Herniation of the hepatic flexure through the foramen of Winslow: a case report.

Herniation through the foramen of Winslow is among the rarest of internal hernias. Predisposing factors include an enlarged epiploic foramen, a mobile cecum and ascending colon, and an abnormal length of small bowel mesentery. Obstruction, strangulation, and perforation with associated metabolic and septic sequelae are the major complications associated with this disease. We report a case of herniation through the foramen of Winslow in which the diagnosis was established preoperatively.
