Presentation
A hernia is present at the site of the umbilicus (commonly called a navel, or belly button) in the newborn; although sometimes quite large, these hernias tend to resolve without any treatment by around the age of 2-3 years. Obstruction and strangulation of the hernia is rare because the underlying defect in the abdominal wall is larger than in an inguinal hernia of the newborn. The size of the base of the herniated tissue is inversely correlated with risk of strangulation (i.e. narrow base is more likely to strangulate).
Babies are prone to this malformation because of the process during fetal development by which the abdominal organs form outside the abdominal cavity, later returning into it through an opening which will become the umbilicus.
