Introduction
Gastroshiza is a rare congenital defect where a baby is born with part of the intestines, and sometimes other abdominal organs, outside the body. Unlike similar conditions, gastroshiza has no protective sac around the exposed organs, which makes immediate medical attention necessary. Over the years, medical advances have drastically improved survival rates, and today most infants recover successfully with proper treatment.
This article explores gastroshiza in detail covering its causes, risk factors, symptoms, diagnostic methods, treatment strategies, and long-term outcomes.
What is Gastroshiza?
Gastroshiza, also called gastroschisis in medical literature, is a developmental condition that occurs early in pregnancy. Normally, the abdominal wall closes during fetal growth, enclosing the intestines. In gastroshiza, the wall fails to close completely, leaving an opening usually to the right of the umbilical cord through which the intestines protrude.
This condition differs from omphalocele, another abdominal wall defect, because the intestines in gastroshiza are not covered by a membrane. That absence increases the risk of irritation, infection, and fluid loss.
Causes and Risk Factors of Gastroshiza
The precise cause of gastroshiza is still uncertain. However, research has identified several contributing factors:
-
Maternal Age: Teen mothers under 20 have a higher chance of delivering babies with gastroshiza.
-
Environmental Exposure: Contact with pesticides, chemicals, or harmful substances during pregnancy may raise risks.
-
Lifestyle Choices: Smoking, alcohol, or recreational drug use during early pregnancy can contribute.
-
Nutrition: Lack of essential nutrients such as folic acid may play a role.
-
Genetics: Although not considered a hereditary condition, some genetic tendencies could influence development.
It’s important to note that most cases of gastroshiza occur randomly, without any family history.
Signs and Symptoms of Gastroshiza
The most obvious sign of gastroshiza is visible at birth: the baby’s intestines protruding through an opening near the belly button. Additional complications may include:
-
Swollen or inflamed intestines due to exposure to amniotic fluid.
-
Feeding difficulties because of impaired intestinal function.
-
Intestinal blockages or twisting.
-
Fluid and electrolyte imbalance.
Because gastroshiza is usually detected before birth, doctors can prepare for immediate care at delivery.
Diagnosis of Gastroshiza
Modern prenatal care allows doctors to identify gastroshiza before birth. Common diagnostic approaches include:
-
Ultrasound Scan – Around the 18th to 20th week of pregnancy, ultrasounds can reveal intestines outside the fetus’s abdominal wall.
-
Blood Tests – High levels of alpha-fetoprotein (AFP) in the mother’s blood may suggest an abdominal wall defect.
-
Postnatal Examination – If not caught prenatally, gastroshiza is immediately noticeable after delivery.
Early detection is crucial because it allows healthcare teams to plan for specialized neonatal and surgical support.
Treatment for Gastroshiza
Surgery is the only way to treat gastroshiza, and the approach depends on the severity of the defect.
Primary Closure Surgery
If the intestines are healthy and not too swollen, doctors may immediately place them back into the abdominal cavity and close the wall.
Staged Repair (Silo Technique)
When intestines are too swollen to fit at once, surgeons use a special sterile pouch called a “silo.” The intestines are gradually moved back inside over several days or weeks before the opening is closed.
Aftercare and Recovery
Following surgery, infants need:
-
IV nutrition until the intestines can process food.
-
Antibiotics to prevent infection.
-
Close monitoring for complications such as bowel obstruction or feeding issues.
Possible Complications
Although treatment success rates are high, gastroshiza can sometimes lead to complications such as:
-
Intestinal obstruction due to scarring or twisting.
-
Long-term feeding difficulties.
-
Infections from exposed intestines before surgery.
-
Prolonged hospitalization in neonatal intensive care units (NICU).
However, with modern neonatal care, most infants recover well and live healthy lives.
Prognosis and Outlook
Today, more than 90% of babies born with gastroshiza survive after proper treatment. Long-term outcomes are generally positive, especially when surgery is performed quickly and successfully. While some children may experience digestive issues in early years, most eventually catch up with normal growth and development.
Prevention and Maternal Care
There is no guaranteed way to prevent gastroshiza, but mothers can lower risks by:
-
Avoiding smoking, alcohol, and drugs during pregnancy.
-
Maintaining good nutrition and taking prenatal vitamins with folic acid.
-
Seeking regular prenatal checkups and ultrasounds.
-
Reducing exposure to harmful chemicals or toxins.
Public health awareness and early prenatal care are essential in reducing complications linked to gastroshiza.
Conclusion
Gastroshiza is a rare but serious birth defect requiring immediate medical care. Though its exact cause remains unclear, early detection, advanced surgical techniques, and specialized neonatal care have transformed the prognosis for affected infants. With timely intervention, most children born with gastroshiza grow up to live normal, healthy lives.
By raising awareness and encouraging expectant mothers to follow safe pregnancy practices, the chances of complications can be reduced, giving newborns the best possible start in life.
