[Hydrodynamic and radiologic examination of the common bile duct].

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.

[A study of atrio-ventricular conduction in subjects with the Lown-Ganong-Levine syndrome (author's transl)].

Eight subjects with the Lown-Ganong-Levine syndrome were studied by means of His bundle recordings during sinus rhythm and during atrial pacing. During sinus rhythm in all cases, the A-H interval was lesser than the mean value observed in 10 control subjects. Atrial pacing at rates up to 190/min produced three types of responses. Four patients showed an initial increment in A-H interval, followed by a plateau response at higher rates. One patient showed an initial increment and a plateau response in A-H interval at low and intermediate rates, followed by a sudden and conspicuous increment at higher rates, indicating conduction of impulse through the A-V node, due to refractoriness of the by-pass tract. Three patients showed a progressive increase in A-H interval similar to that of normal subjects but to a lesser degree. The possible mechanisms for the different types of response are discussed.
