Abstract

Ascaris lumbricoides is the commonest intestinal parasite. The parasites are the most numerous intestinal parasites in less-developed countries and in areas with poor sanitation. However, it's prevalence is very low in Korea recently. A. lumbricoides produces no symptoms in most patients but sometimes it may give rise to intestinal obstruction or pancreatobiliary disease. Highly motile mature worms may enter the ampulla of Vater and migrate into the bile or pancreatic ducts and can cause cholangitis, biliary stone, cholecystitis, pancreatitis and liver abscess. The cases of biliary ascariasis are rare in Korea. We report a 59-year-old female, who presented with intermittent epigastic pain, diagnosed as biliary ascariasis associated with common bile duct stone after endoscopic retrograde cholangiopancreatography (ERCP). The common bile duct (CBD) stone was removed by sphincterotomy and lithotripsy, and then we directly removed ascaris with a basket without any complication.
