Better detection of colon growths is maintained by ongoing review of colonoscopy results

Polyp detection increased from 40.7% in 2004 to 62.2% in 2019.

• The removal rate of polyps larger than 1 cm remained constant at 11%.
• Adenoma detection rates rose from 25.8% in 2012 to 28.3% in 2019.
• Sessile serrated polyp detection rates increased from 4.5% to 14.7%, primarily in the first two years of the audit.
• A significant correlation exists between adenoma detection rates and the mean number of adenomas (r=0.72, p=0.004).
• A strong correlation is observed between sessile serrated polyp detection and the mean number of SSPs (r=0.85, p=0.0001).
