As the umbilical hernia is treated, whether necessarily to do or make operation if pains arise seldom.

[Elshanskij I.V.]

The hernia is not operated only in the event that the risk of operation (infarcts, insults and t is high. Item in the anamnesis). In all other cases operation is shown unequivocally.
