Omental torsion, a rare cause of acute abdomen in children and adults, is difficult to correctly diagnose before surgery because it mimics the common causes of acute surgical abdomen. We present a case of greater omental torsion that was diagnosed by laparoscopy. A 37-year-old man presented with right lower abdominal pain and was suspected to have appendicitis. ⋯ Laparoscopy revealed omental torsion, and an omentectomy was performed. The patient's pain had significantly reduced post-surgery, and post-operative recovery was uneventful. Thus, laparoscopic examination is useful for accurately diagnosing omental torsion and is less invasive than surgery.
