Abstract

To assess the reproducibility of Sphincter of Oddi(SO) manometry, percutaneous manometry of SO was performed repeatedly in 10 subjects with biliary diseases(9 intrahepatic stone cases and 1 bile duct cancer case). Time interval for measurement of SO manometry was 3 to 7(mean 5) days. Mean manometric parameters of SO phasic contraction in the 1st and 2nd studies were not significantly different. However, as a result of manometric records, a diagnosis of dyskinesia was made in the 1st study from 4 patients(tachyoddia in 3 cases and increased retrograde propagation in one case). Among them, the diagnosis was reproduced in the 2nd study from 2(tachyoddia in 2 cases) out of 4 patients. In conclusion, abnormal manometric findings were poorly reproducible. Thus, more prolonged measurement of SO manometry or a dynamic test which stimuli or inhibit the SO activity may be necessary for accurate diagnosis of biliary dyskinesia and better reproducibility of SO manometry.
