title: Endoscopic removal of Ascaris lumbricoides from the biliary tract as emergency treatment for acute suppurative cholangitis.
abstract: Ascariasis is the most common intestinal helminthiasis worldwide. Heavily infected individuals are prone to develop bowel obstruction or perforation as well as biliary disease. Nevertheless, the presence of roundworms in the biliary tree outside endemic areas is very uncommon. The migration of these worms to the biliary system can cause biliary colic, pancreatitis, or even acute suppurative cholangitis with hepatic abscesses and septicemia. We report here on 2 infants with 14 and 15 months and a 9-year-old boy who suffered from massive biliary ascariasis and who presented with acute suppurative cholangitis. All cases were successfully treated by endoscopic retrograde cholangiopancreatography with worm extraction and adjuvant medical therapy. Physicians should be aware of ascariasis in patients with pancreatobiliary symptoms who have traveled to endemic areas or in immigrants from these areas.
