RESUMO
The experimental study of liver cirrhosis with portal hypertension syndrome, modeled in 38 dogs, has been performed. Surgical treatment aimed on the portal decompression consisted of the implantation of the Celsite port-system. The reliable portal pressure decrease was observed in the first week of the experiment (from 269.3±17.8 to 157.4±26.5 millimeter of water). Portal decompression reasonably led to the improvement of the general state of the animals.

Treatment results of 54 patients with liver cirrhosis and portal hypertension, complicated by diuretic-resistant ascites, were analyzed. Peritoneal port-system was implanted in 12 cases, the rest 42 patients had peritoneovenous bypass with the use of Levine's valve. Port-system implantation was possible in patients with contraindications for bypass, such as low central venous and intraabdominal pressure gradient, chylous ascites, ventral hernias etc. The use of peritoneal ports provides fractional reinfusion af the ascetic fluid, which excludes such complications as hemodilution and coagulopathy.

The results of surgical treatment of 628 patients aged 15-76 years operated on for echinococcosis of diaphragmatic surface of the liver have been analysed for period from 1976 to 1996. 333 patients had complicated echinococcosis, 124 combined pathology of other organs. Methods which have been applied for diagnosis of echinococcosis of the liver and its complications are described. Details of surgical treatment of the echinococcosis of the diaphragmatic surface of the liver are elucidated in time course aspects, as a staged treatment, during which various factors were used for antiparasitic treatment of cystic cavity as well as various methods of elimination of the residual cavity. Problems concerning application of laser and plasmatic scalpel during various stages of the operation, as well as low-intensity lasers and low-frequency ultrasound during the operation and in postoperative period are considered. Postoperative complications were detected in 99 (15.8%) patients, lethal outcomes were in 5 (0.8%) cases.
