Abnormal duodenal loop and pyloric regurgitation

P Thommesen

    Acta Radiologica: Diagnosis
    |July 1, 1977
    PubMed
    Summary

    Pyloric regurgitation is more common in patients with duodenal anomalies. This condition, often occurring when upright, can be managed by changing position or using metochlopramide.

    Area of Science:

    • Gastroenterology
    • Human Physiology

    Background:

    • Dyspepsia affects many patients without gastric ulcers.
    • Duodenal anomalies can influence upper gastrointestinal motility and symptoms.

    Purpose of the Study:

    • To investigate the association between duodenal anomalies and pyloric regurgitation in dyspeptic patients.
    • To explore methods for preventing or mitigating pyloric regurgitation.

    Main Methods:

    • Studied 48 patients with dyspepsia and no gastric ulcer.
    • Assessed pyloric regurgitation in relation to duodenal morphology (distal, combined, short loop, proximal anomalies vs. normal).
    • Evaluated the effect of body position and metochlopramide on regurgitation.

    Main Results:

    • Pyloric regurgitation was significantly more frequent in patients with distal/combined duodenal anomalies or a short duodenal loop compared to those with a normal duodenal loop.
    • No significant difference in regurgitation was observed between patients with proximal duodenal anomalies and the normal group.
    • Regurgitation in the erect position was preventable by assuming a supine position or administering intravenous metochlopramide.

    Conclusions:

    • Distal and combined duodenal anomalies, as well as short duodenal loops, are associated with increased pyloric regurgitation in dyspeptic patients.
    • Body positioning and metochlopramide administration are potential interventions for managing positional pyloric regurgitation.
