The purpose of this study was to assess the performance of automatic quality-control system (AQCS) in real-time quality control of colonoscopy.
We carried a multicenter randomised controlled trial to assess the performance of this system in quality control of real-time colonoscopy, including the adenoma detection rate (ADR), withdraw time, adequate bowel preparation rate and other indicators.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| AQCS-aided group | Experimental | Patients in AQCS-aided group will go through colonoscopy examination with the assitance of AQCS. |
|
| Control group | No Intervention | Patients in control group will go through conventional standard colonoscopy examination without the assistance of the AQCS. |

| Computer-aided Real-time Automatic Quality Control System (AQCS) | Device | Automatic quality-control system(AQCS), developed based on deep convolutional neural network (DCNN) models, could improve the colonoscopists' performance during withdrawal phase and significantly increase polyp and adenoma detection. |
| Measure | Description | Time Frame |
|---|---|---|
| Colorectal adenoma detection rate (ADR) | The primary endpoint is the adenoma detection rate (ADR), which is the proportion of patients having one or more adenomas detected by colonoscopy. | 10 months |
| Measure | Description | Time Frame |
|---|---|---|
| Colorectal polyp detection rate (PDR) | The polyp detection rate (PDR) is the proportion of patients having one or more polyps detected by colonoscopy. | 10 months |
| The mean number of adenomas detected per colonoscopy (APC) |
