Outcome Measures

Primary Outcomes (1)

  • Adenoma Detection Rate

    Proportion of examinations expressed as a percentage where at least one adenoma is found

    Day of procedure

Secondary Outcomes (12)

  • Mean adenomas detected per procedure

    Day of procedure

  • Rate of cuff exchange

    Day of procedure

  • Non-inferiority of complete withdrawal time in procedures where no polyps are detected

    Day of procedure

  • Compare overall procedure time between groups

    Day of procedure

  • Measure differences in ADR accounting for patient procedure based variables (e.g. accounting for extent of examination and bowel preparation).

    Day of procedure

  • +7 more secondary outcomes

Study Arms (2)

Endocuff-assisted Flexible Sigmoidoscopy

EXPERIMENTAL

Patients in this arm will receive their screening sigmoidoscopy with the Endocuff Vision in situ on the scope

Device: Endocuff Vision

Standard Flexible Sigmoidoscopy

NO INTERVENTION

Patients in this arm will receive their screening sigmoidoscopy without the Endocuff on the scope

Interventions

The EndocuffTM (ARC Medical Design Ltd and Diagmed, UK) is a device (CE marked in UK) made of a soft plastic material with a unique dynamic shape. Endocuff Visionâ„¢ is placed snugly around the colonoscope tip prior to insertion. It does not project beyond the tip of the scope, providing an unrestricted view. It helps anchor the scope tip against the bowel wall to provide a stable platform of access. The soft, elastic projections are pushed back (recoiled) towards the scope shaft during insertion but evert during withdrawal to hold colon folds away from the field of view.

Eligibility Criteria

Age55 Years - 61 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Age 18 years and over
  • Referral for screening flexible sigmoidoscopy
  • Ability to give informed consent

You may not qualify if:

  • Absolute contraindications to flexible sigmoidoscopy
  • Established or suspicion of large bowel obstruction or pseudo-obstruction
  • Known colon cancer or polyposis syndromes
  • Known colonic strictures
  • Known severe diverticular segment (that is likely to impede sigmoidoscope passage)
  • Patients with known active colitis (ulcerative colitis, Crohn's colitis, diverticulitis, infective colitis)
  • Patients lacking capacity to give informed consent
  • Patients who are on clopidogrel, warfarin, or other new generation anticoagulants which have not been stopped for the procedure as these will preclude polyp removal
  • Pregnancy
