| 1 | 口服磷酸钠盐在肠镜检查前肠道准备中的应用研究进展显示文摘肠镜检查是诊断、干预治疗肠道疾病最常用、有效的检查方法之一,是调查评价肠道黏膜的金标准^[1]。在结肠镜检查中.肠道清洁程度对肠镜检查效果起决定性作用。清洁的肠道为顺利插镜、观察结肠黏膜、准确取得活组织标本、经肠镜切除息肉等诊疗活动顺利进行提供了基本的条件, | 何丽 郭秀君 洪艳燕 杜永红 刘萍 吴建霞 | 2012 | 中华护理杂志2012，47，11： | 43 |
| 2 | Achieving the best bowel preparation for colonoscopy显示文摘Bowel preparation is a core issue in colonoscopy,as it is closely related to the quality of the procedure.Patients often find that bowel preparation is the most unpleasant part of the examination.It is widely accepted that the quality of cleansing must be excellent to facilitate detecting neoplastic lesions.In spite of its importance and potential implications,until recently,bowel preparation has not been the subject of much study.The most commonly used agents are high-volume polyethylene glycol(PEG)electrolyte solution and sodium phosphate.There has been some confusion,even in published meta-analyses,regarding which of the two agents provides better cleansing.It is clear now that both PEG and sodium phosphate are effectivewhen administered with proper timing.Consequently,the timing of administration is recognized as one of the central factors to the quality of cleansing.The bowel preparation agent should be administered,at least in part,a few hours in advance of the colonoscopy.Several low volume agents are available,and either new or modified schedules with PEG that usually improve tolerance.Certain adjuvants can also be used to reduce the volume of PEG,or to improve the efficacy of other agents.Other factors apart from the choice of agent can improve the quality of bowel cleansing.For instance,the effect of diet before colonoscopy has not been completely clarified,but an exclusively liquid diet is probably not required,and a low-fiber diet may be preferable because it improves patient satisfaction and the quality of the procedure.Some patients,such as diabetics and persons with heart or kidney disease,require modified procedures and certain precautions.Bowel preparation for pediatric patients is also reviewed here.In such cases,PEG remains the most commonly used agent.As detecting neoplasia is not the main objective with these patients,less intensive preparation may suffice.Special considerations must be made for patients with inflammatory bowel disease,including safety and diagnostic issues,so that the most adequate agent is chosen.Identifying neoplasia is one of the main objectives of colonoscopy with these patients,and the target lesions are often almost invisible with white light endoscopy.Therefore excellent quality preparation is required to find these lesions and to apply advanced methods such as chromoendoscopy.Bowel preparation for patients with lower gastrointestinal bleeding represents a challenge,and the strategies available are also reviewed here. | Adolfo Parra-Blanco Alex Ruiz Manuel Alvarez-Lobos Ana Amorós Juan Cristóbal Gana Patricio Ibáez Akiko Ono Takahiro Fujii | 2014 | World Journal of Gastroenterology2014，20，47： | 37 |
| 3 | 磷酸钠盐不同服用时间在胃肠镜检查前肠道准备中的效果分析显示文摘目的:探讨磷酸钠盐不同服用时间在胃肠镜检查前肠道准备中的应用效果。方法:选取2014年1-6月在笔者所在医院健康研究院接受胃肠镜检查患者200例,按照随机数字表法分成对照组和观察组,每组100例。两组均选取磷酸钠盐溶液90 ml加温开水稀释至1500 ml,对照组于检查当天早上5∶00-7∶00开始连续服用1500 ml;观察组在检查前一个晚上服1次,每次750 ml,检查当天早上5∶00服用剩余750 ml。比较两组肠道清洁度分级、清洁范围的分度以及不良反应。结果:两组患者肠道清洁度分级比较差异均无统计学意义(P>0.05)。两组患者肠道清洁范围分度比较差异均无统计学意义(P>0.05)。观察组不良反应显著少于对照组,两组患者不良反应发生率比较差异有统计学意义(P<0.05)。结论:在胃肠镜检查前肠道准备中,磷酸钠盐不同服用时间对肠道清洁度分级、清洁范围的分度影响不大,但连续太量服用容易发生不良反应,因此建议在肠道准备中将分次服用磷酸钠盐。 | 刘娜 杨英 李洁冲 | 2014 | 中外医学研究2014，12，33： | 5 |
| 4 | 结肠镜检查肠道准备研究现状(综述)显示文摘该文通过检索国内外结肠镜检查前肠道准备的各种方法以及一些特殊群体肠道准备方法,列举了判断肠道清洁度的三种标准,阐明信度最高、最客观真实的标准是使用Boston肠道准备量表,呼吁临床医护人员在给患者行结肠镜检查时应充分考虑个体差异,采取个体化准备方案。 | 阳凤 班春景 杨李荣 高玉霞 | 2015 | 安徽卫生职业技术学院学报2015，14，5： | 5 |
