Our aim was to establish normal values for wave characteristics and patterns in long-term ambulatory oesophageal body motility.
A pressure sensor was positioned in the pharynx or cricopharyngeus for swallow detection. Oesophageal body pressures were recorded 5, 10, and 15 cm above the lower oesophageal sphincter. Contraction patterns and wave characteristics from eating, drinking, and postprandial, fasting, and supine periods in 16 healthy subjects were studied.
Contraction patterns were similar during eating and drinking periods or fasting and postprandial periods (P > 0.05). Wave characteristics during each period differed significantly in amplitude, duration, area under the curve, or peristaltic velocity (P < 0.05). During the eating period the amplitude and area under the curve were greatest, and peristaltic velocity was slowest compared with all other periods.
Data from the eating and drinking periods or the fasting and postprandial periods can be combined for contraction pattern analysis but not for wave characteristic analysis, for which data from different periods should be analysed separately.
我们的目的是建立长期动态食管体部运动的波形特征和模式的正常值。
将压力传感器置于咽部或环咽肌处以检测吞咽。在食管下括约肌上方5厘米、10厘米和15厘米处记录食管体部压力。研究了16名健康受试者在进食、饮水、餐后、禁食和仰卧位期间的收缩模式和波形特征。
进食和饮水期间或禁食和餐后期间的收缩模式相似（P>0.05）。各时期的波形特征在振幅、持续时间、曲线下面积或蠕动速度方面存在显著差异（P<0.05）。与所有其他时期相比，进食期间的振幅和曲线下面积最大，蠕动速度最慢。
进食和饮水期间或禁食和餐后期间的数据可合并用于收缩模式分析，但不能用于波形特征分析，波形特征分析的数据应分别分析不同时期的数据。
