This is a prospective, multicenter randomized controlled trial designed to determine whether the use of computer-aided detection system could reduce the miss rates of adenomas, SSLs, and polyps in the proximal colon during tandem colonoscopy.
This is a prospective, multicenter, tandem randomized controlled trial conducted at 8 endoscopy centers in China (Guangdong). Participants are randomized at a 1:1 ratio to undergo either CADe-assisted colonoscopy first or conventional white-light colonoscopy first. The second colonoscopy is performed immediately afterward in tandem fashion by the same endoscopist.
A variable-block randomization design with block sizes ranging from 4 to 6 was adopted. The random sequence was generated in advance by the lead center using a digital random number generator to allocate participants to study groups. After successful cecal intubation and confirmation of adequate right sided bowel cleaning, the performing operator was informed of the group allocation by the trained research assistants. All participants, pathologists, and statisticians remained blinded to group allocation throughout the study.

Ran from Dec 2025 to primary completion in May 2026, 4 months.
Of 132 non-industry interventional studies with no phase under Colonic Polyps, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 35. This study's 4 months is below that.
Counting every sponsor, half of 149 studies reached it within 17 months; a quarter within 9 and three quarters within 35.
Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 22, 2026: primary completion May 2027 → May 2026 and completion Jul 2027 → May 2026.
