Prenatal Diagnosis of a Vanishing Gastroschisis With Subsequent Neonatal Bowel Complications: A Case Study

Background: Gastroschisis is a well-known birth defect in which bowel protrudes through a perforation in the fetal abdominal wall. High antenatal detection rates typically lead to good outcomes with modern neonatal treatments. Case: We describe a rare phenomenon in which gastroschisis appears to resolve antenatally, with associated bowel dilation and polyhydramnios. No evidence of an abdominal wall defect was seen at birth, but imaging was suggestive of bowel atresia. Surgical exploration showed a microcolon and most of the small bowel was absent. An extensive surgical repair was required, which resulted in short bowel syndrome. Conclusion: Gastroschisis that undergoes apparent resolution on sonography can be associated with necrosis due to strangulation of the exteriorized bowel and short bowel syndrome. This is associated with high neonatal morbidity and mortality.
