Colocación de prótesis esofágica para el fracaso del tratamiento endoscópico / Esophageal stent placement for endoscopic treatment failure

Up until approximately 10 years ago, the treatment for acute refractory esophageal variceal bleeding was balloon tamponading. Esophageal fully covered self-expanding stents are considered as effective as balloons and also much safer. They are kept in situ for longer periods, what eases the access to more definitive treatments with a low complication rate. We present 6 cases of patients with cirrhosis and massive bleeding due to esophageal varices refractory to conventional treatment, successfully treated with an esophageal fully covered self-expanding stent. There were no major complications, achieving an effective bleeding control in all cases.(AU)

Gastric variceal bleeding as a form of presentation of a pancreatic neuroendocrine tumor / Sangrado por varices gástricas como forma de presentación de un tumor neuroendocrino pancreático

NETs (neuroendocrine tumors) constitute a heterogeneous group of epithelial-type neoplasms with a predominantly neuroendocrine differentiation. Although the most common locations are the pancreas, digestive tract, and lung, this type of neoplasm can arise in virtually any organ in the body. They are rare tumors with a wide variety of clinical presentations. Symptomatic tumors are more frequent in younger patients and present at more advanced pathological stages. We present the case of a 42-year-old male with idiopathic splenomegaly and bicytopenia (anaemia and thrombocytopenia) under study by haematology department who was admitted due to an episode of melena and hemoglobin of 4.5 mg/dl. Isolated gastric varices (IGV1) with red spots were confirmed at gastroscopy and endoscopic variceal obturation using cyanoacrylate was performed in two sessions. An endoscopic ultrasonography was performed, showing thrombosis of the splenic vein extending towards the splenoportal confluence with anechoic serpiginous structures outside and inside the gastric wall suggestive of collateral circulation with gastric varices (GV). An increase in portal caliber was observed, with no signs of liver cirrhosis. Computed tomography confirms the findings. Two months/week/days later he was readmitted with rebleeding signs after starting anticoagulant treatment, so it was decided to perform a splenectomy due to failure of the endoscopic treatment. Histology revealed infiltration of the spleen by a well-differentiated neuroendocrine tumor (NET). Gallium PET/CT and Octreotid scan showed uptake in the body and tail of the pancreas with positivity for somatostatin receptors previously undetected by other means. Finally, treatment was completed with distal pancreatectomy and splenoportal axis trombectomy with vascular esplenic resection and the patient was discharged from hospital.(AU)

Hemorragia por hipertensión portal (HTP) secundaria a variz éctopica en ureteroileostomía tipo Bricker en un paciente con dos trombosis precoces consecutivas de la derivación portosistémica intrahepática transyugular (TIPS) / Portal hypertension hemorrhage secondary to a stomal varicose vein in a patient with two consecutive thrombosis of a transjugular intrahepatic portosystemic shunt (TIPS)

Less than 5% of patients with liver cirrhosis (LC) with portal hypertension (PH) develop atypical shunt (in regions other than the esophagus or the stomach). Within this group are varices associated with a stoma, for example the ones associated with an uretero-ileostomy which are infrequent. They are a diagnostic and therapeutic challenge, as they can cause hemorrhages due to PH. We present a clinical case about stoma varicose bleeding as the latest guidelines for the management of PH do not mention them or their treatment due to their low incidence.(AU)

Dieulafoy’s lesion in the cecal pole diagnosed by video-capsule endoscopy. A rare cause of lower gastrointestinal bleeding / Lesión de Dieulafoy en el cecal polo diagnosticado por videocápsula endoscopia. Una causa rara de sangrado gastrointestinal bajo

Dieulafoy's lesion is a rare vascular malformation that can cause massive acute gastrointestinal hemorrhage threatening the patient's life. This correspondence to the editor outlines the clinical presentation of a patient in whom, owing to the utilization of capsule endoscopy followed by subsequent colonoscopy, a diagnosis of hemorrhage resulting from a Dieulafoy's lesion located in the colon, a relatively uncommon site, was successfully established. Following intervention involving the application of hemoclips, the patient experienced a favorable clinical evolution.(AU)

Endoscopia urgente frente a endoscopia precoz: ¿tiene algún papel la endoscopia urgente en la hemorragia digestiva alta aguda no varicosa? / Urgent endoscopy versus early endoscopy: Does urgent endoscopy play a role in acute non-variceal upper gastrointestinal bleeding?

