In the current economic environment, new techniques and strategies need to show that they are cost-effective for widespread implementation to occur. The authors provide a basic cost–benefit analysis based on the numbers of colonoscopies performed under old and new guidelines but do not consider other costs—specifically, histology and endoscopic equipment costs. Also, it is not clear how they arrived at the numbers in each risk group.

We recently performed an audit of all patients undergoing …
