Abstract
A 24-year-old man visited our hospital complaining of abdominal pain and nausea. Abdominal X-ray films showed distended small-bowel gas at the height of L1 vertebrae. Enhanced abdominal CT scan visualized the dilated intestine in the space between the portal vein and inferior vena cava from the Winslow foramen. Sagittal and coronal sections of abdominal CT scan also visualized small intestine in the omental bursa between the portal vein and inferior vena cava. With the diagnosis of Winslow foramen hernia, and emergency operation was performed. Upon laparotomy, the ileum had become in carcerated about 30 cm into the omental bursa. Manual reduction was performed without intestinal resection since the herniated bowel was viable. In this case, we made an early diagnosis preoperatively and effective treatment using MD-CT.
