    Phenobarbital did not improve gallstone dissolution with chenodeoxycholic acid. Chenodeoxycholic acid alone was more effective for dissolving gallstones, with fewer side effects observed.

    Area of Science:

    • Hepatology
    • Gastroenterology
    • Biliary Medicine

    Background:

    • Gallstone dissolution therapy aims to reduce bile saturation.
    • Chenodeoxycholic acid (CDC) is a primary agent for gallstone dissolution.
    • The role of phenobarbital (PB) in conjunction with CDC is not fully elucidated.

    Purpose of the Study:

    • To compare the efficacy of chenodeoxycholic acid (CDC) alone versus CDC combined with phenobarbital (PB) for gallstone dissolution.
    • To analyze the impact of these treatments on biliary lipid composition and saturation index.
    • To evaluate the side effects and recurrence rates associated with these therapies.

    Main Methods:

    • Patients with radiolucent gallstones received either CDC alone or CDC with PB for 1.5 to 2 years.
    • Biliary lipids and gallstone dissolution were monitored.

  • Saturation index and side effects were assessed.

    • Main Results:

    • Gallstone dissolution occurred in 53% of patients on CDC alone, compared to 25% on CDC and PB.
    • No dissolution was observed in patients with calcified gallstones.
    • Patients with dissolution showed higher molar percentages of CDC and lower bile saturation indices.

    Conclusions:

    • Phenobarbital does not enhance CDC-induced bile desaturation or gallstone dissolution.
    • CDC monotherapy appears more effective for gallstone dissolution than combination therapy with PB.
    • Diarrhea was the primary side effect requiring dose reduction; gallstone recurrence was noted post-treatment.
