Emergency medicine updates: Upper gastrointestinal bleeding.

INTRODUCTION: Upper gastrointestinal bleeding (UGIB) is a condition commonly seen in the emergency department (ED). Therefore, it is important for emergency clinicians to be aware of the current evidence regarding the diagnosis and management of this disease. OBJECTIVE: This paper evaluates key evidence-based updates concerning UGIB for the emergency clinician. DISCUSSION: UGIB most frequently presents with hematemesis. There are numerous causes, with the most common peptic ulcer disease, though variceal bleeding in particular can be severe. Nasogastric tube lavage for diagnosis is not recommended based on the current evidence. A hemoglobin transfusion threshold of 7 g/dL is recommended (8 g/dL in those with myocardial ischemia), but patients with severe bleeding and hemodynamic instability require emergent transfusion regardless of their level. Medications that may be used in UGIB include proton pump inhibitors, prokinetic agents, and vasoactive medications. Antibiotics are recommended for those with cirrhosis and suspected variceal bleeding. Endoscopy is the diagnostic and therapeutic modality of choice and should be performed within 24 h of presentation in non-variceal bleeding after resuscitation, though patients with variceal bleeding may require endoscopy within 12 h. Transcatheter arterial embolization or surgical intervention may be necessary. Intubation should be avoided if possible. If intubation is necessary, several considerations are required, including resuscitation prior to induction, utilizing preoxygenation and appropriate suction, and administering a prokinetic agent. There are a variety of tools available for risk stratification, including the Glasgow Blatchford Score. CONCLUSIONS: An understanding of literature updates can improve the ED care of patients with UGIB.

Transient pulmonary and gastric bleeding after iopamidol administration in a patient with marginal zone lymphoma: a case report.

BACKGROUND: Iopamidol is a non-ionic, water-soluble iodine contrast agent that is considered safe for intravenous or intra-arterial administration and is widely used both in the general population and in patients undergoing oncological treatment. While adverse reactions to iopamidol have been documented, to date, no pulmonary and gastric hemorrhages induced by iopamidol have been reported in oncology patients. We report the first case of this complication. CASE PRESENTATION: We report the case of a 60-year-old woman with marginal zone lymphoma who was receiving antineoplastic therapy. As part of the investigation for the condition, she underwent chest enhancement CT with iopamidol. Shortly thereafter(within five minutes), she experienced hemoptysis and hematemesis. She was intubated and admitted to the intensive care unit. Pre- and post-contrast images demonstrated the course of the hemorrhage. Flexible bronchoscopy and gastroscopy on the following day showed no active bleeding, and the patient recovered completely after antiallergy treatment. We speculate that contrast-induced hypersensitivity was the most likely cause of the transient pulmonary and gastric bleeding. CONCLUSION: Although rare, the complications of iopamidol, which may cause allergic reactions in the lungs and stomach, should be considered.

[Endovascular Repair of Aortic Injury Caused by Esophageal Foreign Body:Report of a Case].

A 51-year-old man visited to our hospital because of chest discomfort and hematemesis. He was diagnosed with Mallory-Weiss syndrome and followed in outpatient clinic. One week later, he visited our hospital again for fever and discomfort. Chest computed tomography (CT) showed a foreign body perforated in the mediastinum in the upper esophagus, and he was urgently hospitalized for surgical removal of esophageal foreign body. Before surgery he vomited the esophageal foreign body with a lot of blood. Hematemesis was stopped spontaneously and contrast-enhanced CT revealed a pseudoaneurysm in the distal aortic arch, so thoracic endovascular aortic repair (TEVAR) was performed to prevent rupture. Esophageal endoscopy found that the site of esophageal injury healed spontaneously, so the patient was followed conservatively with antibiotics. He was discharged on postoperative day 18 uneventfully. TEVAR was an effective treatment for aortic injury caused by esophageal foreign body in our case.

Overt gastrointestinal bleeding secondary to left inferior phrenic artery pseudoaneurysm postgastric bypass surgery.

