Caecum herniation through the Foramen of Winslow

Abstract

Foramen of Winslow herniation is a rare occurrence with a high mortality; it presents a diagnostic challenge with subtle clinical and radiological features. We present a case of caecal herniation through the foramen of Winslow creating a closed loop obstruction which remained undiagnosed until laparotomy. Reduction was achieved with gentle traction after first decompressing the caecum whilst still within the lesser sac.
