    Summary

    A persistent antral response to meat extract after surgery suggests incomplete vagotomy. This finding aids in diagnosing surgical success for duodenal ulcer patients.

    Area of Science:

    • Gastroenterology
    • Surgical Research
    • Acid Secretion Studies

    Background:

    • Vagotomy is a surgical procedure to reduce stomach acid production.
    • Assessing the completeness of vagotomy is crucial for managing duodenal ulcers.
    • The role of the antrum's response to stimulation in indicating vagotomy success requires clarification.

    Purpose of the Study:

    • To determine if a persistent antral response to meat extract indicates incomplete vagotomy.
    • To correlate antral acid and gastrin responses with postoperative Hollander test results.

    Main Methods:

    • Preoperative and postoperative acid studies were performed on 29 duodenal ulcer patients.
    • Patients were categorized into antral and nonantral responders preoperatively.
    • Postoperative Hollander tests and responses to meat extract stimulation were analyzed.

    Main Results:

    • Two patients with early positive Hollander tests showed increased acid and gastrin response to meat extract.
    • One patient with a late positive Hollander test had no response to meat extract.
    • Two patients with stomal ulcers and negative Hollander tests exhibited increased acid and gastrin output after meat extract stimulation.

    Conclusions:

    • A significant antral acid and gastrin response to meat extract suggests incomplete vagotomy.
    • Meat extract stimulation can help identify incomplete vagotomies, even in the presence of stomal ulcers.
    • This response serves as a potential indicator for assessing surgical outcomes in vagotomy procedures.
