    This study investigated retained gastric antrum in dogs, finding that common diagnostic tests did not reliably indicate gastrin levels. Recurrent ulcers may stem from factors beyond elevated gastrin.

    Area of Science:

    • Gastroenterology
    • Surgical Pathology

    Background:

    • Retained gastric antrum can lead to recurrent ulceration.
    • The role of gastrin in this condition requires further elucidation.

    Purpose of the Study:

    • To evaluate diagnostic methods for retained gastric antrum.
    • To correlate diagnostic findings with histopathology in dogs.

    Main Methods:

    • Evaluation of six dogs with retained gastric antrum.
    • Assessment of secretin and calcium infusion effects on gastrin levels.
    • Utilizing 99mTc scanning for diagnostic purposes.

    Main Results:

    • Secretin and calcium infusions did not significantly alter circulating gastrin levels.
    • 99mTc scanning was consistently positive, irrespective of parietal cells.

  • Hypergastrinemia and gastrin cell hyperplasia were not consistently observed.

    • Conclusions:

    • Diagnostic methods did not consistently reflect gastrin levels in retained gastric antrum.
    • Factors other than gastrin may contribute to recurrent ulceration in this condition.
