title: Herniation of the colon through the foramen of Winslow-A case report.
abstract: BACKGROUND
  Herniation of the bowel through the foramen of Winslow is a rare condition presenting with acute abdominal pain. Diagnostic delay often results in high morbidity and mortality.
  
  
  METHODS
  A patient presented with right sided acute abdominal pain. Computed tomography showed herniation of the ascending colon through the foramen of Winslow which could be reversed laparoscopically without the need for bowel resection. There were no postoperative complications and no recurrences have occurred to date.
  
  
  CONCLUSIONS
  Bowel herniation through the foramen of Winslow is very rare, comprising only 8% of all internal herniations. Historically, the majority of cases was diagnosed intra-operatively and bowel resection was necessary because of ischemia. With the introduction of computed tomography, the diagnosis can be made earlier, possibly resulting in a lower morbidity and mortality rate.
  
  
  CONCLUSIONS
  Herniation through the foramen of Winslow is a rare condition. Patients will present with sudden onset abdominal pain. Early imaging helps to recognize the diagnosis and could prevent bowel ischemia.
