Study information
Scientific title
Accuracy of Detection using ENdocuff Optimisation of Mucosal Abnormalities
Acronym
ADENOMA
Study hypothesis
It is predicted that using the Endocuff Vision will improve the adenoma detection rate.
Primary objective:
1. To detect a difference in adenoma detection rate between Endocuff-Assisted Colonoscopy (EAC) and Standard Colonoscopy (SC)
Secondary objectives:
1. To detect a difference in mean adenomas detected per procedure (MAP2) between EAC and SC
2. To establish the rate of cuff exchange (that is, how often the cuff has to be removed)
3. To demonstrate non-inferiority of caecal intubation rates and insertion time to caecum between EAC and SC
4. To demonstrate non-inferiority in complete withdrawal time in procedures where no polyps are detected between EAC and SC
5. To demonstrate non-inferiority of patient satisfaction with EAC compared to SC
6. To identify any difference in future colonoscopic workload produced by increased ADR in terms of number of potential follow-up procedures based on BSG adenoma surveillance guidelines between the EAC and SC groups
These outcomes will be analysed on an intention-to-treat basis.

Condition
Conditions requiring colonoscopy assessment, colonic adenomas
Intervention
Two study arms:
1. Control arm - routine colonoscopy performed in standard fashion with no Endocuff Vision attached to scope
2. Intervention arm - colonoscopy performed with Endocuff Vision device attached to end of colonoscope
Intervention will be for the duration of the colonoscopy only. Participants will also complete a patient experience questionnaire immediately after, and within a week after, the procedure. Histology results of any polyps detected will be reviewed by the research team, and 30-day adverse events recorded.

Primary outcome measures
Adenoma detection rate (ADR)
Secondary outcome measures
1. Mean adenomas detected per procedure (MAP)
2. The rate of cuff exchange (that is, how often the cuff has to be removed)
3. Caecal intubation rates and insertion time to terminal ileum (to demonstrate non-inferiority)
4. Complete withdrawal time in procedures where no polyps are detected (to demonstrate non-inferiority)
5. Patient satisfaction
6. To identify any difference in future colonoscopic workload produced by increased adenoma detection rate in terms of number of potential follow-up procedures based on BSG adenoma surveillance guidelines between the EAC and SC groups
