An interventional study of conventional colonoscopy procedure and artificial intelligence-assisted colonoscopy procedure in Artificial Intelligence, Colonic Adenoma and Colonic Neoplasms, sponsored by Chirec. Not yet recruiting at 1 site in Belgium. Open to participants aged 45 Years to 74 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-01-24.

Cancer can develop in the colon, or large bowel. Examination of the colon with a tube fitted with a camera is called a colonoscopy.
Colonoscopy allows detection of small growths in the colon, called "polyps". Polyps can often be removed during colonoscopy. Some of these polyps are called adenomas and can become cancer after several years.
A good colonoscopy aims to find and take out as many of these polyps as possible.
A quality indication of colonoscopy is the "adenoma detection rate" (ADR). It should be high, meaning many polyps are detected and taken out.
New artificial intelligence devices to assist colonoscopy seem to increase the ADR, and maybe help prevent cancer even better than normal colonoscopy.
The goal of this clinical trial is to compare the ADR when using standard colonoscopy to the ADR with artificial intelligence (AI)-assisted colonoscopy.
The colon is a part of the bowel where colon cancer can develop.
It is possible to prevent colon cancer by doing a screening test called a colonoscopy.

The goal of this clinical trial is to compare the ADR when using standard colonoscopy to the ADR with artificial intelligence (AI)-assisted colonoscopy.
Patients who are scheduled to have screening colonoscopy and who agree to participate, and are aged 45 years or more, will be randomly assigned to receive either standard colonoscopy or AI-assisted colonoscopy.
The main objective of this study is the difference in the ADR between a conventional colonoscopy procedure and an AI-assisted colonoscopy procedure.
Secondary objectives will compare the 2 groups (conventional colonoscopy and AI-assisted colonoscopy) regarding polyp size, polyp quantity, polyp histology (laboratory analysis of the polyp that was taken out), polyp dysplasia grade (how close the polyp is to cancer), polyp location in the colon, endoscopist experience (older or younger doctor), time of day and colonoscopy preparation quality (how clean the bowel is).
With these results we can show that AI-assisted colonoscopy is useful or not to help better prevent colon cancer.
Exclusion criteria:
The conventional colonoscopy arm subjects will undergo a screening colonoscopy without assistance from artificial intelligence.
Other: conventional colonoscopy procedure
The artificial intelligence-assisted colonoscopy arm subjects will undergo a screening colonoscopy with assistance from an artificial intelligence module.
Other: artificial intelligence-assisted colonoscopy procedure
Study subjects in this interventional arm will undergo conventional colonoscopy.
Study subjects in this interventional arm will undergo colonoscopy done with a commercially-available module that uses artificial intelligence to highlight suspected polyps on the screen during colonoscopy. This module also attempts to characterize the detected polyp as adenomatous or not. The detection and characterization of polyps is in real time, during the procedure.
Adenoma Detection Rate in Conventional versus Artificial Intelligence-Assisted Colonoscopy
The main objective of this study is the difference in the detection rate of colorectal adenomas in individuals over 45 years old during colonoscopies for colon cancer screening between a conventional colonoscopy procedure (CCP) and a colonoscopy procedure with AI (ACP).
Time frame: 1 day
The difference in the detection rate of colorectal adenomas according to size by group (5 mm/6-9 mm/>10 mm) between a conventional colonoscopic procedure (CCP) and a colonoscopy procedure with AI (ACP).
Detection rate of diminutive, small, and large polyps will be compared between a conventional colonoscopic procedure (CCP) and a colonoscopy procedure with AI (ACP).
Time frame: 1 day
The difference in the detection rate of colorectal adenomas according to the number per group (n=1-2/n= 3-10/n >10) between a conventional colonoscopic procedure (CCP) and a colonoscopy procedure with AI (ACP).
The number of adenomas detected during the procedure will be compared between a conventional colonoscopic procedure (CCP) and a colonoscopy procedure with AI (ACP).
Time frame: 1 day
The difference in the detection rate of colorectal adenomas based on histology by group (hyperplastic/conventional adenomas/serrated adenomas/adenocarcinoma) between a conventional colonoscopic procedure (PCC) and a colonoscopy procedure with AI.
Adenomas have different histologic types. After obtaining histology, the detection rate of the various histologic types will be compared between a conventional colonoscopic procedure (CCP) and a colonoscopy procedure with AI (ACP).
Time frame: 1 month
The difference in detection rate of colorectal adenomas based on dysplastic grade by group
The difference in detection rate of colorectal adenomas based on dysplastic grade by group (conventional or serrated adenomas/low-grade dysplasia/high-grade dysplasia/adenocarcinoma) or Narrow Band Imaging International Colorectal Endoscopic (NICE) (stages 1, 2 or 3) classification or Japan Narrow Band Imaging Expert Team (JNET) classification (stages 1, 2A and 2B, or 3) between a conventional colonoscopy procedure (CCP) and a colonoscopy procedure with AI (ACP).
Time frame: 1 day
The difference in the detection rate of colorectal adenomas depending on the location by group (rectum/left colon/transverse colon/right colon) between a conventional colonoscopic procedure (CCP) and a colonoscopy procedure with AI (ACP).
Location of adenomas will be compared between a conventional colonoscopic procedure (CCP) and a colonoscopy procedure with AI (ACP).
Time frame: 1 day
The difference in the detection rate of colorectal adenomas according to experience by group of colonoscopists
The difference in the detection rate of colorectal adenomas according to experience by group (Colonoscopists aged 45-55 years/56-65 years/\>66 years) between a conventional colonoscopic procedure (CCP) and a conventional colonoscopic procedure (CCP) colonoscopy with AI (ACP).
Time frame: 1 day
The difference in the detection rate of colorectal adenomas depending on the time of day .

Time frame: 1 day
Plan to share: Yes — Individual Participant Data will include anonymized demographic information, clinical outcomes, laboratory results, and recorded adverse events. Access to the data will be available to qualified researchers, with requests submitted by contacting one of the investigators. The investigators will employ strict data protection measures, ensuring all shared data is de-identified and in compliance with applicable data protection laws. Access to the individual participant data will be contingent on the signing of a data sharing agreement that outlines the intended use of the data and adherence to ethical guidelines.
