The effect of antenatal diagnosis on the management of small bowel atresia

The aim of this study was to determine whether babies with small bowel atresia (SBA) diagnosed antenatally followed a different course from those diagnosed postnatally. We reviewed the records of neonates admitted to a single institution between 1985 and 2000 with a diagnosis of SBA. Thirty-nine neonates presented with SBA, with antenatal diagnosis (AND) being made in 12 (31%). There was no difference between the AND and postnatal diagnosis (PND) groups in terms of gestational age at birth, but the AND group had a lower mean birth weight. The babies in the AND group were operated on more quickly than those in the PND group. Ten out of 12 (83%) AND patients required parenteral nutrition compared with 12 out of 27 (44%) in the PND group, and the AND group had a significantly longer mean length of stay and spent a longer time on parenteral nutrition than the PND group.
