Ischemic colitis in five points: an update 2013.

BACKGROUND: Ischemic colitis is the most common form of intestinal ischemia. The presence of diarrhea and mild lower gastrointestinal bleeding should guide the diagnosis. Although many laboratory tests and radiographic images may suggest the diagnosis, colonic endoscopic with histological analysis of biopsies is the gold standard for identification of colonic ischemia. aim : The aim of this study was to resume in 5 points: the epidemiology, the clinical features, the diagnostic approach and the management of ischemic colitis in five points. methods: Review of literature. results: Incidence of ischemic colitis was between 3 and 10%. The clinical presentation is predominated by the non gangrenous form associating abdominal pain, tenderness, diarrhea and lower gastrointestinal bleeding. The most frequent causes are represented by systemic hypoperfusion. Laboratory tests can orientate the diagnosis but are unspecific. Radiographic images based on computed tomography or more recently magnetic resonance imaging may suggest the diagnosis, but the confirmation will be given by endoscopic visualization of colonic mucosa with histological analysis of biopsies. Conservative treatment is the most often sufficient to improve colonic lesions. Surgical treatment is reserved for perforations and strictures.

CONCLUSION: The incidence of colonic ischemia is difficult to ascertain. The diagnosis is usually made by medical history, examination, and endoscopy which have become the diagnostic procedure of choice. A high index of suspicion and prompt management are essential for optimum outcomes in patients with colonic ischemia.
