[Clinico-morphological basis of selection of the methods of treatment of echinococcosis of the abdominal organs and retro- peritoneal space].

The work is based on the analysis of surgical treatment of 2,985 patients with hydatid diseases of the organs of the abdominal cavity and retroperitoneal space. The character of the operative intervention is determined by the period of hydatid vital activity, its size, and the features of its localization within the organ. The authors identified the following periods of hydatid vital activity: living parasite, dead parasite; complicated echinococcosis. Organ preserving operations are indicated in subcortical localization of the hydatid in the liver, in one of the poles of the spleen and in the kidney when the fibrous capsule is well preserved. Splenectomy or nephrectomy must be carried out in large and giant hydatids of the spleen and kidney localized in the organ or in its hilus and in irreversible changes in the organ. Open echinococcectomy is indicated in suppuration of large hydatids in the subdiaphragmatic space in occasional cases.
