老年慢性便秘患者不同肠道准备方法应用评价

采用随机单盲法将146例需要行电子结肠镜检查的老年慢性便秘患者随机分为治疗组和对照组。治疗组肠道准备方法采用检查前1d口服四磨汤20ml、3次／d后，服用聚乙二醇电解质散3L；对照组直接服用聚乙二醇电解质散3L。并由内镜操作医师应用Boston肠道准备量表对肠道准备效果进行评估。结果显示，治疗组患者首次大便时间短于对照组（P〈0．05），两组排便次数及不良反应发生率差异无统计学意义（P〉0．05）。治疗组Boston肠道准备量表评分优于对照组（P〈0．05）。提示联用四磨汤和聚乙二醇电解质散对老年慢性便秘患者进行肠道准备可提高其效果。

Different methods for bowel preparation in elderly patients with constipation before colonoscopy

One hundred and forty six elderly patients with constipation undergoing colonoscopy during March 2012 and August 2013 were randomly assigned to trial and control groups. Seventy patients in trial group received Macrogol electrolytes powder combined with Chinese herb medicine Simo decoction for bowel preparation and 76 patients in control group received macrogol electrolytes powder only. The first defecation, times of defecation and tolerance of patients were compared between two groups. The quality of bowel preparation was evaluated by endoscopists with Boston Bowel Preparation Scale （ BBPS ）. The first defecation time was shorter in trial group than that in control group （ 55.7 ± 27.9 vs. 72.9 ± 34. 8, P 〈 0. 05 ） . However, no statistical significance was found in the times of defecation and tolerance of patients between two groups. The mean BBPS score in trial groups was higher than that in control group （7.87±1.08 vs. 6. 97 ±0. 96, P 〈 0.05 ）. Chinese herb medicine Simo decoction combined with conventional method shows satisfactory result for bowel preparation in elderly patients with constipation undergoing colonoscopy.
