Abstract
We report a case of ascariasis invading into the bile duct. The removal of the worm was done by a basket catheter. We also reviewed some additional literatures.
On March 28, 1984, a 33-year-old woman was admitted to our hospital because of epigastralgia and back pain. She underwent cholecystectomy due to cholelithiasis when she was 21 years old. She used to wash vegetables by salt.
Laboratory examinations at the time of her hospitalization revealed eosinophillia and increasing urinary amylase.
Endoscopic retrograde cholangio-pancreatography (ERCP) demonstrated the Ascaris reaching right hepatic bile duct from the end of common bile duct.
Though the ascarid migrated entirely into the bile tract, we tried endoscopic therapy to make use of basket catheter and succeeded to remove a male ascarid, a length of 16cm.
At the present time maintaining high level of sanitary conditions, we seldom observe a case of ascariasis invasion of the bile duct. However, we should bear in mind of occurrence of such a rare case. Furthermore, as the method of endoscopic therapy is very useful, it is suggested that the above method be tried with first priority.
