Umbilical hernia repair in children: is pressure dressing necessary.

The use of pressure dressing to cover the sutured surgical wound is usually considered a routine conclusion to the repair of umbilical hernias in children. The wound is usually left dressed for a minimum of 5-7 days. The main purpose of pressure dressing is prevention of a hematoma formation. The aim of this study was to compare the surgical outcome after umbilical hernia repair in children when the wounds were covered using pressure dressing or left exposed without dressing after the completion of wound closure. Ninety-six patients with umbilical hernia repair were prospectively randomized to receive pressure dressing (n=52) or have their wounds left exposed without any dressing (n=44) after the completion of wound closure. None of the hernias were huge umbilical hernia and none required an umbilicoplasty. In the group who received pressure dressing, one patient developed wound infection 1.9% while no patients developed wound infection in the group who had their wounds exposed without any dressing. In children, there was no significant difference in terms of wound infection, hematoma or seroma formation and recurrence rate after applying pressure dressing or leaving the surgical wounds exposed without any dressing after completion of wound closure. Pressure dressing after umbilical hernia repair may be unnecessary.
