Abstract
Hepatobiliary ascariasis is commonly reported from highly endemic regions like India, Bangladesh, Latin America, parts of Middle East and Africa. In humans, the usual habitat of Ascaris lumbricoides is the small intestine. When the worm load is high, going as high as more than 1000 worms, then the worms tend to migrate away from the usual site. Patients with hepatobiliary ascariasis may present with biliary colic due to obstruction caused by the worms in the gall bladder, common bile duct or as a result of obstructive symptoms caused by calcified worms or lithiasis, which is commonly found in patients with hepatobiliary ascariasis. Acute pancreatitis may also be caused by ascariasis. Management usually is conservative if it is still alive or can be extracted by endoscopic retrograde cholangio-pancreatography or surgery.
