==Overview== | |||
Umbilical hernia is a [[congenital malformation]], especially common in [[Infant|infants]] of African descent. However, it can be an [[Acquired disorder|acquired]] condition as well. In 1855, Dr. Henry Porter was the first to publish a case of umbilical hernia with rupture. In 1876, Dr. MG Oxley published a case of umbilical hernia operation. The [[pathophysiology]] of umbilical hernia involves the weakness of [[Abdomen|abdominal]] [[fascia]] or failure to fully form the [[fascia]] which may lead to an umbilical hernia in the [[Infant|newborn]]. During the fifth to tenth weeks of [[gestation]], the intestinal tract undergoes rapid growth with protrusion of the [[Abdomen|abdominal]] content outside the [[Abdomen|abdominal]] cavity. This is followed by a gradual re-entry of the [[Abdomen|abdominal]] cavity and then the narrowing of the [[umbilical]] ring which completes the process of [[abdominal wall]] formation. Umbilical hernia may be caused by [[Congenital disorder|congenital]] [[Congenital disorder|malformation]] of the [[navel]] or it can be [[Acquired disorder|acquired]] due to increased intra-[[Abdomen|abdominal]] pressure caused by [[obesity]], [[Physical exercise|lifting]], [[Cough|coughing]], or multiple [[Pregnancy|pregnancies]]. It should be differentiated from [[epigastric hernia]], [[Spigelian hernia]], and [[incisional hernia]]. The [[prevalence]] of umbilical hernia is approximately 0.015 to 0.023 per 100,000 of newborns affected in USA. It affects [[Male|males]] and [[Female|females]] equally. Common risk factors in the development of umbilical hernia includes [[Infant|infants]], [[pregnancy]], African American, [[Glycosaminoglycan|mucopolysaccharide]] storage diseases, [[Beckwith-Wiedemann syndrome]], and [[down syndrome]]. Umbilical hernias are usually [[asymptomatic]] and resolve on their own. Common [[Complication (medicine)|complications]] of umbilical hernia include incarceration, [[Strangling|strangulation]], [[Skin changes|skin]] color changes, and [[ascites]]. Umbilical hernia presents with a soft swelling over the belly button that often bulges when the [[Infant|baby]] sits up, cries, or strains. The bulge may be flat when the infant lies on the back and is quiet. Treatment is by the size of the defect, the age of the [[patient]], and the cosmetic appearance of the [[abdomen]]. Most defects close spontaneously by the age of two years. Physical examination of patients with umbilical hernia is usually remarkable for a protruding [[umbilical]] mass examined in the standing and [[supine]] positions to determine the size of a [[hernia]] +/- [[valsalva maneuver]]. There are no [[ultrasound]] findings associated with umbilical hernia. However, an [[ultrasound]] may be helpful in the diagnosis of complications of umbilical hernia, which include incarceration, [[Strangling|strangulation]], and size of the [[hernia]]. Umbilical hernia surgery is indicated when umbilical hernia is larger than 2cm, “elephant’s trunk” appearance, does not spontaneously close by 5 to 6 years of age, symptomatic, [[Strangling|strangulation]], or increases in size after the age of 1 to 2 years. Surgical repair for an uncomplicated umbilical hernia is done under general [[anesthesia]] as an outpatient procedure. [[Mesh]] implantation include bridging the defect and placing a preperitoneal [[mesh]] with [[suture]] repair. Recurrence is seen in patients with elevated intra-[[Abdomen|abdominal]] pressures. [[Laparoscopic surgery|Laparoscopic]] technique is reserved for large defects or recurrent umbilical hernias. | |||

Overview
Umbilical hernia is a congenital malformation, especially common in infants of African descent. However, it can be an acquired condition as well. In 1855, Dr. Henry Porter was the first to publish a case of umbilical hernia with rupture. In 1876, Dr. MG Oxley published a case of umbilical hernia operation. The pathophysiology of umbilical hernia involves the weakness of abdominal fascia or failure to fully form the fascia which may lead to an umbilical hernia in the newborn. During the fifth to tenth weeks of gestation, the intestinal tract undergoes rapid growth with protrusion of the abdominal content outside the abdominal cavity. This is followed by a gradual re-entry of the abdominal cavity and then the narrowing of the umbilical ring which completes the process of abdominal wall formation. Umbilical hernia may be caused by congenital malformation of the navel or it can be acquired due to increased intra-abdominal pressure caused by obesity, lifting, coughing, or multiple pregnancies. It should be differentiated from epigastric hernia, Spigelian hernia, and incisional hernia. The prevalence of umbilical hernia is approximately 0.015 to 0.023 per 100,000 of newborns affected in USA. It affects males and females equally. Common risk factors in the development of umbilical hernia includes infants, pregnancy, African American, mucopolysaccharide storage diseases, Beckwith-Wiedemann syndrome, and down syndrome. Umbilical hernias are usually asymptomatic and resolve on their own. Common complications of umbilical hernia include incarceration, strangulation, skin color changes, and ascites. Umbilical hernia presents with a soft swelling over the belly button that often bulges when the baby sits up, cries, or strains. The bulge may be flat when the infant lies on the back and is quiet. Treatment is by the size of the defect, the age of the patient, and the cosmetic appearance of the abdomen. Most defects close spontaneously by the age of two years. Physical examination of patients with umbilical hernia is usually remarkable for a protruding umbilical mass examined in the standing and supine positions to determine the size of a hernia +/- valsalva maneuver. There are no ultrasound findings associated with umbilical hernia. However, an ultrasound may be helpful in the diagnosis of complications of umbilical hernia, which include incarceration, strangulation, and size of the hernia. Umbilical hernia surgery is indicated when umbilical hernia is larger than 2cm, “elephant’s trunk” appearance, does not spontaneously close by 5 to 6 years of age, symptomatic, strangulation, or increases in size after the age of 1 to 2 years. Surgical repair for an uncomplicated umbilical hernia is done under general anesthesia as an outpatient procedure. Mesh implantation include bridging the defect and placing a preperitoneal mesh with suture repair. Recurrence is seen in patients with elevated intra-abdominal pressures. Laparoscopic technique is reserved for large defects or recurrent umbilical hernias.

Umbilical hernia surgery is indicated when umbilical hernia is larger than 2cm, “elephant’s trunk” appearance, does not spontaneously close by 5 to 6 years of age, symptomatic, strangulation, or increases in size after the age of 1 to 2 years. Surgical repair for an uncomplicated umbilical hernia is done under general anesthesia as an outpatient procedure.
