Endoscopic polypectomy. Therapeutic and clinicopathologic aspects.

W I Wolfe, H Shinya

    Cancer
    |August 1, 1975
    PubMed
    Summary

    Endoscopic removal of neoplastic colonic polyps is now a safe and effective technique. This approach reduces the need for surgery, with malignant changes found in 10.5% of polyps analyzed.

    Area of Science:

    • Gastroenterology
    • Surgical Oncology
    • Pathology

    Background:

    • Neoplastic colonic polyps pose a malignant risk.
    • Endoscopic techniques offer a less invasive alternative to surgery.

    Purpose of the Study:

    • To re-assess the malignant potential of colonic polyps.
    • To clarify indications for surgical intervention after endoscopic polyp removal.

    Main Methods:

    • Analysis of over 2000 endoscopically removed polyps.
    • Review of pathological findings, differentiating carcinoma in situ from invasive cancer.

    Main Results:

    • Endoscopic polyp resection demonstrated a low complication rate (one surgery in over 2000 cases).
    • Malignant change was observed in 10.5% of neoplastic polyps (855 analyzed).
    • Superficial cancers (carcinoma in situ) did not require further treatment beyond polyp removal.

    Conclusions:

    • Endoscopic resection is a primary treatment for most colonic polyps.
    • Laparotomy is reserved for polyps unsuitable for endoscopic removal or when residual cancer is suspected.
    • Colonoscopy is crucial for follow-up after polyp management, regardless of the resection method.
