Omphalocele is a birth defect of the abdominal wall in which the intestines, liver or other organs stick out through the belly button.[1] The organs are covered in a thin and nearly clear sac.[1] Complications may include infection, insufficient blood flow, and small lungs.[1]
The cause is generally unclear.[1] Risk factors include alcohol, smoking, obesity, and certain medications.[1] It may be associated with other syndromes including Beckwith-Wiedemann syndrome, trisomy 13, trisomy 18, trisomy 21, or pentalogy of Cantrell.[2] The underlying mechanism involves failure of the intestines to return to the abdomen by the 11th week of pregnancy.[1] Diagnosis may occur before birth via blood tests or an ultrasound or after birth.[1]
Management depends on the size of the omphalocele.[1] If small, surgery may be done soon after birth.[1] If large, the organs may be covered with a special material and slowly pushed back in over time.[1] Mechanical ventilation may be required to support poorly developed lungs.[2] Long term survival is about 80% with the outcome mostly determined by associated abnormalities.[2]
Omphalocele occurs in about 1 in 4,200 births.[1] Males are affected more often than females.[2] The condition was first described in the 16th century by Ambrose Pare.[3] The condition was clearly differentiated from gastroschisis in 1953.[3]
