Role of laparoscopy as diagnostic and therapeutic tool in management of omental torsion

We are presenting two cases of omental torsion. Although it is a clinically rare diagnosis but when present it poses a clinical dilemma by mimicking many other common surgical illnesses presenting as acute abdomen especially acute appendicitis. Preoperative diagnosis is also very difficult because both ultrasonography and CT scan are not very specific for making an accurate diagnosis of omental torsion. Case 1 is a rarer type of primary omental torsion which presented with symptoms of acute appendicitis albeit of less severity but ultrasound study was suggestive of appendicular mass. Intraoperatively it was found to be omental torsion with a rather normal looking appendix. Case 2 is a more common type of secondary torsion where omentum got adhered to the site of previous open appendectomy done 30 years ago and got torted. Preoperative CT scan was suggestive of omental mass with decreased vascularity.
