Endoscopic management of a relapsing hepatic hydatid cyst with intrabiliary rupture: Life Cycle The adult Echinococcus granulosus 3 to 6 mm long resides in the small bowel of the definitive hosts, dogs or other canids.

Humans granulossus infected by ingesting eggsechinococus resulting release of oncospheres in the intestine and the development of cysts,in various organs. The effect of the hydatid cyst on the intermediate host depends on the size and location of the cyst. However, due to its relatively low prevalence in many Western countries, this infection is poorly characterized and its complex management can be difficult for clinicians unfamiliar with this condition.

When US and serology are inconclusive, a direct analysis of the material obtained by percutaneous aspiration is needed.

Despite the development of sensitive laboratory tests and the use of different antigen sources, serology remains complementary to imaging in the diagnosis of CE.

Maintenance of eradication is secured through the continuous surveillance monitoring of human, canine and livestock populations. Serologic testing for CE is hampered by many problems[ 41 – 4345 ]. Peritoneal seeding has never been reported, but it is difficult to assess the true rate because many reported series have a short follow-up time. False-positive reactions may occur in persons with other helminthic infections, cancer, and chronic immune disorders.
