Ischemic colitis (IC) is the most common form of intestinal ischemia and results from inadequate colonic perfusion from low flow states, arterial thrombosis, embolism, or ligation and can also occur postoperatively from cardiac or gastrointestinal surgery. Most IC is idiopathic or caused by shock associated with sepsis. Treatment is generally supportive and most patients recover with conservative measures; however, approximately 20% will require surgical intervention, which carries a high in-hospital mortality. A small percentage of patients also have chronic forms of IC that may lead to stricturing and chronic colitis.
