非麻醉肠镜失败的相关因素分析

Related factors predicting unsuccessful colonoscopy without sedation

目的在中国大部分地区由于医疗资源配备不足和经济相对落后,肠镜检查仍然是以非麻醉为主。该研究致力于调查导致非麻醉肠镜失败的相关因素。方法对2014年4月-2015年1月在苏州大学附属第二医院接受非麻醉肠镜检查的患者进行前瞻性研究,调查项目包括患者因素[年龄、性别、体质指数(BMI)、文化水平、清肠药物、曾经做过肠镜次数、平时排便习惯、既往慢性疾病史、近半年体育运动情况、既往腹盆腔手术史、本次肠镜检查原因、近半年情绪情况、清肠效果和结肠憩室],内镜医师因素(肠镜操作年限、插镜方式)。将这些因素进行相关分析,探讨非麻醉肠镜失败的相关因素。结果该研究最终纳入1 726例患者,其中男927例,女799例,患者的平均年龄为50.04岁,盲肠到达率为91.6%。多因素Logistic回归分析发现高龄、低BMI、便秘、情绪焦虑、肠道准备差是患者非麻醉肠镜检失败的相关因素。结论导致非麻醉肠镜失败的相关因素有高龄、低BMI、便秘、情绪焦虑、肠道准备差。在临床上,可以进一步制定筛查指标来提高患者非麻醉肠镜检查成功率。

Objective To find the related factors of the unsuccessful unsedated colonoscopy. Methods Clinical data of 1 726 consecutive subjects who underwent colonoscopy without sedation from April 2014 to January 2015 at the second affiliated hospital of Soochow university were analyzed. Data included characteristics of the patients （age, gender, body mass index, degree of education, the bowel-cleaning drugs, previous colonoscopy experience, bowel habits, history of chronic disease, history of sport, history of abdominal or pelvic surgery, the indication of colonoscopy, mood, quality of bowel preparation, and presence/absence of colonic diverticulum）, the characteristics of the physicians （procedure experience, the instrument handling method）. These factors were analyzed to evaluate their impact on result of unsedated colonoscopy. Results This study included 1 726 patients （male/female： 927/799）. These patients＂ average age was 50.04 years old, the cecal intubation rate was 91.6%, and the average intubation time was 10.27 minutes. The multiple regression analysis showed the elderly patient, lower BMI, irritability, constipation, poor bowel preparation were associated with the lower cecal intubation rate. Conclusions The elderly patient, lower BMI, irritability, constipation and poor bowel preparation were associated with the failure of unsedated colonoscooy. In clinical practice, quality improvement programs are needed to improve the rate of total colonoscopy.
