    Summary

    Chenic acid treatment aids gall-stone dissolution. Dissolution rate depends on gall-stone size and bile unsaturation during treatment, impacting treatment duration.

    Area of Science:

    • Gastroenterology
    • Hepatology
    • Pharmacology

    Background:

    • Gallstones are common and can cause significant morbidity.
    • Chenic acid has been used to dissolve gallstones.
    • Factors influencing dissolution rate require further elucidation.

    Purpose of the Study:

    • To investigate the factors affecting gallstone dissolution rate during chenic acid therapy.
    • To determine the relationship between initial gallstone size, bile cholesterol saturation, and dissolution efficacy.

    Main Methods:

    • 52 patients with radiolucent gallstones received chenic acid (15 mg/kg/day).
    • Gallstone area reduction was measured over six months.
    • Cholesterol saturation index (CSI) of fasting gallbladder bile was assessed during treatment.

    Main Results:

    • Gallstone dissolution rate was inversely related to initial gallstone diameter (r = -0.53).
    • Dissolution rate was also inversely related to bile CSI during treatment (r = -0.61).
    • Treatment duration for complete dissolution correlated positively with initial gallstone diameter (r = 0.47).

    Conclusions:

    • Gallstone dissolution rate is influenced by both gallstone size and bile unsaturation.
    • Achieving adequate bile unsaturation is crucial for effective chenic acid therapy.
    • Chenic acid treatment efficacy is modulated by patient-specific factors and treatment response.
