Surgery for gastro-oesophageal reflux

Gastro-oesophageal reflux: clinical profiles and outcome

OBJECTIVES

To assess the clinical features, investigations and outcome of 69 children (40 males, 29 females) with gastro-oesophageal reflux (GOER) referred to a tertiary referral centre in paediatric gastroenterology.

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.

Gastrooesophageal reflux in children with cerebral palsy

Feeding difficulties, vomiting and recurrent chest infections associated with poor growth and nutrition are common in children with cerebral palsy (CP). However, the role of gastrooesophageal reflux as a possible cause has been little studied. We therefore investigated 23 children with cerebral palsy (median age 2.3 years, range 0.6-11.8) whose symptoms were consistent with gastrooesophageal reflux (severe feeding difficulties 70%, failure to thrive 52%, anaemia 31% and recurrent chest infections 31%). Using 24-hour ambulatory oesophageal pH monitoring, we determined the relationship between gastrooesophageal reflux and: (a) developmental age (Griffith's scales); (b) feeding behaviour skills score; (c) nutritional status and (d) clinical assessment of cerebral palsy (type and severity). Abnormal gastrooesophageal reflux (i.e. reflux index > 5%) was detected in 16 (70%) patients (median reflux index 11.4%; range 5.4-59%). Reflux was unrelated to chronological or developmental age, but there was a significant, unexplained association with male gender (P < 0.01). No correlation was found with feeding behaviour skills score, malnutrition (which was commonly severe) and type and severity of cerebral palsy. We conclude that gastrooesophageal reflux is common and should be sought in symptomatic, neurologically handicapped children as effective treatment is likely to improve quality of life.

Treatment of refractory ulcerative oesophagitis with omeprazole

A 7 year old boy with ulcerative oesophagitis failed to respond to a two month course of intensive medical treatment using H2 receptor antagonist treatment in combination with domperidone and sucralfate. He demonstrated complete resolution using omeprazole 10 mg once a day for eight weeks.
