Malignant colon polyps--cure by colonoscopy or colectomy?

J P Christie

    The American Journal of Gastroenterology
    |July 1, 1984
    PubMed
    Summary

    Malignant pedunculated polyps can often be cured with colonoscopic removal if specific criteria are met. Sessile polyps generally require colectomy, but individual assessment is crucial for optimal treatment decisions.

    Polypectomy or colectomy? Management of 106 consecutively encountered colorectal polyps.

    The American surgeon·1988

    Area of Science:

    • Gastroenterology
    • Surgical Oncology
    • Endoscopic Procedures

    Background:

    • Malignant colon polyps present a therapeutic challenge, with traditional treatment often involving colectomy.
    • Distinguishing between sessile and pedunculated morphologies is critical for determining management strategies.

    Purpose of the Study:

    • To evaluate the efficacy of colonoscopic polypectomy versus colectomy for malignant polypoid lesions.
    • To establish criteria for curative colonoscopic removal of malignant pedunculated polyps.

    Main Methods:

    • Review of 83 consecutively encountered malignant polypoid lesions.
    • Analysis of outcomes based on polyp morphology (sessile vs. pedunculated) and treatment modality (colonoscopic polypectomy vs. colectomy).

    Main Results:

    • All 49 malignant pedunculated polyps were removed colonoscopically with no residual cancer in most cases.
    • Colectomy was performed for 34 malignant sessile lesions, with 21 removed colonoscopically initially.
    • Colonoscopic polypectomy was curative for pedunculated polyps meeting strict criteria (no stalk involvement, no invasion, well-differentiated, clear follow-up).

    Conclusions:

    • Colonoscopic polypectomy can be curative for select malignant pedunculated polyps, avoiding colectomy.
    • Colectomy remains the recommended treatment for most malignant sessile polyps.
    • Individual patient assessment, considering clinical history and histopathology, is essential for treatment decisions.
