title: Pictorial Interlude: caught up in a 'whirl'.
abstract: A patient with the 'whirl sign' on computed tomography (CT) is 25.3 times as likely as a patient without to have small-bowel obstruction (SBO) necessitating surgery. There is therefore an important role for the 'whirl sign' in assessment of patients with clinical and radiological signs of SBO.
