Brief summary
The purpose of this study was to assess the performance of automatic quality-control system (AQCS) in real-time quality control of colonoscopy.
Detailed description
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.
Interventions
DEVICEComputer-aided Real-time Automatic Quality Control System (AQCS)
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.

Inclusion criteria
* Consecutive patients (aged 18-80 years) scheduled for colonoscopy examination.
Exclusion criteria
* Patients with a history of inflammatory bowel disease, advanced colorectal cancer, polyposis syndromes or known colorectal polyps without complete removal previously. * Patients with a history of colorectal surgery. * Patients with a contraindication for biopsy. * Patients with prior failed colonoscopy. * Patients with known stenosis or obstruction. * Patients in pregnancy or lactation phase. * Patients refused to participate in the trial.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Colorectal adenoma detection rate (ADR) | 10 months | The primary endpoint is the adenoma detection rate (ADR), which is the proportion of patients having one or more adenomas detected by colonoscopy. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Colorectal polyp detection rate (PDR) | 10 months | The polyp detection rate (PDR) is the proportion of patients having one or more polyps detected by colonoscopy. |
| The mean number of adenomas detected per colonoscopy (APC) | 10 months | The mean number of adenomas detected per colonoscopy in AQCS and control groups |
| The mean number of polyps detected per colonoscopy (PPC) | 10months | The mean number of polyps detected per colonoscopy in AQCS and control groups |
| Withdrawl time | During procedure | Withdrawl time is defined as the time taken to remove the colonoscope from the cecal pole minus the time of therapeutic interventions or biopsy, until the complete withdrawal of the colonoscope. |
