How Should Umbilical Hernia in Children Be Treated?

The vast majority of umbilical hernias in infants resolve spontaneously. As the child grows, the abdominal muscles strengthen, and the hernial ring typically narrows progressively until it closes completely. Spontaneous resolution usually occurs between 1 and 2 years of age, though it may still happen as late as 3–4 years; continued observation is therefore appropriate.The size of the umbilical ring is strongly correlated with the likelihood of spontaneous closure: rings approximately 1 cm in diameter generally close without intervention, whereas those exceeding 2 cm—especially if progressively enlarging—have a very low probability of spontaneous resolution.Standard management of umbilical hernia involves conservative observation for children under 2 years old. For children aged 2 years and older, small umbilical hernias may be observed conservatively for an additional 3–6 months; surgical repair is considered if the hernia fails to close during this period.
