title: Increased risk of complications in acute onset intestinal malrotation.
abstract: BACKGROUND
  Intestinal malrotation is a potentially life-threatening illness which presents in many different ways and the symptoms span from acute to chronic. The purpose of this study was to determine the clinical presentation of intestinal malrotation at all ages.
  
  
  METHODS
  This was a retrospective study of all patients operated for intestinal malrotation at Odense University Hospital in the period from 1/1/1990 to 1/4/2012. The following information was recorded in the hospital records: demographics, presentation, duration of symptoms, diagnostic imaging and outcome. Patients were classified into two age groups: children (0-15 years) and adults (over 15 years).
  
  
  RESULTS
  A total of 54 patients were identified - 47 children and seven adults. Children frequently presented with acute symptoms, while adults mostly had chronic symptoms. The mortality rate was 6% and 14% for children and adults, respectively (p = 0.44). Deaths were due to volvulus.
  
  
  CONCLUSIONS
  Intestinal malrotation may have an acute and a chronic form in both children and adults. Complications and death only occurred in patients with an acute onset. Proper knowledge about symptoms is important for a good outcome.
