[Causes for liver echinococcosis reccurence].
Recurrence of the liver echinococcosis is established in 22,30% of the surgically treated patients. Long-term research of the capsula fibrosa is conducted with histological, immunofluorescent and biological experiment with implantation in test animals and histological research of the hepatic parenchyma for presence of protoscolekses in the capsule and beyond its limits. The Napalkov theory for this type of recurrence mechanism is not confirmed. The exact reasons for recurrence are revealed: not diagnosed during the operation smaller cysts (38.89% in the analyzed specimens); intraoperative dissemination of germ elements' incomplete sterilization of the echinococal cyst during the operation; recontamination with oncospheres. A new method for 100% sterilization of the fibrous cavity is introduced. Conclusions are made over the types of operations and the safest of them are recommend in connection with the research.
