Fetal abnormalities » Gastrointestinal tract
- 1 in 3,000 births
- Presence of intra-abdominal hyperechogenic areas (peritoneal calcifications). Results from intrauterine perforation of the bowel which leads to a local sterile chemical peritonitis.
- Additionally: dilated bowel loops, ascites and meconium pseudocyst.
- The incidence of chromosomal abnormalities and genetic syndroms is not increased.
- Risk of cystic fibrosis: 75%.
- Detailed ultrasound examination.
- Amniocentesis: DNA studies for cystic fibrosis if both parents are carriers.
- TORCH test for fetal infections
- Ultrasound scans every 4 weeks to monitor the evolution of the condition.
- Place: hospital with neonatal intensive care and pediatric surgery.
- Time: 38 weeks.
- Method: induction of labor aiming for vaginal delivery.
- In case of simple peritonitis the outcome is good and surgical intervention is not necessary.
- In case of complex peritonitis (associated with bowel dilatation, ascites) the prognosis is poor and neonatal mortality is >50%.
- Isolated: no increased risk of recurrence.
