    Rectal ultrasound imaging using radial and linear probes has been employed since 1983 for laboratory and clinical examinations. This study characterized normal endosonographic appearances and evaluated rectal cancer staging accuracy.

    Area of Science:

    • Medical imaging
    • Gastroenterology
    • Surgical oncology

    Background:

    • Radial and linear ultrasound probes have been utilized for rectal examinations since 1983.
    • Characterization of normal endosonographic appearances is crucial for accurate diagnosis.

    Purpose of the Study:

    • To characterize normal endosonographic appearances of the rectum.
    • To evaluate the accuracy of rectal ultrasound in staging rectal cancer.

    Main Methods:

    • Utilized radial and linear ultrasound probes for laboratory and clinical rectal examinations.
    • Examined polyethylene membranes and resection specimens to define normal endosonographic features.
    • Assessed 20 healthy subjects and 11 patients with rectal cancer.

    Main Results:

    Related Experiment Videos

    • Established characteristic normal endosonographic appearances of the rectum.
    • Successfully staged 9 out of 11 rectal cancer patients, indicating significant diagnostic capability.

    Conclusions:

    • Rectal endosonography provides a reliable method for characterizing normal rectal anatomy.
    • Ultrasound-based staging of rectal cancer demonstrates promising accuracy, aiding in treatment planning.
