Intestinal pseudo-obstruction in systemic amyloidosis.

D A Legge, E E Wollaeger, H C Carlson

    Summary

    Systemic amyloidosis can mimic mechanical intestinal obstruction. Early diagnosis through imaging and biopsy is crucial to avoid unnecessary surgery and ensure timely treatment for gastrointestinal amyloidosis.

    Area of Science:

    • Gastroenterology
    • Internal Medicine
    • Pathology

    Background:

    • Systemic amyloidosis is a rare condition characterized by the buildup of abnormal proteins in organs.
    • Gastrointestinal involvement is common in systemic amyloidosis but often presents insidiously.
    • Clinical manifestations can mimic other gastrointestinal disorders, leading to diagnostic challenges.

    Purpose of the Study:

    • To report on clinical manifestations of mechanical intestinal obstruction in systemic amyloidosis.
    • To review previously reported cases and highlight diagnostic considerations.
    • To emphasize the importance of considering systemic amyloidosis in patients with unexplained intestinal obstruction.

    Main Methods:

    • Case series reporting eight patients with systemic amyloidosis and intestinal obstruction.
    • Review of seven similar cases from existing medical literature.
    • Diagnostic procedures included plain films, barium enema, and mucosal biopsies.

    Main Results:

    • Eight new cases of intestinal obstruction due to systemic amyloidosis were identified.
    • Review confirmed the rarity and diagnostic difficulty of this presentation.
    • Plain films may show paralytic ileus, potentially masking mechanical obstruction.
    • Barium enema can help exclude distal obstructing lesions.
    • Rectal or small-intestinal biopsy safely confirms amyloidosis.

    Conclusions:

    • Systemic amyloidosis should be considered in patients presenting with mechanical intestinal obstruction, especially when imaging suggests paralytic ileus.
    • Prompt diagnosis via biopsy can prevent inappropriate surgical interventions.
    • Early recognition and diagnosis are key to managing gastrointestinal manifestations of systemic amyloidosis.
