Insights
This review covers gastroschisis (an abdominal wall defect) management. While most cases have good outcomes, about 15% are complex, requiring specialized care for survival.
Area of Science:
- Obstetrics and Gynecology
- Neonatal Surgery
- Fetal Medicine
Background:
- Gastroschisis, an abdominal wall defect, is increasing in frequency.
- Prenatal diagnosis is possible via ultrasonography and elevated maternal serum alpha-fetoprotein.
- Risk factors include ethnicity and maternal health, with increased risks for fetal growth restriction and demise.
Purpose of the Study:
- To review the evidence-based obstetrical management of gastroschisis.
- To identify antenatal predictors of neonatal outcomes.
- To outline current postnatal surgical strategies.
Main Methods:
- Evidence-based literature review.
- Analysis of studies on antenatal predictors.
- Review of surgical management techniques.
Main Results:
- Accurate prenatal prognosis remains challenging.
- Antenatal testing is recommended due to risks of growth restriction, amniotic fluid abnormalities, and fetal demise.
- Delivery by 37 weeks is generally advised, with cesarean delivery reserved for obstetric indications.
Conclusions:
- The majority of gastroschisis cases have a good prognosis with low long-term morbidity.
- Approximately 15% of cases are complex, involving complicated hospital courses and potential early childhood death.
- Postnatal management includes primary closure, staged reduction with silo, or sutureless umbilical closure.
Abstract:
We performed an evidence-based review of the obstetrical management of gastroschisis. Gastroschisis is an abdominal wall defect, which has increased in frequency in recent decades. There is variation of prevalence by ethnicity and several known maternal risk factors. Herniated intestinal loops lacking a covering membrane can be identified with prenatal ultrasonography, and maternal serum α-fetoprotein level is commonly elevated. Because of the increased risk for growth restriction, amniotic fluid abnormalities, and fetal demise, antenatal testing is generally recommended. While many studies have aimed to identify antenatal predictors of neonatal outcome, accurate prognosis remains challenging. Delivery by 37 weeks appears reasonable, with cesarean delivery reserved for obstetric indications. Postnatal surgical management includes primary surgical closure, staged reduction with silo, or sutureless umbilical closure. Overall prognosis is good with low long-term morbidity in the majority of cases, but approximately 15% of cases are very complex with complicated hospital course, extensive intestinal loss, and early childhood death.
