Umbilical hernia is one of theClosing effect of the myofascial structures in the peritoneum of the umbilical ring allowing protrusion of intra-abdominal organs.

Hear the explanation, in this episode of the podcast white bookwith dr. Vanessa Nascimento, medical editor of the white paper, on Therapeutic methods for umbilical hernia in childhood.

Pathophysiology

The umbilical ring allows the passage of the umbilical vessels during pregnancy. After birth, the opening is closed automatically by the growth of the rectus abdominis muscles and the formation of fibrous tissue at the site of the navel.

In some children, this process fails, resulting in persistent umbilical hernias. Other conditions may be acquired due to increased intra-abdominal pressure, as in patients with ascites or obesity.

 Causative factors

• increased intra-abdominal pressure (ascites, tumors);
