Gastroschisis

Definition

Gastroschisis is a birth defect in which an infant's intestines stick out of the body through a defect on one side of the umbilical cord.

Causes

Gastroschisis is a type of hernia. Hernia means "rupture." Babies with this condition have a hole in the abdominal wall, usually on the right side of the umbilical cord. The child's intestines can be easily seen.

The condition is similar to an omphalocele in appearance. An omphalocele, however, is a birth defect in which the infant's intestine or other abdominal organs stick out of the umbilical cord (belly button area).

Symptoms

• Lump in the abdomen
• Intestine protruding through the abdominal wall near the umbilical cord (navel)
• Gut motility and absorption affected due to the unprotected intestine being exposed to irritating amniotic fluid

Fortunately, other associated congenital defects are rare in patients with gastroschisis.

Exams and Tests

Physical examination of the infant is sufficient for the health care provider to diagnose gastroschisis. The mother may have shown signs indicating excessive amniotic fluid (polyhydramnios). Prenatal ultrasonography often identifies the gastroschisis.

Treatment

If identified before birth, mothers with gastroschisis need special monitoring to make sure the unborn baby remains and healthy. Plans should be made for careful delivery and immediate management of the problem after birth.

Treatment for gastroschisis is surgery. A surgeon will put the bowel back into the abdomen and close the defect, if possible. If the abdominal cavity is too small, a mesh sack is stitched around the borders of the defect and the edges of the defect are pulled up. Over time, the herniated intestine falls back into the abdominal cavity, and the defect can be closed.

Other treatments for the baby include nutrients by IV and antibiotics to prevent infection. The baby's temperature must be carefully controlled, since the exposed intestine allows a lot of body heat to escape.

Outlook (Prognosis)

Likelihood of recovery is good if the abdominal cavity is relatively large enough. A very small abdominal cavity may result in complications requiring additional surgery.

Possible Complications

• Respiratory distress (the misplaced abdominal contents can cause difficulty with expansion of the lungs)
• Bowel death (necrosis)

When to Contact a Medical Professional

This condition is apparent at birth and will be detected in the hospital at delivery. It may also be detected on routine fetal ultrasound exams. If you have given birth at home and your baby appears to have this defect, go to the emergency room or call the local emergency number (such as 911) immediately.
