背景：最近报道的使用unissensor导管系统的高分辨率测压仪（HRM）获得的食管运动正常值与manscan获得的值明显不同（(R)），这可能导致错误的诊断。为了弄清这些差异是由于系统差异还是受试者差异造成的，我们比较了ManoScan和一种带有unissensor导管的新系统（Starlet）在相同受试者中的测压参数值。方法招募无食管运动障碍相关症状的志愿者103例。所有受试者均使用ManoScan和Starlet进行食管HRM。ManoScan的数据使用ManoView进行分析，Starlet的数据使用带有电子套筒功能的程序进行分析。采用两种分析程序计算综合松弛压力、远端收缩积分、收缩锋速度（CFV）、旋内压力和远端潜伏期，并通过符号秩检验比较两种系统的参数值。主要结果共分析了97名参与者的数据。除CFV外，Starlet测量的所有参数值均显著高于ManoScan测量的值(p
BackgroundRecently reported normal values for esophageal motility obtained by high-resolution manometry (HRM) using a system with a Unisensor catheter were significantly different from those obtained by the ManoScan((R)), which could result in a wrong diagnosis. To clarify whether these differences were due to system or subject differences, we compared the manometric parameter values between ManoScan and a new system with a Unisensor catheter (Starlet) in the same subjects.MethodsA total of 103 volunteers without any symptoms related to esophageal motility disorders were recruited. Esophageal HRM was performed using both the ManoScan and the Starlet in all subjects. Data from the ManoScan were analyzed using ManoView, and data from the Starlet were analyzed by a program with e-sleeve function. Integrated relaxation pressure, distal contractile integral, contractile front velocity (CFV), intrabolus pressure, and distal latency were calculated by both analyzing programs, and the values of these parameters were compared between the two systems by a signed rank test.Key ResultsData from a total of 97 participants were analyzed. The values of all parameters, except CFV, measured by the Starlet were significantly higher than those obtained by the ManoScan (p
