Impact of Real-time Automatic Quality Control System on Colorectal Adenoma Detection

Not Applicable

• Conditions: Colonoscopy

• Registration Number: NCT04901130
• Lead Sponsor: Shandong University

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.

Primary Outcome Measures

Name	Time	Method
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 Outcome Measures

Name	Time	Method
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.
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.