Bleeding from a visceral artery pseudoaneurysm (VAPA) is a rare but significant complication of bariatric surgery. Patients may present with gastrointestinal (GI) haemorrhage in the forms of haematemesis, melaena, haematochezia or haemodynamic compromise. Although CT angiogram, endoscopy and laparoscopy form essential parts of diagnostic assessment, small pseudoaneurysms with intermittent bleeding may be overlooked. We report the case of a man in his 40s who presented to the emergency department with massive GI bleeding and subsequent haemodynamic instability, secondary to a pseudoaneurysm from a vascular injury during a recent bariatric procedure. This case highlights the diagnostic challenges of obscure, intermittent bleeding involving the bypassed stomach with unremarkable investigation findings, and aims to raise awareness among clinicians in considering the less common postgastric-bypass complications.

Exsanguinated to death by a perforated duodenal ulcer: Masquerader apprehended on autopsy.

ABSTRACT: Gastroduodenal perforation commonly due to spontaneous perforation of a pre-existing peptic ulcer is a surgical emergency. On laparotomy, approximately 60%-70% perforations are duodenal and 15%-20% gastric. The most prevalent etiology are Helicobacter pylori infection in 65%-70% and non-steroidal anti-inflammatory drugs (NSAIDS) abuse in 30%-50% cases depending on the prevalence of H. pylori infection. We report here the autopsy findings in a 29-year-old male who collapsed suddenly in the emergency room of our hospital after a bout of massive hematemesis.

Gastrointestinal stromal tumor of the duodenum presenting with shock and massive upper and lower gastrointestinal bleeding: a case report and review of the literature.

BACKGROUND: Due to rarity of duodenal GISTs, clinicians have few information about its clinical features, diagnosis, management and prognosis. CASE REPORT: We report a case of promptly diagnosed duodenal GIST in a 61-year-old Egyptian man presented shocked with severe attack of hematemesis and melena. Upper gastroduodenal endoscopy was done and revealed a large ulcerating bleeding mass at first part of duodenum 4 hemo-clips were applied with good hemostasis. An exploratory laparotomy and distal gastrectomy, duodenectomy and gastrojejunostomy were performed. The morphology of the mass combined with immunohistochemistry was consistent with duodenal gastrointestinal stromal tumours (GISTs) of high risk type. The patient is on amatinib one tablet daily and he was well with no evidence of tumor recurrence. CONCLUSION: despite being rare, emergency presentation with sudden severe, life-threatening hemorrhagic shock duodenal GISTs might be a cause of potentially lethal massive combined upper and lower gastrointestinal bleeding which is the key feature of this rare and challenging tumor.

Postoperative delayed massive bleeding in gastric cancer: a case report.

BACKGROUND: Postoperative delayed bleeding of gastric cancer is a complication of radical gastrectomy with low incidence rate and high mortality. CASE PRESENTATION: This case report presents the case of a 63-year-old female patient of Mongolian ethnicity who was diagnosed with gastric malignancy during a routine medical examination and underwent Billroth's I gastric resection in our department. However, on the 24th day after the surgery, she was readmitted due to sudden onset of hematemesis. Gastroscopy, abdominal CT, and digital subtraction angiography revealed postoperative anastomotic fistula, rupture of the duodenal artery, and bleeding from the abdominal aorta. The patient underwent three surgical interventions and two arterial embolizations. The patient's condition stabilized, and she was discharged successfully. CONCLUSION: Currently, there are no specific guidelines for the diagnosis and treatment of pseudoaneurysms in the abdominal cavity resulting from gastric cancer surgery. Early digital subtraction angiography examination should be performed to assist in formulating treatment plans. Early diagnosis and treatment contribute to an improved overall success rate of rescue interventions.

Surgical repair of an aortoesophageal fistula after salvage thoracic endovascular aortic repair: a case report.

