Limiting total colonoscopy may reduce costs by 75% while missing only 7.5% of colorectal cancers. Focusing on patients with bleeding or inflammatory bowel disease (IBD) can optimize resource allocation.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Health Economics

Background:

  • Total colonoscopy is the gold standard for colorectal examination but faces rising costs.
  • High costs may limit future access to comprehensive colonoscopies.
  • An alternative approach is needed to balance cost-effectiveness and diagnostic yield.

Purpose of the Study:

  • To evaluate the cost-effectiveness of a limited colonoscopy program.
  • To determine the proportion of lesions missed with a selective approach.
  • To identify a rational strategy for reducing colonoscopy costs.

Main Methods:

  • Retrospective analysis of 1426 colonoscopies performed over 15 years.
  • Assessment of lesion detection rates based on colonoscopy extent.

  • Comparison of lesion location in relation to symptoms and diagnostic findings.

    • Main Results:

    • Total colonoscopy was achieved in 79% of patients.
    • 75% of lesions were located in or distal to the descending colon.
    • Flexible sigmoidoscopy would miss only 7.5% of colorectal cancers.
    • A selective approach could reduce colonoscopy costs by 75%.

    Conclusions:

    • A selective colonoscopy strategy focusing on bleeding or inflammatory bowel disease (IBD) patients is cost-effective.
    • This approach significantly reduces costs while minimizing the missed cancer rate.
    • This compromise offers a rational method to manage colonoscopy expenses.
