Acid secreting gastric heterotopia in the duodenum
Acta Chirurgica Scandinavica
|January 1, 1982
Summary
Heterotopic gastric mucosa in the duodenum caused acid hyposecretion and duodenitis. Surgical removal resolved symptoms and normalized acid secretion.
Area of Science:
- Gastroenterology
- Digestive Physiology
- Surgical Pathology
Background:
- Heterotopic gastric mucosa (HGM) is rare, with potential implications for gastrointestinal function.
- Understanding the secretory capacity of HGM is crucial for diagnosing related conditions.
Observation:
- A female patient presented with duodenitis and acid hyposecretion.
- Histological examination revealed isolated fundic glands in the duodenum.
- These glands demonstrated 14C-aminopyrine uptake, indicating acid secretion capacity.
Findings:
- Ectopic acid secretion from duodenal HGM suppressed gastric acid output.
- This ectopic secretion was implicated as a cause of duodenitis and clinical symptoms.
- Surgical excision of HGM led to symptomatic relief and normalized gastric acid secretion.
Implications:
- HGM can significantly impact gastric acid homeostasis and cause upper gastrointestinal pathology.
- Local excision of HGM is an effective treatment for associated symptoms and dysfunction.
- This case highlights the importance of considering HGM in unexplained duodenitis and acid secretion abnormalities.
