Abstract:Objective To investigate the influencing factors of polyp detection rate (PDR) and the role of artificial intelligence in high-risk population in community colorectal carcinoma (CRC) screening.Methods 202 patients with CRC screening positive from December 2020 to March 2021 were selected and subjected to colonoscopy. PDR was compared according to the clinical characteristics, quality of bowel preparation, and ENDOANGEL-assisted diagnoses.Results The PDR was 37.62% in this study. Univariate analysis showed that the age of the detection group was elder than that of the non-detection group [(61.26 ± 6.45) and (58.37 ± 7.01) years old, P = 0.004), the weight of the detection group was higher than that of the non-detection group [(65.28 ± 9.51) and (60.81 ± 9.20) kg, P = 0.001), the body mass index (BMI) of the detection group was higher than that of the non-detection group [(24.80 ± 2.69) and (23.51 ± 2.96) kg/m2, P = 0.002], the proportion of males was higher than that of the non-detection group (38.16% and 24.60%, P = 0.041), the proportion of chronic diarrhea or constipation symptoms was 42.11%, while the non-detection group was 55.56%, with no statistically significant difference (P = 0.064), and the proportion of using of ENDOANGEL-assisted diagnosis was higher than that of the non-detection group (67.11% and 43.65%, P = 0.001). Multivariate analysis showed that age (OR^ = 1.066, 95%CI: 1.017 ~ 1.119, P = 0.008) and the use of ENDOANGEL (OR^ = 3.101, 95%CI: 1.625 ~ 5.916, P = 0.001) were independent influencing factors to PDR. For the further analysis of the ENDOANGEL-assisted group, it was found that age, body weight, BMI, withdrawal time, intestinal preparation score and gender had an impact on PDR. Withdrawal time (OR^ = 1.007, 95%CI: 1.001 ~ 1.013, P = 0.027) and intestinal preparation score (OR^ = 1.535, 95%CI: 1.018 ~ 2.316, P = 0.041) were independent predictors.Conclusion For high-risk patients who are screened for CRC, male, elderly, and obese patients have a greater risk of polyps. Improving the intestinal preparation score and extending the withdrawal time when using ENDOANGEL assistance for diagnosis may be more helpful in detecting lesions.
