Abstract

A 77-year-old woman was admitted for vomiting and abdominal colic pain. Laboratory studies revealed elevated eosinocyte, AST, ALT, ALP, andγ-GTP. Abdominal ultrasonographic examination (US) showed a moving echogenic strip through the common bile duct to gallbladder. The worm getting into the papilla Vater was confirmed by endoscopic retrograde cholangiography. Although we tried to remove a worm using basket forceps after endoscopic papillary balloon dilatation, it was unsuccessful. Pyrantel pamoate was administered through ENBD tube placed in the common bile duct. On the next day, the dead worm in the gallbladder was observed by US. MR cholangiopancreatography also revealed a liner filling detect indicating the body of worm in the gallbladder, Oral administration of ursodeoxycholic acid (UDCA) was started, and debris finally disappeared about 6 months later. UDCA treatment is successful in protecting gallstone formation caused by Ascaris in the gallbladder.
