RESUMEN
The combined hydatid disease was surgically treated in 101 patients. Among them three groups were distinguished: hydatid disease of the right lung and liver (n=51); bilateral lung and liver affection (n=33); hydatid disease of the left lung and liver (n=17). The method of choice in treatment of the left lung and liver diaphragmatic surface hydatid disease is the one-stage closed echinococcectomy by Delbe. Two- or three-stage operation is indicated in cases of bilateral echinococcosis. The surgical excision should be started from the mostly affected organ or from the site were complications are mostly expected. Patients with the combined hydatid disease of the left lung and liver are to experience the two-stage echinococcectomy. Operations should be performed in the range from 2 to 4 months. The overall lethality of the analyzed cohort was 10,2%.
