Tip 204: omphalocele/exomphalos

Omphalocele (or exomphalos) is the herniation of the abdominal contents, covered by amnion and attached to the umbilical ring. It ranges from a small hernia into the base of the umbilical cord to a giant exomphalos involving a large portion of the baby’s anterior abdominal wall and containing visera, which carries a high risk of mortality.

About 25% have a chromosomal basis.
