Hidden Nematode Causing Recurrent Pancreatitis: A Case Report.

Even though hepatobiliary ascariasis has been found to cause pancreatitis, it is rare in Qatar and other countries in the Middle East. In this report, we present a case of biliary duct ascariasis causing recurrent pancreatitis. A 46-year-old woman from the Philippines presented with recurrent clinical and biochemical features of acute pancreatitis and was found to have hepatobiliary ascariasis. She was successfully treated with endoscopic retrograde cholangiopancreatography (ERCP) and antihelminthic medication. Although hepatobiliary ascariasis as a cause of pancreatitis is rare, it should be considered in patients with recurrent pancreatitis without an obvious cause, especially in those from endemic areas or those who have visited endemic areas.
