Gastro-oesophageal function in duodenal ulcer patients
Scandinavian Journal of Gastroenterology
|January 1, 1980
Summary
Patients with duodenal ulcers (DU) exhibit impaired gastro-oesophageal sphincter function and reduced acid clearance, leading to increased acid reflux. Peristaltic activity in the oesophagus is also altered in these patients.
Area of Science:
- Gastroenterology
- Physiology
Background:
- Duodenal ulcer (DU) disease is a common gastrointestinal disorder.
- The gastro-oesophageal region's function in DU patients requires further elucidation.
Purpose of the Study:
- To investigate gastro-oesophageal function in patients with uncomplicated duodenal ulcers.
- To compare these findings with a control group of healthy volunteers.
Main Methods:
- Studied 39 patients with uncomplicated duodenal ulcers and a control group.
- Measured gastro-oesophageal sphincter pressure, acid-clearing ability, and reflux episodes.
- Assessed oesophageal peristaltic activity, including reversed peristalsis.
Main Results:
- DU patients showed lower gastro-oesophageal sphincter pressure and reduced acid-clearing ability.
- Increased acid gastro-oesophageal reflux and prolonged reflux episodes were observed in DU patients.
- Elevated reversed peristaltic activity was noted in DU patients.
Conclusions:
- Duodenal ulcer patients have compromised gastro-oesophageal sphincter function and impaired acid clearance, contributing to acid reflux.
- Altered oesophageal peristaltic activity is present in DU patients during reflux episodes.
