摘　　要：目的对比靛胭脂染色和白光内镜对右半结肠息肉的检出率。方法选取2022年7月至2023年3月在成都市青白江区人民医院进行结肠镜检查的1052例患者为研究对象,将患者分为靛胭脂染色组和白光内镜组,每组526例。分别对右半结肠采用靛胭脂染色和白光模式观察,对比两种检查方法在右半结肠息肉检出率中的差异。结果与白光内镜组相比,靛胭脂染色组的右半结肠息肉检出率(41.6%)、腺瘤检出率(20.9%)、广基锯齿状病变检出率(2.1%)、增生性息肉检出率(20.3%)、巴黎分型0~Ⅱ型(平坦型病变)检出率(38.0%)、NICE 1型(色泽苍白型病变)检出率(22.2%)、直径<5 mm息肉检出率(30.5%)及病理活检符合率(86.4%)、特异度(84.7%)、灵敏度(88.2%)更高,差异有统计学意义(P<0.05)。白光内镜组与靛胭脂染色组在退镜时间上比较差异无统计学意义(t=1.407,P=0.160)。结论靛胭脂染色内镜检查对右半结肠息肉检出率更高,更易检出微小息肉及色泽苍白的平坦型息肉病变。Objective To compare the detection rate of right hemicolonic polyp between indigo carmine staining and white light endoscopy.Methods A total of 1052 patients with colonoscopic examination in Qingbaijiang District People’s Hospital of Chengdu City from July 2022 to March 2023 were selected as the study subjects and divided into the indigo carmine staining group and white light endoscopy group,526 cases in each group.The right hemicolon was observed by indigo carmine staining and white light pattern respectively.The difference in the detection rate of right hemicolonic polyp was compared between the two detection methods.Results Compared with the white light endoscopic examination group,the detection rate of the right hemicolonic polyp(41.6%),detection rate of the right hemicolon adenoma(20.9%),detection rate of wide basal serrated lesion(2.1%),detection rate of proliferative polyps(20.3%),detection rate of Paris type 0-Ⅱ(38.0%),detection rate of NICE 1 type(pale lesion,22.2%),detection rate of polyps with a diameter<5 mm(30.5%)and the consistency rate of pathological biopsy(86.4%),specificity(84.7%)and sensitivity(88.2%)in the indigo carmine staining group were higher,and the differences were statistically significant(P<0.05).There was no statistical difference in the duration of mirror withdrawal between the white light endoscopy group and the indigo carmine staining group(t=1.407,P=0.160).Conclusion The endoscopic examination with indigo carmine staining has a higher detection rate for right hemicolonic polyp,and is easier to detect micropolyps and flat polyps with pale color.
