The incidence of colorectal cancer (CRC) is high in France, with approximately 45,000 new cases per year. The fecal immunochemical test (FIT) is used for screening for this cancer. If the test is positive, a colonoscopy is recommended.

In recent years, French and European societies of digestive endoscopy have defined quality criteria for colonoscopy to reduce the risk of interval colorectal cancer (ICRC), that is, CRC occurring within 5 years of a colonoscopy considered negative. The operator's adenoma detection rate (ADR) is one of these factors. Its threshold is set at 45% within the framework of the organized CRC screening program, i.e., after a positive FIT.

Artificial intelligence is emerging as an effective way to increase operators' ADR. Balloon-assisted endoscopy (G-Eye) also increases the TDA (transient anaerobic digestion).

No French data are available regarding G-Eye, and there is limited data concerning CAD-Eye (artificial intelligence). No data exist on the combination of these two devices. Therefore, there is no data on the combination of these devices during a colonoscopy performed after a positive TIF (transient anaerobic digestion) test.

It should be noted that all published studies were conducted in expert centers. The value of this study lies in its ability to collect real-world data.
