研究目的:

本研究的目的是评估口服4LPEG电解质溶液标准方案和甘油灌肠准备方案在急性左半结肠出血患者内镜检查前肠道准备清洁度效果差异。甘油灌肠剂是临床上常用的肠道清洁药物,具备价格低廉,适用人群广等优点,对于急性左半结肠出血患者具有潜在优势。目前对甘油灌肠剂的肠道准备效果缺乏系统性研究,与口服4LPEG电解质溶液标准方案对比研究其肠道准备真实效果具有极强现实意义。  

Objectives of Study:

The purpose of this study was to evaluate the difference in the effect of oral 4LPEG electrolyte solution standard protocol and glycerol enema preparation protocol on the cleanliness of bowel preparation before endoscopy in patients with acute left colon bleeding. Glycerin enema is a commonly used intestinal cleaning drug in clinical practice. It has the advantages of low price and wide application population, and has potential advantages for patients with acute left colon bleeding. At present, there is a lack of systematic research on the intestinal preparation effect of glycerol enema. It is of great practical significance to compare the real effect of intestinal preparation with the standard scheme of oral 4LPEG electrolyte solution.

干预措施:

使用口服PEG电解质溶液标准方案进行肠道准备。具体方法为:嘱受试者3-4小时内服用4LPEG电解质溶液,其中30分钟至1小时内快速饮用1500-2000ml,剩余在1-2小时内分次喝完。若受试者肠道准备完成后排出无色或淡黄清水样便,则在1-2小时内进行结肠镜检查。若受试者肠道准备完成后仍排出棕色粪水,可在内镜冲洗吸引下试行结肠镜检查,若进镜后评估左半结肠BBPS评分<2分或受试者因恶心、呕吐等不良反应未完成肠道准备,则予受试者甘油灌肠剂1支(110ml)进行补充肠道准备,具体方法同灌肠组,待受试者粪便排空后再次进镜检查。

干预措施代码:

Intervention:

Bowel preparation was performed using the standard protocol of oral PEG electrolyte solution. The specific method is as follows : the subjects were instructed to take 4LPEG electrolyte solution within 3-4 hours, of which 1500-2000 ml was quickly drunk within 30 minutes to 1 hour, and the remaining was drunk in 1-2 hours. If the subjects were discharged with colorless or yellowish water after bowel preparation, colonoscopy was performed within 1-2 hours. If the subject still discharges brown fecal water after the completion of intestinal preparation, colonoscopy can be performed under endoscopic irrigation and suction. If the BBPS score of the left colon is less than 2 points or the subject fails to complete intestinal preparation due to nausea, vomiting and other adverse reactions after entering the colonoscopy, the subject is given a glycerol enema ( 110ml ) for supplementary intestinal preparation, the specific method is the same as that of the enema group, and the colonoscopy is performed again after the feces of the subject are emptied.

Group B

Sample size:

干预措施:

使用甘油灌肠剂进行肠道准备。具体方法为:嘱受试者侧卧位插入肛门内(6-10 cm)。用力挤压容器,将药液缓慢注入直肠内,注完后将注入管缓缓拔出,然后用清洁棉球按住肛门1-2分钟,通常5-15分钟可以排便,一次使用1支(110ml),待受试者排空粪便,肠道准备完成后1-2小时内进行结肠镜检查。若进镜后评估左半结肠BBPS评分<2分,则加予受试者甘油灌肠剂1支(110ml)进行补充肠道准备,具体方法同前,待受试者粪便排空后再次进镜检查。

干预措施代码:

Intervention:

Glycerin enema was used for bowel preparation. The specific method is : ask the subject to insert the anus in the lateral position ( 6-10 cm ). The liquid was slowly injected into the rectum. After the injection, the injection tube was slowly pulled out, and then the anus was pressed with a clean cotton ball for 1-2 minutes. Usually 5-15 minutes can be defecated, using 1 ( 110ml ) at a time. When the subjects empty the feces, colonoscopy is performed within 1-2 hours after the bowel preparation is completed. If the BBPS score of the left colon was less than 2 points after entering the colonoscopy, 1 ( 110ml ) of glycerol enema was added to supplement the bowel preparation. The specific method was the same as before, and the colonoscopy was performed again after the feces of the subjects were emptied.
