Diagnosis and treatment of a case of hepatic mixed echinococcosis infection combined with distant organ metastasis.

Hydatidosis is a zoonotic parasitic disease caused by Echinococcus, which is highly prevalent in pastoral areas. In China, this disease is mainly caused by Echinococcus granulosus and Echinococcus multilocularis. Cystic echinococcosis, which is one of the most common types of echinococcosis, is described as swelling and growth of cystic lesions. Alveolar echinococcosis, which is less common, is invasive. Cases of mixed echinococcosis infection accompanied by extrahepatic organ metastasis are extremely rare. Treatment of these cases is complicated and the prognosis is extremely poor. We report a case of hepatic echinococcosis in a 40-year-old Tibetan man who was treated with the hepatic right tricuspidectomy + left hepatic duct jejunostomy (Roux-en-Y) surgical procedure. This procedure provides a reference for treatment of similar cases of echinococcosis. For patients with multiorgan metastasis, chemotherapy is the first choice. This should be followed by possible surgical treatment for life-threatening lesions of alveolar echinococcosis and subsequent chemotherapy. Individualized treatment accompanied by multidisciplinary treatment and damage control surgery could optimally benefit patients with advanced hepatic echinococcosis.
