Acute Lower Gastrointestinal Bleeding: Evaluation and Management.
Evaluation and management of acute lower gastrointestinal bleeding focus on etiologies originating distally to the ligament of Treitz. Diverticular disease is the most common source, accounting for 40% of cases. Hemorrhoids, angiodysplasia, infectious colitis, and inflammatory bowel disease are other common sources. ⋯ Surgical intervention should be considered only for patients with uncontrolled severe bleeding or multiple ineffective nonsurgical treatment attempts. Percutaneous catheter embolization should be considered for patients who are poor surgical candidates. Treatment is based on the identified source of bleeding.
