Diagnostic accuracy of the Oakland score versus haemoglobin for predicting outcomes in lower gastrointestinal bleeding.

BACKGROUND: Acute lower gastrointestinal bleeding (ALGIB) is a common cause of hospitalization. Recent guidelines recommend the use of prognostic scales for risk stratification. However, it remains unclear whether risk scores are more accurate than some simpler prognostic variables. OBJECTIVE: To compare the predictive values of haemoglobin alone and the Oakland score for predicting outcomes in ALGIB patients. DESIGN: Single-centre, retrospective study at a University Hospital. Data were extracted from the hospital's clinical records. The Oakland score was calculated at admission. Study outcomes were defined according to the original article describing the Oakland score: safe discharge (the primary Oakland score outcome), transfusion, rebleeding, readmission, therapeutic intervention and death. Area under the receiver operating characteristics (AUROC) curve and accuracy using haemoglobin and the Oakland score were calculated for each outcome. RESULTS: Two hundred and fifty-eight patients were included. Eighty-four (32.6%) needed transfusion, 50 (19.4%) presented rebleeding, 31 (12.1%) required therapeutic intervention, 20 (7.8%) were readmitted and six (2.3%) died. There were no differences in the AUROC curve values for haemoglobin versus the Oakland score with regard to safe discharge (0.82 (0.77-0.88) vs 0.80 (0.74-0.86), respectively) or to therapeutic intervention and death. Haemoglobin was significantly better for predicting transfusion and rebleeding, and the Oakland score was significantly better for predicting readmission. CONCLUSION: In our study, the Oakland score did not perform better than haemoglobin alone for predicting the outcome of patients with ALGIB. The usefulness of risk scores for predicting outcomes in clinical practice remains uncertain.

Hemorragia digestiva alta / Upper Gastrointestinal Bleeding

Introducción: La hemorragia digestiva alta tiene una elevada morbimortalidad. La endoscopía digestiva alta es el estudio de elección para su diagnóstico y tratamiento. Objetivo: Describir la conducta ante la hemorragia digestiva alta. Métodos: Para la revisión bibliográfica se consultaron artículos científicos indexados en idioma español e inglés, relacionados con la hemorragia digestiva, publicados en las bases de datos PubMed, SciELO, Medline y Cochrane, pertenecientes a autores dedicados al estudio de este tema. Desarrollo: La hemorragia digestiva alta se clasifica, según la etiología de origen, en variceal y no variceal. La mayoría de los pacientes con hemorragia digestiva alta el sangrado se autolimita. La causa más habitual es la úlcera péptica, pero en caso de sangrado masivo la etiología más frecuente es la variceal. El empleo precoz de la terlipresina en los pacientes con hemorragia digestiva alta variceal mejora el control del sangrado y disminuye la mortalidad. Se debe hacer uso de escalas validadas de estratificación del riesgo: escala de riesgo de Rockall (tiene como propósito principal predecir la mortalidad y riesgo de resangrado del paciente) y la escala de Glasgow-Blatchford). Conclusiones: Sospechar la presencia de hemorragia digestiva alta, estratificar su riesgo e instaurar el manejo inicial y apropiado constituye una prioridad para el médico de urgencia(AU)

Introduction: Upper gastrointestinal bleeding presents high morbidity and mortality. Upper gastrointestinal endoscopy is the study of choice for its diagnosis and treatment. Objective: To describe the management of upper gastrointestinal bleeding. Methods: For the bibliographic review, the consultation was carried out of scientific articles indexed in Spanish and English, related to gastrointestinal bleeding, published in the databases PubMed, SciELO, Medline and Cochrane, belonging to authors dedicated to the study of this subject. Development: Upper gastrointestinal bleeding is classified, according to the etiology of origin, into variceal and nonvariceal. In most patients with upper gastrointestinal bleeding the bleeding as such is self-limiting. The most common cause is peptic ulcer; however, in the case of massive bleeding, the most frequent etiology is variceal. Early use of terlipressin in patients with variceal upper gastrointestinal bleeding improves bleeding control and decreases mortality. Validated risk stratification scales should be used: Rockall risk scale (its main purpose is to predict patient mortality and risk of bleeding recurrence) and the Glasgow-Blatchford scale. Conclusions: Suspecting the presence of upper gastrointestinal bleeding, stratifying its risk, as well as instituting initial and appropriate management, are a priority for the emergency physician(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)

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)

Aortoenteric fistulae and their multidisciplinary approach.

