Bile acid-mediated postcholecystectomy diarrhea.

F L Arlow, A A Dekovich, R J Priest

    Archives of Internal Medicine
    |July 1, 1987
    PubMed
    Summary

    Post-cholecystectomy diarrhea is often caused by excess bile acids reaching the colon. This study found elevated fecal bile acids in most patients, which were successfully treated with cholestyramine resin.

    Area of Science:

    • Gastroenterology
    • Digestive System Disorders

    Background:

    • Diarrhea following cholecystectomy can be debilitating.
    • A proposed mechanism is "cholerheic enteropathy," where increased bile acids impact the large bowel.

    Purpose of the Study:

    • To investigate the cause of chronic diarrhea in patients post-cholecystectomy.
    • To identify the role of bile acid malabsorption in this condition.

    Main Methods:

    • Studied eight patients experiencing diarrhea after cholecystectomy.
    • Analyzed stool for abnormalities, focusing on bile acid levels and weight.

    Main Results:

    • Six out of eight patients showed elevated fecal bile acids.
    • Patients with bile acid malabsorption exhibited high daily stool weights (>200 g) and significantly increased fecal bile acids (3-10x normal).

    Conclusions:

    • Elevated bile acids in stool are a common cause of post-cholecystectomy diarrhea.
    • Cholestyramine resin effectively treated symptoms in patients with bile acid malabsorption.
