Hepatobiliary and Pancreatic Duct Ascariasis: An Unusual Cause of Obstructive Jaundice and Severe Acute Cholangitis

“…Ascaris is caused by Ascaris lumbricoides a nematode roundworm, which is among the most common gastrointestinal parasitic infection worldwide. It infects 1.2 billion people worldwide causing about 60,000 deaths per year 1 , 2 The disease is most prevalent in tropical and subtropical developing countries 3 Though it is an intestinal parasite, the worm can migrate to extraintestinal organs like the biliary system with an occasional invasion of the biliary tract leading to a variety of complications including cholecystitis, obstructive jaundice, and cholangitis.
