Hepatobiliary fascioliasis: clinical and radiologic features and endoscopic management.

Fasciola hepatica is a zoonotic liver fluke that can cause disease in humans. Fascioliasis is an uncommon disease. We retrospectively analyzed 9 cases of fascioliasis and reviewed the relevant literature. A high index of suspicion and specific ultrasonographic findings are very helpful in the diagnosis of the disease. However, serological studies and endoscopic retrograde cholangiopancreatography confirm the diagnosis. The disease has 2 stages: hepatic stage and biliary stage. While several drugs are used during the hepatic stage, endoscopic retrograde cholangiopancreatography is particularly effective in the biliary stage.
