Uncomplicated Hydatid Cysts of the Liver: Clinical Presentation, Diagnosis and Treatment

Kazim Duman, Mustafa Girgin,  Salih Hamcan

Hydatid cyst of the liver is zoonosis caused by the larval stages of taeniid cestodes belonging to the genus Echinococcus and is still endemic in the South European regions, Asia, South America, North Africa, Australia, New Zealand and several Asian and European countries. The diagnosis of non complicated hydatid cyst of the liver depends on clinical suspicion. They appear in two ways as general (systemic) symptoms, and local symptoms based on the site and organ on which larva settles. While cysts sometimes recover spontaneously, more severe clinical presentations are observed in immunosuppressive individuals. Ultrasonography is the gold standard diagnostic tool and E. Granulosus antigen 5 (Ag5) and antigen B (Ag B) obtained from cyst fluid are used as a serologic diagnostic method in combination with the imaging method. The current treatment of hydatid cyst of the liver varies from surgical intervention to minimally invasive treatments (percutaneous drainage) or medical therapies. Surgery is still the best treatment tool. Percutaneous drainage and treatment of the cyst is a good option to surgery in selected cases. Multiple, superficial single cysts are the most suitable ones for surgical treatment. Also for complicated infected cysts pressing biliary tree and vital organs, surgery should be the first choice of treatment coming to mind. We believe that the laparoscopic approach should be safe to uncomplicated cysts. The purpose of our article is to provide a current review of clinical, diagnostic, and therapeutic features of hydrated cyst diseases.
