Biliary obstruction resulting from strongyloides stercoralis infection. Report of a case

Abstract

Hepatobiliary manifestations of strongyloidiasis are rare. A case is described of biliary obstruction associated with the presence of Strongyloides stercoralis in the duodenal mucosa and 250 μm rhabditiform larvae in bile. Biliary obstruction resulted from papillary stenosis, which resolved after treatment with thiabendazole. It is proposed that papillary stenosis may be responsible for obstructive jaundice associated with Strongyloides stercoralis infection, and that strongyloidiasis should be added to the causes of papillary stenosis.
