ABSTRACT

INTRODUCCIÓN: El presente estudio pretende validar el score de Rockall en nuestro medio y encontrar el valor que mejor discrimine entre el paciente con alto y bajo riesgo de mortalidad, resangrado y necesidad de transfusión de más de 2 paquetes globulares en pacientes con hemorragia digestiva alta.MATERIAL Y MÉTODOS: Se realizó un estudio descriptivo, prospectivo en pacientes que acudieron a la emergencia del Hospital Nacional Cayetano Heredia entre febrero del 2007 y enero del 2008 por presentar hemorragia digestiva alta (melena, hematemesis, vómito tipo bona de café, rectorragia o hematoquezia), se utilizó el score de Rockall para determinar su severidad y estratificar a los pacientes con mayor riesgo de fallecer o presentar resangrado. Para el estudio se entrevistó al paciente, se recolectaron datos de las historias clínicas, de los informes endoscópicos en emergencia y en los pisos de hospitalización, se evaluó en el seguimiento la ocurrencia de resangrado, el número de paquetes globulares transfundidos y la mortalidad.RESULTADOS: En total fueron 163 pacientes los incluidos en el estudio, 107 (65.64 por ciento) casos fueron varones y 56 (34.36 por ciento) mujeres, pero se debió excluir a 8 de ellos porque no contaban con endoscopía de emergencia. Entre los 155 restantes se buscó establecer el punto de corte para determinar a los pacientes severos y no severos utilizando la curva de ROC (Receiver Operating Characteristic). Luego del análisis, se encontró que al comparar el Score de Rockall con la mortalidad (12.9 por ciento), los pacientes con un score mayor igual de 5 presentaban más riesgo de fallecer que los pacientes con puntaje menor, con un área bajo la curva de ROC de 0.8037 que indica una alta capacidad de discriminación de este score para predecir mortalidad...


INTRODUCTION: The present study intends to validate the Rockall Score in patients with upper gastrointestinal bleeding (UGB) in our current medical setting and to find the value that best discriminates between patients with high or low risk of mortality, rebleeding and the need of more than two units of packed red blood cells (PRBC). MATERIALS AND METHODS: A descriptive prospective study was made from patients who arrived to Cayetano Heredia Hospital¢¥s emergency department between February 2007 and January 2008 due to UGB symptoms (hematemesis, coffe ground remit melena or hematoquezia). The Rockall score was used to determine severity of UGB and to stratify patients with higher risk of mortality or rebleeding. All patients were interviewed and any additional information was gathered from medical history records and emergency and hospitalization endoscopic procedure reports. During the study all patients were evaluated for rebleeding, the number of units of PRBCs needed and mortality rate.RESULTS: 163 patients were included in our study, 107 (65.64 percent) were male and 56 (34.36 percent) female, 8 were excluded due to lack of an endoscopic procedure. The remaining 155 patients were studied to evaluate the discriminative ability of the scoring system, and to determine which value best distinguishes high and low severity patients using Receiver Operating Characteristic curve (ROC) and calculated area under the curve. The data analysis showed patients with a Rockall Score ¡Ã 5 had an increased mortality rate compared to lower score with an area under the curve of 0.807, meaning an accurate relationship between mortality and a score ¡Ã 5. For rebleeding and the need of two packed red blood cells for transfusion, the area under the curve were 0.65 and 0.64 respectively showing a low predictive value...
