Lactobezoar in the low-birth-weight infant.

Lactobezoar is an unusual complication associated with infant feeding. Seven low-birth-weight infants developed lactobezoars, including one whose case was complicated by gastric perforation. Six of these infants were fed formulas specifically designed for the low-birth-weight infant. Abdominal distention or regurgitation were the most frequent symptoms. The diagnosis was confirmed or made prospectively on supine or cross table lateral chest roentgenograms that included the upper abdomen. Treatment consisted of withholding feeding for 24 hours. There was no recurrence of symptoms following resumption of feedings.