Introducción: Las principales guías de práctica clínica recomiendan la realización de endoscopia dentro de las 24horas posteriores a la admisión en urgencias en pacientes con hemorragia digestiva alta no variceal. Sin embargo, es un margen de tiempo muy amplio y el papel de la endoscopia urgente (<6horas) es controvertido. Material y métodos: Estudio prospectivo observacional realizado en Hospital Universitario La Paz, donde son seleccionados todos los pacientes, desde el 1 de enero de 2015 hasta el 30 de abril de 2020, que acudieron a urgencias y fueron sometidos a endoscopia por sospecha de hemorragia digestiva alta. Se establecieron dos grupos de pacientes: endoscopia urgente (<6horas) y precoz (6-24horas). El objetivo primario del estudio fue la mortalidad a los 30días. Resultados: Un total de 1.096 pacientes fueron incluidos, de los cuales 682 fueron sometidos a endoscopia urgente. La mortalidad a los 30 días fue del 6% (5% vs 7,7%, p=0,064) y del resangrado fue del 9,6%. No hubo diferencias estadísticamente significativas en la mortalidad, resangrado, necesidad de tratamiento endoscópico, cirugía y/o embolización, pero sí en la necesidad de transfusión (57,5% vs 68,4%, p<0,001) y el número de concentrados de hematíes transfundidos (2,85±4,01 vs 3,51±4,09, p=0,008). Conclusión: La endoscopia urgente, en pacientes con hemorragia digestiva alta aguda, también el subgrupo de alto riesgo (GBS ≥ 12), no se asoció con una mortalidad menor a los 30 días que la endoscopia precoz. Sin embargo, en los pacientes con lesiones endoscópicas de alto riesgo (Forrest I-IIB), fue un predictor significativo de menor mortalidad. Por lo tanto, se requieren más estudios para la identificación correcta de pacientes, que se beneficien de esta actitud médica (endoscopia urgente). (AU)

Introduction: The main clinical practice guidelines recommend endoscopy within 24hours after admission to the Emergency Department in patients with non-variceal upper gastrointestinal bleeding. However, it is a wide time frame and the role of urgent endoscopy (<6hours) is controversial. Material and methods: Prospective observational study carried out at La Paz University Hospital, where all patients were selected, from January 1, 2015 to April 30, 2020, who attended the Emergency Room and underwent endoscopy for suspected upper gastrointestinal bleeding. Two groups of patients were established: urgent endoscopy (<6hours) and early endoscopy (6-24hours). The primary endpoint of the study was 30-day mortality. Results: A total of 1096 were included, of whom 682 underwent urgent endoscopy. Mortality at 30days was 6% (5% vs 7.7%, P=.064) and rebleeding was 9.6%. There were no statistically significant differences in mortality, rebleeding, need for endoscopic treatment, surgery and/or embolization, but there were differences in the necessity for transfusion(57.5% vs 68.4%, P<.001) and the number of concentrates of transfused red blood cells (2.85±4.01 vs 3.51±4.09, P=.008). Conclusion: Urgent endoscopy, in patients with acute upper gastrointestinal bleeding, as well as the high-risk subgroup (GBS ≥12), was not associated with lower 30-day mortality than early endoscopy. However, urgent endoscopy in patients with high-risk endoscopic lesions (ForrestI-IIB), was a significant predictor of lower mortality. Therefore, more studies are required for the correct identification of patients who benefit from this medical approach (urgent endoscopy). (AU)

Impact of left atrial appendage closure in patients on anticoagulation for atrial fibrillation and recurrent or chronic gastrointestinal bleeding / Impacto del cierre de la orejuela izquierda en pacientes anticoagulados por fibrilación auricular y con sangrado gastrointestinal recurrente o crónico

