Gastroschisis is a rare birth defect in which a baby’s intestines or, less commonly, other abdominal organs develop outside the body through an opening in the abdominal wall. It occurs early in pregnancy, although its exact cause is unclear. Prenatal ultrasound and blood tests may detect the condition, allowing doctors to closely monitor the pregnancy[1]. Treatment usually involves surgery soon after birth to return the organs to the abdomen and close the opening. Severe cases may require staged repair. Babies typically need neonatal intensive care, nutritional support and careful monitoring for infection. Long-term complications can include feeding difficulties, nutritional deficiencies, reflux, poor growth and abdominal wall hernias.
Gastroschisis is a rare birth defect in which a baby is born with internal organs, most commonly the intestines, outside their body due to an opening in the abdominal wall. This condition happens early in pregnancy, when the baby’s abdominal wall does not form correctly, leaving an opening through which the internal organs can come out. The exposed intestines are in direct contact with the amniotic fluid, which can cause swelling, irritation and inflammation of the bowel.
The defect is often found during ultrasound scans before the baby is born. Soon after birth, the baby will need specialised medical care and, usually, surgery to place the intestines back inside the abdomen and repair the defect.
Gastroschisis occurs when the abdominal wall does not form correctly while the baby is still in the mother’s uterus. The exact cause of this is unclear, although researchers believe that a combination of genetic and environmental factors may play a role.
Some factors during pregnancy, including maternal smoking and certain other exposures, have been associated with an increased risk of gastroschisis. However, these associations do not mean that they directly cause the condition. Infections and other maternal health factors have also been investigated, but there is currently no single known cause of gastroschisis.
Gastroschisis is usually diagnosed during pregnancy, often through a routine prenatal ultrasound. A blood test showing high levels of alpha-fetoprotein (AFP) may also be a clue and can lead to further testing. The gynaecologist will monitor the foetus’s development and will be able to identify the abdominal wall defect on ultrasound scans.
If the diagnosis is made during pregnancy, gynaecologists will closely monitor the pregnancy and the baby’s growth and development. They will also check for other abnormalities and distinguish gastroschisis from omphalocele, which is a similar birth defect in which the baby’s abdominal organs protrude through an opening in the abdominal wall but are covered by a membrane sac.
Gastroschisis is usually treated after birth. The timing and type of surgery depend on the baby’s condition, the size of the abdominal opening, the condition of the intestines and how swollen the bowel is.
Gastroschisis alone does not usually require a planned C-section, and vaginal delivery may be possible unless there are other obstetric reasons for a caesarean birth.
As soon as the baby is born, special measures are taken to protect the exposed intestines, prevent loss of body heat and fluids, and reduce the risk of infection. The baby is usually stabilised before surgical repair.
The surgeon may perform the repair in one session if the abdominal cavity can safely accommodate the intestines and the bowel is not excessively swollen. In severe cases, when there is significant swelling or there is not enough space in the abdomen, the repair may be done in stages. In such instances, the internal organs may be placed in an external protective bag called a silo. The silo allows the intestines to be gradually returned to the abdomen over several days before the abdominal opening is closed.
Babies with gastroschisis need continuous care after surgery, so they will usually be placed in the neonatal intensive care unit (NICU). The exposed intestines can become swollen and inflamed after prolonged contact with the amniotic fluid, and the bowel may take time to recover and function normally.
These babies may initially have difficulty digesting and absorbing food and may require nutrition through an intravenous line, known as parenteral nutrition[3], until their intestines are ready to tolerate feeds. Babies are also closely monitored for infection and other complications, and antibiotics may be given when clinically indicated.
Babies with gastroschisis may have feeding difficulties, gastroesophageal reflux, nutritional problems and slow growth, particularly if the bowel has been significantly affected. Some babies may also develop abdominal wall or incisional hernias.
In more complicated cases, the intestines may be damaged or may not develop normally. Some babies may have intestinal blockage or intestinal atresia, where a portion of the intestine is not properly formed or is closed. Additional surgery may be required to address these problems.
Most babies with gastroschisis eventually develop normal intestinal function, although recovery can take time, particularly in babies with complicated gastroschisis.
With access to appropriate neonatal and surgical care, the survival rate for babies with gastroschisis is now over 90% in many high-resource settings. Medical developments have made it possible to repair the abdominal wall defect and, in most cases, restore normal intestinal function. Outcomes can vary depending on whether the baby has simple or complicated gastroschisis and whether there is significant intestinal damage.
In early childhood, some children may have difficulty feeding and may resist eating because of discomfort or previous feeding difficulties. As a result, they may develop nutritional deficiencies or have slower growth compared with their peers. However, many children eventually achieve normal growth and are able to eat normally.
Some children and adults who have had gastroschisis may experience ongoing gastrointestinal symptoms, such as abdominal pain, constipation, diarrhoea or altered bowel habits. Abdominal scarring may also affect body image in some individuals, although most children are able to participate in normal physical activities as they grow.
According to paediatric surgeons, long-term gastrointestinal complications can occur in gastroschisis survivors, particularly those who had complicated gastroschisis. Adhesive bowel obstruction is one of the recognised long-term complications and may occasionally require further treatment or surgery.
Most gastroschisis survivors achieve good long-term outcomes and are able to have a good quality of life that allows them to function independently.

Gastroschisis is a rare birth defect in which the baby’s intestines, and sometimes other abdominal organs, develop outside the body through an opening in the abdominal wall.
The exact cause of gastroschisis is unclear. It occurs when the abdominal wall does not form correctly early in pregnancy, with genetic and environmental factors thought to potentially play a role.
Gastroschisis is usually detected during a prenatal ultrasound. A high alpha-fetoprotein (AFP) level in a blood test may also provide a clue and lead to further evaluation.
Gastroschisis does not usually require a planned C-section by itself. Vaginal delivery may be possible unless there are other obstetric reasons for a caesarean birth.
Treatment usually involves surgery to return the exposed intestines to the abdomen and close the abdominal wall opening. The repair may be completed in one procedure or gradually using a protective silo when the bowel is very swollen or the abdomen has limited space.
After surgery, babies need close monitoring because their intestines may be swollen and slow to function. They may require intravenous nutrition, infection monitoring and other specialised neonatal care until they can tolerate feeds.
Yes. Some babies may initially have difficulty digesting and absorbing food and may later experience feeding difficulties, nutritional problems, reflux or slower growth, particularly when the bowel has been significantly affected.
Most babies with gastroschisis have good long-term outcomes with appropriate neonatal and surgical care. Many eventually develop normal intestinal function, eat normally and participate in regular physical activities, although complicated cases can have longer-term gastrointestinal problems.
