Decrease in gastric secretion during the first three months after proximal gastric vagotomy in duodenal ulcer

M Roland, A Berstad, I Liavåg

    Scandinavian Journal of Gastroenterology
    |January 1, 1975
    PubMed
    Summary

    Proximal gastric vagotomy significantly reduces pentagastrin-stimulated gastric acid output in duodenal ulcer patients. Gastric juice volume and pepsin output are also affected post-surgery.

    Area of Science:

    • Gastroenterology
    • Surgical Research
    • Pharmacology

    Background:

    • Duodenal ulcers are common gastrointestinal disorders.
    • Proximal gastric vagotomy is a surgical procedure to reduce gastric acid secretion.
    • Understanding the long-term effects of vagotomy on gastric function is crucial.

    Purpose of the Study:

    • To evaluate the effect of proximal gastric vagotomy on gastric secretion stimulated by pentagastrin.
    • To assess the impact of carbacholine on gastric secretion post-vagotomy.
    • To compare gastric secretion parameters at different time points after surgery.

    Main Methods:

    • 16 duodenal ulcer patients underwent proximal gastric vagotomy.
    • Gastric secretion was stimulated using intravenous pentagastrin infusion before and after surgery (10 and 90 days).

    Related Experiment Videos

  • Carbacholine was administered postoperatively in combination with pentagastrin.

    • Main Results:

    • Pentagastrin-stimulated acid output decreased by 48% (10 days) and 64% (90 days) post-vagotomy.
    • Gastric juice volume and acid output were higher at 10 days than 90 days post-surgery.
    • Carbacholine did not significantly affect acid output but increased gastric juice volume at 10 days.

    Conclusions:

    • Proximal gastric vagotomy effectively reduces pentagastrin-stimulated gastric acid secretion.
    • Gastric function recovery occurs between 10 and 90 days post-vagotomy.
    • Carbacholine's effect on gastric secretion is time-dependent after vagotomy.
