Colonic ischaemia, commonly referred to as ischaemic colitis, is the most common type of intestinal ischaemia. The term "ischaemic colitis" was used by Marston (1966) with three typical patterns of injury described: transient reversible ischaemia, ischaemic ulcers with stricturing, and gangrenous ischaemic colitis. Dominant presenting symptoms were colicky abdominal pain, vomiting, bloody diarrhea, and hematochezia. Patients often have minimal signs on clinical examination. Most patients were diagnosed at colonoscopy. Two regions that are believed to be anatomically vulnerable to ischemic disease are "Griffith’s point", at the splenic flexure and "Sudeck’s critical point", of the Drummond marginal artery. Clinically, ischaemic colitis is classified as non-gangrenous or gangrenous. Non-gangrenous ischaemic colitis involves the mucosa and submucosa and accounts for 80-85 percent of all cases of ischaemic colitis. Non-gangrenous ischaemic colitis is further subclassified into transient, reversible ischaemic colitis with a less severe form of injury and chronic, non-reversible ischaemic colitis, which includes chronic colitis and stricture and has a more severe form of injury. Gangrenous ischaemic colitis accounts for the remaining 15-20 percent of cases and manifests as the most severe form of injury. It includes acute fulminant ischaemia with transmural infarction that may progress to necrosis and death. Specific indications for operation include peritonitis, perforation, recurrent fever or sepsis, clinical deterioration in patients refractory to medical management. Relative indications include fulminant colitis, massive hemorrhage, chronic protein losing colopathy, and symptomatic ischemic structure.
