Duodenogastric reflux after gastric surgery
Scandinavian Journal of Gastroenterology
|September 1, 1983
Summary
Patients experiencing post-gastric surgery symptoms like heartburn have higher bile reflux. However, gastric emptying and gastritis severity were similar in symptomatic and asymptomatic individuals, suggesting bile reflux is key to symptoms.
Area of Science:
- Gastroenterology
- Surgical Outcomes
- Digestive Physiology
Background:
- Gastric surgery can lead to complications such as heartburn, bile vomiting, and postprandial pain.
- The role of bile reflux, gastric emptying, and mucosal changes in these post-gastric surgery symptoms requires further elucidation.
Purpose of the Study:
- To compare bile reflux, gastric emptying, and gastric mucosal changes in patients with and without symptoms after gastric surgery.
- To investigate the correlation between these factors and symptom development.
Main Methods:
- Bile reflux was quantified using an isotope-derivative method.
- Gastric emptying of a liquid meal was assessed via a dye dilution technique.
- Gastric mucosal morphology was evaluated through endoscopic biopsies.
Main Results:
- Patients with post-gastric surgery symptoms exhibited significantly higher levels of bile reflux compared to asymptomatic controls.
- Gastric emptying rates for liquid meals were comparable between symptomatic and asymptomatic groups.
- Gastritis severity was similar in both groups and did not correlate with the degree of bile reflux.
Conclusions:
- Elevated bile reflux is a significant factor associated with symptoms following gastric surgery.
- Gastric emptying rate and gastritis severity do not appear to be directly related to the development of these symptoms.
