[Endoscopic removal by ERCP of Fasciola hepatica alive: two case reports and review of the literature].

We report two cases of biliary fascioliasis in patients from the highlands of Peru; with several months of symptoms characterized for biliary-type pain, dark urine and jaundice in one case. Both of them referred to the department of Gastroenterology of the Hospital Nacional Guillermo Almenara Irigoyen for suspicious of choledocolithiasis. Laboratory tests were performed which showed variable high levels of functional liver tests (cholestasis) and marked eosinophilia in one case. Magnetic resonance cholangiography (CRMN) was performed and then informed as an apparent image of biliary stone in choledocus in both cases. Endoscopic retrograde cholangiopancreatography (ERCP) was performed and after sphincterotomy, one flattened, lanceolate parasite, with active mobility morphologically compatible with Fasciola hepatica was extracted. After the ERCP antiparasitic treatment was given with triclabendazole. Clinical outcome was favourable.
