It is difficult to predict which patients are going to need urgent surgery in severe acute LGIB; only the presence of hypotension on arrival at the emergency ward would lead us to suspect a negative outcome for the hemorrhage. In severe acute LGIB, morbidity and mortality is high, and this is mainly due to the high level of associated comorbidity and the need for urgent surgery. It is necessary for strict hemodynamic monitoring of the patients at risk if we want to improve outcomes. The bleeding relapse rate is high in LGIB, although generally, it is not severe.
