Aim. To analyze the results of diagnosis and treatment of combined echinococcosis. Material and methods. The study included 51 children. 40 (78.4%) of them had combined lesion of liver and other organs, 29 — combined echinococcosis of liver and lungs. Echinococcosis of both lungs was observed in 14 children including lesion of liver in 6 cases. Combined echinococcosis of three organs was observed in 5 patients. Results and discussion. Combined echinococcosis in children was associated with uneven growth of parasitic cysts in various tissues. Small cysts were revealed in 15 (37.5%) out of 40 observations of combined lesion of liver and other organs. 7 patients underwent medical therapy for small cysts after previous surgery for medium and large cysts. Rapid growth of remained cysts occurred within 1—3 months between surgical stages. It may be often associated with complications related to remained cyst especially in case of both lungs echinococcosis. There were 6 (11.8%) postoperative complications in 51 patients with combined echinococcosis. Recurrence occurred in 2 (3.9%) children. Deaths were absent. Conclusion. Conservative therapy for small cysts provides 2-fold decrease of operations number and prevents recurrence of the disease. Reduced period between surgical stages up to 11±2 days prevents complications in case of both lungs echinococcosis.