Background: Oral anticoagulation in non-valvular atrial fibrillation is associated with an increased risk of bleeding, particularly gastrointestinal bleeding, leading to treatment withdrawal in up to 50% of patients and putting them at risk of embolic events. Left atrial appendage closure (LAAC) can be an alternative to chronic anticoagulation. We aim to describe the impact of LAAC in patients with gastrointestinal bleeding (GIB) or chronic iron deficiency anaemia (CIDA) on healthcare resources consumption. Methods: Observational retrospective study of patients who underwent LAAC for GIB or CIDA at a single centre. Results: Nineteen patients with a median age of 74 years and a median Charlson score of six points were included in the study. Angiodysplasias were the most frequent cause of GIB or CIDA. The procedural success rate of LAAC was 100% with a median anticoagulant and antiplatelet treatment duration of 92 days. One year after the LAAC, we found a significant improvement in the lowest haemoglobin concentration and a reduction in the number of red blood cells transfusion, hospital admissions due to GIB and CIDA and the number of endoscopic examinations. One patient died due to a pulmonary thromboembolism. No deaths related to GIB were observed. Conclusions: LAAC seems to be a safe and effective alternative to anticoagulation in patients with GIB or CIDA. (AU)

Introducción: La anticoagulación oral en la fibrilación auricular no valvular se asocia a un incremento del riesgo de sangrado, especialmente gastrointestinal, lo que conlleva la retirada del tratamiento hasta en el 50% de los pacientes e implica un mayor riesgo de padecer un evento embólico. El cierre de la orejuela izquierda (COI) puede ser una alternativa a la anticoagulación crónica. Nuestro objetivo es describir el impacto del COI en pacientes con sangrado gastrointestinal (SGI) o anemia crónica ferropénica (ACF) en el consumo de recursos sanitarios. Métodos: Estudio observacional retrospectivo de pacientes sometidos a COI por SGI o ACF. Resultados: Diecinueve pacientes con una mediana de edad de 74años y una mediana del índice de Charlson de 6puntos fueron incluidos en el estudio. Las angiodisplasias fueron la causa más frecuente de SGI o ACF. La tasa de éxito técnico del COI fue del 100%, con una duración mediana del tratamiento anticoagulante y antiagregante de 92días. Tras un año del COI, se observó una mejoría significativa del valor mínimo de hemoglobina, así como una reducción en el número de transfusiones de concentrados de hematíes, en la necesidad de hospitalización por SGI o ACF y en el número de endoscopias. Un paciente falleció debido a un tromboembolismo pulmonar. Ningún paciente falleció por SGI. Conclusiones: El COI parece una alternativa segura y efectiva a la anticoagulación en pacientes con SGI o ACF. (AU)

Lesión de Dieulafoy, ¿y eso qué es? / Dieulafoy lesion, what is this?

El sangrado gastrointestinal es un motivo de consulta frecuente, tanto en los servicios de urgencias hospitalarios como en Atención Primaria. Existen múltiples etiologías que lo pueden motivar. La lesión de Dieulafoy es una causa rara pero potencialmente grave de hemorragia digestiva. Su localización más frecuente es el estómago. Clínicamente se expresa en forma de: melena, hematemesis o hematoquecia. Para su diagnóstico se pueden utilizar diversas exploraciones complementarias, como la angiografía, el angio-TC o la endoscopia. El tratamiento en casos recurrentes consiste en realizar embolización a través de un cateterismo intervencionista (AU)

Gastrointestinal bleeding is a common reason for consultation, both in hospital emergency services and in Primary Care. There are multiple etiologies that can motivate it. Dieulafoy's lesion is a rare but potentially serious cause of gastrointestinal bleeding. Its most common location is the stomach. Clinically it is expressed in the form of: melena, hematemesis or hematochezia. Various complementary exams can be used for its diagnosis, such as angiography, angio-CT or endoscopy. Recurrent bleeding treatment consists of embolization through interventional catheterization. (AU)

Impact of intense physical activity in athletes on intestinal mucosal integrity and its role in acute gastric hemorrhage and postoperative infection risks

