Is bile reflux at endoscopy a significant finding?

I A Eyre-Brook, A M Holroyd, A G Johnson

    Scandinavian Journal of Gastroenterology. Supplement

    Summary

    Postprandial duodenogastric reflux (DGR) is often present in dyspepsia patients. Scintigraphy showed DGR in patients with endoscopic bile reflux (EBR), but most cases remained within normal limits.

    Area of Science:

    • Gastroenterology
    • Nuclear Medicine
    • Diagnostic Imaging

    Background:

    • Postprandial dyspepsia is a common gastrointestinal complaint.
    • Endoscopic evidence of bile reflux (EBR) may be associated with dyspeptic symptoms.
    • The role of duodenogastric reflux (DGR) in dyspepsia requires further investigation.

    Purpose of the Study:

    • To assess postprandial duodenogastric reflux (DGR) in patients with dyspepsia and endoscopic bile reflux (EBR).
    • To compare DGR levels in patients with and without EBR against asymptomatic controls.

    Main Methods:

    • Scintigraphy was used to measure DGR after a liquid Lundh meal.
    • Iminodiacetic acid (IDA) was employed as the radiotracer.
    • DGR was quantified as the percentage of hepatic IDA appearing in the gastric region.

    Main Results:

    • Asymptomatic controls showed DGR from 0-5%.
    • Dyspeptic patients without EBR exhibited DGR from 0-6%.
    • Patients with EBR displayed a wide range of DGR (0-16%), with only 20% exceeding the normal range (0-5%).

    Conclusions:

    • While DGR can be elevated in patients with EBR, most cases fall within normal limits.
    • Scintigraphy is a valuable tool for quantifying DGR in dyspepsia.
    • Further research is needed to elucidate the precise relationship between DGR, EBR, and dyspeptic symptoms.
