[The insulin test].

G Feifel, S Wagner, R Halbritter

    Zeitschrift Fur Gastroenterologie
    |August 1, 1979

    Summary
    This summary is machine-generated.

    The insulin test after vagotomy lacks correlation with ulcer recurrence and poses a hypoglycemia risk. Basal acid output, pentagastrin secretion, and endoscopy are recommended for evaluating outcomes.

    Area of Science:

    • Gastroenterology
    • Surgical Outcomes
    • Diagnostic Testing

    Background:

    • The insulin test, introduced by Hollander 30 years ago, has been used to assess the effectiveness of vagotomy.
    • Its clinical utility and interpretation following vagotomy have been a subject of ongoing discussion within the medical community.

    Purpose of the Study:

    • To evaluate the diagnostic value and reliability of the insulin test in predicting ulcer recurrence after vagotomy.
    • To identify more dependable methods for assessing outcomes post-vagotomy.

    Main Methods:

    • Review of historical data and clinical practice regarding the insulin test post-vagotomy.
    • Analysis of the correlation between insulin test results and ulcer recurrence rates.
    • Assessment of the risks associated with the insulin test, specifically hypoglycemia.

    Related Experiment Videos

  • Comparison with alternative methods like basal acid output, pentagastrin-stimulated acid secretion, and endoscopy.

    • Main Results:

    • No significant correlation was found between individual insulin test results and the incidence of ulcer recurrence.
    • The insulin test carries a substantial risk of inducing hypoglycemia, limiting its suitability for routine diagnostic use.
    • Alternative methods demonstrate greater reliability in evaluating post-vagotomy outcomes.

    Conclusions:

    • The insulin test is not a reliable predictor of ulcer recurrence following vagotomy.
    • Due to the high risk of hypoglycemia, the insulin test should not be relied upon for diagnostic purposes.
    • Basal acid output, pentagastrin-stimulated acid secretion, and endoscopy are recommended as more accurate and safer methods for evaluating outcomes after vagotomy.
