Purulent cholangitis and hepatic abscess after choledochoduodenostomy diagnosed by ERCP

The authors report on a case of purulent cholangitis and hepatic abscess developing 5 years after choledochoduodenostomy, diagnosed by means of ERCP.

After the ERCP examination, the patient became free from complaints, and could be discharged.
