Fasciola hepatica is a trematode which is found worldwide. The diagnosis is
usually delayed because the disease is relatively rare and the parasite or
its eggs must be shown in bile samples for verification. We report three c
ases in which the diagnosis of fascioliasis was established by simple US-gu
ided aspiration of the gallbladder. This new diagnostic method less invasiv
e, safe, and easy compared with the conventional endoscopic methods.
