Post-polypectomy surveillance colonoscopy: Comparison of the updated guidelines

Area of Science:

• Gastroenterology
• Endoscopy
• Oncology

Background:

• Three updated guidelines for post-polypectomy colonoscopy surveillance (PPCS) have been published.
• These guidelines are based on a comprehensive literature review.
• While some recommendations overlap, differing surveillance intervals exist for specific polyp types.

Purpose of the Study:

• To compare and contrast the recommendations of the updated PPCS guidelines.
• To highlight key differences in surveillance strategies for various polyp findings.

Main Methods:

• A review of the updated PPCS guidelines was conducted.
• Recommendations from different guidelines were systematically compared.

Main Results:

• For low-risk adenomas or serrated polyps, European and UK guidelines recommend routine CRC screening, whereas the USMSTF suggests 7-10 year surveillance for 1-2 tubular adenomas.
• USMSTF classifies adenomas with villous histology as high-risk (3-year surveillance), a distinction not made by ESGE/BSG.
• USMSTF recommends 5-10 year surveillance for 1-2 sessile serrated polyps (SSPs) and 3-5 years for 3-4 SSPs.

Conclusions:

• Significant discrepancies exist in post-polypectomy colonoscopy surveillance recommendations across major guidelines.
• These differences, particularly regarding risk stratification and surveillance intervals, may impact patient management and colorectal cancer (CRC) prevention strategies.
