BACKGROUND: Wireless oesophageal (Bravo) readings in healthy European and American subjects show varied results. Values in Asians remain unstudied. AIMS: We performed Bravo studies in healthy Asians to determine if values differed from previously published and identified reflux parameters to differentiate healthy volunteers from patients. METHODS: Fifty healthy volunteers were recruited between August 2009 and August 2011 to undergo 48h wireless pH monitoring. Bravo capsule was introduced transorally and placed 6cm above the squamocolumnar junction. Acid reflux parameters were compared against 41 patients previously evaluated for non-erosive reflux disease. RESULTS: Five volunteers were excluded. Capsule dislodgement occurred in four and three volunteers on study days 1 and 2 respectively. Forty and 37 volunteers (73% male, mean age 33.0±7.6 years) had interpretable readings at 24 and 48h, respectively. Percentage of time oesophageal pH<4 in 37 volunteers who completed 48h recordings was 1.6% (7.5%), 1.5% (6.3%) and 1.9% (5.8%) on days 1, 2 and overall study duration, respectively. CONCLUSION: Bravo readings in Asians differed from previously published. Percentage of time oesophageal pH<4 on day 2 and DeMeester score on day 2 (95th percentile 22.9) best discriminated healthy volunteers from patients.