BACKGROUND: An aortoesophageal fistula can prove to be fatal. Salvage thoracic endovascular aortic repair as a bridging therapy and radical surgery with thoracotomy should be considered while treating aortoesophageal fistula without spontaneous closure. Moreover, it is essential to select a technique that reduces the risk of reinfection. Here we report a rare case of a ruptured thoracic aortic aneurysm related to esophageal perforation by a fish bone that led to massive hematemesis and shock, and the surgical treatment of an aortoesophageal fistula that developed after salvage thoracic endovascular aortic repair. CASE PRESENTATION: A 70-year-old Japanese female patient was admitted with hematemesis, thoracic pain, and shock related to esophageal perforation of a ruptured descending aortic aneurysm caused by fish bone aspiration and esophageal perforation 1 month previously. An emergency thoracic endovascular aortic repair was performed. Postoperatively, an aortoesophageal fistula that remained open and a food intake-related increase in the inflammatory response was noted. Radical blood-vessel prosthesis implantation and fistula closure were performed. The patient's postoperative course was favorable and the patient was discharged 22 days after the blood vessel prosthesis implantation. CONCLUSION: Such a case of rupture of a descending aortic aneurysm related to perforation by a fish bone and an aortoesophageal fistula is considerably rare. Thus, we report the therapeutic strategy of this particular case and review the relevant literature.

Sclerosing mesenteritis as a cause of porto-mesenteric vascular obstruction.

A woman in her 20s presented with haematemesis, post-prandial abdominal pain, weight loss and anaemia. Imaging revealed a non-enhancing mass in the retroperitoneal space along the mesenteric plane, encasing the porto-mesenteric vasculature. Endoscopy showed oesophageal varices. She was diagnosed with sclerosing mesenteritis, causing extrinsic compression of the portal vein and superior mesenteric artery. She underwent endoscopic variceal ligation and received prednisolone and tamoxifen. After 3 months, her post-prandial pain improved, and she did not have further bleeding episodes.

Acute liver failure with a massive upper GI bleed meeting the criteria of MIS-C.

Multisystem inflammatory syndrome in children (MIS-C) is a known complication of COVID-19. There is still limited knowledge about this condition. Here, we report the case of a previously healthy toddler boy, who presented with acute liver failure and duodenal lesions resulting in severe haematemesis and haemorrhagic shock, requiring intensive care unit care. The patient had persistent transaminitis, a deranged coagulation profile, inflammatory markers were elevated, and laboratory tests were negative for common infectious hepatitis aetiologies as well as COVID-19 Reverse transcription polymerase chain reaction. His COVID-19 antibody was reactive. Upper gastrointestinal endoscopy revealed a Forrest grade III duodenal ulcer. Looking into the constellation of symptoms and laboratory findings a confirmed diagnosis of acute viral hepatitis caused by MIS-C was made. Hence, he was given intravenous methylprednisolone along with intravenous immunoglobulins, after which he improved clinically and transaminitis resolved. The patient was discharged on clinical improvement and was doing fine on follow-up up to 6 months.

Infectious endarteritis in aortic coarctation: two spectra of an infrequent disease.

OBJECTIVE: To describe two different degrees of clinical commitment and results in the evolution of infectious endarteritis in patients without a previous diagnosis of aortic coarctation. CASE DESCRIPTION: Two male patients aged 13 and 9 years old were admitted. The first due to a fever for 2 months, which started after dental cleaning, and the second due to high blood pressure, both patients with asthenia and weight loss. In the first case, the transthoracic echocardiogram showed aortic coarctation, and the transesophageal echocardiogram showed the presence of vegetations in the post-coarctation area, without pseudoaneurysms, with blood culture positive for Streptococcus mitis. This patient was treated for six weeks with crystalline penicillin, resolving the infection without complications. The second case was assessed for high blood pressure with a history of fever, and was treated with antibiotics. When performing a transthoracic echocardiogram, aortic coarctation was observed with a saccular image classified as a pseudoaneurysm by angiography and tomography. Blood culture was negative, and the patient developed an episode of hematemesis whose initial etiology could not be determined. Before surgical repair, he had a second episode of copious hematemesis with hypovolemic shock and death. COMMENTS: We need to have a high index of clinical suspicion to establish the diagnosis of aortic coarctation complicated by endarteritis and start the appropriate antibiotic treatment, always maintaining surveillance for the early detection of pseudoaneurysms.

