Sigmoidoscopy

R J Nicholls

    British Journal of Hospital Medicine

    Summary
    This summary is machine-generated.

    Rigid sigmoidoscopy is standard for anorectal exams, but flexible sigmoidoscopy examines more bowel and finds more abnormalities. For complete large bowel evaluation, barium enema and colonoscopy are needed.

    Area of Science:

    • Gastroenterology
    • Medical Imaging

    Background:

    • Rigid sigmoidoscopy is a routine part of anorectal examinations.
    • It allows for inspection of the rectum in most cases.

    Purpose of the Study:

    • To compare the diagnostic yield of rigid versus flexible sigmoidoscopy.
    • To determine the necessity of further imaging for complete large bowel examination.

    Main Methods:

    • Review of diagnostic capabilities of rigid sigmoidoscopy.
    • Evaluation of flexible sigmoidoscopy for outpatient examination.
    • Assessment of the role of air-contrast barium enema and colonoscopy.

    Main Results:

    • Flexible sigmoidoscopy examines a greater extent of the bowel compared to rigid sigmoidoscopy.
  • Flexible sigmoidoscopy leads to the discovery of more abnormalities.
  • Neither sigmoidoscopy technique provides complete examination of the large bowel.

    • Conclusions:

    • Flexible sigmoidoscopy is a practical outpatient procedure with a higher diagnostic yield.
    • Air-contrast barium enema and colonoscopy are essential for detecting proximal large bowel disease.
