研究目的:

本研究旨在评估熊去氧胆酸和/或双歧杆菌干预能否改善胆囊切除术后有症状患者的“肠道菌群-胆汁酸-免疫”轴功能,在人体层面验证该致癌通路假设的可调控性。共同主要目的包括: (1)评价干预6个月后粪便次级胆汁酸比例较基线的变化; (2)评价干预后胆囊切除术后综合征核心症状综合评分的改善情况。次要目的在于评估干预对患者生活质量、外周血调节性T细胞比例、血清FGF19水平的影响,并分析菌群-胆汁酸-免疫-临床指标之间的相关性,同时评价干预的安全性与耐受性。本研究旨在为将来以“结直肠癌发生”为终点的长期预防性试验提供关键的效应量数据和生物标志物依据,推动胆囊切除术后高危人群的精准预防策略。  

Objectives of Study:

This study aims to evaluate whether ursodeoxycholic acid and/or Bifidobacterium intervention can improve the function of the "gut microbiota–bile acid–immune" axis in symptomatic patients after cholecystectomy, thereby testing the modifiability of this carcinogenic pathway hypothesis in humans. The co-primary objectives are: (1) to evaluate the change from baseline in fecal secondary bile acid proportion after 6 months of intervention; (2) to evaluate the improvement in postcholecystectomy syndrome core symptom composite score. Secondary objectives are to assess the effects of the intervention on quality of life, peripheral blood regulatory T cell proportion, and serum FGF19 level; to analyze the correlations among microbiota, bile acid, immune, and clinical indicators; and to evaluate the safety and tolerability of the 6-month intervention. This study is designed to provide key effect size data and biomarker evidence for future large-scale long-term preventive trials with colorectal cancer occurrence as the endpoint, ultimately advancing precision prevention strategies for high-risk post-cholecystectomy populations.

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

An internet-based electronic data capture system is used for online collection and real-time entry of all clinical data and some questionnaire data, with support for audit trails, logic checks, and authority management. Raw data generated from laboratory tests are managed by the central laboratory information system, and analyzed result data are imported into the electronic data capture system after review. Key variables including primary endpoint data and serious adverse event descriptions undergo independent secondary verification and review by a second authorized researcher under blinded conditions.
