Abstract:

Objective　To investigate the effect of bowel preparation protocol on the efficiency of colonoscopy based on Bristol stool characters typing. Methods　A randomized controlled trial was conducted on 88 patients scheduled for colonoscopy at the Second Affiliated Hospital of Xi'an Medical University from October 2020 to September 2022. The patients were divided into an observation group (44 cases) and a control group (44 cases) using the random number table method. In the control group, there were 22 males and 22 females, aged (48.71±3.44) years. In the observation group, there were 21 males and 23 females, aged (48.55±3.40) years. The control group received standard bowel preparation protocol, while the observation group received bowel preparation protocol based on Bristol stool characters typing. The success rate of bowel preparation, colon cleanliness [Boston Bowel Preparation Scale (BBPS)], colonoscope insertion time, and overall examination time were compared between the two groups after receiving different bowel preparation schemes. t test and χ² test were used. Results　The qualified rate of bowel preparation in the observation group was higher than that in the control group [79.55% (35/44) vs. 47.73% (21/44)], with a statistically significant difference (χ²=9.625, P=0.002). The BBPS scores for the right, middle, and left colon sections of the observation group were higher than those of the control group [(2.11±0.69) points vs. (1.71±0.52) points, (2.31±0.48) points vs. (1.95±0.57) points, (2.29±0.47) points vs. (1.99±0.67) points], and the colonoscope insertion time and overall examination time were shorter than those of the control group [(11.20±0.85) min vs. (11.62±1.05) min, (15.17±1.24) min vs. (16.28±1.73) min], with statistically significant differences (t=3.071, P=0.003; t=3.205, P=0.002; t=2.432, P=0.017; t=2.062, P=0.042; t=3.459, P=0.001). Conclusion　Bowel preparation protocol based on Bristol stool characters typing significantly optimizes the efficiency and quality of colonoscopy by improving the success rate of bowel preparation and colon cleanliness, as well as reducing the colonoscope insertion time and overall examination time, offering a more effective bowel preparation method for clinical practice.

摘要：

目的　研究基于Bristol粪便性状分型的肠道准备方案对结肠镜检查效率的影响。方法　选取西安医学院第二附属医院于2020年10月至2022年9月收治的88例拟行结肠镜检查患者进行随机对照试验，按照随机数字表法分为观察组和对照组，每组44例。对照组男22例、女22例，年龄（48.71±3.44）岁，实施常规肠道准备方案；观察组男21例、女23例，年龄（48.55±3.40）岁，实施基于Bristol粪便性状分型的肠道准备方案。对比两组患者接受不同肠道准备方案后肠道准备成功率、结肠清洁度［Boston肠道准备量表（BBPS）］、结肠进镜时间、整体检查时间。采用t检验、χ²检验。结果　观察组肠道准备合格率高于对照组［79.55%（35/44）比47.73%（21/44）］，差异有统计学意义（χ²=9.625，P=0.002）；观察组的右侧、中间、左侧BBPS评分均高于对照组［（2.11±0.69）分比（1.71±0.52）分、（2.31±0.48）分比（1.95±0.57）分、（2.29±0.47）分比（1.99±0.67）分］，结肠进镜时间、整体检查时间均短于对照组［（11.20±0.85）min比（11.62±1.05）min、（15.17±1.24）min比（16.28±1.73）min］，差异均有统计学意义（t=3.071、P=0.003，t=3.205、P=0.002，t=2.432、P=0.017，t=2.062、P=0.042，t=3.459、P=0.001）。结论　基于Bristol粪便性状分型的肠道准备方案能提高肠道准备成功率和结肠清洁度，缩短结肠进镜和整体检查时间，显著优化了结肠镜检查的效率和质量，为临床提供了一种更有效的肠道准备方法。
