RESUMEN
Gastrointestinal hemorrhage is one of the most frequent complications that occurs in 15 20% patients with peptic ulcer disease. Recurrent ulcer haemorrhage presents in the first 72 hours after initial bleeding: they are the most im portant cause of death. The aim of our study was to show the possibility of ulcer recurrent haemorrhage combined with risk factors: age 60, high risk lesion (active arterial bleeding, visible blood vessel, adherent coagulum), the size, ulcer base and localization (posterior duodenal wall. lesser curvature or high gastric ulcer), commorbidities ( cardiovascular and liver diseases) and haemodynamic instabilities. The combination of these risk-factor, unproportionally increases the risk: presence of two risk factors gives the possibility of recurrent bleeding of 16.67%, three risk factors 58.82%, four 93.33%, while the presence of five risk factors shows 100% posibility. Probability of death is 8.27 times greater if ulcer haemorrhage occurs.
