Herniation of the caecum and ascending colon through the foramen of Winslow: a case report and review

Abstract

Approximately 5% of intestinal obstruction cases are caused by internal herniation. Caecal herniation through the foramen of Winslow is considered a rare event. The management of caecal herniation remains challenging due to the lack of literature highlighting this pathology. A 66-year-old woman was admitted with a 24-hour history of epigastric pain radiating to the back. The pain was associated with nausea and vomiting of gastric contents. On examination, the abdomen was soft with mild tenderness but no signs of peritonism or distension. The abdominal x-ray and a computed tomography were in keeping with caecal volvulus and confirmed that the caecum was not in the right iliac fossa. In a midline laparotomy procedure, the ileum, caecum and ascending colon were noted to be herniating into the foramen of Winslow. A right hemicolectomy with a handsewn anastomosis was performed. The foramen of Winslow was not closed. No postoperative complications occurred. A literature review showed a lack of similar cases with no agreed management consensus. The laparotomy approach is comparable to the laparoscopic approach and no caecal herniation recurrence after open/laparoscopic surgical procedures were identified. Awareness of caecal herniation allows early diagnosis and timely surgical management is needed in prevent patient morbidity and mortality.
