title: Primary omental torsion: report of two cases.
abstract: Two patients with omental torsion, who presented with acute abdomen, are reported. The first case, a 14-yearold boy, was admitted for acute appendicitis. During surgery, omental torsion on the long axis was diagnosed and the involved omentum was resected. The patient had not experienced any previous abdominal surgery. The second case, a 49-year-old man, was admitted with symptoms of acute abdomen. Similarly, a laparotomy revealed omental torsion around the long axis. This patient also had no history of previous abdominal surgery. The involved portion of the omentum was also resected. Omental torsion is a rare cause of acute abdomen in children and adults, who may present with various signs and symptoms mimicking other etiologies of acute abdomen. A preoperative diagnosis may therefore be difficult and it usually can only be established during surgery.
