    Cholesterol gallstones form in three stages, with bile saturation being the first. Medical dissolution therapies show promise for gallstone removal, but long-term safety and recurrence prevention require further research.

    Area of Science:

    • Gastroenterology
    • Hepatology
    • Biliary tract disease

    Background:

    • Cholesterol gallstone formation is a multi-stage process.
    • The initial stage involves bile saturation with cholesterol, leading to crystal formation.
    • Nucleation and growth stages are less understood.

    Purpose of the Study:

    • To review current understanding of cholesterol gallstone formation.
    • To evaluate medical therapies for gallstone dissolution.
    • To identify areas for future research in gallstone management.

    Main Methods:

    • Review of existing literature on gallstone formation and dissolution therapies.
    • Analysis of the efficacy and safety of chenodeoxycholic acid (CDCA) and ursodeoxycholic acid (UDCA).
    • Discussion of treatment modalities for retained or reformed bile duct stones.

    Main Results:

    • Chenodeoxycholic acid (CDCA) dissolves 60% of radiolucent gallstones, but long-term safety is unproven.
    • Ursodeoxycholic acid (UDCA) is a promising agent, but requires more study.
    • Prevention of gallstone recurrence post-dissolution is a significant unresolved issue.

    Conclusions:

    • Medical dissolution offers a potential alternative to cholecystectomy for radiolucent gallstones.
    • Further controlled trials are needed to establish optimal treatment indications for various gallstone conditions.
    • More research is necessary for UDCA, other agents, and dietary interventions.
