIP is observed in esophageal motility disorders, mainly when identifying achalasia when high-resolution esophageal manometry and other images fail to diagnose it. Even EndoFLIP 2.0 characterizes achalasia into subtypes based on distal esophageal motility patterns in response to distention. Recently, it has been shown that this system has a diagnostic, prognostic and/or therapeutic role in other diseases such as eosinophilic esophagitis, gastroesophageal reflux, and gastroparesis, and during fundoplication and esophageal dilation.

Resumen La lengua negra pilosa (LNP) es una alteración benigna caracterizada por coloración oscura e hipertrofia con hiperqueratosis en las papilas filiformes de la superficie de la lengua. Han sido implicados varios factores intrínsecos y extrínsecos como causales, entre ellos la pobre higiene dental, el tabaquismo, la ingesta de bebidas oscuras, el uso de antibióticos y algunas patologías malignas. Reportamos el caso de un paciente con carcinoma escamocelular avanzado de esófago medio conjunto con LNP, asociación no encontrada previamente en la literatura.
Abstract Black hairy tongue (BHT) is a benign disorder characterized by dark coloration and hypertrophy with hyperkeratosis in filiform papillae on the surface of the tongue. Several intrinsic and extrinsic factors, including poor dental hygiene, smoking, drinking dark beverages, indiscriminate use of antibiotics, and some malignant diseases, have been proposed as potential causes. This is the case of a patient with advanced squamous cell carcinoma of the mid esophagus in conjunction with BHT, a previously unknown association.

Resumen Introducción: Los adenomas vellosos son lesiones del tubo digestivo con tendencia alta a la malignidad. Su ubicación en parches de mucosa gástrica ectópica en el esófago cervical determina una presentación atípica de interés tanto clínico como patológico. Objetivo: Presentar un caso de adenoma velloso en la mucosa gástrica ectópica del esófago cervical. Métodos: Describir el caso de un paciente con diagnóstico de adenoma velloso y realizar una revisión de la literatura disponible hasta el momento. Resultados: Se identificó mediante un estudio histopatológico un adenoma tubulovelloso con displasia de bajo grado, cuya ubicación endoscópica era un parche de mucosa ectópica gástrica en el esófago cervical. Conclusiones: La ubicación de los adenomas vellosos en el esófago cervical puede predisponer al desarrollo de lesiones neoplásicas. La evaluación detallada de este segmento, con técnicas como la cromoendoscopia digital de alta definición, permiten la detección temprana de estas lesiones y su oportuna intervención.
Abstract Introduction: Villous adenomas are lesions of the digestive tract with a high tendency to malignancy. Its location in ectopic gastric mucosa patches in the cervical esophagus is an atypical presentation of clinical and pathological interest. Objective: To present a case of villous adenoma in ectopic gastric mucosa of the cervical esophagus. Methods: A case study of a patient with a diagnosis of villous adenoma is presented, as well as a review of the current literature. Results: A tubulovillous adenoma with low-grade dysplasia was identified by histopathological study. Its endoscopic location was a gastric ectopic mucosa patch in the cervical esophagus. Conclusions: The location of villous adenomas in the cervical esophagus may predispose to the development of neoplastic lesions. Detailed evaluation of this segment using techniques, such as high-definition digital chromoendoscopy, would allow for early detection and treatment of these lesions.

Objective: To investigate the safety and feasibility of laparoscopic double-flap technique (Kamikawa) in digestive tract reconstruction after proximal gastrectomy for esophagogastric junction (EGJ) leiomyoma and gastrointestinal stromal tumor (GIST) with the maximum diameter >5 cm. Methods: A descriptive case-series study was used to retrospectively analyze the data of patients with EGJ leiomyoma and GIST undergoing laparoscopic-assisted proximal gastrectomy and double-flap technique (Kamikawa) at the Department of Gastrointestinal Surgery, Guangdong Hospital of Traditional Chinese Medicine from September 2017 to March 2019. All the tumors invaded the cardia dentate line, and the maximum diameter was >5 cm. After the exclusion of patients requiring emergency surgery and complicating with severe cardiopulmonary diseases, a total of 4 patients, including 3 males and 1 female with age of 29-49 years, were included in this study. After laparoscopic-assisted proximal gastrectomy, the residual stomach was pulled out of the abdominal cavity and marked with methylene blue at the proximal end 3~4 cm from the anterior wall of the residual stomach in the shape of "H". The gastric wall plasma muscular layer was cut along the "H" shape, and the space between the submucosa and the muscular layer was separated to both sides along the longitudinal incision line to make the seromuscular flap. The residual stomach was put back into the abdominal cavity. Under laparoscopy, 4 stitches were intermittently sutured at the upside of "H" shape and 4-5 cm from the posterior wall of the esophageal stump. The stump of the esophagus was cut open, and the submucosa and mucosa were cut under the "H" shape to enter the gastric cavity. The posterior wall of the esophageal stump was sutured continuously with the gastric stump mucosa and submucosa under laparoscopy. The anterior wall of the esophageal stump was sutured continuously with the whole layer of the residual stomach. The anterior wall of the stomach was sutured to cover the esophagus. The anterior gastric muscle flap was sutured and embedded in the esophagus to complete the reconstruction of digestive tract. The morbidity of intraoperative complications and postoperative reflux esophagitis and anastomosis-related complications were observed. Results: All the 4 patients completed the operation successfully, and there was no conversion to laparotomy. The median operative time was 239 (192-261) minutes, the median Kamikawa anastomosis time was 149 (102-163) minutes, and the median intraoperative blood loss was 35 (20-200) ml. The abdominal drainage tube and gastric tube were removed, and the fluid diet was resumed on the first day after surgery in all the 4 patients. The median postoperative hospitalization time was 6 (6-8) days. Postoperative pathology revealed 3 leiomyomas and 1 GIST. There were no postoperative complications such as anastomotic leakage or stenosis, and no reflux symptoms were observed. The median follow-up time was 22 (11-29) months after the operation, and no reflux esophagitis occurred in any of the 4 patients by gastroscopy. Conclusion: For >5 cm EGJ leiomyoma or GIST, double-flap technique (Kamikawa) used for digestive tract reconstruction after proximal gastrectomy is safe and feasible.

Resumen La endosonografía es un método diagnóstico que viene revolucionando el abordaje de los pacientes con tumores del tracto gastrointestinal y de otros órganos y estructuras extradigestivas. En la actualidad, se viene posicionando como un método de elección en la evaluación de lesiones subepiteliales gastrointestinales y en la estadificación de muchos tumores gastrointestinales como de esófago, estómago, recto y páncreas. Por lo anterior pretendemos hacer una revisión de tema mostrando la evidencia de la endosonografía en indicaciones clásicas y aplicaciones actuales en tumores gastrointestinales.
Abstract Endosonography is a diagnostic method that has revolutionized the way to approach patients with tumors in the gastrointestinal tract and other extra-digestive organs and structures. Currently, it is a method of choice to assess subepithelial lesions of the gastrointestinal tract and to classify gastrointestinal tumors in the esophagus, stomach, rectum, and pancreas. Therefore, this literature review presents evidence on the classical indications of endosonography, as well as current applications to approach gastrointestinal tumors.
