Lower gastrointestinal bleeding (LGIB) originates distal to the ligament of Treitz, mainly involving the colon, rectum, and anus. Presenting as either acute, overt bleeding (e.g., hematochezia) or chronic, occult bleeding, LGIB is a significant cause of hospitalization, with rising morbidity and mortality rates, particularly among elderly and comorbid patients. Common causes include diverticular disease, angioectasias, hemorrhoids, and ischemic colitis. Effective management aims to stabilize the patient, identify the bleeding source, and provide targeted medical, endoscopic, or surgical interventions [1] [Algorithm 39.1].
