研究目的:

研究主要目的:通过比较三组的肠道准备合格率,探讨TEAS是否能增强标准3L PEG的肠道清洁效果,以及TEAS联合减量2L PEG方案是否能维持与标准3L PEG方案相当的肠道清洁质量。次要目的:评估三组在肠道准备期间不良反应发生率(恶心、呕吐、腹胀等)、患者满意度、耐受性及依从性、腺瘤检出率等方面的差异;同时收集操作可行性、盲法实施难度及依从性数据,为正式试验的样本量计算、方案优化及盲法设计提供依据。  

Objectives of Study:

To investigate, through comparison of bowel preparation adequacy rates among the three groups, whether transcutaneous electrical acupoint stimulation (TEAS) can enhance the bowel cleansing efficacy of standard 3L polyethylene glycol (PEG) regimen, and whether the TEAS combined with reduced-dose 2L PEG regimen can achieve bowel cleansing quality comparable to that of the standard 3L PEG regimen. To evaluate the differences among the three groups in terms of adverse event rates (e.g., nausea, vomiting, abdominal distension) during bowel preparation, patient satisfaction, tolerability, adherence, and adenoma detection rate. Additionally, to collect data on operational feasibility, blinding implementation difficulty, and adherence, thereby providing a basis for sample size calculation, protocol optimization, and blinding design in the subsequent definitive trial.
