Ambulatory recording of antroduodenal manometry is a novel technique with several advantages over standard stationary manometry recording. Although the feasibility of this technique in clinical practice has been demonstrated, reproducibility of antroduodenal motility recorded by means of ambulatory manometry has not been investigated. To test whether antroduodenal motility recorded by ambulatory manometry is reproducible, we performed two 24-h ambulatory antroduodenal manometry recordings in 18 healthy subjects according to an identical protocol with a 1-week interval. Motility was recorded with a five-channel solid-state catheter. Postprandial motility was recorded after consumption of two test meals and interdigestive motility was recorded nocturnally. Postprandial antroduodenal motor characteristics were identical between the separate recordings. The number and duration of nocturnal cycles of the interdigestive migrating motor complex were also in the same range. Phase III characteristics in general were not different between the two recordings. Only minor alterations were observed in the duration of phase III motor fronts with duodenal onset and in the number of interdigestive cycles concluded by duodenal onset phase III. Parameters obtained by qualitative analysis were comparable between the two recordings. The antroduodenal motility pattern, when measured by ambulatory recording with solid state catheters under standardized conditions, is very reproducible.
动态十二指肠测压记录是一种新技术，与标准的静态测压记录相比具有多个优点。尽管该技术在临床实践中的可行性已得到证实，但通过动态测压记录的十二指肠动力的可重复性尚未得到研究。为了测试通过动态测压记录的十二指肠动力是否具有可重复性，我们按照相同方案，在18名健康受试者中进行了两次24小时动态十二指肠测压记录，间隔为1周。使用五通道固态导管记录动力。餐后动力在摄入两份测试餐后记录，消化间期动力在夜间记录。两次单独记录之间的餐后十二指肠运动特征相同。消化间期移行性运动复合波的夜间周期数量和持续时间也在相同范围内。总体而言，两次记录之间的III期特征没有差异。仅在十二指肠起始的III期运动前沿的持续时间以及以十二指肠起始III期结束的消化间期周期数量方面观察到微小变化。通过定性分析获得的参数在两次记录之间具有可比性。在标准化条件下使用固态导管进行动态记录时，十二指肠动力模式具有很高的可重复性。
