title: Double omental hernia--case report on a very rare cause of intestinal obstruction.
abstract: BACKGROUND
  We report a case of transomental herniation of the ileum through a defect in the gastrocolic ligament with re-emergence through a defect in the gastrohepatic ligament. This type of herniation is extremely rare and a review of the literature is presented.
  
  
  METHODS
  A 41-year-old Chinese male presented with signs and symptoms of intestinal obstruction.
  
  
  METHODS
  An urgent laparotomy was undertaken and he was found to have a rare form of intra-abdominal hernia. The hernia was reduced and the defects were closed.
  
  
  RESULTS
  Postoperative recovery was unremarkable.
  
  
  CONCLUSIONS
  Urgent operation should not be delayed because of the high mortality associated with strangulation.
