Epiploic appendagitis and omental infarction

Epiploic appendagitis and omental infarction are benign self‐limiting disorders. They are uncommon, though more common than is generally assumed. In both diseases the main clinical symptom is non‐specific focal abdominal pain, with a normal or moderately raised white blood cell count and erythrocyte sedimentation rate. These findings often mimic an abdominal surgical emergency, which leads to clinical misdiagnosis of more common conditions such as appendicitis or diverticulitis. This may result in an unnecessary laparotomy. Ultrasonography (US) and computed tomography (CT) show characteristic features in most patients, allowing a secure non‐operative diagnosis. Patients correctly diagnosed can avoid an operation or costly observation in hospital. Copyright © 2001 Taylor and Francis Ltd.
