SPHINCTER OF ODDI MOTILITY IN PATIENTS WITH BILE-DUCT STONES - A COMPARATIVE-STUDY USING PERCUTANEOUS TRANSHEPATIC MANOMETRY

The motility of the sphincter of Oddi was measured by percutaneous tra nshepatic manometry of the sphincter of Oddi (PTMSO) in three groups o f 57 patients with bile duct stones. The three groups were: (1) cholec ystectomy group (N = 10)-patients with common bile duct stones (CBDS) who had already undergone cholecystectomy; (2) noncholecystectomy grou p (N = 37)-patients with CBDS who had not undergone cholecystectomy; a nd (3) intrahepatic stone (IHS) group (N = 10). The basal pressure, am plitude, frequency, and propagation direction of contraction waves and the response to cerulein injection or dried egg yolk ingestion were a nalyzed and compared among these groups. No significant differences in the basal pressure, amplitude, frequency, and propagation direction o f the contraction waves were found among the three groups. There were also no differences in the response to cerulein or dried egg yolk inge stion. The frequency and duration of the burst contractions occurring in duodenal phase III of the migrating motor complex were significantl y higher (P < 0.05) in the cholecystectomy group than in the other two groups. These two differences in the burst contractions may be ascrib ed to the absence of the gallbladder.
