[Secretory pressure of the liver and bile hydrodynamics in prolonged obstruction of the bile ducts].

It is established in the experiment, that in stable obturation of the cystic and common bile ducts, the biliary pressure increases to the level of secretory hepatic pressure, at which it maintains for 9 days. Beginning from the day 10 of obturation, the common bile duct pressure sharply decreases (P less than 0.01) and remains decreased up to the end of investigation (day 27). The author distinguishes the periods of increase and stabilization of the pressure, stable hypertension, stable decrease of the pressure. The first two periods are indicative of compensation of the secretory function, the third one--of its decompensation.
