Abstract
Objectives: The sphincter of Oddi(SO) manometry via transpapillary route is performed usually for a period of several minutes. To investigate whether there is a considerable variation in the manometric measurements of SO over a longer period of time, we have performed long-term manometry of SO via transpapillary(n=5) as well as percutaneous(n=7) route. Methods: Transpapillary manometry of SO was carried out by conventional low- compliant continuously perfused techni~que. The location of the manometric catheter was maintained at the same level by observing the video monitor. SO manometry and the duodenal migrating motor complex(MMC) was simuitaneously measured with specially designed catheter via pereutaneous route. Results: The mean recording time was 41 minutes(range 11-72 minutes). The frequency of phasic contractions of SO varied from 0 to 12/min. Throughout the whole recording period, high-frequency contractians(over 8/min) were noted in 14.9 % of the time. In the eases of percutaneous transductal SO manometry, the periods of high-frequency contractions coincided with the phase III of duodenal MMC. The interval between the first high-frequency contractions and the second was 47 minutes. The mean duration of high-frequency contractions was 6 minutes and 4~2 seconds. There as no significant change in the amplitude, basal pressure and contraction sequence among the various periods of frequencies. Conclusions: Long-term continuous recording of SO manometry via transpapillary and percutaneous route showed that the contraction frequency of SO was not constant and tachyoddia appearde periodically. In the interpretation of tachyoddia, it is necessary to consider the period of phase III of the duodenal MMC. (Korean J Gastrointest Endosc 16; 443~448, 1996)
