Does gastric entubation cause entero-gastric reflux?
Scandinavian Journal of Gastroenterology. Supplement
|January 1, 1984
Summary
Naso-gastric intubation does not significantly affect bile reflux in patients with duodenal ulcers. Bile reflux detection in gastric ulcer patients is valid using naso-gastric aspiration, confirming its utility in duodenogastric reflux studies.
Area of Science:
- Gastroenterology
- Nuclear Medicine
- Medical Imaging
Background:
- Bile reflux is a concern in patients with duodenal and gastric ulceration.
- The impact of naso-gastric intubation on bile reflux requires investigation.
Purpose of the Study:
- To evaluate the effect of naso-gastric intubation on bile reflux in patients with duodenal ulceration.
- To assess the validity of naso-gastric aspiration for investigating bile reflux in gastric ulcer patients.
Main Methods:
- Utilized 99mTc diethyl HIDA (hepatobiliary iminodiacetic acid) scintigraphy.
- Studied 14 patients with duodenal ulceration and 19 patients with gastric ulceration.
- Employed gamma camera imaging and naso-gastric intubation with aspiration techniques.
Main Results:
- No significant change in stomach activity was observed after naso-gastric intubation in duodenal ulcer patients (Mann-Whitney U = 0.18).
- The incidence of bile reflux in gastric ulcer patients was consistent between gamma camera imaging and naso-gastric aspiration methods.
Conclusions:
- Naso-gastric intubation does not significantly alter bile reflux in patients with duodenal ulceration.
- Naso-gastric aspiration of gastric contents is a valid method for investigating duodenogastric reflux in patient groups.
