[Herniation of the cecum and ascending colon through Winslow's foramen and the lesser omentum. A case report].

Internal hernia into epiploic foramen is a rare clinical entity, representing 1% of all herniae and 8% of internal herniae. We report a peculiar case of internal herniation presented during a laparotomy for acute colecystitis where the caecum and ascending colon entered the lesser sac through the forame of Winslow and reentered the main abdominal cavity through a congenital defect of the lesser omentum.
