Chenotherapy for gallstone dissolution. I. Efficacy and safety.

J L Thistle, A F Hofmann, B J Ott

    JAMA
    |March 13, 1978
    PubMed
    Summary

    Higher doses of chenodeoxycholic acid effectively dissolve gallstones. Adequate dosage is crucial for successful medical therapy of asymptomatic, radiolucent gallstones, with recurrence observed in some patients.

    Area of Science:

    • Gastroenterology
    • Hepatology
    • Pharmacology

    Background:

    • Gallstones affect a significant portion of the population.
    • Current treatment options for gallstones have limitations.
    • Chenodeoxycholic acid (CDCA) has emerged as a potential medical therapy.

    Purpose of the Study:

    • To evaluate the clinical efficacy of chenodeoxycholic acid in dissolving gallstones.
    • To identify factors influencing the response rate to CDCA therapy.
    • To assess the safety and recurrence rates of CDCA treatment.

    Main Methods:

    • Retrospective analysis of patients treated with chenodeoxycholic acid.
    • Dosage stratification to assess dose-response relationship.
    • Evaluation of stone characteristics (size, type, location) and gallbladder visualization as determinants of response.

    Main Results:

    • Higher CDCA dosage (≥15 mg/kg/day) resulted in a significantly higher response rate (83%) compared to lower doses (38%).
    • Large solitary stones, poorly visualized gallbladders, and radiopaque stones showed lower response rates.
    • Common bile duct stones had a moderate response rate (50%).
    • Biochemical abnormalities (SGOT elevation) and side effects (diarrhea) were minimal.
    • Gallstone recurrence was observed in 3 out of 15 patients within 6-48 months post-treatment.

    Conclusions:

    • Chenodeoxycholic acid is a promising medical therapy for asymptomatic, radiolucent gallstones.
    • Adequate dosing is critical for achieving successful gallstone dissolution.
    • Patient and stone characteristics influence treatment outcomes, and recurrence is possible.