Esofagitis necrotizante aguda / Acute necrotizing esophagitis / Esofagite necrotizante aguda

La esofagitis necrotizante aguda es un trastorno poco común que puede ser causa de hemorragia digestiva alta. Predomina en el sexo masculino en la sexta década de la vida. El diagnóstico es endoscópico y muestra una mucosa esofágica de apariencia negra que afecta al esófago distal en toda su circunferencia y se detiene abruptamente en la unión gastroesofágica. Clínicamente suele presentarse con hematemesis y melenas, shock hipovolémico por sangrado masivo, siendo otras manifestaciones el dolor epigástrico, molestia retroesternal y disfagia. Se vincula a pacientes con antecedentes de enfermedad cardiovascular, alcoholismo, diabetes mellitus, desnutrición, hernia hiatal, estenosis gastroduodenal, cáncer, así como pacientes en shock, traumatizados, sometidos a cirugía mayor e inmunosuprimidos. El tratamiento se basa en fluidoterapia, inhibidores de la bomba de protones y suspensión de la vía oral, siendo controvertido el uso de antibioticoterapia. Su pronóstico es malo y dependerá de la gravedad de la enfermedad esofágica y del terreno del paciente, con una mortalidad de hasta el 36 %. Presentamos el caso clínico de un paciente de 81 años, hipertenso, que presenta hematemesis, confirmándose en la endoscopía una esofagitis necrotizante aguda, que evoluciona favorablemente con tratamiento médico.

Acute necrotizing esophagitis is a rare disorder that can cause upper gastrointestinal bleeding. It predominates in males in the sixth decade of life. The diagnosis is endoscopic and shows a black-appearing esophageal mucosa that affects the entire circumference of the distal esophagus and stops abruptly at the gastroesophageal junction. Usually, patients present with hematemesis and melena, with other manifestations such as epigastric pain, retrosternal discomfort, dysphagia, and hypovolemic shock. Almost all patients reported comorbidities: cardiovascular disease, alcoholism, diabetes mellitus, malnutrition, hiatal hernia, gastroduodenal stenosis, and malignant neoplasia; is related as well to patients with shock, trauma, undergoing major surgery, and immunosuppression. The treatment is based on fluid reposition, proton pump inhibitors and suspension of the oral route, the use of antibiotic therapy being controversial. Its prognosis is poor and will depend on the severity of the esophageal disease and the patient comorbidities, with a mortality rate up to 36 %. Case: A 81-year-old male patient with hypertension, who presented hematemesis, confirmed by endoscopy as acute necrotizing esophagitis, whose evolution was favorable with medical treatment.

A esofagite necrosante aguda é uma doença rara que pode causar hemorragia digestiva alta. Predomina no sexo masculino na sexta década de vida. O diagnóstico é endoscópico e mostra uma mucosa esofágica circunferencial difusa com aspecto preto que envolve quase universalmente o esôfago distal e para abruptamente na junção gastroesofágica. Clinicamente, geralmente se apresenta com hematêmese e melena, com outras manifestações sendo dor epigástrica, desconforto retroesternal, disfagia e choque hipovolêmico. Está relacionado a pacientes com histórico de doenças cardiovasculares, alcoolismo, diabetes mellitus, desnutrição, hérnia hiatal, estenose gastroduodenal e neoplasia maligna, bem como pacientes em choque, trauma, cirurgia de grande porte e imunossupressão. O tratamento é a medicação dietética higiênica baseada em fluidoterapia, inibidores da bomba de prótons e suspensão da via oral, sendo o uso de antibioticoterapia controverso. Seu prognóstico é ruim e dependerá da gravidade da doença esofágica e do terreno do paciente, com mortalidade de até 36 %. Apresentamos o caso clínico de um paciente hipertenso de 81 anos que apresentou hematêmese, confirmada por endoscopia como esofagite necrosante aguda, que evoluiu favoravelmente com tratamento higiênico-dietético e medicamentoso.

