Gallstones after vagotomy

M Ihasz, C A Griffith

    American Journal of Surgery
    |January 1, 1981
    PubMed
    Summary
    This summary is machine-generated.

    Total vagotomy increases gallstone formation, particularly in patients with gallbladder hypotonia. Selective vagotomy, however, prevents these adverse effects, safeguarding gallbladder function.

    Area of Science:

    • Gastroenterology
    • Surgical Outcomes
    • Biliary System Physiology

    Background:

    • Vagotomy is a surgical procedure involving the vagus nerve, often performed with pyloroplasty for peptic ulcer disease.
    • The impact of different vagotomy types on gallbladder function and gallstone formation remains a critical area of investigation.

    Purpose of the Study:

    • To compare the long-term effects of selective vagotomy versus total vagotomy on gallbladder function and gallstone incidence.
    • To elucidate the relationship between gallbladder hypotonia and gallstone development following vagotomy.

    Main Methods:

    • Prospective study comparing selective vagotomy (n=53) and total vagotomy (n=91) with pyloroplasty.
    • Pre- and postoperative cholecystography used to assess gallbladder size, motility, and gallstone formation over 4-7 years.

    Main Results:

    • Selective vagotomy group showed no significant changes in gallbladder size or motility, with a low gallstone incidence (2/53).
    • Total vagotomy group exhibited a higher incidence of gallbladder dilation (46/91) and non-contractility (30/46), leading to increased gallstone formation (9/46).
    • Gallstone incidence in total vagotomy patients was strongly associated with significant gallbladder hypotonia.

    Conclusions:

    • Total vagotomy significantly increases the risk of gallstone formation, primarily in patients with pre-existing or induced gallbladder hypotonia.
    • Selective vagotomy appears to prevent the adverse sequelae on gallbladder function and reduces gallstone incidence compared to total vagotomy.