Aortoenteric fistula is an uncommun life-threatening condition which remains associated with significant morbidity and mortality. It can be primary (aneurysm, neoplasms, radiation therapy, infection) or secondary to vascular prosthesis. Early diagnosis and aggressive surgical treatment are very important to achieve optimal outcomes in these patients. The aim of this article is to highlight the importance of early diagnosis and multidisciplinary approach of aortoenteric fistula through the presentation of a clinical case.

La fístula aortoentérica es una patología poco frecuente, pero de riesgo vital, asociada a alta morbimortalidad. Puede ser primaria (aneurisma, neoplasia, radioterapia, infección) o secundaria a prótesis vascular. El diagnóstico precoz y el tratamiento quirúrgico agresivo son los pilares fundamentales para lograr buenos resultados en estos pacientes. El objetivo de este trabajo es destacar la importancia del diagnóstico precoz de la fístula aortoentérica y su manejo multidisciplinar, mediante la presentación de un caso clínico.

Fatores preditivos de morbidade associada à sangramento de varizes esofágicas em crianças com hipertensão porta / Predictive factors of morbidity associated with esophageal variceal bleeding in children with portal hypertension

ABSTRACT Background: Most data on the natural history of portal hypertension come from studies in adults. The morbidity rate of upper gastrointestinal bleeding (UGIB) in children with portal hypertension has not been systematically characterized. Objective: To describe the morbidity and mortality of UGIB in pediatric patients with portal hypertension and identify predictive factors for the occurrence of its main complications. Methods: This retrospective study included pediatric patients with cirrhotic portal hypertension or with extrahepatic portal vein obstruction (EHPVO). Mortality and UGIB complications within a period of up to 6 weeks of the bleeding were investigated. To determine the predictive factors of morbidity, a multivariate analysis was performed using logistic regression; all results were considered significant at P<0.05. Results: A total of 86 patients (51.2% with EHPVO and 48.8% with cirrhosis) had 174 bleeding events. Ascites was the most common complication (43.1% of all cases), being more prevalent in patients with cirrhosis (P<0.001). Cirrhosis was a predictor of the occurrence of any morbidity (OR 20.3). The need for blood transfusion was predictor of at least one complication (OR 5.8), ascites (OR 7.2) and infections (OR 3.8) in the general group and at least one complication (OR 11.3) and ascites (OR 5.8) in cirrhotic patients. The need for expansion was a predictor of any morbidity (OR 4.6) and infections (OR 3.9) in the general group, in addition to being predictor of infection in cirrhotic patients (OR 5.4). There were no deaths from UGIB in the six weeks post-bleeding. Conclusion: The study showed the relevance of morbidity after UGIB in pediatric patients with portal hypertension, especially in those with cirrhosis. The patients with hemodynamic instability requiring blood transfusion or expansion on admission are at increased risk of complications related to upper gastrointestinal bleeding and should be closely monitored.

