Most umbilical hernias will close by 4 to 5 years of age without treatment.
Complications including incarceration, strangulation, and rupture are uncommon in children.
Elective outpatient repair is associated with a low recurrence rate.
Infection and bleeding are the two most common postoperative complications.
Compression therapy (such as abdominal binders) is not helpful and may be harmful.
An umbilical hernia is a defect of the anterior abdominal wall fascia that occurs when the umbilical ring fails to close. The defect allows protrusion of a peritoneal sac that is covered by skin and may contain intra-abdominal contents, such as omentum or bowel.
