Massive LGIB is a life-threatening condition in which patients present with a systolic blood pressure (SBP) below 90 mm Hg and a hemoglobin (Hb) level of 6 g/dL or less. Affected patients are usually aged 65 years and older, have multiple medical problems, and are at risk of death from acute hemorrhage or its complications. The passage of maroon stools or bright red blood from the rectum is usually indicative of massive lower GI hemorrhage.
