The operative study of the common bile duct was carried out with the hydrodynamics methods (flow and resting pressure) in 433 patients and with the operative cholangiography in 383 patients. The hydrodynamics explorations pointed-out a margin of mistake due to falses positives and negatives of the 2.7% and the operative cholangiographies of the 8.6%. The association of both methods, hydrodynamics and radiologycs, allowed us to estimate that the diagnostic mistake is reduced to 0%. It is established in this work the necessity of carring out the flow, the measure of the resting pressure and the cholangiographies; in all the patients that are operated on the biliary tract because the diagnostic accuracy is the 100%. It is discussed the value of the diameter of the common bile duct for affirming the eventual existence of obstruction of the lower part of the common bile duct and the values are correlated, measured in mm., with pathological founds. It is considered the value of the hydrodynamics methods in the diagnostic of the stenosis of the sphincter of Oddi.
对433例患者采用流体动力学方法（流量和静息压力）进行胆总管手术研究，对383例患者进行手术胆管造影。流体动力学探查指出，由于假阳性和假阴性，其误差率为2.7%，手术胆管造影的误差率为8.6%。流体动力学和放射学这两种方法相结合，使我们估计诊断错误率降至0%。本研究确定了对所有接受胆道手术的患者进行流量测定、静息压力测量和胆管造影的必要性，因为诊断准确率为100%。讨论了胆总管直径对于确定胆总管下段是否存在梗阻的价值，并将以毫米为单位测量的值与病理结果相关联。还考虑了流体动力学方法在诊断Oddi括约肌狭窄中的价值。
