Abdominal Pain, Black Stools, Constipation, Diarrhea
Conditions
Brief summary
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.
Interventions
PROCEDUREAI group
Full AI assistance was used throughout the standard colonoscopy procedure.
PROCEDURESerial group
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.
PROCEDUREStandard colonoscopy group
The standard colonoscopy procedure was performed as usual

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Average adenoma detection rate | Day 1 | The result is the number of adenomas detected by colonoscopy divided by the total number of colonoscopies performed. |
| Adenoma detection rate | Day 1 | The proportion of patients who have at least one adenoma detected during colonoscopy examination |
