Background Few data are available comparing intragastric pH measured with the traditional catheter-based and the more recent wireless system (Bravo), and also comparing intraesophageal and intragastric pH during reflux events. Aims of our study were to elucidate these points. Methods Eleven subjects with functional dyspepsia underwent placement of a Bravo capsule 9cm below the squamo-columnar junction (SCJ) and of a dual-electrode catheter, so that the distal electrode was located 9cm below and the proximal one 6cm above the SCJ. Key Results The wireless system showed lower intragastric pH than the traditional catheter in the postprandial period (median 2.2 wireless vs 2.7 catheter, P
