Results

The ADR was 59.4% in the CADe group and 47.6% in the control group (p = 0.018). The AMRrs was 11.9% in the CADe group and 26.0% in the control group (p = 0.037). The colonoscopy with the CADe system yielded an 11.8% higher ADR than that performed by experienced endoscopists alone. Moreover, there was no need to extend the examination time or request the assistance of additional medical staff to achieve this improved effectiveness.

Baseline Characteristics

We enrolled 415 subjects who under went colonoscopy at our institution from January 2021 to March 2022. The basic demographic and procedural characteristics of the CADe and control groups were as follows: mean age, 54.9 and 55.9 years; male sex, 73.9% and 69.7% of participants; and mean withdrawal time, 411.8 and 399.0 s, respectively.

Participant flow

We enrolled 415 subjects who under went colonoscopy at our institution from January 2021 to March 2022. The eligibility criteria were as follows: (1) aged from 21 to 81 years old on the date of colonoscopy;(2) patients undergoing endoscopy as a primary endoscopic screening for CRC; (3) patients who tested positive for the fecal immunochemical test (FIT) for occult blood; (4) patients with colorectal neoplasia undergoing endoscopic resection; and (5) willingness to participate in the RCT. In contrast, the exclusion criteria included patients who (1) underwent colorectal surgery and (2) had an inflammatory bowel disease. The randomization method used in this study was the numbered container method according to the CONSORT guideline. The allocation message was generated by the computer program of the Python random module and then sealed in sequentially numbered identical containers according to the allocation sequence. After an eligibility check, the endoscopist opened theallocation message, and subsequently, examinees were randomly assigned to the CADe or control groups.

Adverse events

None

Outcome measures

The ADR was 59.4% in the CADe group and 47.6% in the control group (p = 0.018). The AMRrs was 11.9% in the CADe group and 26.0% in the control group (p = 0.037).
