目的:探讨内镜精灵在结肠镜检查中对结肠息肉检出的价值。方法:选取2016年11月—2018年12月于武汉大学人民医院消化内镜中心接受电子结肠镜检查的患者资料共18 667例，按时间段分为5组：A组3 131例(2016年11月—2017年4月)，B组3 703例(2017年5—9月)，C组3 134例(2017年10月—2018年2月)，D组4 347例(2018年3—7月)，E组4 352例(2018年8—12月)，进行回顾性分析。A、B、C组单纯行电子结肠镜检查，D、E组应用内镜精灵行电子结肠镜检查。对各组息肉检出率，大、小息肉检出个数进行统计分析。结果:18 667例患者中5 770例患者检出息肉，共检出息肉18 797个。A、B、C 3组息肉检出率分别为21.88%(685/3 131)、26.55%(983/3 703)、22.94%(719/3 134)，检出小息肉个数占比分别为87.31%(2 161/2 475)、87.70%(2 751/3 137)、84.57%(2 356/2 786)，3组间比较差异均无统计学意义(n χ2＝3.786，n P＝0.151; n χ2＝2.177，n P＝0.377)。D、E组息肉检出率分别为36.16%(1 572/4 347)、41.61%(1 811/4 352)，检出小息肉个数占比分别为90.67%(4 390/4 842)、88.68%(4 928/5 557)，2组比较差异亦无统计学意义(n χ2＝2.934，n P＝0.087; n χ2＝2.416，n P＝0.120)。内镜精灵结肠镜检查组(D＋E组)与单纯结肠镜检查组(A＋B＋C组)比较，息肉检出率[38.89%(3 383/8 699)比23.95%(2 387/9 968), n χ2＝485.668，n P<0.001]、小息肉检出个数占比[89.60%(9 318/10 399)比86.54%(7 268/8 398),n χ2＝29.215，n P<0.001]差异均有统计学意义。n 结论:在电子结肠镜检查时应用内镜精灵，结肠息肉检出率显著提高，特别是小息肉检出率显著提高。“,”Objective:To explore the value of endoscopic elves in the detection of colonic polyps in colonoscopy.Methods:Data of 18 667 patients, who underwent electronic colonoscopy at center of digestive endoscopy, People′s Hospital of Wuhan University from November 2016 to December 2018 were analyzed retrospectively. According to different time period, patients were divided into five groups: group A were 3 131 cases (November 2016 to April 2017), group B 3 703 cases (May 2017 to September 2017), group C 3 134 cases (October 2017 to February 2018), group D 4 347 cases (March 2018 to July 2018), and group E 4 352 cases (August 2018 to December 2018). Simple electronic colonoscopy was performed only in group A, B and C, while endoscopic elves electronic colonoscopy was performed in group D and E. The detection rate of polyps, the number of large and small polyps were compared.Results:A total of 18 667 patients underwent electronic colonoscopy and 5 770 patients with 18 797 polyps were found. The detection rates of polyps in group A, B and C were 21.88% (685/3 131), 26.55% (983/3 703), and 22.94% (719/3 134), respectively, and the proportions of small polyps were 87.31% (2 161/2 475), 87.70% (2 751/3 137), and 84.57% (2 356/2 786), respectively, with no significant differences (n χ2=3.786, n P=0.151; n χ2=2.177, n P=0.377). There were also no significant differences between group D and group E in the detection rate of polyps [36.16% (1 572/4 347) VS 41.61% (1 811/4 352), n χ2=2.934, n P=0.087], or the proportion of small polyps [90.67% (4 390/4 842) VS 88.68% (4 928/5 557), n χ2=2.416, n P=0.120]. Compared with the simple colonoscopy group (group A+ B+ C), the detection rate of polyps [38.89% (3 383/8 699) VS 23.95% (2 387/9 968), n χ2=485.668, n P<0.001] and the proportion of small polyps [89.60% (9 318/10 399) VS 86.54% (7 268/8 398),n χ2=29.215, n P<0.001] in the endoscopic elves colonoscopy group were significantly higher.n Conclusion:The application of endoscopy elves in colonoscopy can increase the detection rate of colonic polyps, especially for small polyps.
