Hernia through the foramen of Winslow.

The authors present a patient who has ascarid-containing jejunum herniated through the foramen of Winslow and incarcerated. Some remarkable anatomic abnormalities were noticed upon operation. These consisted of a short ascending colon, an unusually large foramen of Winslow, and smallness of the greater omentum. Before reduction, resection of the herniated and incarcerated segment of jejunum were performed. Barium enema and swallow are valuable diagnostic acids, as well as the plain film of the abdomen, but we prefer gastrographin study. With it the dangers of perforation and peritonitis are avoided.
