Abstract
Background: Approximately 10 per cent of patients referred for 24-h oesophageal pH tests with symptoms suggestive of gastro-oesophageal reflux disease will have a normal endoscopic examination and normal distal oesophageal acid exposure times, but a clear temporal correlation between their symptoms and episodes of acid reflux. These patients have an ‘acid-sensitive oesophagus’, which forms part of the spectrum of reflux-related conditions. Their response to antireflux surgery has not been reported previously. This study represents a prospective cohort analysis of a clearly defined group of patients with acid-sensitive oesophagus who have undergone laparoscopic antireflux surgery. Methods: Nineteen patients (nine male and ten female; median age 32 years) underwent laparoscopic antireflux surgery for acid-sensitive oesophagus. All had had an incomplete response to medical therapy. Results: Eighteen of 19 patients were graded Visick I or II at 6 months after operation; all 16 patients followed for 1 year were graded Visick I or II. There were significant falls in DeMeester symptom score (4·0 versus 0·5; P < 0·001), symptom events (20 versus none; P < 0·001), number of reflux episodes (17 versus two; P < 0·001) and overall acid exposure times (1·2 versus 0·3 per cent; P < 0·001) after operation. Conclusion: Laparoscopic antireflux surgery is a valid and effective treatment for patients with an acid-sensitive oesophagus.
