RESUMO
According to the world medical literature echinococcus is mostly located in the liver (60%). In the period 1978-1987 42 patients, 22 male and 20 female, were operated upon at the Titov Veles Medical Center. In 27 of these patients echinococcosis on right lobe was found. There were no patients operated of solitary cyst in left lobe. In 6 persons echinococcosis has relapsed and in 4 it was found in other organs. In 5 bi-lobular, patients the most common age group was 30-60 years. In addition to the classical methods computerized tomography (CT), scintigraphy and ultrasound were also used for making diagnosis. The appropriate method of operation was selected depending on the status, size and location of cysts as well as on the changes in surrounding organs and accompanying complications.
