The purpose of this Work was to analyse results of serologie examinations and complaints reported by patients who were operated on echinococcal liver cysts. The analysis was conducted on patients who were qualified to surgical removal of echionococcal liver cysts. Persons who were analysed answered the questionaires and 11 of them send sera for serologie examination. The questionaires consisted of questions about time since operation, complaints before and after operation abdomen pains, distensions, vomits, exanthema, weakness, headaches). Results showed that patient were from 1 to 6 years after operation. Among 11 who send sera 18% results were negative (2 and 6 years after operation) and 82% was positive. Analysis of 15 questionnaires showed that majority of patients still had the complaints that were present before operation.
Liver cysts taken from 9 patients, operated on in the Medical Academy Clinic in 2000, have been examined. Cyst layers, their thickness and content have been analysed. We have searched for the cestoid scolexes and rostellar hooks. In 6 patients Echinococcus granulosus larvae have been found. In 4 cases there have been protoscolexes discovered, however with some signs of degeneration of the larva. In one case dead larva has been diagnosed on the basis of the presence of single hooks and in one patient one larva alive with unchanged structures has been revealed. Profound parasitological examination is a good supplement to the examination of the histopathological slides, especially in the case of degenerating larvae, when the tissues of the parasite lose their contact with the connective tissue layer of the host. Separated layer fragments, as well as protoscolexes and rostellar hooks need not be exposed to histological cutting.
