Vanishing gastroschisis: Good outcome after a 10-year follow-up

Prenatal diagnosis of closed gastroschisis: What to expect in the most severe form of gastroschisis? Case report and literature review

Closed gastroschisis (CG) and vanishing gastroschisis (VG) are the most severe forms of evolution of the malformation. In this case, a fetus presented with gastroschisis at 13 weeks, and the gastroschisis was not visualized at 22 weeks of gestation. Distal ileum, cecum, and ascending colon atresia were diagnosed at surgery, and the child is fully enteral-fed at 5 months of age. In a literature review of 43 cases of prenatal diagnosis of CS-VG, intrauterine death occurred in 4.5% of cases. 79.6% of the cases underwent surgical treatment. Of these cases, 20% of cases died due to complications of treatment, 26% were still under treatment and 54% are alive with enteral feeding. In 77% of the cases, the closure of the umbilical ring occurred after 26 weeks of gestation and the absence of prenatal diagnosis of CG-VG during pregnancy has a risk of 71% of death.

Vanishing gastroschisis visualized by antenatal ultrasound: a case report and review of literature

We report a case of vanishing gastroschisis visualized by antenatal ultrasound with a 7-year long term follow-up. Currently, the child is still dependent on daily parenteral nutrition with no signs of hepatotoxicity. To our knowledge, it's the fourth case with a long-term follow-up. Vanishing gastroschisis is a rare complication of gastroschisis. However, physicians should be aware of it because its prognosis is worse than classical gastroschisis. When a vanishing gastroschisis is visualized or suspected by antenatal ultrasound, prenatal counseling is required with explanations about the risk of short bowel syndrome, the need of parenteral nutrition and related complications (inflammatory colitis, sepsis, liver failure and organ transplant). Mortality rate was initially around 93%, and dropped to 27% after the years 2000 (versus 10% for classical gastroschisis). After birth, all children will require surgery, and sometimes autologous gastro-intestinal reconstruction. Most survivors (68%) could be taken off the TPN. Unfortunately, long-term outcomes for children with vanishing gastroschisis are still missing in current literature.
