[Hydatid cyst of the lung (author's transl)].

The authors, in an international collaborative study, report on 257 cases of operated hydatid cysts. The delicate choice between resection and conservative treatment depends on a protocole and/or on experience: in the large series published in the last 10 years the rate of resections has varied between 43 and less than 20 per cent. Cure of the pulmonary hydatid cyst, be it live or ruptured, is presently a well systemized, efficient and safe operation. The authors present their data that correlate well the sparse literature related to the subject in the last decade.
