The treatment results of 199 children with lung echinococcosis was performed. 78 (39.2%) had complicated forms of the disease. The organ-preserving operations were predominately performed: traditional echinococcectomy in 177 (89%) and videothoracoscopic echinococcectomy in 15 (7.5%). Lobe resection was performed in 2 patients. 5 patients cured without surgery thank to bronchial cyst evacuation. The long-term follow-up data were obtained from 163 (82%) of patients. Reccurense of the hydatid disease was registered in 8 (4.9%) patients. The study demonstrated the importance of immediate surgery after the cyst rupture with pleural dissemination and early recurrence diagnostics, which allows conservative treatment.
