MIDLINE HERNIAS

MIDLINE HERNIAS

The embryonic umbilical ring encircles a defect in the ventral abdominal wall transmitting structures connecting the fetus to the placenta ( Figure 17.8 ). Umbilical hernias are common following incomplete closure of the umbilical ring, though incarceration is rare. Most umbilical hernias resolve by 4 years. Supraumbilical hernias are defects in the linea alba just above the umbilical ring; these do not close but are still repaired around 4 years. Epigastric hernias are defects higher still that allow a small amount of preperitoneal fat to prolapse; they are repaired if symptomatic. MIDLINE HERNIAS
