Endoscopic stenting for definitive treatment of irretrievable common bile duct calculi. A long-term follow-up study of 49 patients

Background/Aims: The value of endoprostheses for long-term management of bi le duct stones has not been formally established. A prospective evaluation of results and complications of the insertion of biliary endoprostheses was performed in patients with endoscopic irretrievable bile duct stones. Methodology: From January 1990 to September 1998, 49 patients (18 men and 3 1 women; average age 75.5 years), underwent endoscopic biliary stenting for endoscopically irretrievable bile duct stones. Results: Successful biliary drainage was achieved in all patients. Early co mplications occurred in 12.2% of cases. Over the long-term follow-up (media n follow = 39 months) late complications occurred in 40.8% of cases, with 3 cases of biliary-related death. Conclusions: For immediate bile duct drainage, endoprostheses proved a safe and effective alternative for treatment of patients with endoscopically ir retrievable bile duct stones. Because of the risk of subsequent complicatio ns, its use as a definitive treatment should be confirmed to highly selecte d cases.
