Omental infarction, or omental torsion, is an acute vascular disorder which compromises tissue of the greater omentum—the largest peritoneal fold in the abdomen. Signs and symptoms
Patients will present with a sudden onset of cramps/abdominal pain or a stitch. The pain localises in the area of the umbilicus and can radiate to the lumbar and surrounding regions. Causes
Omental infarction is a rare cause of acute abdomen pain with reported incidence being less than 4 per 1000 cases of appendicitis. Omental infarction usually presents as right-sided abdominal pain although seldom causing left-sided abdominal pain and even epigastric pain. The dominion of right-sided abdominal pain in omental infarction has been attributed to right segmental infarction as a result of the tenuous blood vessels in this part of the omentum as well as its longer size and higher mobility in comparison to the left side which subjects it to torsion. Obesity is a known risk factor for omental infarction. The theory behind this is that fat accumulation within the omentum occludes blood supply to the distal parts of the omentum in addition to making it more susceptible to torsion. Other risk factors for omental infarction are polycythemia, hypercoagulability, and vasculitides plus other conditions which predispose to torsion such as trauma, sudden body movements, coughing, heavy food intake, and hyperperistalsis.Historically, omental infarction was diagnosed only intraoperatively during surgery for presumed appendicitis or other causes of acute abdomen.
