     [摘要]目的 比较I-SCAN技术和普通高清电子结肠镜在结直肠息肉诊断中的应用效果。方法 选取2016年3～10月在我院行结肠镜检查的86例患者作为研究对象，随机分为实验组和对照组，各43例。实验组采用I-SCAN模式检查，对照组采用普通高清模式检查。比较两组的结直肠息肉及腺瘤检出率、内镜下病理诊断和病理活检结果的符合率、退镜时间和肠道清洁度。结果 实验组的息肉检出率为58.14%，显著高于对照组的37.21%，差异有统计学意义(P<0.05)。实验组的腺瘤检出率为34.89%，显著高于对照组的25.58%，差异有统计学意义(P<0.05)。实验组结肠镜下病理诊断和病理活检结果的总符合率为95.00%，显著高于对照组的55.56%，差异有统计学意义(P<0.05)。两者的退镜时间和肠道清洁度比较，差异无统计学意义(P>0.05)。结论 结肠镜采用I-SCAN技术可使息肉和腺瘤的检出率更高，内镜下的病理类型的确诊率更高，且检查时间并未明显延长，值得临床推广应用。

    [Abstract]Objective To compare the application effect of I-SCAN technology and common high definition (HD) electronic colonoscopy in the diagnosis of colorectal polyps.Methods 86 patients underwent colonoscopy in our hospital from March to October in 2016 were selected and randomly divided into the experimental group and the control group，43 cases in each group.The experimental group was given I-SCAN mode，and the control group was given ordinary HD model.The detection rates of colorectal polyps and adenomas，the coincidence rate of endoscopic pathological diagnosis and pathological biopsy results，the time of removing the endoscope and the degree of intestinal cleanliness in the two groups were compared.Results The detection rate of polyps in the experimental group was 58.14%，which was higher than 37.21% in the control group，with significant difference (P<0.05).The detection rate of adenoma in the experimental group was 34.89%，which was higher than that in the control group (25.58%)，with significant difference (P<0.05).The total coincidence rate of colonoscopy pathological diagnosis and pathological biopsy in the experimental group was 95.00%，which was higher than that in the control group (55.56%)，with significant difference (P<0.05).There was no significant difference between the two groups in the time of removing the endoscope and the degree of intestinal cleanliness (P>0.05).Conclusion Colonoscopy with I-SCAN technology can make the higher detection rate of polyps and adenomas，the endoscopic diagnosis rate of pathological type is higher，and the examination time has not been significantly prolonged，it is worthy of clinical promotion and application.

    結直肠息肉是发生在结直肠黏膜上的常见良性肿瘤，研究显示，其发病原因与粪便的慢性刺激密切相关[1]。本病患者大多以无明显诱因的腹痛、腹泻、黏液脓血便来院就诊[2]，通常采用电子结肠镜检查，并通过病理活检确定病理类型[3]，但病理活检等待时间较长，容易延误病情，错过最佳的治疗时期[4]。随着现代内镜技术的不断发展，具有操作简单、可重复性强、不使用染色剂等优点的I-SCAN技术得到推广和应用[5]，但目前对其检查结直肠息肉的研究仍不透彻。本研究通过探讨I-SCAN对结直肠息肉的检出率和病理类型的确诊率，进而判定诊断效果。 (黎波 刘扬兰 张宗胜)
