行走功能状态与老年人结肠镜检查前肠道准备的相关性

Correlation between walking function and bowel preparation for colonoscopy in the elderly patients

目的探讨老年人行走功能状态与结肠镜检查前肠道准备质量的关系。方法选取2017年1月至2018年3月北京老年医院消化科住院期间行结肠镜检查的153例老年患者。检查前通过Barthel指数评价患者行走功能,并根据行走是否独立将患者分为行走正常组82例及行走困难组71例。2组患者采取相同的肠道准备方法,记录肠道清洁完成情况并计算清洁有效率。采用SPSS 19.0统计软件进行分析。根据数据类型,组间比较采用独立样本t检验或χ2检验。相关性分析采用Spearman秩相关检验。结果与行走困难组比较,行走正常组患者完整服用肠道清洁剂的比例显著升高[87.8%(72/82) vs63.4%(45/71),P<0.01]。而在未完整服用肠道清洁剂的患者中,与行走困难组比较,行走正常组患者因不能忍受频繁排便的比例显著降低,差异有统计学意义[8.54%(7/82) vs 30.99%(22/71),P=0.001],但因不良反应导致未完整服用肠道清洁剂的比例2组差异无统计学意义[3. 66%(3/82) vs 5. 63%(4/71),P=0.705]。Spearman秩相关分析显示,行走功能状态与肠道准备清洁质量呈正相关(r=0.333,P<0.01)。结论老年患者行走功能状态与结肠镜检查前肠道准备质量相关,行走困难影响患者肠道准备质量。

Objective To investigate the correlation between the walking function status and the quality of bowel preparation for colonoscopy in the elderly patients.Methods Enrolled in this study were 153 elderly inpatients undergoing colonoscopy in our hospital from January 2017 to March 2018.Assessment of the walking function was performed using the Barthel index before the procedure,and the patients were divided into normal walking group(n=82)and abnormal walking group(n=71)based on walking independence.The same bowel preparation was performed for both groups,and intestinal cleansing was recorded and cleaning efficiency was calculated.SPSS statistics 19.0 was used for analysis.Depending on data type,independent sample t test or Chi-square test was used for com-parison between groups.Correlation analysis was performed using Spearman rank correlation test.Results Significantly more patients in the normal walking group than in the abnormal walking group[87.8%(72/82)vs 63.4%(45/71),P<0.01]finished intestinal cleanser.In the patients who did not finish intestinal cleanser,the proportion of those intolerant frequent defecation in the normal walking group was significantly lower than that in the abnormal walking group[(8.54%(7/82)vs 30.99%(22/71),P=0.001].However,the proportion of those who did not finish intestinal cleanser due to adverse reactions had no statistically significant difference between the 2 groups[3.66%(3/82)vs 5.63%(4/71),P=0.705].Spearman rank correlation analysis showed that walking function was positively correlated with intestinal cleanliness(r=0.333,P<0.01).Conclusion Walking function status is correlated to the quality of bowel preparation in the elderly patients before colonoscopy.Difficulty in walking affects the quality of bowel preparation.
