研究目的:

研究目的 通过比较乳果糖与3L PEG两种肠道清洁剂的效果,为制定一种高效、安全、耐受性良好的个性化肠道清洁方案提供临床数据支持,从而提高结肠镜检查的质量与患者满意度。 1 主要目的 了解临床实践中乳果糖口服液在中国人群中应用于结肠镜检查前肠道准备的有效性 2 次要目的 (1)了解临床实践中受试者对于乳果糖口服液进行结肠镜检查肠道准备的病变检出率。 (2)了解临床实践中乳果糖口服液进行结肠镜检查前肠道准备的排便特征。 (3)了解临床实践中受试者对于乳果糖口服液进行肠道准备的依从性。 3 探索性目的 了解临床实践中乳果糖口服液进行肠道准备欠佳肠道准备的影响因素。  

Objectives of Study:

Research Objectives To compare the efficacy of lactulose and 3L PEG as bowel cleansers, and to provide clinical data support for developing a personalized bowel preparation regimen that is highly effective, safe, and well-tolerated. This will enhance the quality of colonoscopy and patient satisfaction. 1 Primary Objective To assess the efficacy of lactulose oral solution in bowel preparation for colonoscopy in the Chinese population within clinical practice. 2 Secondary Objectives (1) To determine the lesion detection rate when using lactulose oral solution for bowel preparation in clinical practice. (2) To characterize the defecation features when using lactulose oral solution for bowel preparation in clinical practice. (3) To evaluate patient compliance with lactulose oral solution for bowel preparation in clinical practice. 3 Exploratory Objective To identify factors that may influence inadequate bowel preparation when using lactulose oral solution in clinical practice.

随机方法(请说明由何人用什么方法产生随机序列):

所有入组患者将根据计算机生成的随机分组表,随机分配至乳果糖组或PEG组,两组的分配比例为1:1。乳果糖组将服用200ml乳果糖溶液与300ml温水混合液,并随后服用1L温水;PEG组将分次服用3L PEG溶液。

Randomization Procedure (please state who generates the random number sequence and by what method):

All enrolled patients will be randomly assigned to either the lactulose group or the PEG group according to a computer-generated randomization schedule, with an allocation ratio of 1:1. Patients in the lactulose group will take a mixture of 200 ml lactulose solution and 300 ml warm water, followed by 1 L of warm water. Patients in the PEG group will take 3 L of PEG solution in divided doses.