Rotura aórtica masiva secundaria a espondilodiscitis por Staphylococcus aureus / Massive aortic rupture secondary to Staphylococcus aureus spondylodiscitis

Introducción: presentamos un caso inusual de rotura aórtica múltiple secundaria a espondilodiscitis por Staphylococcus aureus sensible a meticilina. Caso clínico: varón de 71 años que ingresa en nuestro hospital para el estudio programado de una espondilodiscitis T7-T8 refractaria a tratamiento empírico antibiótico. El decimoquinto día de su ingreso el paciente presenta una hematemesis masiva con dos paradas cardiorrespiratorias. Tras ser reanimado en dos ocasiones, se realiza una endoscopia en el quirófano que sugiere la presencia de una fístula aortoentérica primaria. A su vez, en una tomografía computarizada de seguimiento se evidencia sangrado activo en la aorta torácica. Realizamos una angiografía diagnóstica en la que apreciamos tres puntos de ruptura aórtica. Se precisa la implantación de endoprótesis cubiertas para el control del sangrado: un dispositivo en la aorta torácica (Gore C-TAG®) y otro a nivel abdominal (Aortic Begraft®). Discusión: la aortitis es una complicación poco común de la espondilodiscitis con una tasa alta de mortalidad. Un alto índice de sospecha es clave para su temprano diagnóstico y tratamiento. La antibioterapia es obligatoria y el tratamiento endovascular puede usarse como terapia puente en emergencias. Es un procedimiento rápido que permite la estabilización hemodinámica del paciente antes de una cirugía abierta aórtica definitiva.(AU)

Introduction: we present an unusual case with multiple aortic ruptures secondary to methicillin-sensitive Staphylococcus aureus thoracic spondylodiscitis. Case report: the patient was a 71-year-old man admitted to our hospital for scheduled study of an infectious spondylodiscitis D7-D8 refractory to empirical antibiotic therapy. Fifteen days after admission, the patient began with massive hematemesis. After being resuscitated from two cardiac arrests, an endoscopy was carried out in the operating room suggesting presence of a primary aortoenteric fistula and, at the same time, in a follow-up computed tomography an active bleeding in thoracic aorta was shown. We performed a diagnostic angiography; three different sites of rupture were observed and two covered endogfrats were placed for bleeding control of thoracic and abdominal aorta: one device in thoracic aorta (Gore C-TAG®) and another one in abdominal aorta (Aortic Begraft®). Discussion: aortitis is an uncommon complication of spondylodiscitis, with a high mortality rate. A high index of suspicion is key to its diagnosis and prompt treatment. Antibiotherapy is mandatory and endovascular treatment can be used as a bridge therapy in emergency, it is a fast procedure that can secure hemodynamical stabilization prior to definitive aortic open repair.(AU)

Intususcepción yeyunogástrica retrógrada en un paciente con historia de gastroyeyunostomía hace 20 años: reporte de caso y revisión de la literatura / Retrograde jejunogastric intussusception in a patient with underlying history of gastrojejunostomy 20 years ago: Case report and literature review

Resumen La intususcepción yeyunogástrica es una complicación rara, pero potencialmente fatal de acuerdo con el momento de su diagnóstico e intervención. Debido a su baja incidencia, se requiere de una alta sospecha diagnóstica, basada en la clínica y los antecedentes quirúrgicos. En el presente reporte se expone el caso de un paciente de 74 años, con historia de gastroyeyunostomía y cerclaje duodenal realizados como parte del manejo de úlcera duodenal 20 años atrás. Se presentó por urgencias luego de 7 días de inicio de los síntomas caracterizados por dolor, intolerancia a la vía oral y hematemesis. Su diagnóstico se realizó mediante endoscopia de vías digestivas altas y su manejo definitivo, mediante gastrectomía subtotal y reconstrucción en Y de Roux transmesocólica por laparotomía.

