RESUMEN
Small-bowel bleeding is a relatively uncommon event of gastrointestinal bleeding. Some causes of small-bowel bleeding, such as vascular lesions, are still challenging to confirm, despite the use of various diagnostic modalities (e.g., capsule endoscopy, deep enteroscopy, and radiographic imaging). Vascular lesion-induced bleeding tends to be insidious and intermittent, but sometimes it can be massive and fatal, so that the timing of an endoscopy is critical. We describe herein the case of an elderly female patient with Dieulafoy's lesion-induced small-bowel bleeding presenting with recurrent melena. In this article, we describe how the cause of her bleeding was found and how the bleeding was stopped endoscopically. Finally, we discuss the characteristics of a small-bowel Dieulafoy's lesion and its endoscopic treatment.

O mieloma múltiplo é uma neoplasia progressiva e incurável de células B, caracterizado pela proliferação desregulada e clonal de plasmócitos na medula óssea. A síndrome de hiperviscosidade é uma das complicações relacionadas às gamopatias monoclonais, sendo considerada emergência oncológica. O objetivo deste estudo foi descrever o quadro clínico de um paciente diagnosticado com mieloma múltiplo que apresentou síndrome de hiperviscosidade, avaliando a prevalência de sinais e sintomas, bem como características fisiopatológicas dessa entidade clínica. Foi revisado o prontuário de um paciente internado na enfermaria da Clínica Médica do Hospital Regional do Cariri (CE) no período de junho a julho de 2018. Além disso, foi realizada revisão de literatura em base de dados (PubMed®) direcionada ao tema proposto. O diagnóstico de mieloma múltiplo foi comprovado por mielograma, sendo prontamente iniciada a corticoterapia e avaliada a resposta clínica após essa terapêutica. Apesar de incomum e menos frequentemente relacionada ao mieloma múltiplo, a síndrome de hiperviscosidade está relacionada a uma grande taxa de mortalidade quando apresenta diagnóstico tardio. A terapia de primeira linha indicada para a síndrome de hiperviscosidade foi a plasmaferese, no entanto, as condições clínicas (instabilidade hemodinâmica) impossibilitaram sua realização. O desfecho deste caso foi o óbito do paciente. Concluiu-se que o diagnóstico precoce e a intervenção terapêutica estão diretamente relacionados à ocorrência de menor incidência de complicações relacionadas ao mieloma múltiplo e à síndrome de hiperviscosidade.
Multiple myeloma is a progressive and incurable B-cell neoplasm characterized by unregulated and clonal proliferation of plasmocytes in the bone marrow. Hyperviscosity syndrome is one of the complications related to monoclonal gammopathies and is considered an oncological emergency. The aim of this study was to describe the clinical condition of a patient diagnosed with multiple myeloma who presented hyperviscosity syndrome, evaluating the prevalence of symptoms and signs, as well as the pathophysiological characteristics of this clinical entity. The medical records of a patient admitted to the Internal Medicine ward of the Hospital Regional do Cariri (CE) from June to July of 2018 were reviewed. In addition, we conducted a literature review in a database (PubMed®) directed to the theme proposed. The diagnosis of multiple myeloma was confirmed by myelogram, and corticosteroid therapy was promptly initiated and the clinical response was evaluated after this therapy. Although uncommon and less frequently related to multiple myeoloma, hyperviscosity syndrome is related to a high mortality rate when diagnosed late. The first line therapy indicated to hyperviscosity syndrome was plasmapheresis; however, the clinical conditions (hemodynamic instability) precluded its performance. The outcome of this case was the patient's death. Thus, it was concluded that early diagnosis and therapeutic intervention are directly related to the occurrence of lower incidence of complications related to multiple myeloma and hyperviscosity syndrome.

