Omental torsion is a rare cause of acute abdomen. The clinical symptoms can mimic other acute abdominal disorders, and therefore many patients are often diagnosed during a laparotomy performed under a presumptive diagnosis of appendicitis, cholecystitis and so on. Recent advances in diagnostic modalities has made it possible to determine the correct preoperative diagnosis of omental torsion, and the chances of treating this rare condition are therefore expected to increase. Laparoscopic surgery has been used extensively for various emergent disorders; however, the laparoscopic management of omental torsion might be troublesome for most surgeons. A case of omental torsion secondary to inguinal hernia is herein reported, where a huge torted omentum was successfully managed laparoscopically. It was useful to hang up the pedicle of the congested and fragile omentum with polyester tape to manage it atraumatically. Moreover this device made it easy to remove of the specimen through a 4-cm minilaparotomy.
