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).
