Table 1. Patient information.

A total of 103 IBD patients who underwent surveillance colonoscopy were recruited, of whom 20 were identified as high risk while 83 were low risk. Of the 20 high risk patients, 6 had colonic biopsies indefinite for dysplasia, 2 had sessile serrated adenomas, 10 had tubular adenomas, while 2 harbored high-grade dysplasia. The table compares the clinical and endoscopic outcomes of low- and high-risk IBD patients along with their demographics.
