Handlebar injuries in children are commonly associated with significant gastrointestinal and solid organ damage. In this paper, we report a rare case of an isolated omental injury in a 6-year-old child after a blunt trauma with a bicycle handlebar. We describe a successful laparoscopic omentectomy performed with the LigaSure Atlas. This is the first report to describe the advantages of laparoscopy and the use of electrothermal bipolar vessel sealers, such as the LigaSure Atlas device, for the control and treatment of bleeding owing to traumatic omental infarction.
