A case of Pierre-Robin syndrome associated with gastroesophageal reflux and oesophagitis is described. The infant was firstly fed with a hydrolysed-casein formula by gastrostomy, but there was not any improvement of his clinical status, in spite of an appropriate nutrient intake. For this reason, a jejunal enteral feeding, with a semi-elemental formula and then with a hydrolysed-casein formula was started. During this nutritional treatment, the infant showed an adequate weight gain and after 52 days the weight increased from 2880 g to 4580 g.
