tissue from the abdominal wall creates a hole in the right side of the abdominal wall through which the abdominal contents can herniate. In this situation the bowel is exposed to the amniotic fluid throughout much of pregnancy. This exposure results in thickening and shortening of the bowel. Following delivery and surgical repair of the gastroschisis, the bowel often does not function properly for weeks to months. Putting the intestines back in the abdominal cavity increases the pressure in the abdomen and also within the chest. Following surgery, this increased pressure in the abdomen can also interfere with lung function. Occasionally, it is necessary to put a chimney on the abdomen, which encloses the bowel. The intestines are then gradually placed back into the abdomen by squeezing on the chimney until the abdomen has stretched enough to allow the complete replacement of the intestines into the abdomen.
