5. How do the clinical presentations of omphalocele and gastroschisis differ?

In gastroschisis, the abdominal opening is positioned lateral to the umbilical cord insertion, while in omphalocele, the abdominal contents are herniated through an enlarged umbilical ring and the umbilical cord is inserted in the distal part of the membrane covering the anomaly. However, omphalocele membranes can sometimes rupture prior to or duringm delivery, resulting in an anomaly that may be difficult to distinguish from gastroschisis.
