Pediatric Umbilical Hernia
Etiology
Umbilical hernia in children results from incomplete closure of the fascia of the umbilical ring, through which intraabdominal contents may protrude.
After separation of the umbilical cord, usually, the ring undergoes spontaneous closure through the growth of the rectus muscles and fusion of the fascial layers.
A failure or delay in this process leads to the formation of an umbilical hernia.
The exact etiology is unknown, but usually, occurs through the umbilical vein component of the ring.
