High compliance rates observed for follow up colonoscopy post polypectomy are achievable outside of clinical trials: efficacy of polypectomy is not reduced by low compliance for follow up

Introduction  The National Polyp Study demonstrated that removal of adenomas with at least a three‐year follow up reduced the incidence of colorectal cancer. However, compliance with follow up colonoscopy may affect the estimates of reduction in colorectal cancer incidence demonstrated by the National Polyp Study. While an 80% compliance rate for follow up colonoscopy was achieved during the National Polyp Study, the compliance rate for follow up colonoscopy is unknown in the general population. The aim of this study was to determine the compliance rate for follow up colonoscopy and factors which affect follow up.
