This is a report of a case of acute cholangitis and cholecystitis secondary to fasciolosis in a 22 year old woman from Huaral (Lima, Peru) who had previously consumed emolientes (Emolientes are beverages made by steeping leaves of certain plants -watercress, alfalfa- or herbs in hot water). She had been ill for five days prior to admission with abdominal pain, vomiting, icterus, and anorexia. During the operation, foreign bodies were found and during the subsequent days of her hospitalization, adult forms of the trematode Fasciola hepatica were found to be obstructing the Kehr drain that had been placed intraoperatively. ERCP showed the parasites in the biliary tract. This is the second reported case of extraction of this parasite through this means. The epidemiology, radiologic findings, and diagnostic tests for infection by this parasite are discussed, with particular respect to Peru, one of the countries with the highest prevalence of infection by this parasite in the world.
