[Francke's operation--a resolution for deep small echinococcal cysts of the liver].

The operation of Francke in hydatid disease treatment is described--puncture, aspiration, sterilization--with emphasis laid on the technical details. The indications for its practical implementation are specified--small echinococcus cysts, deeply located within the parenchyma of the organ, or diffuse abdominal echinococcosis. In diagnosing such cysts intraoperative ultrasonography is considered as absolutely necessary and mandatory. The operation is practicable in handling first-stage cysts according to Volynkin, containing thin echinococcus liquid only, whereas in the presence of daughter vesicles it is not indicated. Postoperatively, dispensary outpatient observation and chemotherapy of the hydatid disease are recommended with a view to promote radical cure.
