Abstract： 背景:常规注气结肠镜检查最为困难的部分在左半结肠,插镜过程中患者可有明显不适,有研究报道水交换技术可明显减轻内镜检查过程中患者的疼痛和不适感,然而,左半结肠水交换技术与常规注气比较效果如何,目前与之相关的研究尚少.目的:比较左半结肠水交换(water exchange,WE)结肠镜与常规注气(air insufflation,AI)结肠镜检查的临床应用效果.方法:2020-06/2020-12,至我院消化内镜中心行结肠镜检查的连续患者,符合纳入标准的患者,按照随机数字表以(1∶1)进行随机分为左半结肠WE组与常规AI组,记录两组的盲肠插镜成功率,到达盲肠的进镜时间,退镜时间,腺瘤检出率(adenoma detection rate,ADR),疼痛视觉模拟评分(visual analogue scale,VAS),穿孔等检查相关并发症.结果:根据纳入与排除标准,共筛选出276例患者,其中左半结肠WE组139例,常规AI组137例,两组盲肠插镜成功率、退镜时间以及腺瘤检出率差异无统计学意义,但左半结肠WE组较常规越组进镜时间明显缩短(4.6 min vs 5.3 min;P＜0.05),VAS评分更低(2.7 min vs 3.3 min;P＜0.05),两组间均无穿孔等检查相关并发症发生.结论:左半结肠水交换结肠镜较常规注气结肠镜检查明显缩短进镜时间,减轻患者的疼痛和不适,值得临床选择使用.
