Core Tip

Core Tip: This study is the first systematic review and meta-analysis to separately evaluate the potential risk between post-inflammatory polyps (PIPs) and colorectal neoplasia, advanced colorectal neoplasia, and colorectal cancer. Interestingly, we found that although malignant transformation from PIPs is rare, inflammatory bowel disease (IBD) patients with PIPs still bear an increased incidence of various grades of colorectal neoplasia. As an early warning of the increasing risk of colorectal neoplasia, IBD patients with PIPs should undergo strengthened surveillance to detect early dysplastic changes to allow for appropriate management so that there are improvements in both quality of life and survival rates.
