Gastroschisis

(paraomphalocele, laparoschisis, abdominoschisis, abdominal hernia) A developmental abnormality, which occurs as an abdominal wall defect associated with evisceration of the intestine (2.5 cases/10,000 births). Usually occurs as an isolated defect, defects in other organ systems have been reported in up to 35% of children. There are several theories as to the cause of this abdominal wall defect, including recently failure of the yolk sac and related vitelline structures to be incorporated into the umbilical stalk. Note that the similar appearing abnormality of omphalocele involves a lack of normal return of the bowel to the abdominal cavity and position relative to the umbilical cord.