In the context of rising gastric disease prevalence, acute gastric hemorrhage presents a significant clinical challenge, particularly among athletes who engage in intense physical activity. This demographic may have unique vulnerabilities due to the stress and strain of their rigorous training and performance routines. Acute gastric bleeding can arise from various sources, including gastritis from Helicobacter pylori infection, gastric ulcers, or vascular abnormalities exacerbated by lifestyle factors like excessive alcohol consumption. However, the impact of high-intensity physical exertion, common in athletes, on these conditions remains underexplored. In athletes, the management of acute gastric bleeding often involves conservative drug therapy post-hemodilation, with proton pump inhibitors like omeprazole offering both anti-inflammatory and acid-inhibiting effects. Surgical intervention is reserved for severe cases, considering the heightened risk of postoperative abdominal infections due to the stomach's unique physiology and its microbial population. This study focuses on the intestinal mucosal barrier's function postoperatively in athletes who have undergone treatment for acute gastric bleeding. We explore how intense physical activity influences intestinal mucosal integrity and its subsequent role in postoperative infection risks. The role of high-mobility group box1 (HMGB1) and the receptor for advanced glycation end products (RAGE) in this context is also examined. HMGB1, a crucial pro-inflammatory cytokine and late inflammatory mediator, and RAGE, a significant HMGB1 receptor, are believed to play pivotal roles in the inflammatory response following acute gastric bleeding (AU)

Encuesta internacional on-line sobre el manejo de la hemorragia digestiva baja grave. ¿Lo tenemos claro? / International on-line questionnaire about severe lower gastrointestinal bleeding management: Do we have it clear?

Introducción: La estrategia diagnóstico-terapéutica en la hemorragia digestiva baja (HDB) grave varía según la situación clínica del paciente. Las guías de práctica clínica actuales proponen diferentes estrategias de manejo. Objetivo: Conocer la toma de decisiones de los gastroenterólogos de distintos centros hospitalarios en el manejo de esta enfermedad. Métodos: Estudio observacional descriptivo mediante una encuesta on-line, dirigida a facultativos de aparato digestivo de España y Latinoamérica, en diciembre de 2021. Resultados: Se incluyeron 281 encuestas anónimas de facultativos de España y Latinoamérica. El manejo diagnóstico-terapéutico de la HDB grave fue heterogéneo entre los encuestados. Con respecto a los estudios iniciales mostraron variabilidad entre la solicitud de angiografía por tomografía computarizada (angio-TC) (44,5%), gastroscopia (33,1%), colonoscopia (20,6%) y arteriografía (1,1%). La decisión terapéutica tras angio-TC positiva variaba mayoritariamente entre la solicitud de arteriografía (38,1%) y colonoscopia (44,1%). Si la angio-TC era negativa se realizaba gastroscopia en la mayoría de los casos. Si el paciente ingresaba en una unidad de cuidados intensivos y precisaba colonoscopia, la mayor parte de los encuestados la realizaban urgente (<24h) (31% siempre, 43,4% en la mayoría de los casos); mientras que, si no requerían ingreso en intensivos este porcentaje se reducía (10% siempre, 33,8% en la mayoría de los casos). Reconocían tener dudas en el manejo de estos pacientes el 40,9% de los encuestados, y consideraban necesario la creación de un protocolo de actuación el 98,2% de los participantes. Conclusiones: Existe una gran variabilidad interhospitalaria en el manejo de la HDB grave entre los gastroenterólogos. Es necesario unificar la actuación diagnóstico-terapéutica en esta enfermedad.(AU)

Background and aims: The diagnostic and therapeutic strategy in severe lower gastrointestinal bleeding (LGIB) varies depending on the patient's clinical situation. Actual clinical practice guidelines propose different management strategies. We aim to know the attitude of the gastroenterologists from different hospitalary centers in the management of this entity. Methods: Descriptive and observational study using an on-line questionnaire, addressed to gastroenterologists in Spain and Latin America, in December 2021. Results: We included 281 anonymous questionnaires of gastroenterologists from Spain and Latin America. Diagnostic and therapeutic management of severe LGIB was heterogeneous among the participants. Regarding to the first diagnostic modalities they showed variability between performing computed tomography angiography (CTA) (44.5%), gastroscopy (33.1%), colonoscopy (20.6%) and arteriography (1.1%). The therapeutic attitude after a positive CTA mostly varied between performing arteriography (38.1%) and colonoscopy (44.1%). If negative CTA, in the majority of cases a gastroscopy was performed. If the patient needed intensive critical unit (ICU) care and to undergo colonoscopy, most participants performed an urgent colonoscopy (<24h) (31% always, 43.4% in most cases); while if the patient did not require ICU admission this percentage was lower (10% always, 33.8% in most cases). The 40.9% of the participants admitted having doubts about the management of this patients and the 98.2% considered the need for a creation of an action protocol. Conclusions: There is a high interhospitalary variability on the management of severe lower gastrointestinal bleeding among gastroenterologists. It is necessary to unify the diagnostic and therapeutic management of this pathology.(AU)

