Three Nigerian infants with spontaneous rupture of an umbilical hernia
are described. In two, hernias developed in the neonatal period follo
wing umbilical sepsis. Rupture occurred at the ages of 2 and 3 months,
respectively, and was probably precipitated by raised intra-abdominal
pressure resulting from excessive crying. The third child had a large
, ulcerated umbilical hernia which ruptured at 10 months and was preci
pitated by damage to the overlying skin. The children were treated suc
cessfully.