Abstract Retrograde jejunogastric intussusception is a rare but potentially fatal complication, according to the time of diagnosis and intervention. Due to its low incidence, a high diagnostic suspicion is required, based on the clinical and surgical history. This study presents the case of a patient of 74 years old with a history of gastrojejunostomy and duodenal cerclage performed as part of duodenal ulcer treatment 20 years ago. The patient was admitted to the emergency unit, after 7 days of having symptoms such as pain, intolerance to oral intake, and hematemesis. Diagnosis was performed by upper digestive tract endoscopy and the final treatment by subtotal gastrectomy and transmesocolic Roux-en-Y reconstruction by laparotomy.

Ligadura de varices esofágicas por videoendoscopia en pacientes con hemorragia digestiva alta / Ligature of varicose veins by videoendoscopy in patients with upper digestive bleeding

Introducción: Las varices esofágicas son canales vasculares que unen la circulación venosa portal y la sistémica. Se forman como consecuencia de la hipertensión portal, predominantemente en la submucosa del tercio inferior del esófago. Objetivo: Caracterizar a pacientes con rotura de varices esofágicas según principales variables clinicoepidemiológicas y terapéutico-endoscópicas. Métodos: Se realizó un estudio observacional, descriptivo y longitudinal de 20 pacientes con hemorragia digestiva alta por rotura de varices esofágicas, los cuales recibieron tratamiento endoscópico con bandas elásticas en el Servicio de Gastroenterología del Hospital General Docente Dr. Juan Bruno Zayas Alfonso de Santiago de Cuba, de noviembre de 2016 a febrero de 2018. En el análisis estadístico se utilizó el porcentaje como medida de resumen y se aplicó la prueba de independencia de la Χ2 para identificar alguna asociación significativa entre variables. Resultados: Existió un predominio del sexo masculino (80,0 %) y del grupo etario de 51 a 60 años (40,0 %). La mayoría de los afectados presentó cirrosis hepática (60,0 %) como causa de la hipertensión portal y hematemesis (50,0 %) como forma de hemorragia digestiva alta; asimismo, el gran tamaño de las varices fue el principal factor de riesgo asociado a la rotura (70,0 %) y, luego de practicado el tratamiento endoscópico, no se produjo resangrado en la casi totalidad de los pacientes (95,0 %). Conclusiones: La aplicación de este procedimiento terapéutico resultó ser satisfactoria y no provocó complicación alguna.

Introduction: The esophageal varicose veins are vascular channels that unite the portal venous and systemic circulation. They are formed as consequence of the portal hypertension, predominantly in the submucosa of the inferior section of the esophagus. Objective: To characterize patients with break of esophageal varicose veins according to main clinical epidemiological and therapeutic-endoscopic variables. Methods: An observational, descriptive and longitudinal study of 20 patients with upper digestive bleeding due to break of esophageal varicose veins was carried out, they received endoscopic treatment with banding in the Gastroenterology Service of Dr. Juan Bruno Zayas Alfonso Teaching General Hospital in Santiago de Cuba, from November, 2016 to February, 2018. In the statistical analysis the percentage was used as summary measure and the chi-square test was applied to identify the existence of some significant association among variables. Results: There was a prevalence of the male sex (80.0 %) and the 51 to 60 age group (40.0 %). Most of the patients presented liver cirrhosis (60.0 %) as cause of the portal hypertension and hematemesis (50.0 %) as form of upper digestive bleeding; also, the great size of the esophageal varicose veins was the main risk factor associated with the break (70.0 %) and, after the implementation of the endoscopic treatment, there was no second bleeding in almost all the patients (95.0 %). Conclusions: The application of this therapeutic procedure was satisfactory and it didn't cause any complication.

