Jejunal obstruction as a late result of neonatal jejunal atresia.

The authors report on two adults who had jejunal dilatation after having had resection for jejunal atresia in the neonatal period. Both patients presented 20 years after the initial procedure, with severe iron deficiency anemia, marked jejunal dilatation proximal to the old anastomotic site (which was not narrowed), and a bezoar within the dilated segment. Upper gastrointestinal series were used to evaluate both patients before surgical resection of the enlarged intestine, with subsequent correction of the anemia.
