Abstract

True congenital umbilical hernia, described by other authors under the names exomphalos, omphalocele or hernia funiculi umbilicalis, is a relatively rare condition. It has been described as occurring about once in every 5,000 to 6,000 births, and it is apparently more common in the male than in the female.
