Human alveolar echinococcosis (AE) is a highly pathogenic zoonotic parasitic disease caused by Echinococcus multilocularis. An ultrasound study in southern Kyrgyzstan during 2012 revealed a prevalence of 4.2% probable or confirmed AE and an additional 2.2% possible AE, representing an emerging situation. The risk for probable or confirmed AE was significantly higher in dog owners.

Aim. To improve the results of diagnosis and surgical treatment of liver alveococcosis.Material and methods. There were 415 patients with liver alveococcosis for the period 2009–2018. Liver resection was performed in 364 patients. Metastases in the brain were detected in 7 patients, lungs – in 3 cases, soft tissues involvement – in another 3 ones. Hepatic-bronchial fistula occurred in 2 cases. Mean age of patients was 41 ± 2.3 years. There were 128 (30.8%) men and 287 (69.2%) women.Results. Advanced liver resection was performed in 187 patients, atypical resection – in 177 cases. R0-resection was carried out in 62.4% of cases, R1–2 procedures – in 37.6%, diagnostic laparotomy – in 4.4%. Four patients died in early postoperative period.Conclusion. The final decision about resectability may be made after intraoperative assessment, intraoperative ultrasound, Doppler sonography and liver mobilization. Liver resection for advanced alveococcosis is extensive, needs for resection and replacement of great vessels, as well as bile ducts repair. Radical treatment is R0-resection if distant metastases are absent. Redo surgery is advisable for liver alveococcosis.

Surgery has remained the mainstay for the management of hydatid cysts. The success of any operation depends to a great extension how well the optimal surgical approach is chosen and which method of residual cyst sanitation. The purpose of the study was to analyze of complications after combined cyst, brain and abdominal, surgery. The complications associate with depth, size and relation to adjacent organs.
