Adult cases of isolated traumatic duodenal rupture caused by bicycle handlebar injury are extremely rare. We report a patient who experienced persistent abdominal pain after having a bicycle handlebar injury. Since the injury is hard to identify, abdominal computed tomography is performed to confirm the diagnosis. We also present a management flow chart to help physicians managing handlebar injuries in adults. ? 2015, Medcom Limited.