RESUMO Contexto: A maioria dos dados sobre a história natural da hipertensão porta provém de estudos em adultos. A morbidade associada à hemorragia digestiva alta (HDA) em crianças com hipertensão porta ainda não foi sistematicamente estudada. Objetivo: Descrever a morbimortalidade da HDA em pacientes pediátricos com hipertensão porta e identificar fatores preditivos para a ocorrência de suas principais complicações. Métodos: Este estudo retrospectivo incluiu pacientes pediátricos com hipertensão porta cirrótica ou com obstrução extra-hepática da veia porta (OEHVP). A mortalidade e as complicações da HDA foram estudadas até seis semanas após o sangramento. Para determinar os fatores preditivos de morbidade, foi realizada análise multivariada por meio de regressão logística; todos os resultados foram considerados significativos com P<0,05. Resultados: Oitenta e seis pacientes (51,2% com OEHVP e 48,8% com cirrose) tiveram 174 eventos hemorrágicos. A ascite foi a complicação mais comum (43,1% de todos os casos), sendo mais prevalente em pacientes com cirrose (P<0,001). A cirrose foi preditor da ocorrência de pelo menos uma complicação (OR 20,3). A necessidade de transfusão sanguínea foi preditora de pelo menos uma complicação (OR 5,8), ascite (OR 7,2) e infecções (OR 3,8) no grupo geral e pelo menos uma complicação (OR 11,3) e ascite (OR 5,8) nos cirróticos. A necessidade de expansão foi preditor de qualquer morbidade (OR 4,6) e infecções (OR 3,9) no grupo geral, além de ser preditor de infecção em cirróticos (OR 5,4). Não houve óbitos por HDA nas 6 semanas pós-sangramento. Conclusão: O estudo mostrou a relevância da morbidade após HDA em pacientes pediátricos com hipertensão porta, principalmente naqueles com cirrose. Os pacientes com instabilidade hemodinâmica que necessitam de transfusão de sangue ou expansão na admissão têm risco aumentado de complicações relacionadas à hemorragia digestiva alta e devem ser monitorados de perto.

Hemorragia digestiva baja: factores de riesgo de gravedad, necesidad de cirugía de urgencia y mortalidad hospitalaria / Lower gastrointestinal bleeding: risk factors of severity, need for emergency surgery and in-hospital Mortality

RESUMEN Antecedentes: Últimamente creció el interés en poder determinar, en etapas tempranas de las hemorragias digestivas bajas (HDB), aquellos factores de riesgo relacionados con la posibilidad de presentar resultados evolutivos adversos. Objectivo: Determinar los factores de riesgo asociados a sangrados graves, cirugía de urgencia y mortalidad hospitalaria. Material y métodos: Realizamos un estudio observacional y retrospectivo sobre 1.850 pacientes, atendidos en forma consecutiva entre enero de 1999 y diciembre de 2018 por HDB. Para evaluar el riesgo de gravedad analizamos trece variables en las primeras cuatro horas desde la admisión. Para determinar los factores relacionados con la cirugía de urgencia, agregamos la enfermedad diverticular y, para evaluar mortalidad, la cirugía de urgencia y el puntaje (score) preoperatorio de la Sociedad Americana de Anestesiología (ASA). Resultados: De los 1.850 casos, 194 fueron graves y 1656 leves/moderados. Resultaron estadísticamente significativos como factores de mayor gravedad: > 70 años, FC > 120 lat/min., TA < 90 mm Hg, oliguria, hematoquecia masiva, hematocrito < 30%, hemoglobina < 7 g/% y necesidad transfusional. Resultaron predictores significativos de cirugía de urgencia: > 70 años, anti-coagulación, hipotensión arterial, taquicardia, hemoglobina < 7 g/%, oliguria, transfusiones y hematoquecia masiva. Se construyó una fórmula pronóstica de requerimiento de cirugía (sensibilidad 94%, especificidad 74%, valor predictivo positivo 91% y valor predictivo negativo 81%). AUC: 0,89%. Fueron significativos para mortalidad: > 70 años, anticoagulados, hematoquecia masiva, transfusiones y cirugía urgente. De los dieciséis pacientes operados y fallecidos de la serie, quince presentaban un ASA ≥ IV. Conclusiones: Las variables utilizadas resultaron simples, fiables y estadísticamente significativas para predecir gravedad, cirugía de urgencia y mortalidad.

