Acute abdomen caused by greater omentum torsion: A case report and review of the literature.

Torsion of the greater omentum is a rare cause of acute abdomen. Based on etiopathogenesis, it can be classified as primary or secondary. However, regardless of the cause, segmentary or diffuse omental necrosis will follow. Preoperative diagnosis is not easy, though abdominal ultrasound and computed tomography (CT) scans may show peculiar features suggestive of omental torsion. Laparoscopic resection of the affected omentum is the treatment of choice. Presently reported was a case of primary omental torsion, in addition to a comprehensive literature review.
