Colonoscopy Clinical Trial
Official title:
Artificial Intelligence-assisted Colonoscopy for Detection of Colon Polyps: a Prospective Randomized Cohort Study
All subjects shall sign informed consent before screening, and subjects shall be included
according to inclusion and exclusion criteria.
A total of four endoscopists were included in the study, two in each group of senior
endoscopists and two in each group of junior endoscopists.
Patients were randomly enrolled into the senior endoscopy group and the junior endoscopy
group, and received artificial intelligence assisted colonoscopy and conventional colonoscopy
successively. The two colonoscopy methods were performed back to back by different endoscopy
physicians with the same seniority.
All patients were examined and treated according to routine medical procedures. The routine
colonoscopy group and the artificial-intelligence-assisted colonoscopy group made detailed
records of the patients' withdrawal time, entry time, number of polyps detected, polyp Paris
classification, polyp size, polyp shape, polyp location and intestinal preparation during the
colonoscopy process
This is a prospective randomized clinical study.This study was conducted in the Endoscopy
Center of the Nanfang Hospital, China. Routine bowel preparation consisted of 4 L of
polyethylene glycol, given in split doses. Colonoscopies were performed with high definition
colonoscopes and high-definition monitors.
All subjects shall sign informed consent before screening, and subjects shall be included
according to inclusion and exclusion criteria.
A total of four endoscopists were included in the study, two in each group of senior
endoscopists (>1000 colonoscopies) and two in each group of junior endoscopists ( <1000
colonoscopies).
Patients were randomly enrolled into the senior endoscopy group and the junior endoscopy
group, and received artificial intelligence assisted colonoscopy and conventional colonoscopy
successively. The two colonoscopy methods were performed by different endoscopy physicians
back to back with the same seniority.
All patients were examined and treated according to routine medical procedures (outpatient
patients and inpatients who did not sign the consent form for polypectomy were not resected
for the lesions detected during the examination, while inpatients who signed the consent form
for polypectomy were left in the original position after the first colonoscopy and removed at
the end of the second examination).
The routine colonoscopy group and the artificial-intelligence-assisted colonoscopy group made
detailed records of the patients' withdrawal time, entry time, number of polyps detected,
polyp Paris classification, polyp size, polyp shape, polyp location and intestinal
preparation during the colonoscopy process.
