Complicated umbilical hernias in children.

Umbilical hernia is a common problem in children, particularly in Africans, but complications in these hernias are thought to be rare. In a retrospective study of 47 children presenting for umbilical hernia repair in 14 years, 30 had complications. The complications included acute incarceration 15, recurrent incarceration 10 and spontaneous evisceration 5. Of the 15 with acute incarceration, 2 required bowel resection for gangrene, and an abscess formed in the hernia sac in one. The age of patients with acute incarceration was 2 months-8 years (median 5 years). The 10 with recurrent incarceration were aged 1-3 years (median 3 years). Of the 5 with spontaneous evisceration, one had umbilical sepsis and another intestinal obstruction from intussusception. These patients were aged 3-12 weeks (median 7 weeks). All the complications occurred in hernias that were 1.5 cm or more in diameter. The hernias were repaired using standard methods. Postoperatively, 2 patients developed wound infection. There was no mortality. Though complications of umbilical hernias appear to be rare, there is a need for more active observation of these hernias to identify complications early and treat promptly to avoid morbidity.
