Foramen of Winslow hernia

Abstract

Foramen of Winslow hernia is a rare surgical condition that is notoriously difficult to diagnose and most patients are diagnosed only at the time of surgery. As such, a high index of suspicion is necessary to avoid potentially life‐threatening complications. The present paper describes two such cases. In the first case, a freely suspending gall bladder herniated into the lesser sac via the foramen of Winslow. This was diagnosed during a scheduled laparoscopic cholecystectomy. In the second case, the caecum herniated into the foramen of Winslow causing small bowel obstruction and ischaemic hepatitis. Diagnostic dilemma and treatment of the condition is also described.
