Gastroschisis: A Rare Birth Defect

Gastroschisis is a birth defect that occurs when an infant's intestines protrude outside the body through a hole in the abdominal wall, typically beside the belly button. This condition happens early during pregnancy when the baby's abdominal wall doesn't form correctly, leaving an opening for their organs to escape.

Characteristics of Gastroschisis

• The size of the hole can vary, and other organs such as the stomach and liver may also protrude outside the body.
• In some cases, the bowel outside the body is extremely damaged, twisted, or tangled.
• Complications may include feeding problems, prematurity, intestinal atresia, and intrauterine growth restriction.

Types of Gastroschisis

There are two types of gastroschisis: simple and complicated. Simple gastroschisis occurs when only the bowel protrudes outside the abdominal opening, while complicated gastroschisis involves damage to the bowel or other organs.

Prevalence of Gastroschisis

Gastroschisis is a relatively uncommon condition that occurs in approximately 1 in 5,000 live births. It is one of a group of birth defects known as abdominal wall defects, which occur very early in gestation and are characterized by an opening in the abdominal wall of the fetus.

Gastroschisis is a birth defect that causes a hole in the abdominal wall, allowing intestines to protrude outside the body. The signs and symptoms of gastroschisis can vary depending on the severity of the condition and the presence of any associated complications.

Common Signs and Symptoms:

• Dehydration: Babies with gastroschisis may experience excessive water loss due to the exposed intestines, leading to dehydration [1].
• Hypothermia: The exposed intestines can also cause a drop in body temperature, making it difficult for the baby to regulate their body heat [1].
• Decreased bowel movements: Babies with gastroschisis may have fewer bowel movements than usual due to the compromised intestinal function [5].
• Feeding problems: Gastroschisis can make it challenging for babies to feed properly, leading to issues such as vomiting or refusal to eat [5].
• Fever: Some babies with gastroschisis may develop a fever due to infection or inflammation related to the exposed intestines [5].
• Green or yellowish green vomit: The presence of bile in the vomit can be an indication of gastroschisis, as the intestines are not functioning properly [5].
• Swollen belly area: The protruding intestines can cause the abdominal area to appear swollen or distended [3].

Other Possible Symptoms:

• Vomiting: Babies with gastroschisis may experience vomiting, which can be different from normal baby vomit due to the presence of bile and other digestive enzymes [5].
• Swollen organs: In some cases, the exposed intestines can cause nearby organs, such as the liver or spleen, to become swollen or inflamed [6].

It's essential to note that not all babies with gastroschisis will exhibit these symptoms, and the severity of the condition can vary widely. Prenatal diagnosis is possible in some cases, but a definitive diagnosis is typically made after birth.

Diagnostic Tests for Gastroschisis

Gastroschisis, a congenital defect where the intestines protrude from the navel, can be diagnosed through various tests during pregnancy and after birth.

• Ultrasound: A highly detailed ultrasound is used to search for defects in the fetus. An ultrasound image of a fetus with gastroschisis shows loops of intestines floating outside the abdominal cavity [1].
• Blood Tests: Routine blood tests may show abnormally high alpha fetoprotein levels, which can lead to suspicion of gastroschisis [2].
• Prenatal Tests: Routine prenatal tests that check for birth defects in the baby are usually performed between 18 and 20 weeks of pregnancy. These tests include fetal echocardiogram (fetal echo) and other screenings [3][4].
• Physical Examination: A physical examination of the infant is sufficient to diagnose gastroschisis after birth, as the healthcare provider can see the protruding intestines [5].

These diagnostic tests are crucial in identifying gastroschisis during pregnancy and after birth, allowing for timely medical intervention.

Medications Used in Gastroschisis Treatment

Babies with gastroschisis often require various medications to manage their condition and prevent complications. Here are some common drug treatments used:

• Prophylactic antibiotics: These may be given preoperatively, especially if surgery for an associated intestinal anomaly is anticipated [2].
• Antibiotics: To prevent infection, antibiotics are commonly administered to babies with gastroschisis [4, 7, 9].
• Medications for comfort: Various medications may be used to manage pain and discomfort in babies with gastroschisis [4].

Other Medications Used

In addition to the above-mentioned medications, other treatments may include:

• Nutrients by IV: Babies with gastroschisis often require intravenous (IV) fluids and nutrients to support their nutritional needs [5, 9].
• Fluids and electrolytes: Careful management of fluid and electrolyte balance is crucial in babies with gastroschisis [7].

Important Notes

It's essential to note that the use of medications in gastroschisis treatment should be tailored to individual patient needs and under the guidance of a qualified healthcare professional.

Differential Diagnosis of Gastroschisis

Gastroschisis, a congenital defect of the abdominal wall, requires accurate diagnosis to differentiate it from other similar conditions. The differential diagnosis of gastroschisis includes:

• Omphalocele: A condition where the intestines and sometimes other organs protrude through the navel. Omphalocele is often confused with gastroschisis due to its similar presentation.
• Ruptured omphalocele: A complication of omphalocele where the sac surrounding the intestines ruptures, leading to intestinal injury.
• Limb-body wall complex: A rare congenital anomaly characterized by a combination of limb and body wall defects.
• Bladder exstrophy: A condition where the bladder is exposed outside the abdominal cavity due to a defect in the lower abdominal wall.
• Cloacal exstrophy: A rare congenital anomaly involving the cloaca, a shared opening for the reproductive, urinary, and digestive systems.

These conditions can be challenging to differentiate from gastroschisis, especially during prenatal diagnosis. Accurate diagnosis is crucial for proper management and treatment of these conditions.
