The correction method of portal hypertension, basing on the blood circulation flow reduction in the main abdominal cavity arterial vessels, was elaborated in experiments on dogs. The functional and morphological changes in vascular bed and the abdominal cavity organs after the portal hypertension modelling and its surgical correction were studied up.

The proposed method of common biliary duct cannulation is simple, easily performed and permits studying bile hydrodynamics biligenesis for a necessary time. Tightness of the system is completely preserved after removal a choledochostomical tube. Walls of the invaginated stump of the cystic duct are swiftly abated as a result of hydrostatic pressure and cover its gap. The presence of purse string kapron suture in a stump orifice creates an obstacle to deinvagination. Good reparation properties of serous and subserous membranes, covering the biliary duct, promote rapid closing of stoma. Effectiveness of the proposed method of common biliary duct cannulation by means of the invaginated stump of the cystic duct is confirmed by the smooth postoperative course and absence of a biliary fistula after the tube removal.

In the experiment performed on 107 dogs, after resection of 33-75% of the pulmonary volume, it has been stated that considerable disturbances take place in the myocardial microcirculatory bed. At early stage after the operation the amount of capillaries per 1 mm2 of the section increases, their lumens become wide. With elapse of time after the operation, as a result of myocardial hypertrophy, density in arrangement of the capillaries decreases, and the transversal section area of the cardiomyocyte per one capillary increases. In the capillary walls destructive changes are also noted; they result in myocardiodistrophy and in development of cardiac failure.
