Abstract To assess the prevalence of antenatal diagnosis of small-intestinal atresias (SIA) in the modern era and determine its effect on management and outcome, the records of neonates admitted to a single institution in 1991–1996 with a diagnosis of SIA were reviewed. Duodenal atresia, atresias complicating meconium ileus, and those associated with gastroschisis were excluded. Of 14 neonates with SIA, 10 had jejunal atresia (JA) (Grosfeld type I, n = 1; type II, n = 2; type IIIa, n = 3; type IIIb [apple peel], n = 3; type IV, n = 1) and 4 had ileal atresia (IA) (type II, n = 1; type IIIa, n = 3). Antenatal diagnosis was made in 4 neonates (overall rate = 28%), including all 3 type IIIb JA, and 1 type II JA. None of the IAs were diagnosed antenatally. There were 2 deaths, both in patients with high JAs with less than 10 cm viable bowel. Only 1 of these was antenatally diagnosed. The median (range) times to full enteral feeding were 20 days (17–22) for antenatally-diagnosed JA, 14 days (11–26) for other JAs, and 8 days (6–15) for IAs. Antenatal diagnosis of SIA thus remains relatively infrequent (less than one-third of cases). When an antenatal diagnosis is made, the atresia is more likely to be proximal in location, requiring intensive and prolonged postnatal treatment. Provided a reasonable length of bowel remains, the outcome of SIA, whether antenatally diagnosed or not, is favorable.
