Sponsored by Limian Er · Observational
The investigators conducted a multicenter randomized controlled trial to explore the adjuvant effect of artificial intelligence in the detection of precancerous lesions in the proximal colon.This is a prospective, multicenter, single-blind, parallel randomized controlled trial.During the colonoscopy retraction process, the investigators aimed to compare the detection rates of proximal colon adenomas with and without the assistance of an AI(Artificial Intelligence) diagnostic device.
387 studies on the registry are indexed under Abdominal Pain; 58 are open to participants now.
This study's planned enrollment of 1,200 is above the median of 127 across 80 observational studies indexed under Abdominal Pain.

Procedure: AI group
Procedure: Serial group
Procedure: Standard colonoscopy group
Full AI assistance was used throughout the standard colonoscopy procedure.
After normal withdrawal of the colonoscope to the splenic flexure during standard colonoscopy, full AI assistance was initiated. The colonoscope was re-entered to the ileocecal region for observation. Any missed lesions were recorded.
The standard colonoscopy procedure was performed as usual
Adenoma detection rate
The proportion of patients who have at least one adenoma detected during colonoscopy examination
Time frame: Day 1
Average adenoma detection rate
The result is the number of adenomas detected by colonoscopy divided by the total number of colonoscopies performed.
Time frame: Day 1
Start is estimated for Feb 2026; primary completion for Aug 2028, 29 months later.
Of 28 non-industry observational studies under Abdominal Pain, half reached primary completion within 18 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 38. This study's planned 29 months is above that.
Counting every sponsor, half of 37 studies reached it within 16 months; a quarter within 7 and three quarters within 38.
