    Lower GI Bleeding Accounts for 20% of all acute GI bleeding. That's a large percentage. The initial evaluation includes DRE, stands for Digital Rectal Examination. And with this bleeding taking place you need to make sure that the blood pressure is properly stabilized. The nuclear scan may be useful for persistent bleeding of unclear source. Nuclear scan. Colonoscopy may be used in active bleeding. We'll talk about colonoscopy and when you would use it and when you would not. But for the most part you want to make sure that you're able to find the source of this lower GI bleeding. Angiographic embolization of the bleeding source most effective therapy in setting of an active bleed. Well literally by blocking the bleeding, most effective in terms of halting the actual loss. The causes and differentials that you want to keep in mind. Diverticular disease, painless rectal bleeding. Diverticulosis you've heard of, we'll talk about this in greater detail. Angiodysplasia is right up there. Do not forget about what made that then happened within blood vessels in which you might then dysplasia. Inflammatory bowel diseases especially Ulcertaive colitis, more bleeding, but remember Crohn's could also result in lower GI bleeding. Ischemia is a big time important and an emergent matter that we'll talk about and known as your Ischemic Bowel Disease. Cancers, Meckel's Diverticulum and Hemorrhoids may all be important differentials for lower GI bleeding....
