ABSTRACT

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.

ABSTRACT

RESUMEN Antecedentes: la pandemia por COVID-19 generó importantes cambios en la atención y tratamiento de los pacientes quirúrgicos. Objetivo: los objetivos de este estudio fueron comparar los volúmenes de prestaciones realizadas durante un año de pandemia con un período igual sin pandemia, proyectar su impacto asistencial e institucional, y comparar pacientes COVID+ versus COVID- para determinar complicaciones posoperatorias, mortalidad y los factores de riesgo asociados a estos eventos. Material y métodos: estudio observacional y retrospectivo. Comparamos el volumen de prestaciones realizadas entre el 19/3/20 y el 18/3/21 con idéntico período de 2019/20. Efectuamos un estudio de cohorte emparejada (2:1) entre los pacientes con COVID-19 y sin él y se analizaron las complicaciones posoperatorias, la mortalidad, y doce variables objetivas como factores de riesgo asociados. Resultados: todas las variables prestacionales analizadas disminuyeron, pero solo las internaciones programadas y las cirugías y endoscopias no urgentes cayeron significativamente. De los 979 ingresos, 41 casos fueron COVID+ (4,1%). La mortalidad fue del 29,2% en COVID+ (12/41) vs. 7,3% en COVID- (6/82) P = 0,021. Los factores de riesgo significativos asociados a mortalidad fueron: edad ≥ 75 años, hombres, COVID+, urgencias, neumonía, requerimiento de UTI y ARM. Los pacientes operados presentaron una tasa significativamente mayor de neumonías. El análisis de regresión logística (COVID+ vs. -) mostró que por ser COVID+ y registrar la necesidad de ARM, como variables determinantes, en los COVID+ solo la ARM fue determinante en la mortalidad. Conclusión: la pandemia por COVID-19 disminuyó la actividad prestacional y aumentó la mortalidad de los afectados por la virosis.


ABSTRACT Background: The COVID-19 pandemic produced significant changes in the care and treatment of surgical patients. Objectives: The aims of this study were to compare the volume of services provided during a year of pandemic with an equal period without pandemic, estimate its impact on health care and institutional care, and compare COVID-positive versus COVID-negative patients to determine postoperative complications, mortality and risk factors associated with these events. Material and methods: We conducted an observational and retrospective study, comparing the volume of services performed between March 19, 2020, and March 18, 2021, with the same period in 2019/2020. We performed a matched cohort study (in a 2:1 ratio) between patients with and without COVID-19 and analyzed the postoperative complications, mortality, and twelve objective variables as associated risk factors. Results: There was a significant decrease in planned hospitalizations and non-urgent surgeries and endoscopies, while all the other variables showed a non-significant reduction. Of the 979 admissions, 41 corresponded to COVID-positive patients (4.1%). Mortality was 29.2% in COVID-positive patients (12/41) vs. 7.3%% in those COVID negative (p = 0.021). The significant risk factors associated with mortality were age ≥75 years, male sex, COVID+, emergencies, pneumonia, requirement of ICU and MV. Patients operated on had a significantly higher rate of pneumonia. Logistic regression analysis between COVID+ patients and COVID- patients showed that COVID+ and need for MV were predictors of mortality. In COVID+ patients, only MV was a determinant of mortality. Conclusion: The COVID-19 pandemic reduced healthcare services and increased mortality in patients infected with the virus.
