Barium impaction as a cause of small bowel obstruction in an infant with cystic fibrosis.

Small bowel obstruction in children with cystic fibrosis due to the impaction of barium is an unusual occurrence. This is the report of an 8.5-month-old black male who had an upper GI series on the day of discharge from the hospital, and returned the next day with a distal small bowel obstruction due to a barium impaction.
