Participant Flow

Patients were recruited from general practice or from urgent suspected colorectal cancer referral waiting lists held in secondary care. 114 patients were enrolled in the study from five NHS regions between November 2020 and June 2021.

This was an observational feasibility study with no exclusions after recruitment.

Participant milestones

Participant milestones
Measure
Observational Cohort
1. Patients with an established diagnosis of inflammatory bowel disease who have been identified as being 'at risk' by either their secondary care doctor or GP and now require endoscopic assessment for ongoing disease symptoms but are unable to access endoscopy services urgently. 2. Patients presenting directly to their GP practice with symptoms of anorectal disease (e.g. rectal bleeding or pain) or symptoms that would warrant referral to a hospital under a 2WW appointment according to NICE criteria Recruited patients will undergo rectal examination in primary care with the LumenEye X1 with either contemporaneous or retrospective image review by a secondary care clinician. This will require a glycerine suppository to be administered. Patient feedback will be sought with a post-procedural questionnaire. LumenEye X1 digital rectoscope: The LumenEye X1 is a novel digital rectoscope that introduces digital HD imaging and improved ergonomics to conventional rigid sigmoidoscopy.

SECONDARY outcome

Timeframe: Diagnostic accuracy of the LumenEye examination to be compared with subsequent investigations completed by the time of analysis (2-9 months after study examination).

Population: Patients undergoing colonoscopy, flexible sigmoidoscopy, or CTVC after LumenEye examination.

To provide pilot data within the small study for the diagnostic accuracy of the LumenEye system as compared to conventional flexible endoscopy.
