Three- to 4.5-Year Prospective Study of Prognostic Indicators in Gastro-oesophageal Reflux Disease
1998
Background: Data on the long-term natural history of gastro-oesophageal reflux disease (GORD) are sparse. This prospective study was designed to determine the clinical outcome on the basis of therapeutic requirements 3 to 4.5 years after initial diagnosis of GORD and to identify specific prognostic indicators of a poor outcome. Methods: One hundred and one GORD patients were followed up by symptomatic questionnaire 3 to 4.5 years after diagnosis and offered repeat investigation with endoscopy and oesophageal pH monitoring if symptoms persisted. Results: Seventy-seven (76%) patients responded (mean follow-up period, 39 months; range, 32-54 months); of these, 28 had grade-II or -III oesophagitis at initial endoscopy, 17 had normal endoscopy but abnormal pH monitoring, and 32 had normal investigations but frequent heartburn. At follow-up 32 (42%) were taking acid suppression therapy, and a further 15 patients started acid suppression therapy after repeat investigation indicated a need to do so, giving a tota...