Esófago negro como causa de hemorragia digestiva alta: reporte de un caso / Black esophagus as a cause of upper gastrointestinal bleeding: a case report

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.

Cuidados de Enfermería en pacientes con hemorragia digestiva que ingresan a la Unidad Técnica de Gastroenterología

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.

Nutritórax: una complicación infrecuente de la nutrición parenteral / Nutrithorax: an uncommon complication of parenteral nutrition

INTRODUCCIÓN: la nutrición parenteral (NP) es una modalidad de soporte nutricional con posibles complicaciones, en parte asociadas al catéter venoso central (CVC). El quilotórax consiste en el derrame de líquido linfático de origen intestinal en el espacio pleural. CASO CLÍNICO: varón de 57 años ingresado para colecistectomía. Presenta un postoperatorio complicado que requiere reposo digestivo y NP. Posteriormente presenta disnea y dolor torácico con derrame pleural bilateral y pericárdico. Inicialmente se interpretó como un quilotórax, por su aspecto lechoso y su contenido en triglicéridos. La TC confirmó la malposición del CVC con salida de NP a nivel del tronco venoso innominado. Fue intervenido quirúrgicamente, realizándose un lavado del mediastino anterior y la reparación de la perforación. La evolución posterior fue favorable. DISCUSIÓN: la extravasación de la NP al espacio pleural es una complicación infrecuente pero posible de la administración de NP por vía central. Por tanto, debe tenerse en cuenta en el diagnóstico diferencial

INTRODUCTION: parenteral nutrition (PN) is commonly used as a nutritional support option. It may cause complications, partly due to a central venous access. Chylothorax is an accumulation of lymphatic fluid in the pleural space. CASE REPORT: a 57-year-old man was admitted for cholecystectomy. A complicated postoperative period required PN. Cardiorespiratory symptoms started while receiving PN, and a bilateral pleural and pericardial effusion was identified. It was initially interpreted as chylothorax due to its milky appearance and high triglyceride content. A CT scan confirmed a malposition of the CVC with PN leakage at the level of the innominate venous trunk. It was surgically repaired. DISCUSSION: parenteral nutrition leakage is an unusual complication of PN. It should be included in the differential diagnosis of pleural effusion

Hematoma disecante del esófago a causa de abdomen agudo quirúrgico / Dissecting Hematoma of the Esophagus due to Acute Surgical Abdomen

RESUMEN El hematoma disecante del esófago es poco frecuente y solo existen pocos casos registrados en la literatura. Generalmente, se presenta después de un trauma asociado a procedimientos endoscópicos o de forma espontánea. Se describe clínicamente con la triada clásica de dolor torácico, odinofagia, disfagia o hematemesis. Se ha relacionado con un aumento rápido de la presión intraesofágica o un mecanismo de deglución anómala particularmente en presencia de trastornos de la hemostasia. La mayoría de los pacientes tienen un buen pronóstico pues resuelven con tratamiento conservador. Presentamos el caso clínico de un paciente con diagnóstico de hematoma disecante de esófago con ruptura a cavidad abdominal que causó hemoperitoneo importante. Se realiza una revisión del tema(AU)

ABSTRACT Dissecting hematoma of the esophagus is a rare condition and there are only few cases reported by the literature. Generally, it occurs after trauma associated with endoscopic procedures or spontaneously. It is described clinically with the classic triad of chest pain, odynophagia, dysphagia or hematemesis. It has been associated with a rapid increase in intra-esophageal pressure or an abnormal swallowing mechanism particularly in the presence of haemostasis disorders. Most patients have a good prognosis because they obtain a solution by means of a conservative treatment. We present the clinical case of a patient with a diagnosis of dissecting hematoma of the esophagus with rupture to the abdominal cavity causing significant hemoperitoneum. A review of the subject is carried out(AU)
