结肠镜检查患者肠道准备失败发生现状及危险因素分析

Analysis of Present Situation and Risk Factors of Bowel Preparation Failure in Patients Undergoing Colonoscopy

目的:探讨分析结肠镜检查患者肠道准备失败发生现状及危险因素。方法:将87例结肠镜检查患者作为研究参与者,使用波士顿肠道准备评分量表(BBPS)对所有结肠镜检查患者进行评估,采用单因素及Logistic多因素回归分析结肠镜检查患者肠道准备失败的相关危险因素。结果:87例结肠镜检查患者BBPS量表评分为4~8分,平均(6.12±0.65)分,其中肠道准备失败者27例(31.03%);单因素分析显示有无合并糖尿病、药物剂量是否准确、服用后排便次数、有无合并腹部手术史、是否严格控制饮食类型存在显著性差异(P<0.05);Logistic多因素回归分析显示,结肠镜检查患者肠道准备失败的独立危险因素包括药物剂量不准确、服药后排便次数≤5次、合并糖尿病、合并腹部手术史和未严格控制进食类型(P<0.05)。结论:结肠镜检查患者肠道准备情况总体欠佳,药物剂量不准确、服药后排便次数≤5次、合并糖尿病、合并腹部手术史、未严格控制进食类型为结肠镜检查患者肠道准备失败的独立危险因素。

Objective To investigate the present situation and risk factors of bowel preparation failure in patients undergoing colonoscopy.Methods Total 87patients undergoing colonoscopy were enrolled as the study participants.All patients were evaluated using Boston bowel preparation scale(BBPS).Univari-ate and Logistic multivariate regression were used to analyze the risk factors of bowel preparation failure in patients undergoing colonoscopy.Results The BBPS scores of 87patients were 4~8points,with an av-erage of(6.12±0.65)points,among which 27cases(31.03%)failed in bowel preparation.Univariate a-nalysis showed that there were significant differences in whether the patients were combined with diabetes mellitus(DM),whether the drug dose was accurate,the frequency of bowel movements after medication,whether the patients had a history of abdominal operation,and whether the diet type was strictly con-trolled(P<0.05).Logistic multivariate regression analysis showed that the independent risk factors for bowel preparation failure in patients undergoing colonoscopy included inaccurate drug dose,less than 5 times of bowel movements after medication,combined DM,combined history of abdominal operation,and failure to strictly control diet type(P<0.05).Conclusion The overall poor bowel preparation of pa-tients undergoing colonoscopy,inaccurate drug dose,less than 5times of bowel movements after medica-tion,combined DM,combined history of abdominal operation,and failure to strictly control diet type are the independent risk factors for bowel preparation failure of patients undergoing colonoscopy.
