Gastroschisis and omphalocele: prenatal diagnosis and perinatal management
Insights
Prenatal diagnosis of gastroschisis and omphalocele is common with obstetric ultrasonography. Vaginal delivery outcomes for infants with these conditions are acceptable, contrary to recent trends favoring cesarean sections.
Area of Science:
- Perinatal medicine
- Diagnostic imaging
- Fetal surgery
Background:
- Obstetric ultrasonography has increased the prenatal diagnosis rate of gastroschisis and omphalocele.
- Omphalocele diagnosis raises concerns for concomitant abnormalities, including trisomies, necessitating thorough evaluation.
- Current perinatal practices often favor cesarean sections for these conditions without strong evidence of improved outcomes.
Purpose of the Study:
- To review the ultrasonographic features of gastroschisis and omphalocele.
- To evaluate the outcomes of vaginal versus cesarean section delivery for infants diagnosed with gastroschisis or omphalocele.
- To assess the scientific evidence supporting current delivery approaches.
Main Methods:
- Presentation of illustrative cases.
- Comprehensive review of the ultrasonographic features associated with gastroschisis and omphalocele.
- Literature review and analysis of existing data on delivery methods and infant outcomes.
Main Results:
- Ultrasonography is effective for prenatal diagnosis of gastroschisis and omphalocele.
- Infants with omphalocele require full evaluation due to associated risks.
- Data suggests acceptable outcomes for infants delivered vaginally, challenging the trend towards cesarean sections.
Conclusions:
- Prenatal diagnosis of abdominal wall defects is facilitated by obstetric ultrasound.
- Vaginal delivery appears to be a viable and acceptable option for affected infants.
- Further prospective studies are required to definitively compare delivery outcomes.
Abstract:
Obstetric ultrasonography has made the prenatal diagnosis of gastroschisis and omphalocele more common. We present illustrative cases and review the ultrasonographic features. Because of the increased risk of concomitant abnormalities (including trisomies) with omphalocele, full evaluation is indicated when this diagnosis is suspected. Recent perinatal approaches to delivery have favoured caesarean section, without scientific evidence that outcome is improved. Our experience, as well as a review of the literature, suggests that the outcome for vaginally delivered infants is acceptable. A prospective study of this question is needed.
