Upper GI contrast for malrotation

A retrospective review of 166 neonates with bilious vomiting who underwent an upper gastrointestinal contrast study showed that only 14 (9%) had malrotation (confirmed at laparotomy). Of infants referred in the first three days of life, less than 1% had malrotation while 23% of infants referred after three days had malrotation. The number of  upper GI contrast studies performed to exclude one malrotation was 13 in the earlier period and 18 in the most recent period, suggesting increasing referrals of infants for testing.
