Diverticular Bleeding

• Diverticular bleeding is the  most common source of lower GI bleeds and accounts for 17 to 40 percent of cases
• The most common presentation (80%) is massive painless rectal bleeding. 
• Patients may have some cramping prior to a bloody bowel movement but otherwise will typically have no abdominal pain.
• The majority of the cases will resolve spontaneously, but those requiring more than 4 units of Packed Red Blood Cells should be considered for an angiogram or  surgery.
• Angiography can be used to localize the site of bleeding and embolize the bleeding source. 
• If embolization fails the patient may require a partial colectomy to treat the bleeding source.
