Summary
Brief summary (as posted)
We will conduct a multicenter, parallel-group, non-inferiority RCT in persons with IBD undergoing colorectal neoplasia screening with high-definition white light colonoscopy, comparing a strategy of sampling visible lesions alone to a conventional strategy of sampling both visible lesions as well as normal-appearing mucosa using non-targeted biopsies. The primary outcome is the neoplasia detection rate. The required sample size to demonstrate non-inferiority is 1952 persons.

- Experimental: Intervention Group
- description
- Participants will undergo standard colonoscopy as part of their routine IBD surveillance. During this colonoscopy targeted biopsies (biopsies of any areas suspicious for neoplastic/dysplastic lesions observed by the doctor) and/or removal of any polyps will be undertaken. A limited number of disease staging biopsies from each segment of the colorectum will be permitted.

- Control Group
- description
- Participants will undergo standard colonoscopy as part of their routine IBD surveillance. During this colonoscopy both random (approximately 32 to 40 non-targeted biopsies) and targeted sampling (biopsies and/or removal of suspicious pre-cancerous lesions) will be undertaken.

Inclusion Criteria:
* Each potential participant must satisfy all of the following criteria to be enrolled in the study.
* ≥ 18 years old

Exclusion Criteria:
* Persons who are unable to provide informed consent
* Persons with a history of colorectal cancer
