Colonic polyps: are we ready to resect and discard?

Area of Science:

• Gastroenterology
• Oncology
• Health Economics

Background:

• Colorectal cancer is a leading cause of death in Western nations.
• Colonoscopy screening is recommended by official guidelines.
• Polypectomy of small lesions significantly impacts screening costs.

Purpose of the Study:

• To review the evidence for a "resect and discard" strategy for diminutive polyps (≤5 mm).
• To evaluate the clinical utility and cost-effectiveness of this approach.
• To identify potential challenges and limitations of the "resect and discard" method.

Main Methods:

• Literature review of studies on diminutive polyp management.
• Analysis of cost-benefit data for pathologic examination versus "resect and discard".
• Evaluation of diagnostic accuracy and safety of the strategy.

Main Results:

• Pathologic examination of diminutive polyps is costly, with low prevalence of advanced neoplasia.
• Differentiating adenomatous from hyperplastic polyps is the primary justification for current pathology practices.
• The "resect and discard" strategy shows potential for cost savings but requires careful implementation.

Conclusions:

• The "resect and discard" strategy for diminutive polyps may offer economic benefits in colonoscopy screening.
• Careful consideration of diagnostic accuracy and potential pitfalls is crucial for successful implementation.
• Further research may refine guidelines for managing diminutive polyps to optimize screening efficiency and cost-effectiveness.
