Symptomatic annular pancreas in newborns.

Abstract

Infants with annular pancreas associated with duodenal obstruction are generally premature or small for their gestational age. The symptoms observed in annular pancreas are related not only to extrinsic compression of the ectopic tissue, but also the duodenal stenosis associated with this malformation. Annular pancreas is most commonly associated with intestinal malrotation. It does not correlate as strongly with trisomy 21 karyotype as do the duodenal atresias, and oral feeding tolerance time is nearly the same between the DD and DD+TE+TJT groups.
