EVALUATION OF THE EFFECTIVENESS OF MICROSCOPY OF SURGICAL MATERIAL PERFORMED BY CITO! IN PATIENTS WITH SUSPECTED ECHINOCOCCOSIS

Abstract

Currently, the relevance of echinococcosis is due to their wide prevalence in Russia. Cases of the disease are registered in more than 30 of the 88 administrative territories of the country. In establishing the final diagnosis of echinococcosis, the main importance is given to instrumental (ultrasound, CT, MRI) and serological methods (determination of specific antibodies based on ELISA). However, imaging methods in some cases do not allow to differentiate echinococcal cysts from other volumetric formations, and serological tests can give false negative results. Hydatidoses are characterized by a long course, and are often diagnosed late when complications develop. The surgical method is considered a radical method of treatment. Confirmation of the diagnosis is the results of pathomorphological examination of the surgical material. Of the 47 examined samples of operational material performed by cito! Protoscolexes of E. granulosus were found in 31 patients (65.7%). In two cases (4.3%), only single hooks of larvae of this parasite were found in the studied samples. In three patients (6.4%), the echinococcal nature of cysts was confirmed by delayed pathomorphological studies of the surgical material with the production of histological sections. In eleven patients (23.4%), the parasitic nature of the volume formations was excluded.
