METHODS: A study of all patients with significant GOER seen at the Paediatric Gastroenterology Unit, Queen Elizabeth Hospital for Children, Hackney Road, London, between December 1994 and August 1995.
RESULTS: The median age at referral was 16 months. Presenting symptoms were recurrent vomiting (72%), epigastric and abdominal pain (36%), feeding difficulties (29%), failure to thrive (28%) and irritability (19%). Continuous 24-h lower oesophageal pH studies performed in 57 children showed 20 (35%) had a reflux index of between 10% to 20%, 14 (25%) had a index > 20%, and six (11%) had a postprandial reflux index > 10%. Reflux was shown in 38 (62%) of 62 children who underwent barium studies. None had significant anatomical abnormalities, but in the 22 children who had a negative barium studies, six had severe reflux (reflux index > 20%). Upper gastrointestinal endoscopy performed in 47 children showed reflux oesophagitis in 29 (62%), oesophageal ulceration in three, and Barrett's oesophagus in one. All of the children were treated with standard medical therapy. Sixty-six per cent were able to discontinue medication within 12 months and remained well. Four children (6%) required Nissen's fundoplication for failure to respond to medical therapy.
CONCLUSIONS: Most infants with GOER have an uncomplicated course. False negative results were noted in both pH monitoring and barium meal. Up to 80% of children, with therapy, will improve within 12 months.
