Therapeutic Endoscopic Retrograde Cholangiopancreatography for the Treatment of Fasciola hepatica Presenting as Biliary Obstruction

Human infection with the Fasciola hepatica liver fluke is a rare cause of biliary obstruction, especially within the United States. Humans can become accidental hosts of this parasite by ingesting contaminated drinking water or plants. Symptoms during the acute phase include fever, right upper quadrant pain, eosinophilia, and hepatomegaly. During the chronic stage of infection, the parasite may remain asymptomatic for many years. This article presents a case of biliary obstruction due to Fasciola hepatica that was diagnosed and treated successfully with endoscopic retrograde cholangiopancreatography.