Comparison of urgent and early endoscopy for acute non-variceal upper gastrointestinal bleeding in high-risk patients / Comparación entre endoscopia urgente y temprana para hemorragia digestiva alta no varicosa en pacientes de alto riesgo

Objective: Data regarding early (within 24h) and urgent endoscopy (within 12h) in non-variceal upper gastrointestinal bleeding (NV-UGIB) revealed conflicting results. This study aimed to investigate the impact of endoscopy timing on the outcomes of high-risk patients with NV-UGIB. Patients and methods: From February 2020 to February 2021, consecutive high-risk (Glasgow–Blatchford score ≥12) adults admitted to the emergency department with NV-UGIB were analyzed retrospectively. The primary composite outcome was 30-day mortality from any cause, inpatient rebleeding, need for endoscopic re-intervention, need for surgery or angiographic embolization. Results: 240 patients were enrolled: 152 (63%) patients underwent urgent endoscopy (<12h) and 88 (37%) patients underwent early endoscopy (12–24h). One or more components of the composite outcome were observed in 53 (22.1%) patients: 30 (12.5%) had 30-day mortality, rebleeding occurred in 27 (11.3%), 7 (2.9%) underwent endoscopic re-intervention, and 5 (2.1%) required surgery or angiographic embolization. The composite outcome was similar between the groups. Multivariate analysis showed only hemodynamic instability on admission (OR: 3.05, p=0.006), and the previous history of cancer (OR: 2.42, p=0.029) were significant in predicting composite outcome. In terms of secondary outcomes, the endoscopic intervention was higher in the urgent endoscopy group (p=0.006), whereas the number of transfused erythrocyte suspensions and the length of hospital stay was higher in the early endoscopy group (p=0.002 and p=0.040, respectively). Conclusions: Urgent endoscopy leads to a significant reduction in the length of hospitalization and the number of transfused erythrocyte suspensions in NV-UGIB, which can contribute to patient satisfaction, reduce healthcare expenditure, and improve hospital bed availability. The composite outcome and its sub-outcomes were the same among both groups.(AU)

Objetivo: Los datos en relación con la endoscopia temprana (dentro de las 24h) y urgente (dentro de las 12horas) en la hemorragia digestiva alta no varicosa (HDA-NV) mostraron resultados contradictorios. El objetivo del estudio fue investigar el impacto del momento de la endoscopia en el desenlace de los pacientes de alto riesgo con HDA-NV. Pacientes y métodos: Se realizó un análisis retrospectivo de adultos con HDA-NV consecutivos de alto riesgo (puntuación de Glasgow-Blatchford≥12) ingresados en el servicio de urgencias entre febrero de 2020 y febrero de 2021. El principal resultado compuesto fue mortalidad a los 30días por cualquier causa, nueva hemorragia de pacientes hospitalizados, necesidad de una nueva intervención endoscópica o necesidad de cirugía o embolización angiográfica. Resultados: Se incluyeron 240 pacientes: 152 (63%) se sometieron a endoscopia urgente (<12h) y 88 (37%) a endoscopia temprana (12-24h). Se observaron uno o más de los elementos del resultado compuesto en 53 (22,1%) pacientes: 30 (12,5%) tuvieron mortalidad a los 30 días, se produjo nuevo sangrado en 27 (11,3%), 7 (2,9%) se sometieron a una nueva intervención endoscópica y 5 (2,1%) requirieron cirugía o embolización angiográfica. El resultado compuesto fue similar entre los grupos. El análisis multivariado mostró que solamente la inestabilidad hemodinámica al ingreso (OR: 3,05, p=0,006) y la historia previa de cáncer (OR: 2,42, p=0,029) fueron significativos para predecir el resultado compuesto. En relación con los resultados secundarios, la intervención endoscópica fue más frecuente en el grupo de endoscopia urgente (p=0,006), mientras que el número de transfusiones de suspensiones eritrocíticas y la duración de la estancia hospitalaria fueron mayores en el grupo de endoscopia temprana (p=0,002 y p=0,040, respectivamente). Conclusiones: La endoscopia urgente conduce a una reducción significativa en el tiempo de hospitalización y en el número...(AU)
