  "abstract": "We read with great interest the recently published study by Groen et al comparing high-definition (HD) dye-based chromoendoscopy (CE) to HD white-light endoscopy (WLE) with segmental re-inspection and single-pass HD WLE in surveillance for colorectal neoplasia (CRN) in inflammatory bowel disease (IBD) patients.1 This multicentre randomised controlled trial addresses a critical clinical question. However, we would like to raise several points for further discussion and consideration.",
