Stenting for choledocholithiasis: temporizing or therapeutic?

D G Maxton, D E Tweedle, D F Martin

    The American Journal of Gastroenterology
    |March 1, 1996

    Summary

    Biliary endoprostheses safely manage retained common bile duct stones after failed clearance, improving patient outcomes. This approach prevents urgent surgery and allows for staged treatment in elderly, ill patients.

    Area of Science:

    • Gastroenterology and Hepatology
    • Interventional Endoscopy
    • Biliary Tract Interventions

    Background:

    • Choledocholithiasis (common bile duct stones) is a frequent clinical problem.
    • Endoscopic retrograde cholangiopancreatography (ERCP) is the primary treatment for bile duct stone clearance.
    • Failed stone clearance during ERCP necessitates alternative management strategies, particularly in elderly and comorbid patients.

    Purpose of the Study:

    • To evaluate the safety and efficacy of biliary endoprostheses (stents) for managing retained common bile duct stones after failed ERCP stone clearance.
    • To assess the need for urgent surgical intervention and patient outcomes in this cohort.

    Main Methods:

    • Retrospective analysis of 85 patients with retained common bile duct stones after initial ERCP.

    Related Experiment Videos

  • Placement of 7-French double pigtail stents in patients with persistent stones.
  • Subsequent ERCPs at 2-3 month intervals, with options for mechanical lithotripsy, ESWL, or dissolution therapy; long-term stenting for frail patients.

    • Main Results:

    • 84 of 85 patients experienced resolution of acute illness; significant improvements in bilirubin and alkaline phosphatase levels were observed.
    • 50 of 79 patients achieved successful stone clearance, with most requiring multiple ERCP sessions (68% needed two, 20% three).
    • 26 patients maintained long-term biliary drainage with stents in situ (>12 months); 3 patients were referred for surgery.

    Conclusions:

    • Placement of a single 7-French biliary stent after failed common bile duct stone clearance is safe and effective.
    • Biliary stenting provides adequate drainage, prevents urgent surgical intervention, and facilitates staged management of retained stones.
    • This approach is particularly beneficial for elderly and critically ill patients, allowing transfer to specialized centers.
