Diagnostic challenge of primary and secondary omental torsions: report of three cases

Omental torsion is a rare condition which usually requires surgical approach. Torsion is caused by the vascular insufficiency due to twisting of omentum along its long axis. This condition is rarely diagnosed preoperatively and may be misinterpreted as other causes of acute surgical abdomen. So, recognition by surgeons is important for differential diagnosis. We report three cases of primary omental torsion, and diagnostic and therapeutic management of patients. The resection of effected omentum segment is the most preferred treatment. However, conservative treatment may be the option for selected cases. Clinicians must be aware of clinical and radiological findings of omental torsion for accurate diagnosis. Laparoscopic approach may be used favorably for both, diagnosis and treatment.
