Herniation through the foramen of Winslow. Report of two cases.

PURPOSE

Two clinical cases of internal herniation through the foramen of Winslow are presented. The first case concerns herniation of the cecum and ascending colon. In the second patient, the ileum was herniated through the foramen epiploicum.

METHODS

Preoperative assessment of clinical and radiologic findings suggested diagnosis.

RESULTS

Final diagnosis was only made at laparotomy. Reduction of hernia could be performed by pulse traction, and no signs of intestinal necrosis were seen.

CONCLUSION

Herniation through the foramen of Winslow should be taken into account when making a differential diagnosis for upper gastrointestinal tract obstruction.
