[Cryosurgery in the treatment of Echinococcus alveolaris. Animal experiments].

The influence of cryosurgery on echinococcus alveolaris is studied in 100 mice. In a second series cryosurgical effects on structures of the hepatic portal (hepatic artery, portal vein, hepatic duct) were examined. The experiments showed that echinococcus alveolaris can be devitalized by cryosurgical measures at temperatures between -100 degrees C and -190 degrees C. No damage of the hepatic artery, portal vein, and hepatic duct occurred. Clinical application of cryosurgery for the treatment of inoperable echinococcus alveolaris of the hepatic portal appears to be justified.