ABSTRACT Background: Background: There has been a growing interest in determining those risk factors associated with adverse outcomes in early stages of lower gastrointestinal bleeding (LGIB). Objective: The aim of our study was to analyze the risk factors associated with severe bleeding, emergency surgery and in-hospital mortality. Material and methods: We conducted an observational and retrospective study on 1850 patients consecutive managed between January 1999 and December 2018 for LGIB. We analyzed thirteen variables within the first four hours of hospitalization to evaluate risk severity. Diverticular disease was considered to determine factors associated with emergency surgery, and the preoperative American Society of Anesthesiologists (ASA) score was used to assess mortality and emergency surgery. Results: Out of 1850 cases, 194 were severe and 1656 were mild/moderate, Patients > 70 years, with HR > 120 beats/min, BP < 90 mm Hg, oliguria, massive hematochezia, hematocrit < 30%, hemoglobin < 7 g% and need for transfusions presented statistically significant associations with severe bleeding. Age > 70 years, anticoagulation, hypotension, tachycardia, hemoglobin < 7 g%, oliguria, need for transfusion and massive hematochezia were significant predictors of emergency surgery. A prognostic formula was constructed to predict the need for surgery (sensitivity 94%, specificity 74%, positive predictive value 91% and negative predictive value 81%). AUC-ROC: 0,89%. Age > 70 years, anticoagulation, massive hematochezia transfusions and emergency surgery were identified as predictors of mortality. Fifteen of the sixteen patients who underwent surgery and died had ASA ≥ grade 4. Conclusions: The variables analyzed are simple, reliable and statistically significant to estimate the risk of severe bleeding, need for emergency surgery and mortality.

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)

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

Hemorragia digestiva alta grave por fistula entre arteria esplénica y manga gástrica / Severe upper gastrointestinal bleeding due to fistula between splenic artery and gastric sleeve / Hemorragia digestiva alta grave devido a fístula entre artéria esplênica e manga gástrica

La hemorragia digestiva determinada por una fístula entre manga gástrica y seudoaneurisma de arteria esplénica o polo superior de bazo es infrecuente. Se presenta un caso clínico de una paciente de 52 años con antecedentes de cirugía de manga gástrica y fuga anastomótica. Ingresó por hemorragia digestiva alta grave. Se operó de emergencia y realizó punto hemostático sobre cara posterior de manga gástrica. Se reintervino por resangrado realizándose la gastrectomía y esplenopancreatectomía distal por solución de continuidad de arteria esplénica. Dada la inestabilidad hemodinámica se efectuó un esofagostoma y yeyunostomía, reconstruyéndose a los 8 meses con buena evolución.

Gastrointestinal bleeding caused by a fistula between the gastric sleeve and a pseudoaneurysm of the splenic artery or upper pole of the spleen is uncommon. A clinical case of a 52-year-old patient with a history of gastric sleeve surgery and anastomotic leak is presented. She was admitted for severe upper gastrointestinal bleeding. She underwent emergency surgery and performed a hemostatic stitch on the posterior face of the gastric sleeve. She underwent reoperation due to rebleeding, performing gastrectomy and distal splenopancreatectomy due to discontinuation of the splenic artery. Given the hemodynamic instability, an esophagostomy and jejunostomy were performed, reconstructing at 8 months with good evolution.

O sangramento gastrointestinal causado por uma fístula entre a manga gástrica e um pseudoaneurisma da artéria esplênica ou pólo superior do baço é incomum. Apresenta-se o caso clínico de um paciente de 52 anos com história de cirurgia de manga gástrica e fístula anastomótica. Ele foi internado por hemorragia digestiva alta grave. Uma operação de emergência foi realizada e um ponto hemostático foi realizado na face posterior da manga gástrica. Foi reoperado por ressangramento, realizando gastrectomia e esplenopancreatectomia distal por descontinuação da artéria esplênica. Dada a instabilidade hemodinâmica, foi realizada esofagostomia e jejunostomia, reconstruindo aos 8 meses com boa evolução.