Resumen La esofagitis necrotizante aguda es una entidad poco común que afecta sobre todo a ancianos. La presentación clínica más común es hemorragia digestiva alta. El pronóstico depende de las enfermedades de base con una mortalidad de hasta el 50 %. Se presenta el caso de un varón de 77 años con historia de una semana de melena, 3 episodios de hematemesis y epigastralgia. La endoscopia digestiva alta reveló una mucosa con necrosis en parches y fibrina en el esófago medio y distal. La biopsia de esófago fue compatible con necrosis de mucosa.
Abstract Acute necrotizing esophagitis is a rare entity that affects mainly elderly patients. The most common clinical presentation is upper gastrointestinal bleeding. The prognosis depends on the underlying diseases, with a mortality of up to 50%. This is the case of a 77-year-old male patient who presented with melena, three episodes of hematemesis, and epigastric pain for a week. Upper endoscopy revealed mucosa with spotty necrosis and fibrin in the middle and distal esophagus. Esophageal biopsy was compatible with mucosal necrosis.

La Hemorragia Digestiva (HD) es la pérdida o extravasación de sangre que se origina en cualquier segmento del tubo digestivo, alcanzando la luz esófago-gástrica, intestinal o colónica, constituye un problema frecuente de salud en el mundo y es considerada como causa mayor de morbimortalidad. En la mayoría de los casos la hemorragia digestiva se presenta de manera aguda y con importantes repercusiones sistémicas como hematemesis, melenas, hematoquecia, rectorragia, es importante tomar en cuenta la edad del paciente, comorbilidades, volumen, evolución y origen de la hemorragia digestiva, para determinar medidas urgentes en la estabilización de los pacientes, así como los cuidados de enfermería que se van a proporcionar con el propósito de minimizar la hemorragia y mantener la estabilidad hemodinámica. La Hemorragia Digestiva Alta (HDA) representa la emergencia médica gastroenterológica más frecuente en el mundo, con una prevalencia de 150 por 100 000 adultos por año con una mortalidad entre 10,0% al 20,0%, la Hemorragia Digestiva Baja (HDB) es potencialmente mortal, y puede manifestarse como anemia ferropénica, sangre en heces o hematoquecia; en el Ecuador en el año 2017 según el Instituto Nacional de Estadísticas y Censos (INEC), se reporta un ingreso hospitalario con CIE10 K922 (hemorragia digestiva no especificada) de 2 462 pacientes, con un total de egresos vivos de 2 375, y un total de 87 pacientes fallecidos; en el Hospital de Especialidades Carlos Andrade Marín del año 2017 al 2019 los pacientes con sangrado digestivo alto representan una mortalidad del 3,5 al 10,0% 1. La ruta planteada orienta al personal de Enfermería sobre la evolución, evaluación y manejo de los pacientes adultos con hemorragia digestiva.
Digestive Hemorrhage (HD) is the loss or extravasation of blood that originates in any segment of the digestive tract, reaching the esophagus-gastric, intestinal or colonic lumen, it is a frequent health problem in the world and is considered as a major cause of morbidity and mortality. In most cases, digestive bleeding occurs acutely and with significant systemic repercussions such as hematemesis, melena, hematochezia, rectal bleeding, it is important to take into account the age of the patient, comorbidities, volume, evolution and origin of digestive bleeding, to determine urgent measures in the stabilization of patients, as well as the nursing care that will be provided in order to minimize bleeding and maintain hemodynamic stability. Upper Gastrointestinal Bleeding (HDA) represents the most frequent gastroenterological medical emergency in the world, with a prevalence of 150 per 100 000 adults per year with a mortality between 10,0% to 20,0%, Low Gastrointestinal Bleeding (HDB) is life-threatening, and may ma- nifest as iron deficiency anemia, blood in stool, or hematochezia; in Ecuador in 2017 according to the National Institute of Statistics and Censuses (INEC), a hospital admission with ICD10 K922 (unspecified gastrointestinal bleeding) of 2 462 patients was reported, with a total of 2 375 living discharges, and a total of 87 deceased patients; In the Carlos Andrade Marín Specialties Hospital from 2017 to 2019, patients with upper digestive bleeding represent a mortality of 3,5 to 10,0% 1. The proposed route guides nursing staff on the evolution, evaluation and management of adult patients with gastrointestinal bleeding.

