Over a period of 5 years, four cases of incarcerated (one strangulated
) umbilical hernia (UK) in children were observed and treated in Saint
-Denis, France. In a review of the literature, only 45 descriptions of
complicated UHs in children were found worldwide. Incarceration of UH
s is considered to be very rare in children, however, it appears to oc
cur more frequently than it is generally believed. Therefore, a more a
ctive therapeutic approach is recommended even in smaller hernias, fro
m more than an aesthetic point of view.
