Patients in AQCS-aided group will go through colonoscopy examination with the assitance of AQCS.

Patients in control group will go through conventional standard colonoscopy examination without the assistance of the 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.

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.

Impact of Real-time Automatic Quality Control System on Colorectal Adenoma Detection: a Multicenter Randomized Controlled Trial

The primary endpoint is the adenoma detection rate (ADR), which is the proportion of patients having one or more adenomas detected by colonoscopy.

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 in AQCS and control groups

The mean number of polyps detected per colonoscopy in AQCS and control groups

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.

Automatic quality-control system could real-time measuring endoscopic inspection completeness, detecting gastric neoplasms and evaluating gastric mucosal visibility.

automatic quality-control system

The aim of our study was to develop an automatic quality-control system and assess the performance of this system in quality control of esophagogastroduodenoscopy.

In this study, the researchers firstly developed an automatic quality-control system, name as EAS. Next, the researchers applied the system in a endoscopic center and designed a prospective randomised controlled trial to investigate the performance of the system in quality control of esophagogastroduodenoscopy.
