Umbilical hernia is a congenital malformation of the umbilicus. Among adults, it is three times more common in women than in men. An acquired umbilical hernia directly results from increased intra-abdominal pressure caused by obesity, heavy lifting, a long history of coughing, or multiple pregnancies A hernia is present at the site of the umbilicus (commonly called a navel, or belly button) in the newborn; although sometimes quite large, these hernias tend to resolve without any treatment by around the age of 2-3 years. Obstruction and strangulation of the hernia is rare because the underlying defect in the abdominal wall is larger than in an inguinal hernia of the newborn. When the orifice is small (< 1 or 2 cm), 90% close within 3 years (some sources state 85% of all umbilical hernias, regardless of size), and if these hernias are asymptomatic, reducible, and don't enlarge, no surgery is need. In adults symptomatic umbilical herniae almost always require surgical repair. An umbilical hernia can be fixed in two different ways. The surgeon can opt to stitch the walls of the abdomen and place a mesh over the opening and stitch it to the abdominal walls. This is of a stronger hold and is commonly used for larger defects in the abdominal wall. The latest method is of performing this repair laparoscopically through a key-hole and discharge the patient the same evening.
