人工智能辅助结肠镜检查对息肉检出率影响的Meta分析

Impact of artificial intelligence assisted colonoscopy on polyp detection rate: a Meta-analysis

摘要:

目的 定量分析人工智能（AI）辅助结肠镜检查对息肉检出率的影响。方法 检索自建库至2021年5月Cochrane Library、PubMed、Embase、Web of Science、中国知网（CNKI）、万方数据（Wanfang Data）和维普网（VIP）中关于AI辅助结肠镜检查的研究，并对文章进行质量评价，采用RevMan 5.4软件进行Meta分析。结果 纳入8篇文献，共6 217例患者（3 095/3 122）。与没有AI辅助的结肠镜检查相比，AI辅助结肠镜检查增加了腺瘤检出率（ADR）（RR＾ = 1.43，95%CI：1.33～1.55，P = 0.000），提高了息肉检出率（PDR）（RR＾ = 1.40，95%CI：1.30～1.51，P = 0.000）。左半结肠、右半结肠、 < 10 mm和无蒂的ADR和PDR明显增加（P < 0.01）；AI辅助结肠镜与常规结肠镜检查退镜观察时间无明显差异。结论 AI辅助肠镜检查可以增加腺瘤和息肉的检出率，与腺瘤及息肉的位置、大小及形态学相关，与退镜时间无关。

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.
