Esophageal atresia or tracheoesophageal fistula (EA/TEF) often occurs in as
sociation with a well-defined group of other anomalies. We report the preva
lence of malrotation and other intestinal anomalies in a large data series
comprising 632 nontrisomic infants with EA/TEF ascertained by the Californi
a Birth Defects Monitoring Program from January 1, 1983 to December 31, 199
4. Consistent with findings reported previously in smaller case series, our
findings showed a notable prevalence of imperforate anus (9.0%) and duoden
al atresia (5.2%), among other gastrointestinal defects. They also showed a
previously unrecognized high prevalence of intestinal malrotation (4.4%).
Compared with other infants studied, the infants with EA/TEF and malrotatio
n of the intestine had a higher proportion of other associated anomalies (i
n particular intestinal, central nervous system, vertebral and rib, renal a
nd genital anomalies). These findings indicate that intestinal malrotation
is more common in infants with EA/TEF than is generally perceived, and that
intestinal malrotation in an infant with EA/TEF is associated with a highe
r burden of additional congenital anomalies, suggesting that this group of
infants may have more pervasive developmental deficits and poorer prognosis
than has previously been recognized. Teratology 60:114-116, 1999. (C) 1999
