The Impact Of Artificial Intelligence On The Adenoma Detection Rate (ADR): A Comparison Between Experienced And Trainee Endoscopists’ ADR

Aims Colorectal cancer (CRC) is the second most common cause of cancer death in the European Union. Most cases of CRC arise out of adenomas, which could be easily treated in a timely manner by endoscopic removal. Many studies have proven that a high adenoma detection rate (ADR) reduces the incidence of CRC. Artificial Intelligence (AI) is a promising new tool to achieve a high ADR. The aim of this study is to evaluate the impact of AI on the frequency of adenoma detection by endoscopists in training in comparison to the frequency of detection by senior endoscopists.

Methods Data from all patients who underwent colonoscopy with a GI Genius enhanced colonoscope were collected within a period of two months. Endoscopists were divided into two groups, a trainee group (7 endoscopists; < 500 colonoscopies) and an expert group (4 endoscopists; > 1000 colonoscopies). The polyp and adenoma detection rates of both groups were calculated and compared using cross tabulation and the chi-square test.

Results So far 150 patients (77 male, 73 female), mean age: 60 (SD± 16) years have been included. The most common indications for colonoscopy were screening (21,3 %), surveillance (17,3 %), GI disturbances (12,7 %), bleeding/anemia (12 %), CED (10,7 %) and elective polypectomy (10 %). Most procedures were done by the trainee group (n = 94). In total 311 polyps were removed. The polyp detection rate (PDR) was 69,1 % in the trainee group and 67,9 % in the expert group. The adenoma detection rate was 48,9 % in the trainee group and 46,4 % in the expert group. There was no significant difference between both groups in terms of PDR (p = 0,869) and ADR (p = 0,766).

Conclusions Our interim analysis shows that Artificial Intelligence can help to minimize the difference of ADR between experienced and trainee endoscopists.
