Major Disorders: Omphalocele, Gastroschisis
　
Diagnosis

Gastroschisis: Evisceration excluding the liver without a covering membrane, Insertion of the umbilical cord onto the abdominal wallI

Giant Omphalocele: Evisceration including the liver with an intact covering membrane, Insertion of the umbilical cord into the covering membrane

Ruptured giant omphalocele: Evisceration including liver with ruptured covering membrane, Insertion of the umbilical cord into the covering membrane

Ruptured giant omphalocele: Evisceration including liver without a covering membrane, Insertion of the umbilical cord onto the abdominal wall or liver

Prognostic factors in fetal omphalocele: Ruptured or absent covering membrane with evisceration including the liver, Deformity of the spine, Intrauterine growth returdation, Associated anomalies (severe cardiac anomalies, severe chromosomal anomalies)

Fetuses with giant omphalocele requires the protection of the preturm labor, cesarian section and respiratory management immediately after birth.

Giant omphalocele is sometimes complicated with pulmonary hypoplasia which may have no indication for the treatment. Therefore, fetal diagnosis should be made earlier than 20 gestational weeks.

The outcome of gastroschisis is generaly excellent. However, rare cases develop fetal death and respiratory failure after birth.
