Giant pseudopolypoidal retrograde obstruction in ulcerative colitis.

A Solomon, J Stadler, L Goland

    The American Journal of Gastroenterology
    |April 1, 1983
    PubMed
    Summary

    A giant pseudopolyp blocked colon examination. Oral Gastrografin, a water-soluble contrast medium, successfully visualized the proximal colon, proving useful in special cases.

    Area of Science:

    • Gastroenterology
    • Diagnostic Imaging
    • Colorectal Surgery

    Background:

    • Standard colon examination methods like sigmoidoscopy and barium enema can be limited by colonic obstructions.
    • Giant pseudopolyps pose a significant challenge to visualizing the entire colon.
    • Accurate visualization of the proximal colon is crucial for diagnosis and treatment planning.

    Observation:

    • A patient presented with a partially obstructing giant pseudopolyp in the left colon.
    • This obstruction prevented standard endoscopic and radiographic examination of the proximal colon.
    • Oral Gastrografin (a water-soluble contrast medium) was administered.

    Findings:

    • The water-soluble contrast medium successfully opacified the colon.
    • Gastrografin provided visualization of the previously inaccessible proximal colon.

  • This technique overcame the diagnostic limitations imposed by the colonic obstruction.

    • Implications:

    • Water-soluble contrast media can be a valuable tool for colonic investigation in specific clinical scenarios.
    • This approach offers an alternative when conventional methods are contraindicated or ineffective.
    • It highlights the adaptability of contrast media for challenging diagnostic situations in gastroenterology.
