Abstract: | In seven patients operated on with cholecystectomy for simple gallstones, sphincter of Oddi manometry was performed during surgery. The sphincter was localized as a zone with elevated base-line pressure and phasic contractile activity. Mean value of the amplitude was 90 mm Hg; wave duration, 4 sec; frequency, 5/min; and base-line pressure, 10 mm Hg. No activity was seen in the antrum or duodenum. The plotting of peak-to-peak intervals in a histogram showed that these were evenly distributed around 6 sec or at integrated multiples of this value. This indicates that the sphincter of Oddi is paced. The origin of the pacing is not yet established. |
