[Various complications of primary echinococcosis].

Secondary echinococcosis occurs as a complication of a primary cyst. The importance of operative technique during the removal of the primary cyst is emphasized, because the intraoperative disemination occurs most frequently after a surgical performance. Secondary echinococcosis generates by asexual regressive metamorphosis of larval element intro larval forms. Two cases of secondary abdominal echinococcoosis will be described ensuing after removal of the primary liver cyst. One patient, who has been operated because of the pulmonary echinococcosis cyst before, was cured in our hospital having the secondary echinonoccosis of the lungs and pleural cavity.