Haemosuccus pancreaticus (HP) is an uncommon cause of upper gastrointestinal (GI) bleeding, most often intermittent, making it difficult to diagnose, becoming fatal. It usually occurs in patients with chronic pancreatitis and is caused by the rupture of a visceral aneurysm within the main pancreatic duct. The association between pseudoaneurysm formation and pancreatitis is well established. Pseudoaneurysm occurs in 3.5%-10% of pancreatitis cases and its rupture is a rare but life-threatening complication of chronic pancreatitis occurring in 6%-8% of patients with pseudocysts and corresponds to less than 1% of cases of GI bleeding.Its diagnosis is challenging, given the intermittent nature of bleeding. Angiographic therapy is considered the first-choice treatment, especially in patients who are stable haemodynamically. We present a case of embolisation of inferior pancreaticoduodenal branches with polyvinyl alcohol microparticles in the treatment of HP.

RESUMEN El doble píloro es una comunicación anormal entre el antro gástrico y el bulbo duodenal y representa un raro hallazgo endoscópico. Se presentó un paciente de 80 años de edad, con antecedentes de hipertensión arterial, fumador inveterado, tomador de aspirina, que presentó melena aproximadamente 15 días antes del ingreso. La videoendoscopia reveló la existencia de dos orificios similares en el antro, que se comunicaban con el bulbo duodenal de manera independiente que fueron catalogados como píloros. La comunicación se constató con el paso del endoscopio a su través. Se impuso tratamiento médico con inhibidores de la bomba de protones y la evolución fue favorable. Es el cuarto caso reportado en la literatura en nuestro país y el primero en la provincia de Matanzas (AU).
ABSTRACT Double pylorus is an abnormal communication between the gastric antrum and the duodenal bulb and represents a rare endoscopic finding. It is presented the case of a patient aged 80 years, with a background of arterial hypertension, inveterate smoker, taking aspirin, who presented melena about 15 days before the admission. The video-endoscopy revealed the existence of two similar orifices in the antrum that were independently communicating with the duodenal bulb and they went catalogued like pylori. The communication was proved by passing the endoscope through it. He was treated with IBP (the Spanish acronym for proton bomb inhibitors) and the evolution was favorable. It is the fourth case reported in the literature in Cuba and the first one in Matanzas (AU).

Neuroendocrine carcinoma of esophagus represents less than 2% of cases of cancer of the esophagus. This presentation is extremely unusual, as this type of carcinoma typically presents with greater frequency in bronchopulmonary regions. The symptoms are usually associated with esophageal obstruction and include odynophagia, dysphagia and weight loss and are not usually associated with Carcinoid syndrome. The diagnosis requires one or more of the following positive immunohistochemical markers: Chromogranin A, synaptophysin or CD56 positive, as well as the presence of EMA and PANCK positive. We report the case of a male patient with diagnosis of neuroendocrine tumor of esophagus.

Primary gastric choriocarcinoma (PGC) is an extremely rare and highly invasive tumor with rapid hematogenous spread. We present the case of a 57-year-old female patient who started with hematemesis and progressive episodes of melena, weight loss and epigastralgia. It is derived from the National Institute of Neoplastic Diseases where gastroscopy and biopsy are performed. Histological analysis reported pattern suggestive of PGC; that was confirmed by immunohistochemical analysis for human chorionic gonadotrophin and fetal alpha protein. Subsequently, the patient underwent a radical D2 gastrectomy with splenic preservation and tail of the pancreas preservation. Unfortunately, her evolution was not favorable and died due to the progression of the disease.

El coriocarcinoma gástrico primario (CGP) es un tumor extremadamente raro, altamente invasivo y de rápida diseminación hematógena. Presentamos el caso de una paciente de 57 años que inicia con cuadro de hematemesis y, progresivamente, se le suman episodios de melena, baja de peso y epigastralgia. Es derivada al Instituto Nacional de Enfermedades Neoplásicas en donde se le realizan gastroscopía y biopsia. Así, el análisis histológico reportó patrón sugestivo para CGP; el cual se confirmó al realizarle a la paciente los estudios por imágenes necesarios y llevar a cabo el análisis inmunohistoquímico para gonadotrofina coriónica humana y alfa feto proteína. Posteriormente, a la paciente se le realiza una gastrectomía radical D2 con preservación esplénica y de cola de páncreas. Lamentablemente, su evolución no fue favorable y fallece por la progresión de la enfermedad.

