    Summary
    This summary is machine-generated.

    Total colonoscopy detected 199 colorectal cancers in 3940 patients over four years. Early detection and endoscopic removal of these cancers, especially in the rectum and sigmoid colon, are crucial for effective treatment.

    Area of Science:

    • Gastroenterology
    • Oncology
    • Endoscopy

    Context:

    • Over a four-year period, 4708 total colonoscopies were performed on 3940 outpatients.
    • Colorectal cancer screening and diagnosis are significant public health concerns.

    Purpose:

    • To evaluate the efficacy of total colonoscopy in detecting colorectal carcinomas.
    • To highlight the importance of endoscopic polypectomy for malignant potential treatment.

    Summary:

    • 199 colorectal carcinomas were detected, including 72 focal, 46 invasive, and 81 advanced stages.
    • 8 early-stage colorectal cancers were identified, even in diminutive lesions under 5 mm.
    • The majority of colorectal carcinomas (74.4%) were located in the rectum and sigmoid colon, with 13.1% in the right colon.
