BACKGROUND: Many investigators have proposed an association between gastro-oesophageal reflux disease and laryngo-pharyngeal symptoms, suggesting that medical or surgical therapy for reflux may be useful. AIM: To perform a meta-analysis assessing the effectiveness of medical or surgical therapy for reflux disease in adult patients with laryngeal or pharyngeal symptoms presumed to be due to gastro-oesophageal reflux disease. METHODS: Randomized controlled trials comparing medical or surgical treatments for gastro-oesophageal reflux disease against placebo were identified by searching MEDLINE (1966-September 2005), EMBASE (1974-September 2005), the CCRCT (until September 2005) and abstracts from gastroenterology and ENT meetings. The relative risks of reporting symptomatic improvement or resolution of symptoms was evaluated using a random-effects model. RESULTS: Five studies using high-dose proton pump inhibitor as intervention met the inclusion criteria and were included in the meta-analysis. No surgical studies met inclusion criteria. The pooled relative risk was 1.18 (95% confidence interval: 0.81-1.74). There was no heterogeneity between studies but evidence of significant publication bias. Sub-group analysis performed evaluating Jadad scores and symptom type, did not change the relative risk. CONCLUSIONS: Therapy with a high-dose proton pump inhibitor is no more effective than placebo in producing symptomatic improvement or resolution of laryngo-pharyngeal symptoms. Further studies are necessary to identify the characteristics of patients that may respond to proton pump inhibitor therapy.
