Lower Gastrointestinal Bleeding



Lower GI hemorrhage is defined as bleeding that occurs from the bowel distal to the ligament of Treitz. Majority of patients with hematochezia bleed from the large bowel, but in 10-25% of patients, the small bowel is the source of bleeding, and it poses difficult diagnostic dilemma. Also, some patients with massive upper GI bleeding can present with hematochezia. Lower GI bleeding represents a diverse range of bleeding sources and severities, ranging from mild hemorrhoidal bleeding to massive blood loss from vascular small bowel tumors.
