Colonscopic excision of sessile polyps

J P Christie

    The American Journal of Gastroenterology
    |July 1, 1976
    PubMed
    Summary

    Colonoscopic removal is now feasible for most benign sessile colon polyps, significantly reducing the need for abdominal surgery (laparotomy). This minimally invasive technique is effective for polyps up to 6 cm, reserving laparotomy for larger or invasive cancerous lesions.

    Area of Science:

    • Gastroenterology
    • Colorectal Surgery
    • Endoscopy

    Background:

    • Sessile colon polyps traditionally required laparotomy for removal.
    • Colonoscopic polypectomy has advanced, offering a less invasive alternative.

    Purpose of the Study:

    • To evaluate the efficacy and safety of colonoscopic excision for sessile colon polyps.
    • To determine the rate of successful colonoscopic removal versus laparotomy.

    Main Methods:

    • Review of 250 colonoscopy procedures identifying 87 sessile polyps.
    • Analysis of polyp size, malignancy, and method of removal (colonoscopic vs. laparotomy).
    • Assessment of techniques like piecemeal excision and radiowave electrocautery.

    Main Results:

    • Colonoscopic excision was successful for 79% of sessile colon polyps (68 of 87 lesions).
    • Malignancy was found in 3 of 68 endoscopically removed polyps and 6 of 16 surgically removed lesions.
    • Laparotomy was necessary for 16 lesions unsuitable for endoscopic removal, including larger benign and invasive malignant types.

    Conclusions:

    • Colonoscopic excision is the primary treatment for most sessile colon polyps, minimizing the need for laparotomy.
    • Careful patient selection and technique are crucial for successful endoscopic management.
    • Laparotomy remains indicated for specific large benign or invasive malignant sessile colon polyps.
