Ischemic colitis refers to a state of colonic injury secondary to inadequate blood flow. Colonic ischemia is the most common form of intestinal ischemia as the colon has fewer vascular collaterals as compared to the remainder of the gastrointestinal tract and can be more prone to episodes of diminished blood flow. Ischemic colitis occurs more frequently in the elderly, and risk factors include diabetes, vasculitis, congestive heart failure, hypercoagulable states, aortoiliac surgery, cancer, and certain drugs. The diagnosis and treatment of ischemic colitis can be challenging as it often occurs in patients who are debilitated and have multiple medical problems. The following chapter will provide a brief synopsis of the management of a patient who presents with suspicion for acute ischemic colitis.
