Umbilical hernia repair

Umbilical hernia is divided into 3 types, namely umbilical bulge (infant or embryonic umbilical hernia), pediatric and adult. Umbilical bulge is the rarest, with a rate of 1/5000. It is a congenital defect. The abdominal organs protruding into the umbilical cord are covered with only a layer of amniotic membrane and peritoneum without skin covering. If exposed to air for a long time, it will quickly dry and necrosis, which will cause the internal organs to bulge from the defect. Pediatric umbilical hernias are more common, with an incidence rate of 1%, mostly occurring within 2 years of age, often due to congenital umbilical abdominal wall defects and increased intra-abdominal pressure. The hernia sac is covered with skin and peritoneum. Adult-type umbilical hernias are rare and occur more than middle age. The cause is on the one hand due to a defect in the umbilicus, and on the other hand due to increased intra-abdominal pressure.