Hemorragia digestiva alta (HDA) é uma emergência clínica exteriorizada através de melena, hematêmese, além de alterações hemodinâmicas decorrentes de perda volêmica. Existem vários diagnósticos etiológicos causadores de hemorragias digestivas altas; dentre eles, uma causa rara é lesão de Dieulafoy, sendo relacionada acerca de 2% dos casos de HDA. Neste relato, descreveremos um caso de lesão de Dieulafoy, evidenciando a relevância desta lesão como um importante diagnóstico diferencial nas causas de hemorragia digestiva alta. O procedimento diagnóstico e o manejo atual são fundamentados pela endoscopia digestiva alta. A hemostasia endoscópica é realizada, utilizando técnicas como eletrocoagulação, injeções com adrenalina e hemoclips.
Upper gastrointestinal bleeding (UGBI) is a clinical emergency externalized through melena, hematemesis and hemodynamic changes due to volume loss. There are a lot of etiological diagnosis of gastroduodenal hemorrhages, including Dieulafoy which is a rare cause related about 2% of the UGBI cases. In this report we describe a case of Dieulafoy lesion highlighting the importance of this lesion as a rare and important differential diagnosis in cases of upper gastrointestinal bleeding. The current diagnostic and management is justified by endoscopy. Endoscopic hemostasis is performed using techniques such as electrocoagulation, injections of adrenaline and hemo-clips.

Os tumores estromais gastrointestinais (GIST) são incomuns e apresentam elevada similaridade histológica com as neoplasias de músculo liso e de nervo periférico. Este trabalho relata e caracteriza GIST em cães do ponto de vista epidemiológico, clínico-laboratorial, anatomopatológico e imuno-histoquímico, com base na análise retrospectiva de três cães, machos, com média de idade de 10 anos, variando de porte médio a grande e peso médio de 18.5±6kg. As alterações clínicas foram progressivas e inespecíficas de quadro gastrointestinal crônico, tais como prostração, anorexia, perda de peso e melena. Anemia não regenerativa e leucocitose foram os principais achados laboratoriais. Macroscopicamente, os tumores apresentavam média de 19cm no eixo maior, localizados em jejuno e ceco, com a superfície ulcerada, e exibiam áreas de necrose. Na avaliação microscópica, os casos apresentaram proliferação de células fusiformes, arranjadas em feixes longos densamente celulares, que foram vimentina e CD117 positivas, com diferenciação neural (S100 positivo), muscular (actina e desmina positivas) e anaplásica, cuja morfologia caracteriza neoplasias malignas com sobrevida de um dia a 12 meses. O GIST deve ser um dos diagnósticos diferenciais a serem considerados entre as neoplasias mesenquimais do trato gastrointestinal que acometem cães, e o diagnóstico final necessita de imuno-histoquímica.(AU)
Gastrointestinal stromal tumors (GIST) are uncommon and show high histological similarity with smooth muscle and peripheral neuron tumors. This paper reported three cases of gastrointestinal stromal tumor (GIST) showing its clinical and laboratorial presentation, and gross, microscopical and immunohistochemical features. Clinical signs and symptoms of the animals studied were progressive and characterized by nonspecific chronic gastrointestinal disorders such as depression, anorexia, weight loss and melena. Non regenerative anemia and leukocytosis were the main laboratory findings. Grossly, tumors were 19cm big, ulcerated and with necrotic areas. Microscopically, the tumors were malignant spindle cell proliferation with positivity to vimentine and CD117, with neural (S100+), myogenic (desmine + and smooth muscle actine+) and anaplasic differentiation. GIST should be one of the differential diagnoses to be considered among the mesenchymal neoplasms of the gastrointestinal tract of dogs.(AU)
