The lower gastrointestinal (LGI) tract includes the small bowel distal to the ligament of Treitz and the colon, rectum, and anus. In children and adolescents, the differential diagnosis of LGI bleeding includes juvenile polyps, inflammatory bowel disease, intussusception, and Meckel’s diverticulum. In adults, the common causes include angiodysplasia, diverticulosis, neoplasm, inflammatory bowel disease, and anorectal sources such as hemorrhoids and fissures. “Hemorrhage” implies rapid bleeding often accompanied by hemodynamic instability.
