Study design:

Parallel 

研究目的:

1.主要目标: 明确Omega-3联合UDCA较单药更显著改善胆管结石术后患者胆汁酸谱(胆固醇结晶评分CCS降低≥50%)及炎症指标(CRP 降幅≥40%) 2.次要目标:明确联合用药对胆管结石术后患者胆汁酸谱及粪便肠道菌群变化的影响。 3.建设性目标:建立基于胆汁酸谱、炎症因子(IL-6或TNF-α)降幅的疗效预测模型。  

Objectives of Study:

Primary Objective:To demonstrate that the combination of Omega-3 and UDCA, compared with monotherapy, leads to a more significant improvement in bile acid profile (defined as a reduction of ≥50% in cholesterol crystal score, CCS) and inflammatory markers (defined as a ≥40% decrease in C-reactive protein, CRP) in patients after biliary stone surgery.Secondary Objectives:To investigate the effects of the combination therapy on changes in bile acid profile and fecal gut microbiota in post-surgical biliary stone patients.Exploratory Objective:To develop a predictive efficacy model based on reductions in bile acid profile and inflammatory cytokines (e.g., IL-6 or TNF-α).
