Introduction: The foramen of Winslow, otherwise known as the epiploic or omental foramen, is a normal orifice 
that allows virtual communication between the greater and lesser peritoneal cavities. Hernias through the foramen 
of Winslow are extremely rare. 
Method: We present a case of a patient with strangulated ileum herniated through the foramen of Winslow. 
Case summary: A 36-year-old man presented to the hospital with complaint of acute epigastric pain since 1 day 
and 6-7 episodes of vomiting. An emergency computed tomography scan revealed a loop of ileum in the lesser 
sac. Emergency laparotomy was performed, a herniated loop of ileum that had become strangulated at its entry to 
the lesser sac via the foramen of Winslow was observed. The loop of ileum was reduced but was nonviable, which 
had to be resected with a primary anastomosis. The patient’s postoperative recovery was uneventful. 
Results: Hernias through the foramen of Winslow are extremely rare. Delayed diagnosis is often observed, 
resulting in bowel strangulation and high mortality. 
Conclusion: Herniation through the foramen of Winslow is a difficult diagnosis and must not be missed. Early 
cross-sectional imaging and surgical intervention are advised in order to reduce morbidity.
