231

Results

We analyzed data for 231 patients (Group A, n=113; Group B, n=118). The ADR was not significantly different between the two groups. Group A had a significantly lower AMR (25.6% vs. 38.6%, p=0.033) and number of missed adenomas per patient (0.5 vs. 0.9, p=0.004) than Group B.

Baseline Characteristics

The patients in this multicenter randomized controlled trial were divided into Group A (observation using CAD EYE) and Group B (standard observation). Six trainees performed colonoscopies using a back-to-back method in pairs with gastroenterology experts. The primary endpoint was the trainees' adenoma detection rate (ADR), and the secondary endpoints were the trainees' adenoma miss rate (AMR) and Assessment of Competency in Endoscopy (ACE) tool scores. Each trainee's learning curve was evaluated using a cumulative sum (CUSUM) control chart.

Participant flow

The study involved adults aged >20 years who were scheduled for outpatient colonoscopy from May 2021 to March 2022. The colonoscopy examinations were performed either because of a positive fecal immunochemical test or for surveillance after colonic polypectomy. We excluded patients with ileus, suspected bowel obstruction, or toxic megacolon; prior abdominal or pelvic surgery; inflammatory bowel disease; advanced malignancy; severe liver damage (Child-Pugh gradeC); dementia or other cognitive disorders; hypersensitivity to bowel preparation drugs for colonoscopy; and pregnancy or lactation.

Adverse events

No perioperative severe adverse events were observed in this study.

Outcome measures

We analyzed data for 231 patients (Group A, n=113; Group B, n=118). The ADR was not significantly different between the two groups. Group A had a significantly lower AMR (25.6% vs. 38.6%, p=0.033) and number of missed adenomas per patient (0.5 vs. 0.9, p=0.004) than Group B. Group A also had significantly higher ACE tool scores for pathology identification (2.26 vs. 2.07, p=0.030) and interpretation and identification of pathology location (2.18 vs. 2.00, p=0.038). For the CUSUM learning curve, Group A showed a trend toward a lower number of cases of missed multiple adenomas by the six trainees.