| 5 | 三种方法用于高龄男性结肠镜检查前肠道准备效果观察显示文摘目的:观察三种方法对高龄男性结肠镜检查前肠道准备的效果及安全性,探索适合高龄老年人肠道清洁方法。方法:选取拟行结肠镜检查的高龄男性117例,随机分为A组35例、B组42例和C组40例。A组服用硫酸镁溶液;B组服用复方聚乙二醇4000散(PEG);C组服用PEG+枸橼酸莫沙必利。观察比较3组排便情况、肠道清洁效果和不良反应发生情况。结果:C组首次排便时间和最后一次排便时间显著短于A组和B组(P<0.05)。3组排便次数差异不显著(P>0.05)。C组清洁效果、舒适度显著好于A组和B两组(P<0.05)。A组发生不良反应17例(48.6%),B组为20例(47.6%),C组为9例(22.5%);C组与A组和B组比较,均差异非常显著(P<0.01)。结论:PEG+枸橼酸莫沙必利用于高龄男性老人结肠镜检查前的肠道准备,清洁效果好、舒适度高、不良反应发生率低。 | 王吉 胡智 伏婷婷 朱哲宇 付思齐 李勇 王津 | 2016 | 人民军医2016，59，2： | 4 |
| 6 | Colometer:A real-time quality feedback system for screening colonoscopy显示文摘AIM:To investigate the performance of a new software-based colonoscopy quality assessment system.METHODS:The software-based system employs a novel image processing algorithm which detects the levels of image clarity,withdrawal velocity,and level of the bowel preparation in a real-time fashion from live video signal.Threshold levels of image blurriness and the withdrawal velocity below which the visualization could be considered adequate have initially been determined arbitrarily by review of sample colonoscopy videos by two experienced endoscopists.Subsequently,an overall colonoscopy quality rating was computed based on the percentage of the withdrawal time with adequate visualization(scored 1-5;1,when the percentage was 1%-20%;2,when the percentage was 21%-40%,etc.).In order to test the proposed velocity and blurriness thresholds,screening colonoscopy withdrawal videos from a specialized ambulatory colon cancer screening center were collected,automatically processed and rated.Quality ratings on the withdrawal were compared to the insertion in the same patients.Then,3 experienced endoscopists reviewed the collected videos in a blinded fashion and rated the overall quality of each withdrawal(scored 1-5;1,poor;3,average;5,excellent) based on 3 major aspects:image quality,colon preparation,and withdrawal velocity.The automated quality ratings were compared to the averaged endoscopist quality ratings using Spearman correlation coefficient.RESULTS:Fourteen screening colonoscopies were assessed.Adenomatous polyps were detected in 4/14(29%) of the collected colonoscopy video samples.As a proof of concept,the Colometer software rated colonoscope withdrawal as having better visualization than the insertion in the 10 videos which did not have any polyps(average percent time with adequate visualization:79% ± 5% for withdrawal and 50% ± 14% for insertion,P < 0.01).Withdrawal times during which no polyps were removed ranged from 4-12 min.The median quality rating from the automated system and the reviewers was 3.45 [interquartile range(IQR),3.1-3.68] and 3.00(IQR,2.33-3.67) respectively for all colonoscopy video samples.The automated rating revealed a strong correlation with the reviewer's rating(ρ coefficient= 0.65,P = 0.01).There was good correlation of the automated overall quality rating and the mean endoscopist withdrawal speed rating(Spearman r coefficient= 0.59,P = 0.03).There was no correlation of automated overall quality rating with mean endoscopists image quality rating(Spearman r coefficient= 0.41,P = 0.15).CONCLUSION:The results from a novel automated real-time colonoscopy quality feedback system strongly agreed with the endoscopists' quality assessments.Further study is required to validate this approach. | Dobromir Filip Xuexin Gao Leticia Angulo-Rodriguez Martin P Mintchev Shane M Devlin Alaa Rostom Wayne Rosen Christopher N Andrews | 2012 | World Journal of Gastroenterology2012，18，32： | 2 |
| 7 | 肠镜检查术前肠道准备的方法护理进展显示文摘对肠镜检查术前肠道准备的方法护理进展进行研究。肠道准备是在进行肠镜检查术前进行的重要步骤。在实施肠镜检查术前,如果准备不足会导致粪便污染镜面,影响手术时的观察,甚至有可能会导致漏诊和误诊。手术前的准备方法较多,根据患者自身的情况选择一种清理较好地方法可以减少对身体的影响,有利于手术的进行。 | 肖良翠 | 2013 | 齐齐哈尔医学院学报2013，34，14： | 1 |
