This is a case report of ascaris worm in the common bile duct in a 61 year old lady. Ultrasound diagnosis was initially made based on the presence of linear hyperreflective foci within the common bile duct. ERCP confirmed a single worm within the duct. Balloon extraction was then successfully carried out following papillotomy. This case illustrates the value of ultrasound in the definitive diagnosis of biliary ascariasis and the therapeutic role of ERCP.

We report two cases of rural Malay women in Perak, Malaysia, with extrahepatic cholangiocarcinoma and coexistent biliary ascariasis. In both cases, the narrowed bile duct may have resulted in inability of the migratory nematode to return to the gastrointestinal tract. It may be reasonable, also, to postulate that chronic biliary tract infestation by Ascaris lumbricoides may have contributed to the development of cholangiocarcinoma; a situation similar to that observed in liver fluke infestation.

This is a report of a 57-year-old Malay lady who presented with recurrent episodes of cholangitis and septicaemia. A dilated biliary tree caused by a stenosing periampullary tumour was found to contain adult round worms. A pancreatico-duodenectomy was performed following biliary decompression. Ascarid worms are a rare cause of cholangitis in malignant biliary obstruction.
