Spontaneous reduction of acute cecal herniation through the foramen of Winslow

This is the case of a 70-year-old woman who presented to the emergency department complaining of 2 hours of acute-onset epigastric pain. She had experienced this pain once before which had spontaneously resolved. Axial imaging demonstrated the cecum in an abnormal position within the lesser sac, as well as compression of the inferior vena cava and portal vein. She was taken emergently to the operating room for laparotomy, where a free-floating cecum and ascending colon was identified without ischemia, and a right hemicolectomy was performed. Foramen of Winslow hernias are rare internal hernias with a high rate of strangulation and bowel ischemia, requiring urgent surgical intervention. Operative treatment depends on the type of herniated viscera. Spontaneous reduction is not well documented.
