Umbilical hernia is a congenital developmental defect, which is more common in male infants than in female infants. During the fetal period, three umbilical vessels pass through the umbilical ring. After the baby is born, the blood vessels passing through the umbilical ring gradually shrink and the umbilical ring closes. But it often becomes a weak point in the baby’s abdominal wall. If the baby’s bilateral abdominal muscles and their front and rear sheaths are not fully closed after the umbilical cord stump falls off, the intestinal canal will protrude from the unclosed umbilical ring and form umbilical hernia when the pressure in the abdominal cavity increases.  

1. Omphalitis

Interpretation of omphalitis: omphalitis is the inflammation of the umbilical cord caused by the infection of bacteria due to improper treatment or care of the umbilical cord stump at or after the birth of a newborn baby.

Omphalitis: slight local redness and swelling, with a small amount of secretion; In severe cases, it can also be seen that there are redness and swelling around the umbilical cord, purulent secretions flowing out of the umbilical fossa and smelling, and even periumbilical cellulitis or abscess, which can be complicated with peritonitis, sepsis, sepsis, etc.

Appropriate treatment: if the lesion is light, the local part can be wiped with complex iodine, or first with iodine tincture and then 75% alcohol. If you find redness and swelling around the umbilicus, a large number of purulent secretions in the umbilicus fossa and odor, you should take your baby to the hospital for diagnosis and treatment immediately.

2. Umbilical antler

Interpretation of umbilical antler: in addition to umbilical vessels and urachus, there is also a structure called yolk tube in the umbilical cord. The yolk tube is connected with the baby’s small intestine. The umbilical antler is actually the residue of the distal mucosa after the yolk tube is blocked in the fetal period. In addition, once the umbilical cord falls off and causes omphalitis, repeated inflammatory stimulation will also cause local granulation tissue proliferation and form umbilical antler.

Performance of umbilical antler: Pink granulation tissue with the size of soybean and higher than the bottom of umbilical fossa can be seen in the center of navel, with secretion outflow, and occasionally a small amount of bloody secretion can be seen.

Proper treatment: Mommy should not handle the baby’s umbilical antler without authorization, but should ask experienced medical staff to handle it. Silver nitrate is generally used for local cauterization, and large umbilical antler needs surgical treatment. In case of complications, hospitalization is required.
