There are about 43,000 new cases of bowel cancer each year in the UK and about 16,000 people die from the disease each year, Prof Rees said.
A total of 2,032 patients from 10 centres across the UK took part in the trial.
The research found the AI device identified at least one adenoma in an extra eight out of 100 people and did not increase the risk of complications.
"We now use this technology routinely in our practice and I really hope that it will be used more widely," said Prof Rees.
"The fantastic thing about using AI is that it learns. It is trained by looking at images.
"It’s adding to its knowledge all the time, so it’s only going to get better."
