PURPOSE:

The purpose of this study is to evaluate (1) the predictive value of fetal bowel dilatation (FBD) for intestinal atresia in Gastroschisis and (2) the postnatal management and outcome of this condition.

METHODS:

A retrospective review of all gastroschisis cases diagnosed in our fetal medicine unit between 1992 and 2010 and treated postnatally in our center was performed.

RESULTS:

One hundred thirty cases had full postnatal data available. Intestinal atresia was found at surgery in 14 neonates (jejunum, n = 6; ileum, n = 3; ascending colon, n = 3; multiple, n = 2). Polyhydramnios and FBD were more likely in the atresia group compared with infants with no atresia (P = .0003 and P = .005, respectively). Fetal bowel dilatation had 99% negative predictive value (95% confidence interval, 0.9-0.99) and 17% positive predictive value (95% confidence interval, 0.1-0.3) for atresia. treatment of intestinal atresia included primary anastomosis (n = 5), delayed anastomosis (n = 2), and stoma formation followed by anastomosis (n = 7). Infants with atresia had longer duration of parenteral nutrition, higher incidence of sepsis, and cholestasis compared with infants with no atresia (P = .0003). However, the presence of atresia did not increase mortality.

CONCLUSIONS:

Polyhydramnios and FBD are associated with atresia. Absence of FBD in gastroschisis excludes intestinal atresia. In our experience, atresia is associated with a longer duration of parenteral nutrition but does not influence mortality. These findings may be relevant for antenatal counseling.
