Abstract:Objective To make a quantitative analysis of the influence of artificial intelligence (AI) assisted colonoscopy on polyp detection.Methods As of May 2021, the research related to AI-assisted colonoscopy in Cochrane Library, PubMed, Embase, Web of Science, CNKI, Wanfang Data, and VIP were searched, and the quality of the articles was evaluated. RevMan 5.4 software was used for Meta-analysis.Results 8 literatures were included, including 6 217 cases (3 095/3 122). Compared with colonoscopy without AI, colonoscopy with AI increased the detection rate of adenoma (ADR) (RR^ = 1.43, 95%CI: 1.33 ~ 1.55, P = 0.000); Improved polyp detection rate (PDR) (RR^ = 1.40, 95%CI: 1.30~1.51, P = 0.000). ADR and PDR were significantly increased in left and right colon, < 10 mm and pedunculated colon (P < 0.01); There was no significant difference in the observation time between AI assisted colonoscopy and routine colonoscopy.Conclusion AI assisted enteroscopy can increase the detection rate of adenomas and polyps, which is related to the location, size and morphology of adenomas and polyps, and has nothing to do with the time of withdrawal.
