Biliary ascariasis.

Abstract

Biliary ascariasis, rarely noted in the western literature, is a common condition in other climates. An increase in infestation may occur with travel to these countries. With the changes in biliary function which follow common duct exploration, invasion can occur in the affected individual. Treatment involves antispasmodics, antihelminthetics, and prevention of superinfection. Surgical intervention is reserved for specific indications of failure of medical therapy.
