Abstract/OtherAbstract:
Although the motor function of the sphincter of Oddi (SO) has been clearly identified by endoscopic SO manometry (ESOM), the physiologic role of the phasic contractions of the SO remains unsettled in humans. The aim of this study was to correlate SO motor activity measured by ESOM with bile flow characteristics determined by simultaneously recorded endoscopic retrograde cinecholangiography. We investigated a 55-year-old female patient by means of ESOM. During the station pull-through recording, the ESOM catheter was withdrawn into the SO zone and retained there for 15 min. The pressures transmitted by the external transducers and the enlarged video picture of the choledochoduodenal junction from the X-ray fluoroscopic monitor (25 digital pictures/sec) were recorded simultaneously on the computer system with a time-correlated basis. During the analysis without taking note of the cinefluoroscopic events, we selected different manometric periods manually, such as the pressure wave of the SO phasic contraction, no SO phasic activity and the first second of the beginning of the next phasic contraction. Cumulative cinecholangiographic pictures were then constructed by the computer for each period, at a frequency of one frame/sec to create representative sum-of-pictures for each manometric period. By means of the application of manometrically gated cinecholangiography, we succeeded in demonstrating an exact time correlation between the SO systolic and diastolic movements on cinecholangiography and the pressure recording detected by ESOM in humans.
