[Prevention of recurrent parasitic infections after surgical treatment of echinococcosis].

The results of surgical treatment of 741 patients with hydatid disease of the lungs, liver, and other abdominal organs were studied. Recurrences were found in different periods after the operation in 147 (19.8%) patients: solitary cysts in 34, multiple cysts in 90, and a combined affection in 23 patients. The recurrent cysts were revealed in a previously operated on hepatic lobe in 69, in the other lobe in 42, and in the other abdominal organs in 37 patients in 29 of which the cysts were located on the serosa of the abdominal organs. The recurrences were caused by a nonradical character of the first operation and dissemination of the embryonic elements with their subsequent implantation growth. On the basis of this, the author draws a parallel between the recurrence of malignant new growths and echinococcosis (alveococcosis) and formulates the general principles of aparasitism and antiparasitism of surgical interventions and similar principles of ablastemics and antiblastemics in oncology.
