The herniated visceral are included in a sac which is .formed internally by the peritoneum and externally by Whaon's jelly and the amnion. Omphalocele is associated with number of congenital anomalies Anomalies Gastroschisis Gastroschisis is a herniation of the abdominal viscera through a paraumibilical defect of the anterior abdominal wall. The defect is usually located at the right side of the cord inseion and comprises full thickness of the abdominal wall. The herniated organ is usually bowel and very rarely other structures are involved. In contrast to omphalocele - "Gastrochisis is rarely associated with other congenital anomalies". The most frequent associated anomalies are gastrointestinal in origin and are related to the same vascular embryologic problem that originates the gastrochisis. - Intestinal atresia or stenosis (7-30%) cardiac malformation seen in 8% cases. It is also associated with I.U.G.R.
