N2 - We have compared the sphinctometer with the water-perfused sleeve (gold standard) for measurement of lower oesophageal sphincter (LOS) characteristics by simultaneous recording. LOS pressure and transient LOS relaxations (TLOSR) measured by sleeve and sphinctometer in 11 healthy volunteers showed identical patterns. However, output of the sphinctometer was significantly (P <0.01) lower than output of the sleeve. A total of 249 TLOSR were recorded. Of these, 176 TLOSR were identified by both sleeve and sphinctometer, 50 TLOSR were identified by sleeve alone and 23 TLOSR by sphinctometer alone. Due to the lower pressure output of the sphinctometer, 29 LOS relaxations did not reach criteria to qualify as TLOSRs. When TLOSR criteria were adjusted for sphinctometer pressure measurements, the number of TLOSRs identified by both sleeve and sphinctometer increased from 176 to 205. In conclusion, in healthy volunteers the sphinctometer registers TLOSR with results comparable with sleeve recording. However at low LOS pressures, the number of TLOSR is underscored by the sphinctometer.
