A trial looking at two different types of endoscope

Please note - this trial is no longer recruiting patients. We hope to add results when they are available.

Cancer type:

Bowel (colorectal) cancer





This trial is for people who are taking part in the Bowel Cancer Screening Programme (BCSP) and may be offered a test called a colonoscopy.

As part of the bowel cancer screening programme you have been offered a test called a colonoscopy. This test uses a camera on the end of a flexible tube (endoscope) to look at the inside of your bowel.

Doctors look for and remove small growths called polyps Open a glossary item that may develop into cancer in the future. So removing bowel polyps reduces your risk of bowel cancer.

In this trial researchers want to compare 2 makes of camera (endoscope) to find out if one is better than the other.

The aim of this trial is to find out if one endoscope is better than the other at helping doctors to

  • See the bowel more clearly and identify any suspicious areas
  • See polyps
  • Remove polyps
  • Do the colonoscopy more easily and so cause less discomfort

Who can enter

You may be able to enter this trial if you

  • Have been offered a colonoscopy as part of the National Bowel Cancer Screening Programme
  • Are having your colonoscopy at, University College Hospital London or Cambridge University Hospitals NHS Foundation Trust

You cannot enter this trial if you are unable to have a colonoscopy.

Trial design

This trial will recruit 364 people. It is a randomised trial. The people taking part will be put in to one of 2 groups

  • Group 1 have a colonoscopy using a Olympus Lucera System endoscope
  • Group 2 have a colonoscopy using a Pentax HiLine endoscope

The procedure for having the colonoscopy is the same for both groups.

Hospital visits

There are no extra hospital visits.

Side effects

As you would be having a colonoscopy anyway as part of the national screening programme, no extra side effects are expected as a result of taking part in the trial. We have more information about colonoscopy.