Variación estacional de la hemorragia digestiva alta / Seasonal variation of upper gastrointestinal bleeding

Introducción: La hemorragia digestiva alta representa una de las causas más frecuentes de morbilidad y mortalidad en los servicios de cirugía general y específicamente es la primera causa de mortalidad en el servicio, por lo que constituye una emergencia médico-quirúrgica. Objetivo: Identificar la existencia de un patrón estacional en la incidencia de hemorragia digestiva alta en época invernal y estimar la frecuencia de algunos factores de riesgo de esta enfermedad. Métodos: Se realizó un estudio descriptivo, de series temporales, de pacientes afectados por esa enfermedad que acudieron al Hospital Dr. Miguel Enríquez en el periodo comprendido entre diciembre de 2017 y enero de 2020. La muestra quedó conformada por 151 pacientes que presentaron como diagnóstico de ingreso hemorragia digestiva alta. Resultados: Predominó el sexo masculino y los mayores de 60 años. La temporada de mayor incidencia de esta complicación digestiva fue la invernal (diciembre, enero y febrero). Los factores de riesgo que predominaron fueron los hábitos tóxicos y la ingestión de AINES y ASA. La forma de presentación más frecuente fue la melena y la principal etiología la úlcera péptica duodenal. Conclusiones: Los casos con hemorragia digestiva alta predominaron en la temporada invernal y los factores de riesgo más frecuentes fueron los hábitos tóxicos y el uso de AINES en relación con el periodo estacional(AU)

Introduction: The High Digestive Hemorrhage represents one of the most frequent causes of morbidity and mortality in the General Surgery Services and it is specifically the first cause of mortality in our service. It constitutes a very frequent medical-surgical emergency. Objective: To determine the existence of a seasonal pattern in the incidence of HDA in winter and its relationship with risk factors. Methods: A descriptive and retrospective study was carried out with a longitudinal design in which patients affected by HDA were studied. These patients were assisted at "Dr. Miguel Enriquez Hospital" between December 2017 and January 2020. The study group was composed of all the patients who came to our emergency services with manifestations of bleeding from the upper digestive tract. The sample was made up of 151 patients who presented a diagnosis of HDA at the time of their admission. Results: The predominant sex was male and the age over 60 years old. The season with the highest incidence of this digestive complication was winter (December, January and February). The risk factors that predominated in our study were toxic habits and ingestion of AINES, ASA. The predominant form of presentation of the HDA were tarry stools, being the Duodenal Peptic Ulcer the main etiology. Conclusions: Cases with Upper Digestive Bleeding predominated in the winter season and the most frequent risk factors were toxic habits and the use of NSAIDs in relation to the seasonal period(AU)

Stress ulcer prophylaxis for critically ill children: routine use needs to be re-examined.

INTRODUCTION: Stress ulcer prophylaxis (SUP) is commonly used in Paediatric Intensive Care Units (PICUs). However, strong evidence for this practice is lacking and there is a dire need for paediatric randomized controlled trials (RCTs). Our aim was to assess the usefulness of SUP with omeprazole in critically ill children. PATIENTS AND METHODS: We conducted a randomized, controlled open-label trial, including 144 children admitted into a PICU with a paediatric Sequential Organ Failure Assessment (pSOFA) score of less than 16. We randomly allocated patients to SUP with omeprazole or no SUP. The primary outcome was development of upper gastrointestinal bleeding or nosocomial infection. RESULTS: The incidence of gastrointestinal bleeding was 27.1%, but clinically significant bleeding developed in only 5.6% of patients. We did not find a significant difference in the incidence of bleeding between the prophylaxis and control groups (27.8% vs 26.4%; P = .85). We also did not find a significant difference between the groups in the incidence of ventilator-associated pneumonia (VAP) (9.6% vs 8.3%; P = .77). The incidence of central line-associated bloodstream infection (CLABSI) was higher in the prophylaxis group compared to the control group (30.6% vs 12.5%; P = .014). None of the patients developed Clostridium difficile-associated diarrhoea. We did not find significant differences in mortality, length of PICU stay or duration of mechanical ventilation. Mechanical ventilation was an independent predictor of bleeding (OR, 6.4; 95%CI, 2.73-14.9). CONCLUSION: In PICU patients with mild to moderate organ dysfunction, omeprazole does not seem to be useful for prevention of gastrointestinal bleeding while at the same time increasing the risk of CLABSI. Thus, we recommend restricting SUP to mechanically ventilated children.
