    Heterotopic gastric mucosa in the rectum is rare and can mimic cancer. This study shows it can secrete acid, aiding surgical removal with pH-probe demarcation.

    Area of Science:

    • Gastroenterology
    • Surgical Pathology

    Background:

    • Heterotopic gastric mucosa in the rectum is an exceedingly rare condition.
    • It can present as rectal bleeding or a mass, necessitating differentiation from neoplastic lesions.

    Observation:

    • A case of rectal heterotopic gastric mucosa is presented and reviewed with 9 prior reports.
    • This is the first reported instance of measurable acid secretion from this ectopic mucosa in response to pentagastrin.

    Findings:

    • The heterotopic gastric mucosa demonstrated acid secretion upon pentagastrin stimulation.
    • A pH-probe, following pentagastrin administration, effectively demarcated the lesion.

    Implications:

    • Accurate demarcation using pH-probe technology facilitates complete surgical excision of rectal heterotopic gastric mucosa.
