title: Biliary ascariasis: percutaneous transhepatic management.
abstract: In a 60-year-old woman who underwent cholecystectomy and T-tube drainage for biliary ascariasis, postoperative bilirubin levels continued to increase. T-tube cholangiography revealed multiple filling defects in the bile ducts, which suggested roundworm reinfestation. Because the patient could not tolerate endoscopy, a percutaneous transhepatic approach with balloon dilatation of the ampulla of Vater and subsequent advancement of roundworms into the duodenum with an embolectomy balloon was used. The procedure was successful, with no major complications. The use of a percutaneous transhepatic treatment to advancement of roundworms into the duodenum is a feasible alternative to surgery when endoscopic extraction fails.
