    The gastrointestinal bleeding represents a common medical emergency, with considerable morbidity and mortality rates. That’s why the prompt diagnosis is essential for a better prognosis of these patients. Endoscopy is the main diagnostic tool in this context, however, when the gastrointestinal hemorrhage is massive, the bleeding site can be obscured during endoscopy; in addition, endoscopy is not always available and a trained professional might not be present. Bowel preparation is necessary for colonoscopy, which doesn’t evaluate the most part of small intestine. Scintigraphy does not allow precise anatomic localization of the bleeding and it’s unavailable in the emergency setting. The use of capsule endoscopy is inappropriate in the acute setting, particularly in the emergency department at night and it has high costs. Digital angiography is invasive, has risks associated with vascular access, besides little availability in the emergency setting. On the other hand, angiotomography (angio-CT) is fast, highly available and minimally invasive. It is a promising alternative in these patients algorithm, being capable to determine the localization and the cause of bleeding with high accuracy and to guide treatment. Basing in a critical literature review and our own experience, we propose an angio- CT’s protocol for the patient with gastrointestinal bleeding.
