SubjectNCEBP 2: Evaluation of complex medical interventions
BACKGROUND: A positive symptom association probability (SAP) is regarded as an important selection criterion for antireflux surgery by many physicians. However, no data corroborate the relationship between symptom-reflux association and outcome, nor is it clear what impact a negative SAP has on the outcome of antireflux surgery in patients with abnormal oesophageal acid exposure. This study compared long-term outcomes of Nissen fundoplication in patients with a negative versus positive SAP. METHODS: Five-year outcome of Nissen fundoplication in patients with proton-pump inhibitor (PPI)-refractory reflux and pathological acid exposure was compared between those with (SAP+, 109) and without (SAP-, 29 patients) a positive symptom association. Symptoms, quality of life (QoL), PPI use, endoscopic findings, manometry and acid exposure were evaluated. RESULTS: At 5 years' follow-up, relief of reflux symptoms (95 versus 87 per cent), reduction in PPI use (80 to 25 per cent versus 85 to 14 per cent; P < 0.050) and improvement in QoL were similar in the SAP- and SAP+ groups. Reduction in acid exposure time (13.4 to 1.6 per cent versus 11.1 to 0.2 per cent of total time; P < 0.010), improvement in oesophagitis (44 to 6 per cent versus 61 to 13 per cent; P < 0.050) and increase in lower oesophageal sphincter pressure were also comparable. CONCLUSION: The subjective and objective outcomes of fundoplication in patients with pathological acid exposure are comparable among those with a positive and negative SAP. Patients with pathological acid exposure and a negative SAP can also benefit from antireflux surgery.
