PY - 2015 T2 - Maternal Medicine AB - The American College of Gastroenterology defines acute lower gastrointestinal bleeding (LGIB) as a bleeding episode from the gastrointestinal tract originating distal to the ligament of Treitz that may lead to unstable vital signs, anemia, or requirement of a blood transfusion.1 Acute LGIB most commonly presents as hematochezia and often necessitates hospital admission, immediate workup, and treatment. In this section, we will be focusing on the initial evaluation of acute hematochezia associated with inflammatory bowel disease (IBD), the major etiology of LGIB in the young adult population.
